A lower annular display board (30) is partially covered by the board (28) in a display zone and is visible through a transparent or open sector of the board (28) in the zone, where the boards (28, 30) are shared in regular sectors. Lower, intermediate and upper wheels kinematically connect a driving wheel (10) and the boards in a sequential manner, so that two of the display boards are not simultaneously driven.

Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie mécanique et concerne, plus particulièrement, un dispositif d'affichage du quantième, du type grande date. Ces derniers, afin de permettre une lecture aisée du quantième, proposent des digits de taille importante.The present invention relates to the field of mechanical watchmaking and more particularly relates to a display device of the date, the type of large date. These, in order to allow an easy reading of the date, offer large digits.

Pour ne pas occuper une trop grande surface du cadran et ainsi laisser un espace suffisant au niveau du cadran pour d'autres indicateurs, de tels dispositifs comprennent des moyens d'affichage de la dizaine du quantième et de l'unité du quantième distincts. Une roue d'entraînement entraînée par un mouvement horloger à raison d'un pas par jour, est reliée cinématiquement de manière séquentielle aux moyens d'affichage des dizaines et des unités afin d'afficher le quantième dans une zone déterminée.In order not to occupy too large a surface of the dial and thus leave sufficient space at the dial for other indicators, such devices include means for displaying the ten or so different date and date units. A driving wheel driven by a watch movement at a rate of one step per day, is kinematically connected sequentially to the display means tens and units to display the date in a given area.

Etat de la techniqueState of the art

On connaît de nombreux mécanismes permettant d'afficher le quantième avec des indicateurs séparés pour les dizaines et pour les unités. Certains, tel que celui proposé dans le document CH 32703 , proposent d'afficher la dizaine du quantième au moyen d'un disque et l'unité au moyen d'un anneau disposé concentriquement autour du disque, de manière à ce que les indications portées par le disque et par l'anneau apparaissent côte à côte dans une zone d'affichage. D'autres, tel que celui proposé dans le document CH310559 , proposent d'afficher la dizaine et l'unité du quantième au moyen d'un disque, la distance entre les deux points de pivot des disques étant légèrement supérieure à la somme de leur rayon, de manière à ce que les indications portées par chaque disque apparaissent l'une à côté de l'autre dans une zone d'affichage située sur une ligne reliant les deux points de pivot.Numerous mechanisms are known for displaying the date with separate indicators for tens and for units. Some, such as the one proposed in the document CH 32703 , propose to display the decade of the date by means of a disc and the unit by means of a ring concentrically arranged around the disc, so that the indications carried by the disc and by the ring appear side by side. coast in a display area. Others, such as the one proposed in the document CH310559 , propose to display the ten and the unit of the date by means of a disc, the distance between the two points of pivot of the discs being slightly greater than the sum of their radius, so that the indications carried by each disc appear next to each other in a display area on a line connecting the two pivot points.

Même si ces dispositifs permettent déjà d'utiliser des digits d'une taille importante, l'augmentation de la taille de ces indications oblige à augmenter également la taille des disques et anneau mis en oeuvre. Selon le type et la taille du mouvement dans lequel le dispositif est monté, les éléments d'affichage doivent occuper un espace raisonnable qui définit la limite de l'augmentation de la taille des digits.Even if these devices already allow to use digits of a large size, increasing the size of these indications requires to also increase the size of the disks and ring implemented. Depending on the type and size of the movement in which the device is mounted, the elements display must occupy a reasonable space that defines the limit of increasing the size of the digits.

Par ailleurs, on connaît du document CH 1920208 , une pièce d'horlogerie électromécanique dans laquelle l'unité du quantième est affichée au moyen de deux disques superposés. Le disque supérieur est muni d'une ouverture rendant visible le disque inférieur et les digits sont répartis entre les deux planches.Moreover, we know of the document CH 1920208 , an electromechanical timepiece in which the date unit is displayed by means of two superposed disks. The upper disk is provided with an opening making visible the lower disk and the digits are distributed between the two boards.

