Description

La présente invention concerne les dispositifs d'affichage destinés à équiper des mouvements de montres du type comportant un train d'engrenages de finissage et une source d'énergie assurant l'entraînement de ce train d'engrenages. Ce dispositif comporte :

  • un disque d'affichage, et
  • un rouage d'affichage associé à une fonction complémentaire et dont un mobile porte le disque.
The present invention relates to display devices for equipping watch movements of the type comprising a finishing gear train and a power source for driving this gear train. This device comprises:
  • a display disk, and
  • a display gear associated with a complementary function and a mobile carries the disc.

Dans la présente description, on entend par disque une pièce ronde, généralement en plastique ou en métal, qui peut être percée ou non en son centre et porte des indications à afficher.In the present description, the term disc is a round piece, usually plastic or metal, which can be pierced or not in its center and carries indications to display.

L'affichage d'une information au moyen d'un ou plusieurs disques est connu de l'homme du métier. Une des applications les plus fréquentes concerne l'indication du jour et de la date, l'affichage se faisant au moyen de deux disques, lesquels effectuent un saut par jour. Pour assurer ce saut, le mouvement est généralement muni d'un ressort, armé par le rouage de finissage, et qui se détend vers minuit, faisant ainsi passer la date et le jour à l'indication suivante. Il peut également être entraîné dans un premier temps dans un mouvement lent assuré par le rouage de la montre, puis par un saut engendré par un sautoir.The display of information by means of one or more disks is known to those skilled in the art. One of the most frequent applications concerns the indication of the day and the date, the display being done by means of two disks, which make a jump per day. To ensure this jump, the movement is generally provided with a spring, armed by the finishing train, and which relaxes around midnight, thus changing the date and the day to the following indication. It can also be driven in a first time in a slow movement ensured by the cogwheel of the watch, then by a jump generated by a jumper.

Lorsque l'information change plus fréquemment qu'une fois par jour, le mécanisme devient plus délicat dans son fonctionnement, l'énergie disponible pour chaque saut étant sensiblement réduite. Ce problème peut être résolu en entraînant les disques en continu, comme proposé dans le document CH 531742 . Il en résulte que les chiffres défilent lentement dans un guichet. La lecture de l'information en est rendue difficile, plusieurs chiffres étant apparents pour la même information.When the information changes more frequently than once a day, the mechanism becomes more delicate in its operation, the energy available for each jump being significantly reduced. This problem can be solved by driving the disks continuously, as proposed in the document CH 531742 . As a result, the numbers slowly scroll through a window. The reading of the information is made difficult, several figures being apparent for the same information.

On connaît également le document WO 02/093273 , dans lequel l'information complémentaire est entraînée par une deuxième source d'énergie, indépendante de celle utilisée pour entraîner le rouage de finissage. Toutefois, le mécanisme proposé ne permet pas de stabiliser de manière suffisante l'entraînement du rouage d'affichage de la fonction complémentaire, particulièrement par rapport à l'énergie apportée par la deuxième source d'énergie.The document is also known WO 02/093273 in which the complementary information is driven by a second energy source, independent of that used to drive the finishing gear. However, the proposed mechanism does not sufficiently stabilize the drive train display of the complementary function, particularly with respect to the energy provided by the second energy source.

Le but de la présente invention est d'assurer un entraînement optimal du ou des disques, même de grande dimension et sans pour autant affecter la bonne marche de la montre.The object of the present invention is to ensure optimum drive or discs, even large and without affecting the smooth running of the watch.

A cet effet, le dispositif selon l'invention présente les caractéristiques énoncées dans la revendication 1.For this purpose, the device according to the invention has the features set forth in claim 1.

Ainsi, pratiquement aucune énergie n'est prélevée sur le rouage de finissage, même avec des disques de grand diamètre. Dans une montre mécanique, cela permet d'éviter que l'amplitude du balancier ne soit réduite par l'entraînement du disque. Dans une montre à quartz, l'énergie à délivrer par le moteur ne subit pas de fluctuation, ce qui permet d'augmenter son autonomie sans affecter son fonctionnement.Thus, virtually no energy is taken from the finishing gear, even with large diameter discs. In a mechanical watch, this prevents the amplitude of the pendulum is reduced by the drive of the disc. In a quartz watch, the energy to be delivered by the engine does not fluctuate, which increases its autonomy without affecting its operation.

De manière avantageuse, la deuxième source d'énergie est mécanique, à l'instar d'un barillet. Le dispositif selon l'invention comporte, en outre des moyens d'armage de cette source d'énergie.Advantageously, the second energy source is mechanical, like a barrel. The device according to the invention further comprises means for arming this source of energy.

Un tel dispositif permet d'équiper un mouvement de montre de type chronographe et comprenant:

  • un rouage de chronographe dont un mobile effectue un tour par minute et agencé pour porter des moyens d'affichage des secondes du temps chronométré, ainsi que
  • un embrayage agencé pour relier ou non le rouage de chronographe audit train d'engrenages et pour commander le départ et l'arrêt de la mesure d'un temps chronométré.
Such a device makes it possible to equip a watch movement of the chronograph type and comprising:
  • a chronograph wheel including a mobile performs one revolution per minute and arranged to wear display means seconds timed time, as well as
  • a clutch arranged to connect or not the chronograph gear to said gear train and to control the start and stop of the measurement of a timed time.

Le dispositif comporte des moyens d'entraînement pilotés par le rouage de chronographe et commandant l'entraînement du rouage d'affichage par le barillet.The device comprises drive means driven by the chronograph wheel and controlling the driving of the display train by the barrel.

Dans ce dispositif, le rouage d'affichage est agencé de manière à ce que le disque assure l'affichage de temps chronométrés supérieurs ou égaux à la minute.In this device, the display gear is arranged so that the disc ensures the display of timed times greater than or equal to one minute.

Un tel dispositif peut comporter plusieurs disques d'affichage et plusieurs barillets, chaque barillet entraînant un disque.Such a device may comprise several display disks and several barrels, each barrel driving a disk.

Afin d'assurer un entraînement régulier, le dispositif selon l'invention comporte:

  • un système de régulation, agencé pour stabiliser le mouvement de rotation dudit rouage, et
  • un mécanisme de déclenchement commandé au moins médiatement par le train d'engrenages de finissage et commandant l'entraînement du disque par le barillet, par l'intermédiaire du rouage d'affichage.
In order to ensure regular training, the device according to the invention comprises:
  • a control system, arranged to stabilize the rotational movement of said cog, and
  • a triggering mechanism controlled at least mediately by the finishing gear train and controlling the driving of the disc by the barrel, through the display gear.

