Description

Domaine de l'inventionField of the invention

L'invention concerne un mouvement mécanique d'horlogerie comportant au moins un moyen de stockage d'énergie agencé pour entraîner un rouage dont un mobile de sortie est agencé pour pivoter autour d'un axe moteur, et comportant un résonateur rotatif lequel comporte au moins un mobile central, agencé pour pivoter autour d'un axe central, et comportant un mobile d'entrée agencé pour coopérer avec le mobile de sortie.The invention relates to a clockwork mechanical movement comprising at least one energy storage means arranged to drive a gear train of which an output gear is arranged to pivot about a motor axis, and comprising a rotary resonator which comprises at least a central mobile, arranged to pivot about a central axis, and having an input mobile arranged to cooperate with the output mobile.

L'invention concerne encore une montre comportant un tel mouvement.The invention also relates to a watch comprising such a movement.

L'invention concerne le domaine des bases de temps pour mouvements d'horlogerie mécaniques.The invention relates to the field of time bases for mechanical watch movements.

Arrière-plan de l'inventionBackground of the invention

La plupart des montres mécaniques actuelles sont munies d'un balancier-spiral et d'un échappement à ancre suisse. Le balancier-spiral constitue la base de temps de la montre. On l'appelle aussi résonateur. L'échappement, quant à lui, rempli deux fonctions principales:

  • entretenir les va-et-vient du résonateur ;
  • compter ces va-et-vient.
Most of the current mechanical watches are equipped with a sprung balance and a Swiss lever escapement. The sprung balance is the time base of the watch. It is also called resonator. The escapement, meanwhile, fulfills two main functions:
  • maintain the comings and goings of the resonator;
  • count these back and forth.

En plus de ces deux fonctions principales, l'échappement, doit être robuste, résister aux chocs, éviter de coincer le mouvement (renversement), et indéréglable dans le temps.In addition to these two main functions, the exhaust must be robust, withstand shocks, avoid trapping the movement (overturning), and foolproof over time.

L'échappement à ancre suisse, le plus généralement utilisé, a un rendement énergétique faible, de l'ordre de 30%. Ce faible rendement provient du fait que les mouvements de l'échappement sont saccadés, qu'il y a des chutes ou chemins perdus qui sont nécessaires pour s'accommoder des dispersions d'usinage, et aussi du fait que plusieurs composants se transmettent leur mouvement via des plans inclinés qui frottent les uns par rapport aux autres.The Swiss lever escapement, the most commonly used, has a low energy efficiency, of the order of 30%. This low efficiency comes from the fact that the movements of the exhaust are jerky, that there are falls or lost paths that are necessary to accommodate machining dispersions, and also that several components are transmitted their movement. via inclined planes that rub against each other.

Résumé de l'inventionSummary of the invention

La présente invention a pour objectif de supprimer les saccades de l'échappement, afin d'en augmenter le rendement. Pour atteindre cet objectif, on propose un résonateur rotatif, caractérisé notamment par la possibilité d'entretenir la rotation par un couple appliqué directement sur l'axe du résonateur, évitant ainsi les pertes dynamiques d'un échappement à ancre classique.The present invention aims to eliminate the saccades of the exhaust, in order to increase the efficiency. To achieve this objective, a rotary resonator is proposed, characterized in particular by the possibility of maintaining the rotation by a torque applied directly on the axis of the resonator, thus avoiding the dynamic losses of a classic anchor escapement.

Historiquement, les horlogers n'ont pas considéré les résonateurs rotatifs comme base de temps pour les montres car les résonateurs rotatifs ne sont généralement pas isochrones, et ils sont de surcroît sensibles à la gravité, donc à la position de la montre dans le champ de pesanteur.Historically, watchmakers have not considered rotary resonators as a time base for watches because rotary resonators are not usually isochronous, and they are also sensitive to gravity, therefore to the position of the watch in the field of view. gravity.

