Description

Domaine technique de l'inventionTechnical field of the invention

L'invention relève du domaine horloger et concerne en particulier un mouvement horloger comprenant un mécanisme de réglage de la position d'afficheurs.The invention relates to the field of watchmaking and relates in particular to a watch movement comprising a mechanism for adjusting the position of displays.

Arrière-plan technologiqueTechnological background

Les mécanismes de corrections d'une fonction d'un mouvement horloger d'une montre permettent à un utilisateur, en manipulant un organe de commande de la montre, de modifier la position d'un de ses affichages, par exemple l'heure courante.The correction mechanisms of a function of a watch movement allow a user, by manipulating a control organ of the watch, to modify the position of one of its displays, for example the current time.

Lorsque le mouvement horloger comporte plusieurs fonctions, par exemple un quantième, un second fuseau horaire, etc., leur correction respective est généralement réalisée par la tige de remontoir. En particulier, il est connu de positionner la tige de remontoir dans une position axiale particulière afin de sélectionner la fonction à corriger, et de pivoter ladite tige afin de corriger la fonction sélectionnée.When the watch movement has several functions, for example a date, a second time zone, etc., their respective correction is generally carried out by the winding stem. In particular, it is known to position the winding stem in a particular axial position in order to select the function to be corrected, and to pivot said stem in order to correct the selected function.

Au-delà d'un certain nombre de fonctions, il peut être particulièrement délicat de positionner axialement la tige de remontoir. En effet, on comprend bien qu'au-delà de trois positions axiales distinctes disponibles, il devient fastidieux de trouver la position désirée.Beyond a certain number of functions, it can be particularly tricky to position the winding stem axially. Indeed, it is understandable that beyond three distinct axial positions available, it becomes tedious to find the desired position.

Par ailleurs, lorsqu'il présente plusieurs fonctions, le mécanisme de correction est relativement complexe à réaliser puisque, dans chacune de ses positions axiales, la tige de remontoir doit être reliée cinématiquement avec des composants spécifiques du mouvement horloger afin de pouvoir agir sur une fonction donnée. En outre, l'ajout de fonctions particulières dans un mouvement horloger a pour conséquence d'augmenter les dimensions de ce dernier, puisque chaque fonction possède généralement son propre mécanisme d'entrainement.Furthermore, when it has several functions, the correction mechanism is relatively complex to produce since, in each of its axial positions, the winding stem must be kinematically connected with specific components of the watch movement in order to be able to act on a given function. In addition, the addition of specific functions in a watch movement has the consequence of increasing the dimensions of the latter, since each function generally has its own drive mechanism.

Résumé de l'inventionSummary of the invention

La présente invention vise à résoudre ces inconvénients en proposant un mouvement horloger doté de plusieurs fonctions pouvant être facilement et rapidement corrigées.The present invention aims to solve these drawbacks by proposing a watch movement equipped with several functions which can be easily and quickly corrected.

Un autre objectif de la présente invention est de simplifier le mouvement afin de minimiser ses dimensions.Another objective of the present invention is to simplify the movement in order to minimize its dimensions.

L'invention concerne à cet effet, un mouvement horloger comprenant un mobile menant cinématiquement lié à un premier et à un second mécanisme d'affichage respectivement destinés à entraîner un premier et un second afficheur d'une valeur temporelle, un mécanisme de réglage de la position de ces afficheurs comportant un baladeur et un organe de commande adapté à prendre une position de réglage dans laquelle il est en prise avec le baladeur et dans laquelle :

  • lorsqu'il est sollicité dans un premier sens de rotation, il entraîne le baladeur dans une première position de correction dans laquelle ce dernier est apte à coopérer avec le premier mécanisme d'affichage de sorte à modifier la position du premier afficheur, et
  • lorsqu'il est sollicité dans un second sens de rotation, il entraîne le baladeur dans une seconde position de correction dans laquelle ce dernier est apte à coopérer avec le second mécanisme d'affichage de sorte à modifier la position du second afficheur.
The invention relates to this end to a watch movement comprising a driving wheel set kinematically linked to a first and a second display mechanism respectively intended to drive a first and a second display of a time value, a mechanism for adjusting the position of these displays comprising a sliding gear and a control member adapted to take an adjustment position in which it is engaged with the sliding gear and in which:
  • when it is urged in a first direction of rotation, it drives the player into a first correction position in which the latter is able to cooperate with the first display mechanism so as to modify the position of the first display, and
  • when it is urged in a second direction of rotation, it drives the player into a second correction position in which the latter is able to cooperate with the second display mechanism so as to modify the position of the second display.