Le système de régulation comprend avantageusement un volant d'inertie ainsi qu'une came munie d'un organe de blocage et tournant en synchronisme avec le volant. Le mécanisme de déclenchement comprend un levier agencé de manière à pouvoir occuper :

  • une première position dans laquelle il coopère avec l'organe de blocage pour immobiliser le système de régulation,
  • une deuxième position dans laquelle il libère la came et laisse tourner le système de régulation, et
  • une troisième position dans laquelle il vient en appui contre la came jusqu'à ce qu'il coopère à nouveau avec l'organe de blocage.
The control system advantageously comprises an inertia flywheel and a cam provided with a locking member and rotating in synchronism with the steering wheel. The trigger mechanism comprises a lever arranged so as to occupy:
  • a first position in which it cooperates with the locking member to immobilize the regulation system,
  • a second position in which it releases the cam and lets the control system run, and
  • a third position in which it bears against the cam until it cooperates again with the locking member.

Dans de tels dispositifs, la mise à zéro des disques par des marteaux, comme cela se fait fréquemment dans les chronographes, peut impliquer une pression exagérée. C'est pourquoi, de manière avantageuse, le dispositif selon l'invention comporte, avantageusement :

  • un mécanisme de mise à zéro comprenant un organe de positionnement,
  • un repère disposé sur le mobile du rouage d'affichage portant le disque et coopérant avec l'organe de positionnement pour assurer le positionnement du disque, et
  • des moyens de commande agencés de manière à ce que, lorsque le mécanisme de mise à zéro est activé, la source d'énergie mécanique entraîne le mobile du rouage d'affichage jusqu'à ce que le repère coopère avec l'organe de positionnement pour positionner le disque.
In such devices, zeroing the discs by hammers, as is frequently done in chronographs, may involve undue pressure. That is why, advantageously, the device according to the invention comprises, advantageously:
  • a zeroing mechanism comprising a positioning member,
  • a mark arranged on the mobile of the display gear carrying the disc and cooperating with the positioning member to ensure the positioning of the disc, and
  • control means arranged so that, when the zeroing mechanism is activated, the source of mechanical energy drives the mobile of the display train until the mark cooperates with the positioning member for position the disc.

De la sorte, la mise à zéro peut se faire sans effort pour l'utilisateur, même avec un, voire des disques, de grand diamètre.In this way, zeroing can be done without effort for the user, even with one or even disks, large diameter.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel:

  • la figure 1 représente une montre de type chronographe et munie d'un dispositif d'affichage à disques de temps chronométrés ;
  • les figures 2 à 4 illustrent les mécanismes que comporte le dispositif d'affichage et permettant l'entraînement des disques équipant la montre de la figure 1 ;
  • les figures 5a et 5b montrent la cinématique assurant le remontage des barillets que comporte cette montre ; et
  • la figure 6 se rapporte au mécanisme assurant la commande du départ et de l'arrêt d'une mesure, ainsi que la mise à zéro du mécanisme d'affichage par disques.
Other advantages and features of the invention will emerge from the description which follows, given with reference to the appended drawing, in which:
  • the figure 1 represents a chronograph type watch and provided with a timed disks display device;
  • the Figures 2 to 4 illustrate the mechanisms that comprise the display device and allowing the training of the discs equipping the watch of the figure 1 ;
  • the Figures 5a and 5b show the kinematics ensuring the winding of the barrels that includes this watch; and
  • the figure 6 refers to the mechanism for controlling the start and stop of a measurement, as well as the zeroing of the disk display mechanism.

La montre représentée à la figure 1 comporte une boîte 10 définissant un logement à l'intérieur duquel se trouve un mouvement. Ce dernier est équipé d'un mécanisme de chronographe, bien connu en soi, ainsi que d'un dispositif d'affichage selon l'invention qui sera décrit de manière plus détaillée ci-après.The watch represented at figure 1 comprises a box 10 defining a housing within which there is a movement. The latter is equipped with a chronograph mechanism, well known per se, and a display device according to the invention which will be described in more detail below.

Le mouvement porte un cadran 12, des aiguilles des heures 14, des minutes 16, des secondes 18, de réserve de marche 20, ainsi que des secondes de temps chronométré 22. Le cadran 12 est muni de trois guichets au travers desquels apparaissent des disques 24, 26 et 28, affichant respectivement les heures, les dizaines de minutes et les unités de minutes de temps chronométré, assurant donc la fonction d'affichage du dispositif selon l'invention.The movement carries a dial 12, hour hands 14, minutes 16, seconds 18, power reserve 20, as well as timed seconds 22. The dial 12 is provided with three wickets through of which discs 24, 26 and 28 appear, respectively displaying hours, tens of minutes and units of minutes of timed time, thus providing the display function of the device according to the invention.

Une couronne de remontoir et de mise à l'heure 30 et des poussoirs 31 et 32 sont disposés de manière classique, sur la tranche de la boîte 10. La couronne 30 permet de fournir l'énergie mécanique nécessaire au fonctionnement du mouvement, par remontage d'un ressort de barillet, comme cela sera expliqué plus loin. Les poussoirs 31 et 32 commandent respectivement le départ et l'arrêt, et la mise à zéro du mécanisme de chronographe et de son dispositif d'affichage.A winding crown and setting time 30 and pushers 31 and 32 are arranged in a conventional manner, on the edge of the box 10. The ring 30 provides the mechanical energy necessary for the operation of the movement, by winding of a mainspring, as will be explained later. The pushers 31 and 32 respectively control the start and stop, and the zeroing of the chronograph mechanism and its display device.

La base du mouvement est formée d'un calibre chronographe tel que celui commercialisé par la maison ETA SA (Suisse) sous la référence 7750. Ce mouvement comporte une platine 33, visible sur la figure 2, un rouage de chronographe et un mécanisme de départ et d'arrêt, qui ne sont que très partiellement visibles au dessin, étant bien connus de l'homme du métier. Il comprend, en outre, un barillet, un rouage de finissage, un échappement et un balancier. De manière classique, le barillet apporte l'énergie au rouage de finissage, qui la délivre à l'échappement, lequel transforme le mouvement rotatif du rouage en mouvement alternatif, pour alimenter le balancier.The base of the movement is formed of a chronograph caliber such as that marketed by ETA SA (Switzerland) under the reference 7750. This movement comprises a plate 33, visible on the figure 2 , a chronograph wheel and a start and stop mechanism, which are only partially visible in the drawing, being well known to those skilled in the art. It comprises, in addition, a barrel, a finishing gear, an escapement and a pendulum. Conventionally, the barrel brings energy to the finishing train, which delivers it to the exhaust, which transforms the rotary movement of the gear in reciprocating movement, to power the balance.