Un mécanisme comme le régulateur de Watt peut constituer une base de résonateur rotatif, mais au prix de modifications pour le rendre isochrone et insensible à la gravité. En effet, le régulateur de Watt est sensible à son orientation dans le champ de gravité, car le centre de masse global des deux masselottes se déplace lorsque l'amplitude change : les masselottes montent le long de l'axe lorsque l'amplitude augmente. Dès lors, la contribution de la gravité à la force de rappel fluctue avec l'orientation. De plus le régulateur de watt est anisochrone car la force de rappel des masselottes, par ressort et/ou par gravité ne répond pas à certaines conditions.A mechanism like the Watt regulator can be a rotational resonator base, but at the cost of modifications to make it isochronous and insensitive to gravity. Indeed, the Watt regulator is sensitive to its orientation in the gravity field, because the global center of mass of the two flyweights moves when the amplitude changes: the flyweights go up along the axis when the amplitude increases. Therefore, the contribution of gravity to the restoring force fluctuates with the orientation. In addition the watt regulator is anisochronous because the return force of the weights, spring and / or gravity does not meet certain conditions.

L'invention s'attache donc à remplir les conditions qui permettent d'avoir un résonateur rotatif utilisable comme base de temps pour un instrument horaire :

  • condition d'isochronisme : existence de forces de rappel élastiques (ou potentiel élastique) provoquant sur le centre de masse de chaque demi-bras une force centrale d'intensité proportionnelle à la distance entre l'axe de rotation et le centre de masse du demi-bras ;
  • condition d'insensibilité aux positions : utilisation d'au moins deux demi-bras guidés, de façon à pouvoir éloigner leur centre de masse de l'axe de rotation, tout en maintenant le centre de masse global du résonateur en position fixe ;
  • condition de forces de réactions nulles dans le support: utilisation de bras répartis en symétrie autour de l'axe, pour annuler les réactions dans les pivots à toutes les amplitudes.
The invention therefore seeks to fulfill the conditions that make it possible to have a rotary resonator that can be used as a time base for a time instrument:
  • isochronism condition: existence of elastic return forces (or elastic potential) causing on the center of mass of each half-arm a central force of intensity proportional to the distance between the axis of rotation and the center of mass of the half -arms ;
  • condition of insensitivity to the positions: use of at least two guided half-arms, so as to move their center of mass away from the axis of rotation, while maintaining the overall center of mass of the resonator in a fixed position;
  • condition of zero reaction forces in the support: use of arms distributed symmetrically about the axis, to cancel the reactions in the pivots at all amplitudes.

A cet effet, l'invention concerne un mouvement mécanique d'horlogerie selon la revendication 1.For this purpose, the invention relates to a mechanical clockwork movement according to claim 1.

L'invention concerne encore une montre comportant un tel mouvement.The invention also relates to a watch comprising such a movement.

Plus particulièrement, ce mécanisme résonateur a une structure de type pantographe.The demand EP16195399 of the same applicant relates to a resonator mechanism for a watch movement, comprising a mounted entrance mobile pivoting about an axis of rotation and subjected to a driving torque, and having a central mobile, integral in rotation with the input mobile about the axis of rotation and arranged to rotate continuously. This resonator mechanism comprises a plurality of N inertial elements, each movable in at least one degree of freedom with respect to the central mobile, and biased towards the axis of rotation by elastic return means, which are arranged to cause a return force on the center of mass of the inertial element. This resonator mechanism has a symmetry of rotation of order N. This resonator mechanism comprises means of kinematic connection between all the inertial elements, and which are arranged to maintain, at all times, all the centers of mass of the inertial elements to the same distance from the axis of rotation, and the elastic return means cause an elastic potential characterized by a particular relationship. More particularly, this resonator mechanism has a pantograph type structure.

Il s'agit ici d'améliorer un tel mécanisme. En effet, le couple d'entraînement et le couple de résistance aérodynamique génèrent une force radiale qui s'ajoute au potentiel élastique, et vient perturber l'isochronisme.This is to improve such a mechanism. Indeed, the driving torque and the aerodynamic resistance couple generate a radial force that adds to the elastic potential, and disturbs the isochronism.

La présente invention se propose d'orienter différemment le pivotement des éléments inertiels, afin de ne pas perturber l'isochronisme par l'entraînement ou des forces aérodynamiques tangentielles. La figure 1 illustre une variante de mécanisme résonateur selon l'invention, où le pivotement des éléments inertiels se fait orthogonalement au pivotement de l'entraînement.The present invention proposes to orient differently the pivoting of the inertial elements, so as not to disturb the isochronism by the drive or tangential aerodynamic forces. The figure 1 illustrates a variant of the resonator mechanism according to the invention, wherein the pivoting of the inertial elements is orthogonal to the pivoting of the drive.