Bien qu'intéressant, ce dispositif ne peut être appliqué directement à une montre mécanique. En effet, les éléments d'affichage sont généralement entraînés par une roue de 31, c'est-à-dire munie de 31 dents, avançant d'un pas par jour, afin que l'indication du quantième soit modifiée une fois par jour, aux environs de minuit (de manière sautante ou trainante). Si l'on dispose les digits 0 à 9 de la manière proposée dans le document, cela signifie que la roue de 31 doit faire avancer les disques supérieurs et inférieurs, comprenant chacun 6 secteurs (0, 1, 1, 2, 3, vide et 4, 5, 6, 7, 8, 9), de 60° par pas. Or, selon les dimensions des composants de la montre, il n'est pas toujours possible d'obtenir des sauts de cette amplitude en utilisant un entraînement conventionnel et un sautoir. En outre, le mécanisme proposé dans le document cité étant entraîné par un moteur électrique, il n'est absolument pas tenu compte des problèmes liés à l'utilisation d'une source d'énergie mécanique. Il est en effet important que le dispositif perturbe le moins possible la marche du mouvement et, particulièrement, ne modifie pas l'amplitude de l'organe régulateur.Although interesting, this device can not be applied directly to a mechanical watch. Indeed, the display elements are generally driven by a wheel 31, that is to say provided with 31 teeth, advancing one step per day, so that the indication of the date is changed once a day around midnight (jumping or trapping). If digits 0 to 9 are available in the manner proposed in the document, this means that the wheel 31 must advance the upper and lower disks, each comprising 6 sectors (0, 1, 1, 2, 3, empty and 4, 5, 6, 7, 8, 9), 60 ° in steps. However, depending on the size of the components of the watch, it is not always possible to obtain jumps of this amplitude using a conventional drive and jumper. In addition, the mechanism proposed in the cited document being driven by an electric motor, it is absolutely ignored problems related to the use of a source of mechanical energy. It is indeed important that the device disturbs the movement as little as possible and, in particular, does not modify the amplitude of the regulating member.

La présente invention a pour but de proposer un dispositif d'affichage du quantième permettant d'utiliser des digits de taille supérieure à ceux utilisés dans les affichage de type grande de l'état de la technique, tout en étant particulièrement adapté à une montre mécanique.The object of the present invention is to provide a date display device making it possible to use digits of larger size than those used in the large type of displays of the state of the art, while being particularly suitable for a mechanical watch. .

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

On a représenté sur la figure 1 les éléments essentiels d'un dispositif d'affichage du quantième, destiné à être entraîné par un mouvement de montre mécanique qui lui, ne figure pas au dessin. L'énergie fournie par le mouvement est transmise au dispositif par une roue d'entraînement 10, comprenant 31 dents régulièrement réparties et couramment appelée roue de 31. Cette roue effectue un pas par jour, aux environs de minuit. Le pas peut se faire de manière sautante, semi-trainante ou trainante. L'homme du métier sait parfaitement comment obtenir ce type de mobile et de mouvement. A titre d'exemple, un mécanisme d'entraînement de type sautant 11 est visible sur la figure 2. Etant de type conventionnel, ce mécanisme d'entraînement ne sera pas décrit plus en détail. On notera que les différents éléments mentionnés ci-après sont montés sur des ponts et/ou des platines du mouvement de base ou d'un module additionnel, non représentés pour clarifier les dessins.We have shown on the figure 1 the essential elements of a date display device, intended to be driven by a mechanical watch movement which is not shown in the drawing. The energy provided by the movement is transmitted to the device by a drive wheel 10, comprising 31 teeth regularly distributed and commonly called wheel 31. This wheel takes one step per day, around midnight. The step can be jumping, semi-trapping or dragging. The skilled person knows perfectly how to get this type of mobile and movement. For example, a jump type drive mechanism 11 is visible on the figure 2 . Being of conventional type, this drive mechanism will not be described in more detail. Note that the various elements mentioned below are mounted on bridges and / or plates of the basic movement or an additional module, not shown to clarify the drawings.

La roue 10 est positionnée par un sautoir 12. Elle est solidaire en rotation avec une première roue inférieure 14, une deuxième roue intermédiaire 16 et un troisième roue supérieure 18, montées coaxiales à la roue 10. Les roues 14, 16 et 18 sont taillées sur le nombre 31, mais certaines de leurs dents manquent, comme détaillé ci-après.The wheel 10 is positioned by a jumper 12. It is integral in rotation with a first lower wheel 14, a second intermediate wheel 16 and a third upper wheel 18, mounted coaxial with the wheel 10. The wheels 14, 16 and 18 are cut on the number 31, but some of their teeth are missing, as detailed below.