Le rouage de chronographe comprend une roue des secondes de temps chronométré, qui porte l'aiguille des secondes de temps chronométré 22, et une roue des minutes de temps chronométré 34 entraînée de manière classique par la roue des secondes de temps chronométré, à raison de un pas toutes les minutes. Dans les chronographes à affichage par aiguilles, la roue des minutes 34 porte l'aiguille des minutes de temps chronométré.The chronograph wheel includes a second wheel of timed time, which carries the seconds hand of timed time 22, and a minute wheel of timed time 34 driven in a conventional manner by the seconds wheel of timed time, at the rate of one step every minute. In the chronographs with needle display, the minute wheel 34 carries the minute hand of time timed.

Le dispositif d'affichage selon l'invention comporte disposé, sur la platine 33, des moyens d'entraînement 36 du disque des unités 28, plus particulièrement illustré sur la figure 2. Ces moyens d'entraînement 36 comprennent un mécanisme de déclenchement 38 commandé par la roue 34, un système de régulation 40 libéré par le mécanisme de déclenchement 38, un rouage d'entraînement de l'affichage 42 du disque des unités 28 et une source d'énergie formée d'un barillet 43 fournissant son énergie à la fois au système de régulation 40 et au rouage 42.The display device according to the invention comprises, on the plate 33, drive means 36 of the disk of the units 28, more particularly illustrated on FIG. figure 2 . These drive means 36 comprise a triggering mechanism 38 controlled by the wheel 34, a control system. control 40 released by the triggering mechanism 38, a drive train of the display 42 of the disk of the units 28 and a power source formed of a cylinder 43 supplying its energy to both the control system 40 and the gears 42.

De manière plus précise, le mécanisme de déclenchement 38 est formé de deux leviers 44 et 46 montés pivotants sur la platine 33 et d'un ressort 48. Le levier 44 comporte deux bras 44a et 44b disposés de part et d'autre de son point de pivotement, le bras 44a étant muni, à son extrémité libre, d'un doigt 44c disposé de manière à être en prise avec la denture de la roue 34.More specifically, the trigger mechanism 38 is formed of two levers 44 and 46 pivotally mounted on the plate 33 and a spring 48. The lever 44 has two arms 44a and 44b disposed on either side of its point of pivoting, the arm 44a being provided, at its free end, with a finger 44c arranged to be in engagement with the toothing of the wheel 34.

Le levier 46 est muni de deux levées 46a et 46b destinées à coopérer avec le système de régulation 40, comme cela sera expliqué plus loin, et un plot 46c coopérant avec le levier 44. Il est maintenu en position de repos, les levées 46a et 46b retenant le système de régulation 40, sous l'effet du ressort 48. Les leviers 44 et 46 sont agencés et coopèrent l'un avec l'autre de manière telle que lorsque la roue 34 soulève le levier 44, le bras 44b applique contre le plot 46c une force antagoniste à celle du ressort 48. Cela fait pivoter le levier 46, ce qui provoque le dégagement des levées 46a et 46b du système de régulation 40.The lever 46 is provided with two lifts 46a and 46b intended to cooperate with the regulation system 40, as will be explained below, and a stud 46c cooperating with the lever 44. It is maintained in the rest position, the lifts 46a and 46b retaining the regulation system 40, under the effect of the spring 48. The levers 44 and 46 are arranged and cooperate with each other such that when the wheel 34 raises the lever 44, the arm 44b applies against the stud 46c a force opposing that of the spring 48. This rotates the lever 46, which causes the release of the lifts 46a and 46b of the control system 40.

Le système de régulation 40 comprend un train d'engrenages multiplicateur de la vitesse comportant deux mobiles 50 et 52, et un volant d'inertie 54. Le mobile 50 comprend un pignon 50a, qui engrène avec le barillet 43, et une roue 50b entraînant le mobile 52 par son pignon non visible au dessin. Ce mobile comporte, en outre une roue 52b et une came 52c. La roue 52b engrène avec un pignon non visible au dessin que comporte le volant 54. La came 52c se présente sous forme d'une rondelle munie d'une encoche 52d. Elle coopère avec la levée 46a du levier 46, qui est maintenue par le ressort 48 en appui contre le pourtour de la came ou engagée dans l'encoche 52d, selon la position du mobile 52.The control system 40 comprises a speed-increasing gear train comprising two mobiles 50 and 52, and a flywheel 54. The mobile 50 comprises a pinion 50a, which meshes with the barrel 43, and a driving wheel 50b. mobile 52 by its pinion not visible in the drawing. This mobile further comprises a wheel 52b and a cam 52c. The wheel 52b meshes with a pinion not visible in the drawing that includes the flywheel 54. The cam 52c is in the form of a washer provided with a notch 52d. It cooperates with the lift 46a of the lever 46, which is held by the spring 48 bearing against the periphery of the cam or engaged in the notch 52d, according to the position of the mobile 52.

Le volant 54 est doté de deux bras 54a portant chacun une aile 54b, ainsi que trois doigts de retenue 54c, disposés radialement et agencés pour coopérer avec la levée 46b. Les ailes 54b comportent chacune une portion élastique 54d en arc de cercle concentrique à l'axe de rotation du volant, solidaire de l'un des bras 54a par l'une de ses extrémités, et s'étendant sur un angle d'environ 90°. Les portions élastiques 54d sont munies, à leur autre extrémité, d'une masse d'inertie et de freinage 54e, destinée à coopérer avec un tambour 56 entourant le volant 54 et solidaire de la platine 33. Plus précisément, lorsque le volant 54 tourne, les portions élastiques 54d des ailes 54b se déforment élastiquement sous l'effet de leur masse d'inertie 54e, lesquelles viennent frotter contre le tambour 56.The steering wheel 54 is provided with two arms 54a each carrying a wing 54b, and three retaining fingers 54c, arranged radially and arranged to cooperate. with lifting 46b. The wings 54b each comprise an elastic portion 54d in an arc of a circle concentric with the axis of rotation of the wheel, secured to one of the arms 54a by one of its ends, and extending over an angle of about 90.degree. °. The elastic portions 54d are provided at their other end with a mass of inertia and braking 54e, intended to cooperate with a drum 56 surrounding the flywheel 54 and secured to the plate 33. More precisely, when the steering wheel 54 rotates , the elastic portions 54d of the wings 54b elastically deform under the effect of their mass of inertia 54e, which rub against the drum 56.

