Definitions

  • the information which the known devices, in accordance with the preamble of claim 1, are intended to protect, consists of advertisements which it is intended to appear on sheets of paper and each of which is placed in a recess in the bottom of a watch case protected by a one-way crystal set in this back (CH-A-29 191).
  • watches equipped with these known protective devices are intended for merchants, for example coffee, who distribute them free of charge, as gifts, to their best customers. These are therefore relatively inexpensive watches, the protective device of which clearly does not aim to prevent fraudulent copies.
  • Similar devices have also been associated with the movement of the watch, essentially with the aim of simplifying the numbering. They include a plate glued into a recess in the plate of the watch movement. If the plate is transparent, the serial number of the movement is applied to its reverse; if it is metallic, it is applied to the obverse (US-A-3,983,386).
  • the device defined by claim 1 puts a brake on counterfeits.
  • the transparent sapphire plate that it includes is not a common product. For those who are not seriously installed in the sector, obtaining it would represent a big investment. Ensuring an indissoluble bonding to a part of the watch case without compromising the transparency does not enter the ropes of those who try, at low cost, to pass their junk for parts of major brands. Thus, the indications of origin, which appear through such a brochure, give the general public a serious guarantee of their authenticity.
  • claim 3 allow the manufacturer or its distributors to individualize each watch produced or sold, thereby making it possible to quickly distinguish them from counterfeits.
  • the authentication plate can, at the discretion of the producer, be glued to practically any of the parts of a watch case.
  • the first four embodiments relate to watches in which the glass completely covers the case, which is designed as described in European patent application No. EP-A-0 064 951 of the applicant (published on 17.11.82).
  • the ornamental, non-transparent elements which constitute the visible face of the box surrounding the dial, therefore form a one-piece assembly with the glass, to which they are permanently attached and this assembly is fixed by screws engaged from the bottom side of the box in sockets integral with said assembly and located under its ornamental elements, these screws serving at the same time for fixing the bottom.
  • the glass 1 itself, made of sapphire, has the general shape of a rectangle. Its angles are cut. Its upper face 2, flat, is framed by bevels 3, 4, 5.
  • the periphery of the glass 1 is opacified by ornamental elements (not shown) permanently fixed to the flat lower face 6 of the glass 1 and extending up to at the edge 7 of the transparent area of the glass, through which the watch face appears.
  • a rectangular plate 8, also made of transparent sapphire, is indissoluble glued to the face 2 of the glass 1 and embossed thereon.
  • the adhesive must however be applied with care, in order to ultimately form a thin film, absolutely compact, that is to say free of air bubbles under the entire surface of the wafer 8, but without overflowing this last.
  • the adhesives which can be used for this purpose are relatively fluid in the latent state. Some take only under the action of ultraviolet rays; others under the effect of heat at a determined temperature, but this then very quickly. When the wafer 8 has thus been glued to the glass 1, no difference in transparency can be discerned between the area of the glass 1 covered by the wafer 8 and the rest of the glass 1.
  • bevels 9 are formed along the upper edges of the plate 8.
  • Fig. 1 shows that indications 10, 11 appear through the plate 8.
  • One of them, 10, is constituted by the trademark of the watch.
  • This can be applied to the face 6 of the glass 1 by vacuum spraying, for example at the same time as such a layer is formed on this face to opacify a peripheral zone.
  • the mark 10 can also be applied in the same way on the face 2 of the glass 1.