Les roues 14, 16 et 18 coopèrent respectivement avec un pignon inférieur 20, un pignon intermédiaire 22 et un pignon supérieur 24, visibles sur la figure 2. Ces pignons sont montés coaxiaux sur un arbre 25 et sont chacun positionné par un sautoir. Plus particulièrement, le pignon 20 est doté d'un canon 20a se terminant à un premier niveau. Le pignon 22 est superposé au pignon 20 et comprend également un canon 22a disposé à l'extérieur du canon 20a et se terminant à un deuxième niveau, inférieur au premier niveau. Le pignon 24 est superposé au pignon 22 et comprend un canon 24a disposé à l'extérieur du canon 22a et se terminant à un troisième niveau, inférieur au deuxième niveau. Les pignons sont chacun positionnés par un sautoir 27.The wheels 14, 16 and 18 cooperate respectively with a lower gear 20, an intermediate gear 22 and an upper gear 24, visible on the figure 2 . These gears are mounted coaxially on a shaft 25 and are each positioned by a jumper. More particularly, the pinion 20 has a barrel 20a ending at a first level. The pinion 22 is superimposed on the pinion 20 and also comprises a barrel 22a disposed outside the barrel 20a and ending at a second level, lower than the first level. The pinion 24 is superimposed on the pinion 22 and comprises a barrel 24a disposed outside the barrel 22a and ending at a third level, lower than the second level. The gables are each positioned by a jumper 27.

Une première planche 26, circulaire dans l'exemple illustré, est fixée à l'extrémité du canon 20a. Elles portent, régulièrement réparties à son pourtour, des représentations des digits 0, 1, 2, 3, destinés à afficher le chiffre des dizaines du quantième. Il est évident que divers types de symboles peuvent être utilisés pour représenter ces digits. Le 0 peut même être remplacé par un simple trait ou par un vide, constituant une représentation du 0.A first board 26, circular in the example shown, is attached to the end of the barrel 20a. They carry, regularly distributed at its periphery, representations of digits 0, 1, 2, 3, intended to display the number of tens of the date. It is obvious that various types of symbols can be used to represent these digits. The 0 can even be replaced by a simple line or by a vacuum, constituting a representation of 0.

Une deuxième planche 28, d'apparence annulaire dans l'exemple illustré, est fixée à l'extrémité du canon 22a. Elle est dimensionnée de manière à être ajustée autour de la planche 26, c'est-à-dire que le diamètre intérieur de l'anneau est légèrement supérieur au diamètre de la planche 26. Comme le montre la figure 4 et de manière avantageuse, le profil de la planche 28 peut être déterminé de manière à ce qu'elle soit située au même niveau que la planche 26. Dans la variante illustrée, la planche est divisée en huit secteurs et le pignon 22 comporte 8 dents. La planche porte les représentations des digits 0, 1, 2, 3 et 4 et trois secteurs ouverts (notés v1, v2 et v3 ci-après). Autrement dit, l'anneau présente un diamètre intérieur constant et une première portion de 5/8ème de tour avec un premier diamètre extérieur, les digits étant disposés régulièrement sur cette portion, et une deuxième portion de 3/8ème de tour avec un deuxième diamètre extérieur réduit, de manière à définir une ouverture d'environ 135°. On notera que les secteurs ouverts peuvent aussi être des secteurs transparents, le disque étant alors complet, mais 3/8ème de l'anneau étant transparents. Ceci peut être simplement réalisé par des métallisations. Une telle solution présente l'avantage d'avoir un disque équilibré.A second board 28, of annular appearance in the example shown, is attached to the end of the barrel 22a. It is dimensioned so as to be adjusted around the board 26, that is to say that the inside diameter of the ring is slightly greater than the diameter of the board 26. As shown in FIG. figure 4 and advantageously, the profile of the board 28 can be determined so that it is located at the same level as the board 26. In the variant shown, the board is divided into eight sectors and the pinion 22 has 8 teeth . The plate carries the representations of digits 0, 1, 2, 3 and 4 and three open sectors (noted v1, v2 and v3 below). In other words, the ring has a constant inner diameter and a first portion of 5 / 8th of a turn with a first outer diameter, the digits being regularly arranged on this portion, and a second portion of 3 / 8th of a turn with a second diameter. outside, so as to define an opening of about 135 °. It will be noted that the open sectors can also be transparent sectors, the disk being then complete, but 3/8 th of the ring being transparent. This can be simply achieved by metallizations. Such a solution has the advantage of having a balanced disk.