Le rouage d'entraînement de l'affichage 42 comporte un mobile 58, en prise avec la denture du barillet 43 par son pignon, un renvoi 60, entraîné par la roue du mobile 58, et entraînant une roue 62 des unités. Cette dernière porte le disque des unités 28, ainsi qu'une came de déclenchement 64, laquelle est munie d'une goupille 64a et d'un doigt 64b, dont les fonctions seront précisées plus loin.The drive train of the display 42 comprises a mobile 58, engaged with the toothing of the cylinder 43 by its pinion, a return 60, driven by the wheel of the mobile 58, and driving a wheel 62 units. The latter carries the disk of the units 28, and a trigger cam 64, which is provided with a pin 64a and a finger 64b, whose functions will be specified later.

Les mobiles du système de régulation 40 et du rouage 42 sont nombrés de manière à ce que la roue 62 tourne de 36° pour un tour du mobile 52.The mobiles of the regulation system 40 and the gear 42 are numbered so that the wheel 62 rotates 36 ° for one revolution of the mobile 52.

Chaque fois que la roue 34 soulève le doigt 44c et entraîne en conséquence les leviers 44 et 46, les levées 46a et 46b libèrent respectivement la came 52c et les doigts 54c. De la sorte, le système de régulation 40 se met à tourner à une vitesse régulée par la friction des masses 54e sur le tambour 56. Simultanément, le rouage d'entraînement 42 tourne et fait avancer la roue 62 de 36° et avec elle le disque des unités 28 d'un pas, l'affichage visible au travers du guichet étant incrémenté d'une unité.Whenever the wheel 34 lifts the finger 44c and consequently drives the levers 44 and 46, the lifts 46a and 46b respectively release the cam 52c and the fingers 54c. In this way, the control system 40 starts to rotate at a speed regulated by the friction of the masses 54e on the drum 56. Simultaneously, the drive train 42 rotates and advances the wheel 62 36 ° and with it the disk 28 units of a step, the visible display through the window being incremented by one unit.

Dès que la roue 34 libère le doigt 44c, le levier 46 retombe sous l'effet du ressort 38. La levée 46a vient alors en appui contre la came 52c, sans en entraver le mouvement de manière significative. La came continue donc à tourner jusqu'à ce que la levée 46a retombe dans l'encoche 52d. La levée 46b vient alors bloquer le volant en coopérant avec l'un des doigts 54c.As soon as the wheel 34 releases the finger 44c, the lever 46 falls under the effect of the spring 38. The lift 46a then bears against the cam 52c, without hindering the movement significantly. The cam continues to rotate until the lift 46a falls into the notch 52d. The lift 46b then comes to block the steering wheel by cooperating with one of the fingers 54c.

Une telle structure permet d'expliquer de manière simple le principe de fonctionnement du dispositif, les fonctions de régulation et d'entraînement étant séparées. Il serait aussi possible de simplifier la structure en combinant ces fonctions, par engrènement du pignon du mobile 52 avec une roue que porterait le mobile 58, le renvoi 60 ou la roue 62.Such a structure makes it possible to explain in a simple manner the operating principle of the device, the regulation and drive functions being separated. It would also be possible to simplify the structure by combining these functions, by meshing the pinion of the mobile 52 with a wheel that would carry the mobile 58, the reference 60 or the wheel 62.

La figure 3 représente des moyens d'entraînement 136 du disque des dizaines 26. Ils sont, pour l'essentiel, similaires aux moyens d'entraînement 36 du disque des unités, les pièces constitutives portant la même référence que celles des moyens d'entraînement 36, munies d'un « 1 » pour chiffre des centaines.The figure 3 represents drive means 136 of the tens disk 26. They are essentially similar to the driving means 36 of the disk of the units, the constituent parts bearing the same reference as those of the drive means 36, provided with a "1" for hundreds.

Le fonctionnement des moyens d'entraînement 136 est, bien sûr, également comparable à celui des moyens d'entraînement 36.The operation of the drive means 136 is, of course, also comparable to that of the drive means 36.

Chaque fois que le disque des unités 28 a fait un tour, passant de 9 à 0, et, avec lui, la came 64, le doigt 64b, visible seulement sur la figure 2, soulève le doigt 144c du levier 144. Le levier 144 soulève le plot 146c et fait pivoter le levier 146, armant le ressort 148, alors que les levées 146a et 146b libèrent le système de régulation 140. Le barillet 143 n'est alors plus retenu. Il entraîne le volant 154 dont les masses 154e viennent en contact avec le tambour 156, régulant le mouvement du barillet 143 et du rouage d'entraînement 142 du disque des dizaines de minutes, dont la roue 162 porte le disque des dizaines 26.Whenever the disk of the units 28 has made a turn, passing from 9 to 0, and with it, the cam 64, the finger 64b, visible only on the figure 2 , lifts the finger 144c of the lever 144. The lever 144 raises the stud 146c and pivots the lever 146, cocking the spring 148, while the lifts 146a and 146b release the regulation system 140. The barrel 143 is then no longer retained. It drives the flywheel 154 whose masses 154e come into contact with the drum 156, regulating the movement of the barrel 143 and the drive train 142 of the disc tens of minutes, whose wheel 162 carries the tens disk 26.

Dès que la came 64 a terminé son déplacement, elle libère les leviers 144 et 146, de telle sorte que le ressort 148 amène la levée 146a en appui contre la came 152c. Lorsque cette dernière a effectué un tour complet, la levée 146a retombe dans l'encoche 152d de la came 152 et bloque son mouvement. Le disque des dizaines 26 a ainsi sauté de un pas.Once the cam 64 has completed its movement, it releases the levers 144 and 146, so that the spring 148 brings the lift 146a in abutment against the cam 152c. When the latter has completed a complete revolution, the lift 146a falls back into the notch 152d of the cam 152 and blocks its movement. The tens disk 26 thus jumped a step.