  • this mark 10 will however be applied in the manner described on the reverse of the wafer 8. In this way, the mark 10 will always be well centered in the plate 8, even if the latter should not be glued to the glass 1 in the exact desired position.
  • the reverse of the plate 8 can also serve as a receptacle for other indications than the trademark, such as it, to authenticate the origin of the watch.
  • the indication 11 in FIG. 1 composed for example of specific letters and numbers, may constitute, in combination with the analogous indication 12, engraved on the bottom 13 of the watch case (Fig. 3), a code making it possible to individualize each watch produced. To do this, it suffices to modify at least one of the indications 11, 12 from one watch to another. In this way, a determined pair of indications 11, 12 will only be found on one of the watches produced. By listing these pairs of indications for the agencies that represent the brand, they can immediately distinguish a watch whose origin is authentic from a counterfeit.
  • the application of the device according to the invention is not limited to rectangular watches. It can be used with the same advantages, for example in the case of round watches, as shown in the second embodiment (Fig. 4 and 5).
  • it is a plate 14, also circular, which is bonded to the round glass 15 covering the entire upper face of the case of the watch.
  • Indications 16, 17, of the same nature as indications 10, 11 of the first embodiment, are applied to the reverse of the plate 14.
  • the latter is glued in the zone 18 of the glass 15, which is opacified by the ornamental elements 19 glued under the periphery of the glass 15 (Fig. 5).
  • the third embodiment shows in particular a plate 20, the same shape as the glass 1 and which is just a little smaller than the flat upper face 2 of the latter.
  • the plate 20 thus extends above the zone 21 of the glass 1, which is opacified by the ornamental elements (not shown) that the planar lower face 6 of the glass carries at its periphery.
  • the plate 20 not only has the effect of enriching the relief of the glass, by making it appear with a well-worked external face, but also that of enhancing the appearance of the ornamental elements of the area.
  • the round plate 25 of the fourth embodiment (Fig. 8 and 9), glued to the round glass 15, shows that a large plate is also usable in the case where the housing is round and has its upper face entirely covered by glass.
  • the watch glass is not the only support capable of receiving an authentication plate such as those described in the first four embodiments.
  • the plate 8 can be glued to the part of the frame 27 extending beyond the glass 26, as shown in the fifth embodiment (Fig. 10 and 11).
  • the sixth embodiment shows that the same possibility also exists for the round plate 14, which is glued to the ring 28, itself glued under the glass 29.
  • the bottom of the housing can also serve as a support for a plate of the kind described above. If it is rectangular, like the bottom 30 of the seventh embodiment (Figs. 14 and 15), the plate 31 that will be glued to it will have a shape harmonizing with that of the bottom, and we will also glue a circular plate 32 on the bottom 33 of a round housing (Figs. 16 and 17).
  • the reverse of the sapphire plate can naturally serve as a receptacle for indications of a nature to authenticate the origin of the watch, such as the trademark and / or a trade mark.
  • encrypted indication which, in combination with a second indication, also encrypted, but different, applied to another visible part of the watch, will form an identification code of the producer or distributor of these watches, individualizing each of these.
  • the authentication plates described can also be bonded to other materials than sapphire glass, the hard metal of the frame or ring appearing as a bezel or the steel of the back, for example on a bezel or a plated back or chromed or on precious metal parts.
  • the device according to the invention can be applied to any other shape of part, polygonal with straight or curved sides.
  • the shape of the authentication plate used in these cases can, in fact, always be harmonized with that of the watch.