Une troisième planche 30, d'apparence annulaire dans l'exemple illustré, est fixée à l'extrémité du canon 24a et prend donc place à un niveau inférieur par rapport à la planche 28. Le diamètre extérieur de la planche 30 est sensiblement égal à celui de la planche 28. Dans la variante illustrée, la planche est divisée en huit secteurs et le pignon 24 comporte 8 dents. La planche porte les représentations des digits 5, 6, 7, 8 et 9 et trois secteurs passifs (notés v1, v2 et v3 ci-après), c'est-à-dire sans inscription. Ces secteurs peuvent être ouverts, transparents ou non ou comporter n'importe quelle inscription, comme on le comprendra ci-après, ils n'ont pas de fonction dans l'affichage. Le profil de la planche 30 est ajusté à celui de la planche 28 de sorte que les deux planches soient le plus proche possible l'une de l'autre, particulièrement au niveau des zones portant les digits.A third plate 30, of annular appearance in the example shown, is fixed to the end of the barrel 24a and therefore takes place at a lower level with respect to the board 28. The outer diameter of the board 30 is substantially equal to that of the board 28. In the variant illustrated, the board is divided into eight sectors and the pinion 24 has 8 teeth. The plate carries the representations of digits 5, 6, 7, 8 and 9 and three passive sectors (noted v1, v2 and v3 below), that is to say without registration. These sectors can be open, transparent or not or include any registration, as will be understood below, they have no function in the display. The profile of the board 30 is adjusted to that of the board 28 so that the two boards are as close as possible to one another, particularly at the areas bearing the digits.

Dans l'exemple proposé, la planche 28 est disposée au niveau de la planche 26, la planche 30 étant disposée à un niveau inférieur. Il serait également possible de disposer la planche 30 au niveau de la planche 26, la planche 28 étant disposée à un niveau supérieur. De préférence, l'une des deux planches 28 et 30 est située dans le plan de la planche 26, afin de n'avoir un affichage que sur deux niveaux différents pour les trois disques.In the proposed example, the board 28 is disposed at the board 26, the board 30 being disposed at a lower level. It would also be possible to have the board 30 at the board 26, the board 28 being disposed at a higher level. Preferably, one of the two boards 28 and 30 is located in the plane of the board 26, to have a display on two different levels for the three discs.

Une vis 32 coopérant avec un filetage ménagé à l'intérieur de l'arbre 25 maintient en position l'ensemble des pignons et des planches.A screw 32 cooperating with a thread formed inside the shaft 25 holds in position all the gears and boards.

Comme mentionné ci-dessus et ainsi que le montre la figure 3, les roues 14, 16 et 18 comportent des portions dépourvues de dents et constituent ainsi des moyens de comptage, permettant d'afficher le quantième correct et de relier cinématiquement de manière séquentielle la roue d'entraînement et les première, deuxième et troisième planches d'affichage.As mentioned above and as shown in figure 3 the wheels 14, 16 and 18 comprise portions without teeth and thus constitute counting means for displaying the correct date and kinematically connecting sequentially the drive wheel and the first, second and third boards d display.

Selon un premier mode de réalisation, la roue inférieure 14, pour l'entraînement de la première planche 26, c'est-à-dire de la planche des dizaines, comporte 4 dents. Plus précisément, la roue présente successivement, à sa périphérie, un secteur sans denture, correspondant à l'angle qu'occuperaient 8 dents, 1 dent, un secteur sans denture, correspondant à l'angle qu'occuperaient 9 dents, 1 dent, un secteur sans denture, correspondant à l'angle qu'occuperaient 9 dents, 1 dent, un secteur sans denture, correspondant à l'angle qu'occuperaient 1 dent et 1 dent.According to a first embodiment, the lower wheel 14, for driving the first board 26, that is to say, the tens board has 4 teeth. More precisely, the wheel has successively, at its periphery, a sector without teeth, corresponding to the angle that would occupy 8 teeth, 1 tooth, a sector without teeth, corresponding to the angle that would occupy 9 teeth, 1 tooth, a sector without teeth, corresponding to the angle that would occupy 9 teeth, 1 tooth, a sector without teeth, corresponding to the angle that would occupy 1 tooth and 1 tooth.