Les mobiles du rouage d'entraînement 142 et du système de régulation 140 sont nombrés de manière à ce que le disque des dizaines 26 tourne de 60° à chaque pas, ce disque portant les chiffres de 0 à 5.The mobiles of the drive train 142 and the regulation system 140 are numbered so that the tens disk 26 rotates 60 ° at each step, this disk bearing the numbers from 0 to 5.

La roue 162 est, en outre, munie d'une came 164, comportant une goupille 164a et un doigt 164b agencé pour commander le saut du disque des heures 24, comme cela sera expliqué plus loin.The wheel 162 is further provided with a cam 164, having a pin 164a and a finger 164b arranged to control the jump of the disk hours 24, as will be explained later.

L'entraînement du disque des heures 24 se fait par des moyens d'entraînement 236, illustrés sur la figure 4 et similaires aux moyens d'entraînement 36 et 136, les pièces constitutives portant la même référence que celles des moyens d'entraînement 36 et 136, munies d'un « 2 » pour chiffre des centaines.The training of the hours 24 disk is done by drive means 236, illustrated in FIG. figure 4 and similar to the drive means 36 and 136, the component parts bearing the same reference as those of the drive means 36 and 136, provided with a "2" for a number of hundreds.

Le fonctionnement des moyens d'entraînement 236 est, bien sûr, également comparable à celui des moyens d'entraînement 36. Dans ce cas toutefois, le nombre de mobiles que comportent le système de régulation 240 et le rouage d'entraînement 242 est plus élevé. Cela ne modifie en rien son fonctionnement.The operation of the drive means 236 is, of course, also comparable to that of the drive means 36. In this case, however, the number of mobiles that comprise the control system 240 and the drive train 242 is higher. . This does not change its operation.

Ainsi, chaque fois que le disque des dizaines de minutes 26 passe de 5 à 0, le doigt 164b de la came 164 (figure 3) soulève le doigt 244c, ce qui fait basculer le levier 244 et, par l'intermédiaire du plot 246c, le levier 246, armant ainsi le ressort de rappel 248. Les levées 246a et 246b libèrent le système de régulation 240, de telle sorte que le barillet 243 peut tourner, et avec lui le rouage d'entraînement 242 du disque des heures. Le rouage d'entraînement 242 comprend un mobile 260 disposé concentriquement aux roues 62 et 162, et muni d'une goupille 260a dont la fonction sera précisée plus loin.Thus, each time the disk tens of minutes 26 passes from 5 to 0, the finger 164b of the cam 164 ( figure 3 ) raises the finger 244c, which causes the lever 244 to rock and, via the stud 246c, the lever 246, thus arming the return spring 248. The lifts 246a and 246b release the regulation system 240, so that that the barrel 243 can rotate, and with it the drive train 242 hours disk. The drive train 242 comprises a mobile 260 arranged concentrically with the wheels 62 and 162, and provided with a pin 260a whose function will be specified later.

La roue 262, qui porte le disque 24, se présente sous forme d'une bague entourant de manière décentrée le centre du mouvement, et maintenue en place au moyen d'une plaque 263, fixée à la platine 33 au moyen de vis non représentées au dessin, et percée d'un trou au travers duquel passe l'axe de la roue des secondes de temps chronométré ainsi que les mobiles portant les aiguilles des heures 14 et des minutes 16.The wheel 262, which carries the disc 24, is in the form of a ring decenterally surrounding the center of the movement, and held in place by means of a plate 263, fixed to the plate 33 by means of screws not shown. to the drawing, and pierced with a hole through which passes the axis of the seconds wheel of timed time as well as the mobiles carrying the hands of hours 14 and minutes 16.

Grâce aux moyens d'entraînement 36, 136 et 236, l'entraînement des disques 24, 26 et 28 se fait sans augmenter la charge du barillet assurant la rotation du rouage de finissage. Ainsi, l'amplitude du balancier n'est pas affectée par les sauts des disques d'affichage.With the drive means 36, 136 and 236, the driving of the discs 24, 26 and 28 is done without increasing the load of the barrel ensuring the rotation the finishing gear. Thus, the amplitude of the pendulum is not affected by the jumps of the display disks.

Les figures 5a et 5b montrent les faces opposées d'un mécanisme de remontoir 65 des ressorts de barillet que comporte le mouvement. En plus de l'armage des barillets 43, 143 et 243, il remonte également le barillet 66 destiné à entraîner le rouage de finissage et mentionné plus haut. Ces barillets comportent chacun un tambour identifié par la lettre a, un arbre b, un ressort non représenté au dessin et dont une extrémité est fixée à l'arbre b, l'autre coopérant avec la paroi intérieure du tambour a par l'intermédiaire d'une bride glissante. Une roue à rochet, identifiée par la lettre c, est fixée à l'arbre b.The Figures 5a and 5b show the opposite faces of a winding mechanism 65 of the barrel springs that the movement comprises. In addition to the winding of the barrels 43, 143 and 243, it also raises the barrel 66 for driving the gear train and mentioned above. These barrels each comprise a drum identified by the letter a, b a shaft, a spring not shown in the drawing and whose one end is fixed to the shaft b, and the other cooperating with the inner wall of the drum by means of a slippery flange. A ratchet wheel, identified by the letter c , is attached to the shaft b .

On relèvera que les barillets 143 et 243, respectivement visibles sur les figures 5b et 5a, sont coaxiaux. Leurs arbres 143b et 243b sont agencés de manière à être solidaires en rotation, et entraînés ensemble par la roue à rochet 143c.It will be noted that the barrels 143 and 243, respectively visible on the Figures 5b and 5a , are coaxial. Their shafts 143b and 243b are arranged to be integral in rotation, and driven together by the ratchet wheel 143c.

Ces figures montrent également la couronne de remontoir et de mise à l'heure 30. Celle-ci est solidaire d'une tige 67 assurant la liaison entre l'extérieur et l'intérieur de la boîte 10. Un pignon de remontoir 68 et un pignon coulant 70 sont montés pivotant sur la tige 67, reliés cinématiquement l'un à l'autre par une denture Breguet, et coopérant avec un mécanisme de remontoir et de mise à l'heure, comme il est d'usage dans ce type de mouvements, mais qui n'a pas été représenté pour éviter de surcharger le dessin.These figures also show the winding crown and time setting 30. It is secured to a rod 67 providing the connection between the outside and the inside of the box 10. A winding pinion 68 and a sliding pinion 70 are pivotally mounted on the rod 67, kinematically connected to one another by a Breguet toothing, and cooperating with a winding mechanism and time setting, as is customary in this type of movements, but which has not been shown to avoid overloading the drawing.