La figure 2 montre que la liaison articulée complexe du mécanisme de la figure 1, découlant directement de la demande EP16195399 , peut disparaître au profit d'une structure très simple : la présente invention a l'avantage de combiner le mobile d'entraînement et le résonateur en une seule entité très simple à réaliser.The figure 2 shows that the complex articulated linkage of the mechanism of figure 1 , arising directly from the request EP16195399 , can disappear in favor of a very simple structure: the present invention has the advantage of combining the drive mobile and the resonator in a single entity very simple to achieve.

Ce mécanisme évite les chocs et les frottements inhérents à des mécanismes d'entraînement à rainure, ou bielle-manivelle, mal accordés.This mechanism avoids the shocks and the friction inherent to mechanisms of drive with groove, or crank-crank, poorly tuned.

L'invention évite la multiplication inutile d'éléments élastiques, entre la platine et l'élément inertiel d'une part, et entre le mobile d'entraînement et l'élément inertiel d'autre part.The invention avoids the unnecessary multiplication of elastic elements, between the plate and the inertial element on the one hand, and between the drive mobile and the inertial element on the other hand.

Plus particulièrement, ce résonateur rotatif 10 présente, dans une position de repos, une symétrie de rotation autour de l'axe central A, d'ordre N, où N est un entier, supérieur ou égal à 2.More particularly, this rotary resonator 10 has, in a rest position, a symmetry of rotation about the central axis A, of order N, where N is an integer greater than or equal to 2.

Plus particulièrement, les éléments inertiels 3 que comporte le résonateur rotatif 10 sont, dans une position de repos, en symétrie de rotation autour de l'axe central A, d'ordre N, où N est un entier, supérieur ou égal à 2.More particularly, the inertial elements 3 that comprises the rotary resonator 10 are, in a rest position, rotational symmetry around the central axis A, of order N, where N is an integer greater than or equal to 2.

Plus particulièrement encore, chaque élément inertiel 3 présente une symétrie de rotation d'ordre 2 autour de son axe secondaire B.More particularly, each inertial element 3 has a rotation symmetry of order 2 around its secondary axis B.

Dans une variante, au moins un élément de rappel élastique 4 est fixé à une première extrémité au mobile central 1, et à une deuxième extrémité à l'élément inertiel 3.In a variant, at least one elastic return element 4 is fixed at a first end to the central mobile 1, and at a second end to the inertial element 3.

Dans une autre variante, qui peut naturellement être combinée avec la précédente, au moins un élément de rappel élastique 4 est fixé à une première extrémité à un élément inertiel 3, et à une deuxième extrémité à un autre élément inertiel 3.In another variant, which can naturally be combined with the preceding one, at least one elastic return element 4 is fixed at one end to an inertial element 3, and at a second end to another inertial element 3.

Dans une autre variante encore, visible notamment sur les figures 3 et 4, chaque élément de rappel élastique 4 est fixé à une première extrémité au mobile central 1, et à une deuxième extrémité à un élément inertiel 3.In another variant, visible in particular on figures 3 and 4 each elastic return element 4 is fixed at a first end to the central mobile 1, and at a second end to an inertial element 3.

Plus particulièrement, et tel que visible sur les réalisations illustrées, non limitatives, tous les éléments inertiels 3 d'un même résonateur rotatif 10 sont agencés pour pivoter autour d'un axe secondaire B commun.More particularly, and as visible in the illustrated embodiments, not limiting, all the inertial elements 3 of the same rotary resonator 10 are arranged to pivot about a common secondary axis B.

Dans des variantes particulières visibles notamment aux figures 3 et 4, au moins un dit élément inertiel 3 est au moins 5 fois plus long que large, et au moins 5 fois plus large qu'épais.In particular variants visible in particular to figures 3 and 4 at least one said inertial element 3 is at least 5 times longer than wide, and at least 5 times wider than thick.

Dans un mode de réalisation avantageux, le résonateur rotatif 10 comporte au moins un guidage flexible, pour assurer le pivotement et le rappel élastique d'au moins un élément inertiel 3 par rapport au mobile central 1.In an advantageous embodiment, the rotary resonator 10 comprises at least one flexible guide, to ensure the pivoting and the elastic return of at least one inertial element 3 with respect to the central mobile 1.