Description

Les informations que les dispositifs connus, conformes au préambule de la revendication 1, sont destinés à protéger, sont constituées par des réclames qu'il est prévu de faire figurer sur des feuilles de papier et dont chacune est placée dans une creusure du fond d'un boîtier de montre et protégée par une glace sans tain sertie dans ce fond (CH-A-29 191).The information which the known devices, in accordance with the preamble of claim 1, are intended to protect, consists of advertisements which it is intended to appear on sheets of paper and each of which is placed in a recess in the bottom of a watch case protected by a one-way crystal set in this back (CH-A-29 191).

De toute évidence, les montres équipées de ces dispositifs protecteurs connus sont destinées à des marchands, par exemple de café, qui les distribuent gratuitement, comme cadeaux, à leurs meilleurs clients. Il s'agit donc là de montres relativement bon marché, dont le dispositif protecteur ne vise manifestement pas à prévenir les copies frauduleuses.Obviously, watches equipped with these known protective devices are intended for merchants, for example coffee, who distribute them free of charge, as gifts, to their best customers. These are therefore relatively inexpensive watches, the protective device of which clearly does not aim to prevent fraudulent copies.

Des dispositifs analogues ont aussi été associés au mouvement de la montre, essentiellement dans le but d'en simplifier la numérotation. Ils comprennent une plaquette collée dans une creusure de la platine du mouvement de la montre. Si la plaquette est transparente, le numéro d'ordre du mouvement est appliqué à son revers; si elle est métallique, il est appliqué à l'avers (US-A-3 983 386).Similar devices have also been associated with the movement of the watch, essentially with the aim of simplifying the numbering. They include a plate glued into a recess in the plate of the watch movement. If the plate is transparent, the serial number of the movement is applied to its reverse; if it is metallic, it is applied to the obverse (US-A-3,983,386).

L'information fournie de cette façon est destinée exclusivement aux rhabilleurs. Elle leur permet d'identifier la pièce en réparation, s'ils doivent commander des pièces de rechange à la fabrique. Par ailleurs, ce dispositif connu n'est pratiquement pas applicable à un verre de montre en saphir et les fonds des boîtes ne sont pas assez épais pour y pratiquer une creusure capable de recevoir une plaquette.The information provided in this way is intended exclusively for dressers. It allows them to identify the part being repaired, if they have to order spare parts from the factory. Furthermore, this known device is practically not applicable to a sapphire watch glass and the case backs are not thick enough to make a recess capable of receiving a wafer there.

On connaît encore des dispositifs associés à des pendulettes, qui assurent la protection d'une image publicitaire, par exemple sur carte postale, en collant sur l'image une feuille mince de celluloïd (FR-A-702 812). Si un tel dispositif protecteur est suffisant pour une pendulette, il ne résisterait pas longtemps sur une montre destinée à être portée tous les jours.There are also known devices associated with clocks, which protect an advertising image, for example on a postcard, by sticking a thin sheet of celluloid on the image (FR-A-702 812). If such a protective device is sufficient for a clock, it would not last long on a watch intended to be worn every day.

Tous ces dispositifs connus confèrent une certaine protection mécanique à une indication. La facilité avec laquelle ils peuvent être réalisés les rend toutefois impropres à protéger les indications d'origine d'une montre au point de donner à son acheteur la garantie d'acquérir un produit émanant vraiment de l'origine désirée.All these known devices confer a certain mechanical protection on an indication. The ease with which they can be made, however, makes them unsuitable for protecting the indications of origin of a watch to the point of giving its buyer the guarantee of acquiring a product really emanating from the desired origin.

Jusqu'à présent, les fabricants de montres de qualité supérieure indiquent généralement cette origine en appliquant leur marque de fabrique ou de commerce sur le cadran de leurs montres.Until now, manufacturers of high-quality watches have generally indicated this origin by applying their trademark on the dial of their watches.

Or, la prolifération des moyens de production des pièces de l'habillement des montres, en particulier des cadrans, a précisément été suivie d'une production parallèle, sans cesse croissante, de contrefaçons affublant des montres de pacotille de marques prestigieuses, au grand dam des acheteurs. Le moyen traditionnel d'indiquer l'origine d'une montre a, il est vrai, facilité ces contrefaçons car, pour être en mesure d'appliquer une marque sur un cadran, point n'est besoin d'envisager de gros investissements pour qui possède déjà l'équipement nécessaire à la fabrication de cadrans.However, the proliferation of the means of production of the parts of the clothing of the watches, in particular of the dials, was precisely followed by a parallel production, constantly increasing, of counterfeits disguising junk watches of prestigious brands, to the great displeasure buyers. The traditional way of indicating the origin of a watch has, it is true, facilitated these counterfeits because, to be able to apply a mark on a dial, there is no need to consider large investments for which already has the equipment needed to manufacture dials.

Ainsi, le simple examen extérieur, dont le grand public doit se contenter, ne permet plus d'en déduire que l'indication d'origine apparaissant sur la montre est authentique.Thus, a simple external examination, which the general public must be satisfied with, no longer allows us to deduce that the indication of origin appearing on the watch is authentic.