Une roue de couronne 72, montée libre en rotation sur un pont non représenté au dessin, engrène avec le pignon de remontoir 68 ainsi qu'avec la roue à rochet 66c du barillet 66, visible sur la figure 5b.A crown wheel 72, mounted free to rotate on a bridge not shown in the drawing, meshes with the winding pinion 68 and with the ratchet wheel 66c of the barrel 66, visible on the figure 5b .

Avec cette configuration, et pour remonter le barillet 66, il suffit de tourner la couronne 30, solidaire de la tige 67, lorsqu'elle se trouve en position enfoncée. La tige 67 entraîne le pignon coulant 70 et par lui le pignon de remontoir 68, lequel est relié à la roue de couronne 72 qui arme le ressort du barillet 66 par l'intermédiaire de la roue à rochet 66c et de l'arbre 66b. L'entraînement ne se fait que dans un sens, le débrayage s'effectuant entre le pignon coulant 70 et le pignon de remontoir 68, grâce à la denture Breguet.With this configuration, and to raise the barrel 66, simply turn the ring 30, secured to the rod 67, when in the depressed position. The rod 67 drives the sliding pinion 70 and by it the winding pinion 68, which is connected to the crown wheel 72 which arms the spring of the barrel 66 by means of the ratchet wheel 66c and the shaft 66b. The drive is only in one direction, the clutch taking place between the sliding pinion 70 and the winding pinion 68, thanks to the Breguet toothing.

Un train de renvois 74 relie entre elles les roues à rochet. Plus précisément, un premier renvoi 74a est monté sur un carré 66d que comporte l'arbre 66b. Il entraîne un deuxième renvoi 74b en prise avec la roue à rochet 43c. Cette dernière est reliée à la roue à rochet 143c, visible sur la figure 5b, par quatre renvois 74c à 74f, visibles sur la figure 5a.A train of referrals 74 interconnects the ratchet wheels. More specifically, a first reference 74a is mounted on a square 66d that includes the shaft 66b. It causes a second return 74b engaged with the ratchet wheel 43c. The latter is connected to the ratchet wheel 143c, visible on the figure 5b , by four references 74c to 74f, visible on the figure 5a .

Le nombre de renvois (pair ou impair) compris entre deux roues à rochet est fonction du sens de rotation dans lequel se fait l'armage du ressort.The number of returns (even or odd) between two ratchet wheels depends on the direction of rotation in which the spring is wound.

Il va de soi que, pour assurer le remontage de tous les barillets, leur roue à rochet coopère avec un cliquet, non représenté au dessin, et qui empêche le ressort contenu dans le tambour de se désarmer.It goes without saying that, to ensure the reassembly of all the barrels, their ratchet wheel cooperates with a pawl, not shown in the drawing, and which prevents the spring contained in the drum from disarming.

De la sorte, en tournant la couronne 30, on arme les quatre barillets 66, 43, 143 et 243. Ils peuvent, sans autre, être armés à fond, quel que soit leur état initial, du fait qu'ils sont tous équipés d'une bride glissante.In this way, by turning the crown 30, the four barrels 66, 43, 143 and 243 are armed. They can, without further, be fully armed, whatever their initial state, because they are all equipped with a slippery flange.

Le dispositif ainsi décrit permet d'entraîner chacun des disques de l'affichage du chronographe au moyen d'un barillet qui lui est propre. De la sorte, il n'est prélevé, sur le rouage de finissage, que l'énergie nécessaire à l'entraînement des roues des secondes et des minutes de temps chronométré et au déclenchement du dispositif.The device thus described makes it possible to drive each of the disks of the chronograph display by means of a barrel of its own. In this way, it is taken, on the work train, only the energy required to drive the wheels seconds and minutes of timed time and the triggering of the device.

Dans une variante qui n'a pas été représentée, il serait également possible d'assurer la fonction des barillets 143 et 243 par un seul barillet. Il suffirait de remplacer le renvoi 160 par une roue comportant deux secteurs dentés superposés, l'un destiné à entraîner le disque des dizaines de minutes, comportant le même nombre de dents que la roue 162, l'autre destiné à entraîner le disque des heures et comportant le dixième des dents de la roue 262. Dans ce cas, il serait nécessaire de prévoir des moyens de positionnement des disques 24 et 26, ainsi que des marteaux de remise à zéro, les roues portant les disques n'étant pas en prise permanente avec le rouage.In a variant that has not been shown, it would also be possible to ensure the function of the barrels 143 and 243 by a single barrel. It would suffice to replace the reference 160 by a wheel having two toothed sectors superimposed, one intended to drive the disk tens of minutes, having the same number of teeth as the wheel 162, the other intended to drive the disk hours and comprising the tenth of the teeth of the wheel 262. In this case, it would be necessary to provide means for positioning the discs 24 and 26, as well as reset hammers, the wheels carrying the discs not being engaged. permanent with the cog.

Du fait que le disque des heures 24 effectue neuf pas seulement et un tour au maximum, il est aussi possible de stocker l'énergie nécessaire à son entraînement autrement que dans un barillet, par exemple dans un ressort coopérant avec un colimaçon.Because the hour disk 24 performs nine steps and a maximum of one turn, it is also possible to store the energy required for its drive other than in a barrel, for example in a spring cooperating with a spiral.

Le dispositif d'affichage selon l'invention comporte, en outre, un mécanisme de mise à zéro des disques 24, 26 et 28, illustré partiellement sur la figure 6. Il est commandé par les poussoirs 31 et 32 représentés sur la figure 1. Il coopère avec un levier de commande 76, partie du mécanisme de chronographe, activé par le poussoir 31 et qui actionne un embrayage reliant, de manière classique, le rouage de finissage à la roue 34, par l'intermédiaire d'une roue des secondes de chronographe, non représentée au dessin.The display device according to the invention further comprises a mechanism for zeroing the discs 24, 26 and 28, partially illustrated on the figure 6 . It is controlled by the pushers 31 and 32 shown on the figure 1 . It cooperates with a control lever 76, part of the chronograph mechanism, activated by the pusher 31 and which actuates a clutch connecting, in a conventional manner, the work train to the wheel 34, via a wheel of seconds chronograph, not shown in the drawing.

De manière classique, une première pression sur le poussoir 31 fait démarrer la mesure et enclenche l'embrayage. Une deuxième pression arrête la mesure par débrayage.Conventionally, a first pressure on the pusher 31 starts the measurement and engages the clutch. A second press stops the measurement by disengaging.