Ce guidage flexible peut être réalisé de différentes façons : lames flexibles ou lames à cols, agencées de façon croisée en plan, ou selon des plans parallèles et croisées en projection sur un de ces plans parallèles, ou encore agencées selon une configuration RCC (Remote Center Compliance) c'est-à-dire à centre de rotation déporté, les lames faisant un vé entre elles, ou autres.This flexible guide can be achieved in different ways: flexible blades or collared blades, arranged in a plane crosswise manner, or in parallel planes and crossed in projection on one of these parallel planes, or arranged according to a configuration RCC (Remote Center Compliance) that is to say, to offset center of rotation, the blades making a vee between them, or others.

L'utilisation de tels guidages flexibles pour réaliser la fonction de guidage rotatif et de rappel élastique permet de supprimer les frottements inhérents à un pivot traditionnel de type arbre-palier, ou similaire.The use of such flexible guides to perform the function of rotary guiding and elastic return eliminates the friction inherent in a traditional shaft-bearing pivot, or the like.

Selon le mode de réalisation, ces guidages flexibles peuvent être, ou bien rapportés sur le mobile central 1 et/ou sur un élément inertiel 3, ou être monobloc avec au moins l'un des deux, ou les deux. Les exécutions monobloc peuvent être en matériau micro-usinable, mis en oeuvre par procédé « Liga » ou « Mems » ou similaire, en matériau au moins partiellement amorphe, en silicium et oxyde de silicium, en « DLC » (diamant like carbon), ou autre.According to the embodiment, these flexible guides can be, or reported on the central mobile 1 and / or on an inertial element 3, or be monobloc with at least one or both. The monobloc embodiments may be made of micro-machinable material, implemented by "Liga" or "Mems" method or the like, of at least partially amorphous material, silicon and silicon oxide, "DLC" (diamond like carbon), Or other.

Plus particulièrement, ce guidage flexible est un pivot à lames qui sont, ou croisées coplanaires, ou croisées en projection sur un plan de projection perpendiculaire à l'axe central A comme dans la réalisation de la figure 4. Cette configuration présente l'avantage de garantir des performances de marche excellentes.More particularly, this flexible guide is a pivot with blades which are, or crossed coplanar, or crossed in projection on a projection plane perpendicular to the central axis A as in the embodiment of the figure 4 . This configuration has the advantage of guaranteeing excellent performance.

Il est avantageux que le centre de masse global reste fixe, et que le cumul des éventuels déplacements parasites des centres de masse individuels des éléments inertiels, lors de leur pivotement, s'annule. C'est-à-dire que le centre de masse global de tout le résonateur rotatif10 reste fixe indépendamment de l'amplitude. Ceci peut être obtenu notamment par la combinaison de la symétrie géométrique en rotation, et par le choix de guidage flexibles identiques pour tout le résonateur rotatif 10 : chaque élément inertiel 3 qui le compose est rappelé par le même guidage flexible.It is advantageous that the overall center of mass remains fixed, and that the cumulation of possible parasitic displacements of the individual centers of mass of the inertial elements, during their pivoting, is canceled. That is, the overall center of mass of the entire rotational resonator remains fixed regardless of amplitude. This can be achieved in particular by the combination of geometric symmetry in rotation, and by the choice of identical flexible guidance for the entire rotary resonator 10: each inertial element 3 which composes it is recalled by the same flexible guide.

L'utilisation des lames croisées, dans des géométries particulières, permet, encore, d'assurer que le couple de rappel provoqué par le guidage flexible sur chacun des éléments inertiels est proportionnel au sinus du double de l'angle de pivotement de cet élément inertiel 3.The use of the crossed blades, in particular geometries, makes it possible, again, to ensure that the return torque caused by the flexible guidance on each of the inertial elements is proportional to the sine of the double of the pivot angle of this inertial element. 3.

Deux agencements particuliers, nullement limitatifs, sont décrits ci-après pour exposer des moyens d'y parvenir.Two particular arrangements, in no way limiting, are described below to explain ways to achieve this.