Le dispositif défini par la revendication 1 met un frein aux contrefaçons. La plaquette transparente en saphir qu'il comprend n'est pas un produit courant. Pour qui n'est pas installé sérieusement dans la branche, son obtention représenterait un gros investissement. En assurer un collage indissoluble à une pièce du boîtier de la montre sans compromettre la transparence n'entre pas non plus dans les cordes de ceux qui tentent, à vil prix, de faire passer leur camelote pour des pièces de grandes marques. Ainsi, les indications d'origine, qui apparaissent à travers une telle plaquette, donnent au grand public une sérieuse garantie de leur authenticité.The device defined by claim 1 puts a brake on counterfeits. The transparent sapphire plate that it includes is not a common product. For those who are not seriously installed in the sector, obtaining it would represent a big investment. Ensuring an indissoluble bonding to a part of the watch case without compromising the transparency does not enter the ropes of those who try, at low cost, to pass their junk for parts of major brands. Thus, the indications of origin, which appear through such a brochure, give the general public a serious guarantee of their authenticity.

Les formes spéciales d'exécution définies par la revendication 2 offrent une garantie supplémentaire. Il faut, en effet, que les indications prises en sandwich entre la plaquette collée et son support soient appliquées avec soin, afin que les colles indissolubles utilisées ne les altèrent pas.The special forms of execution defined by claim 2 offer an additional guarantee. It is necessary, in fact, that the indications sandwiched between the glued plate and its support are applied with care, so that the indissoluble glues used do not alter them.

Les particularités définies par la revendication 3 permettent au fabricant ou à ses distributeurs d'individualiser chaque montre produite ou vendue, permettant par là de les distinguer rapidement des contrefaçons.The features defined by claim 3 allow the manufacturer or its distributors to individualize each watch produced or sold, thereby making it possible to quickly distinguish them from counterfeits.

Il ressort, enfin, des revendications 4 à 6 que la plaquette d'authentification peut, au gré du producteur, être collée pratiquement sur n'importe laquelle des pièces d'un boîtier de montre.It finally appears from claims 4 to 6 that the authentication plate can, at the discretion of the producer, be glued to practically any of the parts of a watch case.

Eight embodiments of the device according to the invention are shown schematically and simply by way of example in the drawing in which:
  • Fig. 1 is a partial plan view of a part of the first embodiment;
  • Fig. 2 is a cross section of the part shown in FIG. 1;
  • Fig. 3 is a bottom view of this first embodiment;
  • Fig. 4, similar to FIG. 1 is a partial plan view of a part of the second embodiment;
  • Fig. 5 is a partial radial section of this second embodiment;
  • Fig. 6 is a plan view of a part of the third embodiment, of which
  • Fig. 7 is a cross section;
  • Fig. 8 is a plan view of a part of the fourth embodiment, of which
  • Fig. 9 is a view in diametral section;
  • Fig. 10 is a partial plan view of a part of the fifth embodiment, of which
  • Fig. 11 is a partial section;
  • Fig. 12, similar to FIG. 10 is a partial plan view of a part of the sixth embodiment, of which
  • Fig. 13 is a partial section;
  • Fig. 14 is a bottom view of the seventh embodiment;
  • Fig. 15 is an elevational view of part of FIG. 14;
  • Fig. 16 is a bottom view of the eighth embodiment, and
  • Fig. 17 is an elevational view of part of FIG. 16.

Les quatre premières formes d'exécution (Fig. 1 à 9) ont trait à des montres dans lesquelles le verre recouvre entièrement le boîtier, qui est conçu de la façon décrite dans la demande de brevet européen N° EP-A-0 064 951 de la déposante (publiée en date du 17.11.82). Les éléments ornementaux, non transparents, qui constituent la face visible de la boîte entourant le cadran, forment donc un ensemble monobloc avec le verre, auquel ils sont attenants de façon définitive et cet ensemble est fixé par des vis engagées depuis le côté fond de la boîte dans des douilles solidaires du dit ensemble et se trouvant sous ses éléments ornementaux, ces vis servant en même temps à la fixation du fond.The first four embodiments (Fig. 1 to 9) relate to watches in which the glass completely covers the case, which is designed as described in European patent application No. EP-A-0 064 951 of the applicant (published on 17.11.82). The ornamental, non-transparent elements, which constitute the visible face of the box surrounding the dial, therefore form a one-piece assembly with the glass, to which they are permanently attached and this assembly is fixed by screws engaged from the bottom side of the box in sockets integral with said assembly and located under its ornamental elements, these screws serving at the same time for fixing the bottom.