Dès que le mécanisme de chronographe est enclenché, son rouage est mis en mouvement, la roue 34 étant entraînée à raison d'un pas par minute, engendrant les sauts de disques décrits en référence aux figures 2 à 4.As soon as the chronograph mechanism is engaged, its wheel is set in motion, the wheel 34 being driven at a rate of one step per minute, generating the disc jumps described with reference to the Figures 2 to 4 .

Après que la mesure a été faite, que le temps a été relevé, les disques peuvent être mis à zéro par une pression sur le poussoir 32, lequel commande des moyens de mise à zéro que comporte le mécanisme de chronographe. Ces moyens comprennent, de manière classique, un levier de mise à zéro 78 qui actionne un marteau assurant la mise à zéro de la roue des secondes de chronographe.After the measurement has been made, the time has been raised, the disks can be set to zero by pressing the pusher 32, which controls the reset means included in the chronograph mechanism. These means comprise, in a conventional manner, a zeroing lever 78 which actuates a hammer ensuring the zeroing of the chronograph second wheel.

Le mécanisme de mise à zéro du dispositif selon l'invention comprend :

  • un levier de commande 80,
  • une bascule de sautoir 82 munie d'un plot de sautoir 82a,
  • un organe de positionnement 84 des disques, doté de deux doigts 84a coopérant avec la bascule 82 et deux crochets de positionnement 84b superposés, dont la fonction sera précisée plus loin,
  • une bascule de déclenchement 86,
  • un levier 87 commandé par la bascule 86,
  • un ressort 88, coopérant avec la bascule 86, et
  • un sautoir 90, visible très partiellement sur la figure et coopérant avec le plot 82a pour positionner la bascule 82.
The zeroing mechanism of the device according to the invention comprises:
  • a control lever 80,
  • a jumper latch 82 provided with a jumper pad 82a,
  • a positioning member 84 of the disks, provided with two fingers 84a cooperating with the rocker 82 and two superposed positioning hooks 84b, the function of which will be specified below,
  • a trigger rocker 86,
  • a lever 87 controlled by the flip-flop 86,
  • a spring 88, cooperating with the rocker 86, and
  • a jumper 90, visible very partially in the figure and cooperating with the stud 82a to position the flip-flop 82.

Dans leur position de repos, les crochets 84b sont disposés de manière à ce qu'ils coopèrent avec les goupilles 64a, 164a et 260a, pour définir la position initiale des disques 24, 26 et 28, comme cela sera expliqué plus loin.In their rest position, the hooks 84b are arranged so that they cooperate with the pins 64a, 164a and 260a, to define the initial position of the discs 24, 26 and 28, as will be explained later.

Lors du démarrage d'une mesure par une pression sur le poussoir 31, le levier de commande 76 fait pivoter la bascule 82 qui entraîne l'organe de positionnement 84 par l'intermédiaire des doigts 84a, jusque dans la position représentée sur la figure 6. La bascule 82 est maintenue dans sa nouvelle position par le sautoir 90. De la sorte, les crochets de positionnement 84b s'écartent des goupilles. Les disques 24, 26 et 28 ne sont plus retenus et peuvent donc sans autre être entraînés en rotation, ce que fait la roue 34 à chacun de ses tours pour le disque 28, les autres disques étant incrémentés comme indiqués plus haut.When starting a measurement by pressing on the pusher 31, the control lever 76 rotates the latch 82 which drives the positioning member 84 via the fingers 84a to the position shown in FIG. figure 6 . The latch 82 is held in its new position by the jumper 90. In this way, the positioning hooks 84b deviate from the pins. The discs 24, 26 and 28 are no longer retained and can therefore be rotated, which is the wheel 34 at each of its turns for the disc 28, the other discs being incremented as indicated above.

Une nouvelle pression sur le poussoir 31 a pour effet de déplacer l'embrayage, de telle sorte que le rouage de chronographe n'est plus en prise avec le train d'engrenages de finissage Ainsi, la mesure est interrompue, l'affichage du temps chronométré étant fixe. L'information peut donc être lue. On relèvera que cette nouvelle pression n'agit pas sur l'organe 84, puisqu'il est maintenu en position enfoncée par le sautoir 90.A new pressure on the pusher 31 has the effect of moving the clutch, so that the chronograph train is no longer in contact with the finishing gear train. Thus, the measurement is interrupted, the display of the time timed being fixed. The information can therefore be read. It will be noted that this new pressure does not act on the member 84, since it is held in the depressed position by the jumper 90.

Pour remettre les disques à zéro, on exerce une pression sur le poussoir 32 lequel actionne le levier de mise à zéro 78 qui commande, de manière classique, la mise à zéro du mécanisme de chronographe. Le levier 78 fait pivoter le levier de commande 80 qui agit simultanément sur les bascules 82 et 86.To reset the disks, pressure is exerted on the pusher 32 which actuates the zeroing lever 78 which controls, in a conventional manner, the zeroing of the chronograph mechanism. The lever 78 rotates the control lever 80 which acts simultaneously on the latches 82 and 86.

La bascule 86 soulève les leviers 44, 144 et 244, les deux derniers par l'intermédiaire du levier 87. Les leviers 44, 144 et 244 actionnent respectivement les leviers 46, 146 et 246, de telle sorte que les levées qu'ils comportent libèrent les systèmes de régulation 40, 140 et 240, respectivement visibles sur les figures 2, 3 et 4. En conséquence, les rouages d'entraînement 42, 142 et 242 peuvent tourner sous l'effet des ressorts que comportent les barillets 43, 143 et 243.The rocker 86 raises the levers 44, 144 and 244, the last two via the lever 87. The levers 44, 144 and 244 actuate respectively the levers 46, 146 and 246, so that the lifts they include release the control systems 40, 140 and 240, respectively visible on the figures 2 , 3 and 4 . As a result, the drive wheels 42, 142 and 242 can rotate under the effect of the springs that comprise the barrels 43, 143 and 243.