La figure 5 montre un pivot à lames croisées asymétrique : ce guidage flexible est agencé pour imprimer à l'élément inertiel 3 un couple de rappel proportionnel au sinus du double de l'angle de pivotement dudit élément inertiel 3. Ce guidage flexible comporte deux lames flexibles 31, 32, asymétriques joignant chacune un premier encastrement 41, 42, du mobile central 1 à un deuxième encastrement 51, 52 de l'élément inertiel 3. Ces premiers encastrements 41, 42, définissent avec les deuxièmes encastrements 51, 52, respectifs deux directions principales de lames DL1, DL2. Le mobile central 1 et l'élément inertiel 3 sont chacun plus rigide que chacune des lames flexibles 31, 32. Les deux directions principales de lames DL1, DL2, définissent un axe de pivotement théorique D, à leur croisement quand ces deux lames flexibles 31, 32 sont coplanaires, ou au croisement de leurs projections sur le plan de projection quand les deux lames flexibles 31, 32, se développent sur deux niveaux parallèles au plan de projection mais ne sont pas coplanaires comme dans le cas de la figure 4, et selon un angle au sommet α égal à 112.5°. La deuxième 32 de ces lames a, entre ses encastrements opposés, une deuxième longueur totale L2 triple de la première longueur totale L1 de la première 31 des lames. Et les distances entre les premiers encastrements 41, 42, et l'axe de pivotement théorique D sont, pour la deuxième lame 32 une deuxième distance axiale D2 égale à 0.875 fois la deuxième longueur totale L2, et, pour la première lame 31, une première distance axiale D1 égale à 0.175 fois la première longueur totale L1.The figure 5 shows an asymmetrical cross-leaf swivel: this flexible guide is arranged to print to the inertial element 3 a return torque proportional to the sine of twice the swivel angle of said inertial element 3. This flexible guide comprises two flexible blades 31, 32, asymmetrical each joining a first recess 41, 42, the central mobile 1 to a second recess 51, 52 of the inertial element 3. These first recesses 41, 42, define with the second recesses 51, 52, respectively two main directions DL1, DL2 blades. The central mobile 1 and the inertial element 3 are each more rigid than each of the flexible blades 31, 32. The two main blade directions DL1, DL2, define a theoretical pivot axis D, at their intersection when these two flexible blades 31 , 32 are coplanar, or at the crossroads of their projections on the plane of projection when the two flexible blades 31, 32, develop on two levels parallel to the plane of projection but are not coplanar as in the case of the figure 4 , and at an apex angle α equal to 112.5 °. The second 32 of these blades has, between its opposite recesses, a second total length L2 triple of the first total length L1 of the first 31 of the blades. And the distances between the first recesses 41, 42, and the theoretical pivot axis D are, for the second blade 32 a second axial distance D2 equal to 0.875 times the second total length L2, and, for the first blade 31, a first axial distance D1 equal to 0.175 times the first total length L1.

La figure 6 montre une configuration RCC, à centre de rotation déporté, qui n'est pas réalisée de façon monobloc, mais où les lames sont contraintes angulairement d'un faible angle, au voisinage d'au moins une de leurs extrémités, par exemple par introduction d'une fente déportée latéralement par rapport à la direction de lame théorique. Le guidage flexible réalisé par ce pivot RCC particulier permet aussi de créer un couple proportionnel au sinus de deux fois l'angle, ledit guidage flexible est réalisé par un pivot à lames à centre de rotation déporté constituant un pivot virtuel, dont l'encastrement des lames 31, 32, dans des logements 51, 52, que comporte le mobile central 1 et/ou le élément inertiel 3 résulte d'une précontrainte angulaire de 0.15 radian, avec une torsion à l'encastrement, l'angle au sommet que forment les directions des encastrements des lames 31, 32, au niveau du pivot virtuel est de 52.642°, et la distance entre le pivot virtuel et l'encastrement le plus proche est égale à 0.268864 fois la longueur de chacune des lames 31, 32, qui sont ici identiques, entre leurs encastrements à l'état libre avant la précontrainte de leur extrémité.The figure 6 shows a RCC configuration, with a remote center of rotation, which is not carried out integrally, but where the blades are angularly constrained by a small angle, in the vicinity of at least one of their ends, for example by introduction of a slot offset laterally with respect to the theoretical blade direction. The flexible guide provided by this particular RCC pivot also makes it possible to create a torque proportional to the sine of twice the angle, said flexible guide is produced by a pivot pin with a remote center of rotation constituting a virtual pivot, the embedding of which blades 31, 32, in housings 51, 52, that includes the central mobile 1 and / or the inertial element 3 results from an angular preload of 0.15 radian, with a torsion to the embedding, the angle at the summit that form the directions of the recesses of the blades 31, 32, at the virtual pivot is 52.642 °, and the distance between the virtual pivot and the nearest recess is equal to 0.268864 times the length of each of the blades 31, 32, which are here identical, between their embedding in the free state before the prestressing of their end.