Ainsi, dans la première forme d'exécution (Fig. 1 à 3), le verre 1 proprement dit, en saphir, a la forme générale d'un rectangle. Ses angles sont coupés. Sa face supérieure 2, plane, est encadrée de biseaux 3, 4, 5. La périphérie du verre 1 est opacifiée par des éléments ornementaux (non représentés) fixés à demeure à la face inférieure plane 6 du verre 1 et s'étendant jusqu'au bord 7 de l'aire transparente du verre, à travers laquelle apparaît le cadran de la montre. Une plaquette rectangulaire 8, également en saphir transparent, est collée de façon indissoluble à la face 2 du verre 1 et fait relief sur celle-ci.Thus, in the first embodiment (Fig. 1 to 3), the glass 1 itself, made of sapphire, has the general shape of a rectangle. Its angles are cut. Its upper face 2, flat, is framed by bevels 3, 4, 5. The periphery of the glass 1 is opacified by ornamental elements (not shown) permanently fixed to the flat lower face 6 of the glass 1 and extending up to at the edge 7 of the transparent area of the glass, through which the watch face appears. A rectangular plate 8, also made of transparent sapphire, is indissoluble glued to the face 2 of the glass 1 and embossed thereon.

On trouve, en effet, sur le marché des colles qui sont absolument transparentes, produisent une adhérence de plusieurs kilogrammes-force par millimètre carré et résistent à tous les agents chimiques auxquels une montre risque d'être exposée. Dans ces conditions, il est clair que la plaquette 8 ou le verre 1 se briseront avant qu'on ne soit parvenu à les séparer l'un de l'autre.In fact, there are adhesives on the market which are absolutely transparent, produce an adhesion of several kilograms-force per square millimeter and resist all the chemical agents to which a watch risks being exposed. Under these conditions, it is clear that the wafer 8 or the glass 1 will break before we have managed to separate them from each other.

La colle doit cependant être appliquée avec soin, afin de former, en définitive, un film mince, absolument compact, c'est-à-dire exempt de bulles d'air sous toute la surface de la plaquette 8, mais sans déborder de cette dernière. Les colles utilisables à cet effet sont relativement fluides à l'état latent. Certaines prennent uniquement sous l'action de rayons ultra-violets; d'autres sous l'effet de la chaleur à une température déterminée, mais cela, alors très rapidement. Lorsque la plaquette 8 a ainsi été collée au verre 1, on ne discerne à l'oeil nu aucune différence de transparence entre la zone du verre 1 recouverte par la plaquette 8 et le reste du verre 1.The adhesive must however be applied with care, in order to ultimately form a thin film, absolutely compact, that is to say free of air bubbles under the entire surface of the wafer 8, but without overflowing this last. The adhesives which can be used for this purpose are relatively fluid in the latent state. Some take only under the action of ultraviolet rays; others under the effect of heat at a determined temperature, but this then very quickly. When the wafer 8 has thus been glued to the glass 1, no difference in transparency can be discerned between the area of the glass 1 covered by the wafer 8 and the rest of the glass 1.

Pour ne pas endommager les vêtements et éviter des égrisures à la suite de chocs, des biseaux 9 sont formés le long des arêtes supérieures de la plaquette 8.In order not to damage the clothes and to avoid scratches as a result of impacts, bevels 9 are formed along the upper edges of the plate 8.