La roue 16 entraînant la deuxième planche 28, c'est-à-dire la planche portant les digits 5 à 9, comporte 24 dents. Plus précisément, la roue 16 présente successivement, à sa périphérie, 6 dents, un secteur sans denture, correspondant à l'angle qu'occuperaient 2 dents, 8 dents, un secteur sans denture, correspondant à l'angle qu'occuperaient 2 dents, 8 dents, un secteur sans denture, correspondant à l'angle qu'occuperaient 2 dents, 2 dents, un secteur sans denture, correspondant à l'angle qu'occuperait 1 dent.The wheel 16 driving the second board 28, that is to say the board bearing the digits 5 to 9, has 24 teeth. More specifically, the wheel 16 has successively, at its periphery, 6 teeth, a sector without teeth, corresponding to the angle that would occupy 2 teeth, 8 teeth, a sector without teeth, corresponding to the angle that would occupy 2 teeth , 8 teeth, a sector without teeth, corresponding to the angle that would occupy 2 teeth, 2 teeth, a sector without teeth, corresponding to the angle that would occupy 1 tooth.

La roue 18 entraînant la troisième planche 28, c'est-à-dire la planche portant les digits 0 à 4, comporte également 24 dents. Plus précisément, la roue 18 présente successivement, à sa périphérie, 4 dents, un secteur sans denture, correspondant à l'angle qu'occuperaient 2 dents, 4 dents, un secteur sans denture, correspondant à l'angle qu'occuperait 1 dent, 4 dents, un secteur sans denture, correspondant à l'angle qu'occuperait 1 dent, 4 dents, un secteur sans denture, correspondant à l'angle qu'occuperait 1 dent, 4 dents, un secteur sans denture, correspondant à l'angle qu'occuperait 1 dent, 4 dents, un secteur sans denture, correspondant à l'angle qu'occuperait 1 dent.The wheel 18 driving the third board 28, that is to say the board bearing digits 0 to 4, also has 24 teeth. More specifically, the wheel 18 has successively, at its periphery, 4 teeth, a sector without teeth, corresponding to the angle that would occupy 2 teeth, 4 teeth, a sector without teeth, corresponding to the angle that would occupy 1 tooth , 4 teeth, a sector without teeth, corresponding to the angle that would occupy 1 tooth, 4 teeth, a sector without teeth, corresponding to the angle that would occupy 1 tooth, 4 teeth, a sector without teeth, corresponding to the angle that would occupy 1 tooth, 4 teeth, a sector without teeth, corresponding to the angle that would occupy 1 tooth.

Ces trois roues 16, 18 et 20 sont coordonnées de manière à ce que les planches 26, 28 et 30 effectuent les mouvements suivants. Dans les colonnes av.

Pour faciliter le montage des roues 14, 16 et 18 et permettre qu'elles soient correctement positionnées les unes par rapport aux autres afin d'avoir une bonne coordination des entraînements, les roues comportent avantageusement des moyens d'indexation. Ceux-ci peuvent être constitués par une encoche 34 ou trou disposé sur chacune des roues, les encoches ou trous étant alignés lorsque les trois roues sont correctement positionnées.To facilitate the mounting of the wheels 14, 16 and 18 and allow them to be correctly positioned relative to each other in order to have a good coordination of the drives, the wheels advantageously comprise indexing means. These may be constituted by a notch 34 or hole disposed on each of the wheels, the notches or holes being aligned when the three wheels are correctly positioned.

Afin de perturber le moins possible le fonctionnement du mouvement, les moyens de comptage 14, 16 et 18 sont agencés de manière à n'entraîner simultanément, au plus, que deux des trois planches.In order to disturb as little as possible the operation of the movement, the counting means 14, 16 and 18 are arranged so as to simultaneously drive, at most, only two of the three boards.

L'exemple donné ci-dessus à propos des dentures des roues 14, 16 et 18 et de la répartition des digits n'est pas le seul qui permette de n'entraîner qu'une ou deux des trois planches. Ainsi, toujours en partageant les planches en 8 secteurs, l'homme du métier peut, par exemple, disposer les digits 0 à 5 (et deux secteurs ouverts) ou 0 à 6 (et un secteur ouvert) sur la planche 28, tandis que les digits 6 à 9 (avec 4 secteurs passifs) ou, respectivement, 7 à 9 (avec 5 secteurs passifs), sont disposés sur la planche 30.The example given above about the teeth of the wheels 14, 16 and 18 and the distribution of digits is not the only one that allows to drive only one or two of the three boards. Thus, still sharing the boards in 8 sectors, the skilled person may, for example, have digits 0 to 5 (and two open sectors) or 0 to 6 (and an open sector) on the board 28, while digits 6 to 9 (with 4 passive sectors) or, respectively, 7 to 9 (with 5 passive sectors), are arranged on the board 30.