Plus particulièrement, ce guidage flexible est compensé thermiquement.More particularly, this flexible guide is thermally compensated.

Plus particulièrement encore, ce guidage flexible comporte des lames en silicium oxydé, sur lesquelles une croissance différentielle de dioxyde de silicium lors d'un traitement thermique permet de mettre sous forte précontrainte des éléments de plus faible section, tels que des lames au sein d'un ensemble monobloc.More particularly, this flexible guide comprises blades of oxidized silicon, on which a differential growth of silicon dioxide during a heat treatment makes it possible to put under high prestressing elements of smaller section, such as blades within a monobloc set.

Dans la variante de la figure 1, le résonateur rotatif 10 comporte, articulés avec certains éléments inertiels 3, des éléments de liaison cinétique supplémentaires 5, qui constituent avec ces éléments inertiels 3 une structure articulée de type pantographe, et qui sont agencés pour augmenter le déploiement radial du résonateur rotatif 10 en limitant sa hauteur selon l'axe central A.In the variant of the figure 1 , the rotary resonator 10 comprises, articulated with certain inertial elements 3, additional kinetic connecting elements 5, which constitute with these inertial elements 3 a structure articulated pantograph type, and which are arranged to increase the radial deployment of the rotary resonator 10 by limiting its height along the central axis A.

Dans la variante de la figure 7, le mouvement 100 comporte au moins un axe principal P d'affichage par aiguilles ou disques, et l'axe central A est parallèle à cet axe principal P.In the variant of the figure 7 , the movement 100 comprises at least one main axis P of display by needles or disks, and the central axis A is parallel to this main axis P.

Dans la variante de la figure 8, l'axe central A est cette fois perpendiculaire à l'axe principal P.In the variant of the figure 8 , the central axis A is this time perpendicular to the main axis P.

Par exemple, le mobile de sortie du rouage 300 est une vis sans fin, agencée pour coopérer avec un pignon qui constitue le mobile d'entrée 2.For example, the mobile output of gear train 300 is a worm gear, arranged to cooperate with a pinion which constitutes the input mobile 2.

De façon particulière, le résonateur rotatif 10 comporte seulement deux ou trois éléments inertiels 3. En effet, un compromis est à trouver entre les performances et l'encombrement, et un résonateur à deux éléments inertiels en symétrie de rotation assure les performances requises.In particular, the rotary resonator 10 comprises only two or three inertial elements 3. Indeed, a compromise is to be found between the performance and the bulk, and a resonator with two inertial elements rotational symmetry ensures the required performance.

Dans une variante avantageuse, le pivotement du mobile central 1 est effectué sur au moins un pivot magnétique, de façon à obtenir le meilleur rendement.In an advantageous variant, the pivoting of the central mobile unit 1 is performed on at least one magnetic pivot, so as to obtain the best efficiency.

L'invention concerne encore une montre mécanique 1000 comportant au moins un tel mouvement.The invention also relates to a mechanical watch 1000 comprising at least one such movement.

La présente invention présente des avantages importants :

  • la suppression du travail du frottement des pivots d'un balancier-spiral usuel, pour augmenter le facteur de qualité du résonateur ;
  • la suppression des saccades de l'échappement afin d'augmenter le rendement d'échappement ;
  • l'augmentation de la réserve de marche des montres mécaniques actuelles ;
  • l'augmentation de la précision des montres mécaniques actuelles.
The present invention has important advantages:
  • the elimination of the work of the friction of the pivots of a conventional balance-spring, to increase the quality factor of the resonator;
  • the suppression of saccades of the exhaust in order to increase the exhaust efficiency;
  • the increase in the power reserve of current mechanical watches;
  • the increase of the precision of the current mechanical watches.

Pour une taille de mouvement donné, on s'attend à quintupler l'autonomie de la montre, et à doubler le pouvoir réglant de la montre. Cela revient à dire que l'invention permet un gain d'un facteur 10 sur les performances du mouvement.For a given movement size, it is expected to increase the autonomy of the watch five times, and to double the power of the watch. That is to say that the invention allows a gain of a factor 10 on the performance of the movement.