La Fig. 1 montre que des indications 10, 11 apparaissent à travers la plaquette 8. L'une d'elles, 10, est constituée par la marque de fabrique de la montre. Celle-ci peut être appliquée sur la face 6 du verre 1 par vaporisation sous vide, par exemple en même temps qu'une telle couche est formée sur cette face pour en opacifier une zone périphérique. La marque 10 peut aussi être appliquée de la même façon sur la face 2 du verre 1. De préférence, cette marque 10 sera cependant appliquée de la façon décrite au revers de la plaquette 8. De cette façon, la marque 10 sera toujours bien centrée dans la plaquette 8, même si cette dernière ne devait pas être collée sur le verre 1 dans la position exacte voulue.Fig. 1 shows that indications 10, 11 appear through the plate 8. One of them, 10, is constituted by the trademark of the watch. This can be applied to the face 6 of the glass 1 by vacuum spraying, for example at the same time as such a layer is formed on this face to opacify a peripheral zone. The mark 10 can also be applied in the same way on the face 2 of the glass 1. Preferably, this mark 10 will however be applied in the manner described on the reverse of the wafer 8. In this way, the mark 10 will always be well centered in the plate 8, even if the latter should not be glued to the glass 1 in the exact desired position.

A lui seul, ce mode d'application de la marque de fabrique sur une montre offre déjà au public une sérieuse garantie de l'authenticité de l'origine de la montre, car l'équipement de la plupart des entreprises marronnes, qui font industrie de l'application illégale de marques réputées sur des montres de piètre qualité ne leur permet ni de travailler le saphir du verre 1 et de la plaquette 8 ni de procéder à des vaporisations sous vide. D'ailleurs, le coût de ces opérations, qui n'in- fluencè pas de façon sensible le prix de revient d'une montre du haut de la gamme, éuipée de toute façon d'un verre saphir biseauté, serait hors de proportion avec le prix de revient des contrefaçons inondant le marché.By itself, this mode of application of the trademark on a watch already offers the public a serious guarantee of the authenticity of the origin of the watch, because the equipment of most brown companies, which are industry the illegal application of reputable brands on poor quality watches does not allow them to work the sapphire crystal 1 and the wafer 8 or to perform vacuum sprays. Moreover, the cost of these operations, which does not significantly influence the cost price of a top-of-the-range watch, equipped in any case with a beveled sapphire crystal, would be out of proportion with the cost price of counterfeits flooding the market.

Le revers de la plaquette 8 peut encore tenir lieu de réceptacle à d'autres indications que la marque de fabrique ou de commerce, comme elle de nature à authentifier l'origine de la montre. Ainsi, l'indication 11 dans la Fig. 1, composée par exemple de lettres et de chiffres déterminés, peut constituer, en combinaison avec l'indication analogue 12, gravée sur le fond 13 du boîtier de la montre (Fig. 3), un code permettant d'individualiser chaque montre produite. Il suffit pour cela de modifier au moins l'une des indications 11, 12 d'une montre à l'autre. De cette façon, une paire déterminée d'indications 11, 12 ne se trouvera que sur une seule des montres produites. En répertoriant ces paires d'indications à l'intention des agences qui représentent la marque, celles-ci peuvent immédiatement distinguer une montre dont l'origine est authentique d'une contrefaçon.The reverse of the plate 8 can also serve as a receptacle for other indications than the trademark, such as it, to authenticate the origin of the watch. Thus, the indication 11 in FIG. 1, composed for example of specific letters and numbers, may constitute, in combination with the analogous indication 12, engraved on the bottom 13 of the watch case (Fig. 3), a code making it possible to individualize each watch produced. To do this, it suffices to modify at least one of the indications 11, 12 from one watch to another. In this way, a determined pair of indications 11, 12 will only be found on one of the watches produced. By listing these pairs of indications for the agencies that represent the brand, they can immediately distinguish a watch whose origin is authentic from a counterfeit.

Par vaporisation sous vide, il est possible de former des chiffres et des lettres très petits, qui ne sont plus lisibles à l'oeil nu. Ce moyen permet à l'acheteur de s'assurer lui-même de l'authenticité de l'origine d'une montre à l'aide d'un simple verre grossissant. Il est, en effet, pratiquement exclu que des entreprises marronnes, produisant des montres à vil prix, fassent les frais de l'équipement nécessaire à former des lettres et des chiffres de cette dimension.By vacuum spraying, it is possible to form very small numbers and letters, which are no longer readable with the naked eye. This means allows the buyer to verify for himself the authenticity of the origin of a watch using a simple magnifying glass. It is, in fact, practically impossible for brown companies, producing watches at low prices, to pay for the equipment necessary to form letters and numbers of this size.