Simultanément, la bascule 82 entraîne, par l'intermédiaire de l'un des doigts 84a, l'organe de positionnement 84, de telle sorte que les crochets 84b se trouvent à nouveau sur le chemin des goupilles 64a, 164a et 260a. L'extrémité de la bascule 82 voisine du levier 86 s'engage dans un cran que comporte ce dernier, masqué par la roue 62, de telle sorte qu'ils restent engagés l'un avec l'autre, maintenant en outre l'organe de positionnement 84 en position de blocage des disques. Les goupilles 64a, 164a et 260a sont, bien entendu, disposées de manière à ce qu'elles coopèrent avec les crochets 84b et qu'elles arrêtent les disques dans une position telle que les chiffres « 0 » apparaissent dans les guichets.Simultaneously, the rocker 82 drives, via one of the fingers 84a, the positioning member 84, so that the hooks 84b are found again in the path of the pins 64a, 164a and 260a. The end of the flip-flop 82 next to the lever 86 engages in a notch which the latter comprises, masked by the wheel 62, so that they remain engaged with each other, and in addition the organ positioning 84 in the blocking position of the disks. The pins 64a, 164a and 260a are, of course, arranged so that they cooperate with the hooks 84b and stop the discs in a position such that the numbers "0" appear in the windows.

Pour faire redémarrer une mesure, il suffit de presser sur le poussoir 31. Le levier 76 entraîne tout d'abord la bascule 82, qui libère le levier 86. Les leviers 46, 146 et 246 ne sont alors plus retenus et basculent respectivement sous l'effet des ressorts 48, 148 et 248. Les levées qu'ils comportent tombent les unes dans les découpes 52d, 152d et 252d des cames 52c, 152c et 252c, alors que les autres se placent en regard des doigts 54c, 154c et 254c avec lesquelles elles coopèrent. Par ailleurs, l'embrayage que comporte le mécanisme de chronographe relie le rouage de finissage à la roue des secondes de temps chronométré. Cette roue de secondes entraîne la roue 34 qui commande les moyens d'entraînement 36 du disque des unités 28, comme cela a été décrit plus haut. Une nouvelle mesure recommence alors.To restart a measurement, it suffices to press on the push-button 31. The lever 76 firstly drives the rocker 82, which releases the lever 86. The levers 46, 146 and 246 are then no longer retained and tilt respectively under the control. The effect of the springs 48, 148 and 248. The lifts they comprise fall into the cutouts 52d, 152d and 252d of the cams 52c, 152c and 252c, while the others are placed opposite the fingers 54c, 154c and 254c with whom they cooperate. In addition, the clutch in the chronograph mechanism connects the finishing gear to the second wheel of time timed. This seconds wheel drives the wheel 34 which controls the driving means 36 of the disk of the units 28, as described above. A new measurement then starts again.

On relèvera que, dans le mécanisme décrit, les leviers 44, 46, 144, 146, 244 et 246 présentent des découpes qui permettent de les équilibrer et de les alléger. De la sorte, les forces à appliquer pour faire fonctionner le mécanisme, et la sensibilité aux chocs sont considérablement réduites.It will be noted that, in the mechanism described, the levers 44, 46, 144, 146, 244 and 246 have cutouts that allow them to be balanced and lightened. In this way, the forces to be applied to operate the mechanism, and the sensitivity to impacts are greatly reduced.

Le dispositif d'affichage décrit ci-dessus est associé à un mécanisme de chronographe. Le même dispositif pourrait facilement être appliqué à un mécanisme de compte à rebours, par exemple, du type affichant un temps décroissant, ou destiné au départ des régates.The display device described above is associated with a chronograph mechanism. The same device could easily be applied to a countdown mechanism, for example, of the type displaying a decreasing time, or intended at the start of the regattas.

Le remontage des barillets est effectué en une seule opération. Il est aussi imaginable de munir le mouvement d'une deuxième couronne de remontoir, le barillet entraînant le rouage de finissage et ceux entraînant l'affichage du temps chronométré étant armés de manière indépendante, l'un par la couronne disposée à 3 heures, les autres par une couronne qui peut se trouver à 9 heures par exemple. Il est également possible d'imaginer une montre à quartz munie d'un mécanisme de chronographe par exemple, la source d'énergie de la montre étant une pile, alors que l'entraînement des disques se ferait au moyen de sources d'énergie mécanique.The winding of the barrels is done in one operation. It is also conceivable to provide the movement with a second winding crown, the barrel driving the finishing gear and those resulting in displaying the timed time being independently armed, one by the crown arranged at 3 o'clock, the others by a crown which can be at 9 o'clock for example. It is also possible to imagine a quartz watch equipped with a chronograph mechanism for example, the power source of the watch being a battery, while the drive of the disks would be made by means of mechanical energy sources .

Il est bien clair que le mouvement pourrait aussi être équipé d'un mécanisme automatique de remontoir assurant ou non l'armage de l'ensemble des barillets.It is clear that the movement could also be equipped with an automatic winding mechanism ensuring or not the winding of all the barrels.

Dans tous les cas, toutefois, l'énergie fournie au dispositif d'affichage ne provient pas du ressort de barillet ou du moteur assurant l'entraînement du rouage de finissage.In any case, however, the energy supplied to the display device does not come from the mainspring or the motor driving the finishing gear train.

Par ailleurs, les moyens assurant la liaison entre le ou les barillets complémentaires et le ou les disques d'affichage peuvent présenter de nombreuses variantes, fonction du but recherché et de la fantaisie du constructeur.Moreover, the means providing the connection between the one or more complementary barrels and the display disc or disks may have many variants, depending on the purpose and the fantasy of the manufacturer.

La montre telle que décrite est avantageusement équipée d'un indicateur de réserve de marche, par exemple celui décrit dans la demande EP EP 1 498 789 qui permet une indication du temps durant lequel la montre peut fonctionner normalement, en prenant en compte à la fois le barillet du mouvement de base et celui des unités.The watch as described is advantageously equipped with a power reserve indicator, for example that described in the EP application. EP 1 498 789 which allows an indication of the time during which the watch can function normally, taking into account both the barrel of the basic movement and that of the units.

Le dispositif décrit ci-dessus est directement monté sur la platine du mouvement. Il serait également possible de réaliser ce dispositif sur une platine complémentaire, formant ainsi un module à fixer sur le mouvement de base.The device described above is directly mounted on the movement stage. It would also be possible to realize this device on a complementary plate, thus forming a module to fix on the basic movement.

Ainsi, grâce aux caractéristiques que présente le mouvement selon l'invention, il est possible de réaliser une montre munie d'un affichage assuré par des disques de grandes dimensions, sans pour autant charger le rouage de finissage, en évitant ainsi d'affecter la précision de marche.Thus, thanks to the characteristics of the movement according to the invention, it is possible to make a watch provided with a display provided by large disks, without loading the finishing gear, thus avoiding affecting the precision of walking.