Il est également possible de partager les planches en 9 secteurs, en disposant les digits 0 à 5 et 3 secteurs ouverts sur la planche 26 et les digits 6 à 9 et 5 secteurs passifs sur la planche 28.It is also possible to share the boards in 9 sectors, with the digits 0 to 5 and 3 open sectors on the board 26 and the digits 6 to 9 and 5 passive sectors on the board 28.

Les exemples ci-dessus ne sont ni exhaustifs, ni limitatifs. Ainsi, il est également envisageable d'intercaler les secteurs passifs ou ouverts dans une série de chiffre ou de disposer les premiers digits, c'est-à-dire à partir de 0, sur la planche 30 et non pas sur la planche 28. Il suffit simplement d'adapter les dentures des moyens de comptage.The above examples are neither exhaustive nor limiting. Thus, it is also possible to insert the passive or open sectors in a series of numbers or to have the first digits, that is to say starting from 0, on the board 30 and not on the board 28. It suffices simply to adapt the teeth of the counting means.

Il est même possible que les planches 26 et 28 soient divisées en un nombre différent de secteurs. On pourrait ainsi avoir 8 secteurs sur l'une et 9 sur l'autre, le nombre de dents des pignons et des moyens de comptage étant évidemment adapté en conséquence. En outre, il est également réalisable de ne pas disposer les chiffres de manière consécutive sur une même planche, c'est-à-dire que l'homme du métier peut disposer les digits 0, 1, 2, 3 et 5 sur l'une des planches et les autres sur l'autre.It is even possible that boards 26 and 28 are divided into a different number of sectors. One could thus have 8 sectors on one and 9 on the other, the number of teeth of the gears and counting means being obviously adapted accordingly. In addition, it is also feasible to do not arrange the figures consecutively on the same board, that is to say that the skilled person can arrange the digits 0, 1, 2, 3 and 5 on one of the boards and the others on the 'other.

L'invention peut aussi être appliquée à un dispositif d'affichage du quantième dans lequel la planche portant les indications des dizaines et celles portant les indications des unités ne sont pas concentriques, à l'instar de l'enseignement du document CH 310559 cité ci-dessus. Dans une première variante, les planches des unités sont concentriques, seule la planche des dizaines pivotant en un deuxième point. Dans une deuxième variante, l'une des planches des unités est concentrique à la planche des dizaines, comme dans le mode de réalisation préféré, seule l'autre planche des unités pivote en un deuxième point. Dans cette variante, les deux planches des unités se superposent au moins dans une zone d'affichage de manière à afficher l'unité du quantième à côté de la dizaine.The invention can also be applied to a date display device in which the board bearing the indications of tens and those bearing the indications of the units are not concentric, like the teaching of the document. CH 310559 Cited above. In a first variant, the boards of the units are concentric, only the board of the dozens pivoting in a second point. In a second variant, one of the boards of the units is concentric with the board of tens, as in the preferred embodiment, only the other board of the units pivots to a second point. In this variant, the two boards of the units are superimposed at least in a display area so as to display the date unit next to the ten.

Le dispositif qui vient d'être décrit peut parfaitement s'adapter aux mécanismes de correction rapide connus de l'homme du métier, tel que le représente la figure 1 sous la référence 36. On peut distinguer un mobile de correction 38 entraîné par un organe de commande non représenté et actionnable par le porteur de la montre pour entraîner en rotation le mobile de correction. Ce mobile porte des doigts 40 destinés à coopérer avec la roue d'entraînement 10 pour effectuer une correction. En fonctionnement normal, c'est-à-dire lorsqu'aucune correction n'est effectuée, un sautoir 42 agit sur les doigts de manière à les maintenir en dehors du chemin de la denture de la roue d'entraînement.The device which has just been described can perfectly adapt to the rapid correction mechanisms known to those skilled in the art, as represented by FIG. figure 1 under reference 36. A correction wheel 38 can be distinguished driven by a control member not shown and operable by the wearer of the watch to rotate the correction mobile. This mobile carries fingers 40 intended to cooperate with the drive wheel 10 to make a correction. In normal operation, that is to say when no correction is made, a jumper 42 acts on the fingers so as to keep them out of the way of the toothing of the drive wheel.

Il est à noter que l'homme du métier pourra agencer le dispositif qui vient d'être décrit dans le calibre de base ou dans un module additionnel.It should be noted that those skilled in the art will be able to arrange the device which has just been described in the basic template or in an additional module.