L'application du dispositif selon l'invention n'est pas limitée aux montres rectangulaires. Il peut être utilisé avec les mêmes avantages par exemple dans le cas de montres rondes, comme le fait voir la deuxième forme d'exécution (Fig. 4 et 5). Dans ce cas, c'est une plaquette 14, également circulaire, qui est collée sur le verre rond 15 recouvrant toute la face supérieure du boîtier de Ja montre. Des indications 16, 17, de même nature que les indications 10, 11 de la première forme d'exécution, sont appliquées au revers de la plaquette 14. De préférence, cette dernière est collée dans la zone 18 du verre 15, qui est opacifiée par les éléments ornementaux 19 collés sous la périphérie du verre 15 (Fig. 5).The application of the device according to the invention is not limited to rectangular watches. It can be used with the same advantages, for example in the case of round watches, as shown in the second embodiment (Fig. 4 and 5). In this case, it is a plate 14, also circular, which is bonded to the round glass 15 covering the entire upper face of the case of the watch. Indications 16, 17, of the same nature as indications 10, 11 of the first embodiment, are applied to the reverse of the plate 14. Preferably, the latter is glued in the zone 18 of the glass 15, which is opacified by the ornamental elements 19 glued under the periphery of the glass 15 (Fig. 5).

Il n'est pas nécessaire que les dimensions de la plaquette collée sur le verre de la montre soient réduites à celles de la marque et éventuellement de l'indication chiffrée. La troisième forme d'exécution (Fig. 6 et 7) montre notamment une plaquette 20, de même forme que le verre 1 et qui est juste un peu plus petite que la face supérieure plane 2 de ce dernier. La plaquette 20 s'étend ainsi jusqu'au-dessus de la zone 21 du verre 1, qui est opacifiée par les éléments ornementaux (non représentés) que la face inférieure plane 6 du verre porte à sa périphérie. Dans cette forme d'exécution, la plaquette 20 a non seulement pour effet d'enrichir le relief du verre, en faisant apparaître celui-ci avec une face externe bien ouvrée, mais aussi celui de rehausser l'apparence des éléments ornementaux de la zone 21, en raison des réfractions produites par les biseaux 22, 23, 24 de la plaquette 20, qui s'ajoutent à celles dues aux biseaux 3, 4, 5 du verre 1, cela tout en renforçant considérablement la résistance du verre aux efforts mécaniques (pressions, chocs) qui peuvent être exercés sur lui en portant la montre régulièrement. On remarquera encore que l'encollage sans bulle et sans débordement d'une plaquette aussi grande est également de nature à éviter les contrefaçons faciles.It is not necessary that the dimensions of the plate glued to the watch glass be reduced to those of the brand and possibly of the numerical indication. The third embodiment (Fig. 6 and 7) shows in particular a plate 20, the same shape as the glass 1 and which is just a little smaller than the flat upper face 2 of the latter. The plate 20 thus extends above the zone 21 of the glass 1, which is opacified by the ornamental elements (not shown) that the planar lower face 6 of the glass carries at its periphery. In this embodiment, the plate 20 not only has the effect of enriching the relief of the glass, by making it appear with a well-worked external face, but also that of enhancing the appearance of the ornamental elements of the area. 21, due to the refractions produced by the bevels 22, 23, 24 of the wafer 20, which are added to those due to the bevels 3, 4, 5 of the glass 1, this while considerably increasing the resistance of the glass to mechanical forces (pressure, shock) that can be exerted on him by wearing the watch regularly. It will also be noted that gluing without bubbles and without overflowing of such a large plate is also likely to avoid easy counterfeiting.

La plaquette ronde 25 de la quatrième forme d'exécution (Fig. 8 et 9), collée au verre rond 15, montre qu'une plaquette de grandes dimensions est aussi utilisable dans le cas où le boîtier est rond et a sa face supérieure entièrement recouverte par le verre.The round plate 25 of the fourth embodiment (Fig. 8 and 9), glued to the round glass 15, shows that a large plate is also usable in the case where the housing is round and has its upper face entirely covered by glass.

Le verre de la montre n'est pas le seul support capable de recevoir une plaquette d'authentification telle que celles décrites dans les quatres premières formes d'exécution. Dans le cas d'un boîtier dont le bord du verre 26 est collé à demeure sur la zone interne d'un cadre 27 en métal dur, comme représenté à la Fig. 2 de la demande de brevet européen EP-A-0 064 951 de la déposante, la plaquette 8 peut être collée sur la partie du cadre 27 s'étendant au-delà du verre 26, comme le fait voir la cinquième forme d'exécution (Fig. 10 et 11).The watch glass is not the only support capable of receiving an authentication plate such as those described in the first four embodiments. In the case of a case the edge of the glass 26 of which is permanently bonded to the internal zone of a frame 27 of hard metal, as shown in FIG. 2 of European patent application EP-A-0 064 951 of the applicant, the plate 8 can be glued to the part of the frame 27 extending beyond the glass 26, as shown in the fifth embodiment (Fig. 10 and 11).

La sixième forme d'exécution (Fig. 12 et 13) montre que la même possibilité existe aussi pour la plaquette ronde 14, qui est collée sur l'anneau 28, lui-même collé sous le verre 29.The sixth embodiment (Figs. 12 and 13) shows that the same possibility also exists for the round plate 14, which is glued to the ring 28, itself glued under the glass 29.

Le fond du boîtier peut aussi tenir lieu de support à une plaquette du genre décrit précédemment. S'il est rectangulaire, comme le fond 30 de la septième forme d'exécution (Fig. 14 et 15), la plaquette 31 qu'on lui collera aura une forme s'harmonisant à celle du fond, et on collera de même une plaquette circulaire 32 sur le fond 33 d'un boîtier rond (Fig. 16 et 17).The bottom of the housing can also serve as a support for a plate of the kind described above. If it is rectangular, like the bottom 30 of the seventh embodiment (Figs. 14 and 15), the plate 31 that will be glued to it will have a shape harmonizing with that of the bottom, and we will also glue a circular plate 32 on the bottom 33 of a round housing (Figs. 16 and 17).

Dans toutes les formes d'exécution décrites, le revers de la plaquette saphir peut naturellement tenir lieu de réceptacle à des indications de nature à authentifier l'origine de la montre, telles que la marque de fabrique et/ou de commerce et/ou une indication chiffrée qui, en combinaison avec une seconde indication, également chiffrée, mais différente, appliquée sur une autre pièce visible de la montre, formera un code d'identification du producteur ou du distributeur de ces montres, individualisant chacune de celles-ci.In all of the embodiments described, the reverse of the sapphire plate can naturally serve as a receptacle for indications of a nature to authenticate the origin of the watch, such as the trademark and / or a trade mark. encrypted indication which, in combination with a second indication, also encrypted, but different, applied to another visible part of the watch, will form an identification code of the producer or distributor of these watches, individualizing each of these.

Les plaquettes d'authentification décrites peuvent aussi être collées sur d'autres matières que le saphir du verre, le métal dur du cadre ou de l'anneau apparaissant comme lunette ou l'acier du fond, par exemple sur une lunette ou un fond plaqué ou chromé ou sur des pièces en métaux précieux.The authentication plates described can also be bonded to other materials than sapphire glass, the hard metal of the frame or ring appearing as a bezel or the steel of the back, for example on a bezel or a plated back or chromed or on precious metal parts.

Bien que seules des pièces rondes et rectangulaires aient été décrites ci-dessus et représentées au dessin, il est clair que le dispositif selon l'invention peut être appliqué à n'importe quelle autre forme de pièce, polygonale à côtés rectilignes ou courbes. La forme de la plaquette d'authentification utilisée dans ces cas peut, en effet, toujours être harmonisée à celle de la montre.Although only round and rectangular parts have been described above and shown in the drawing, it is clear that the device according to the invention can be applied to any other shape of part, polygonal with straight or curved sides. The shape of the authentication plate used in these cases can, in fact, always be harmonized with that of the watch.