Le premier mécanisme d'affichage comporte un mécanisme à cliquet doté d'une roue de cliquet apte à lier cinématiquement le mobile menant et une roue d'affichage porteuse du premier afficheur de sorte à transmettre la rotation du mobile menant au premier afficheur, ladite roue de cliquet étant mobile dans un plan orthogonal à son axe de rotation lorsque l'organe de commande est sollicité pour modifier la position du premier afficheur, de sorte à interrompre la liaison cinématique entre le premier mécanisme d'affichage et le mobile menant.The first display mechanism comprises a ratchet mechanism provided with a ratchet wheel capable of kinematically connecting the driving mobile and a display wheel carrying the first display so as to transmit the rotation of the driving mobile to the first display, said ratchet wheel being movable in a plane orthogonal to its axis of rotation when the control member is requested to modify the position of the first display, so as to interrupt the kinematic connection between the first display mechanism and the driving mobile.

Ainsi, l'utilisateur peut simplement corriger une fonction du mouvement horloger en pivotant dans un sens ou dans un autre.Thus, the user can simply correct a function of the watch movement by rotating it in one direction or another.

Par ailleurs, grâce au mécanisme à cliquet, le nombre de composants du mouvement horloger est minimisé.Furthermore, thanks to the ratchet mechanism, the number of components in the watch movement is minimized.

Dans des modes particuliers de réalisation, l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises isolément ou selon toutes les combinaisons techniquement possibles.In particular embodiments, the invention may further comprise one or more of the following features, taken individually or in any technically possible combination.

Description détaillée de l'inventionDetailed description of the invention

L'invention concerne un mouvement horloger 10 destiné à être logé dans une boite de montre, et configuré pour entraîner deux afficheurs 20 et 30 de valeurs temporelles en plus d'un afficheur de l'heure courante.The invention relates to a watch movement 10 intended to be housed in a watch case, and configured to drive two displays 20 and 30 of time values in addition to a display of the current time.

Dans l'exemple préféré de réalisation de la présente invention, parmi ces deux afficheurs 20 et 30 de valeurs temporelles, un premier est un afficheur de l'heure d'un fuseau horaire additionnel à celui de l'heure courante, et un second est un afficheur de quantième.In the preferred embodiment of the present invention, among these two displays 20 and 30 of time values, a first is a display of the time of a time zone additional to that of the current time, and a second is a date display.

Pour des raisons de clarté, les composants du mouvement horloger connus de l'homme du métier ne sont pas décrits dans le présent texte et n'apparaissent pas sur les figures.For reasons of clarity, the components of the watch movement known to those skilled in the art are not described in this text and do not appear in the figures.

Les figures 1 et 2 représentent la présente invention lors de la marche normale du mouvement horloger 10, c'est-à-dire, lors de l'affichage de l'heure courante, de l'heure d'un fuseau horaire additionnel et du quantième. En particulier, la figure 1 représente le mouvement horloger 10 vue de dessus et la figure 2 représente le mouvement horloger 10 vue de dessous.THE Figures 1 and 2 represent the present invention during normal operation of the watch movement 10, that is to say, when displaying the current time, the time of an additional time zone and the date. In particular, the Figure 1 represents the watch movement 10 seen from above and the Figure 2 represents the watch movement 10 seen from below.

Le mouvement horloger 10 comprend un mobile menant 11 cinématiquement lié à un rouage de minuterie afin d'entraîner le premier et le second afficheurs 20 et 30 d'une valeur temporelle. Dans l'exemple préféré de réalisation de l'invention, le mobile menant 11 est entraîné d'un tour par jour par une roue des heures du rouage de minuterie (non représentée sur les figures).The watch movement 10 comprises a driving wheel set 11 kinematically linked to a timer train in order to drive the first and second displays 20 and 30 of a time value. In the preferred embodiment of the invention, the driving wheel set 11 is driven one revolution per day by an hour wheel of the timer train (not shown in the figures).

Le mouvement horloger 10 comporte avantageusement un mécanisme de réglage de la position de ces afficheurs 20 et 30, comprenant un baladeur 40 et un organe de commande 50 destiné adapté à prendre une position de réglage dans laquelle il est en prise avec le baladeur 40 et est apte à entraîner l'un et l'autre des premier et second afficheurs 20 et 30 en déplacement, suite à une sollicitation d'un utilisateur de la montre.The watch movement 10 advantageously comprises a mechanism for adjusting the position of these displays 20 and 30, comprising a sliding gear 40 and a control member 50 designed to take an adjustment position in which it is engaged with the sliding gear 40 and is capable of driving both of the first and second displays 20 and 30 in movement, following a request from a user of the watch.

Préférentiellement, l'organe de commande 50 est formé par une tige de remontoir liée à une couronne de remontoir et la position de réglage est matérialisée par une position axiale prédéterminée. La tige de remontoir est configurée pour être cinématiquement liée avec le baladeur 40 par l'intermédiaire d'un système de renvois connu de l'homme du métier, lorsque l'organe de commande 50 occupe la position de réglage. Un tel système de renvoi est représenté sur les figures mais n'est pas décrit en détail dans le texte car bien connu par l'homme du métier.Preferably, the control member 50 is formed by a winding stem linked to a winding crown and the adjustment position is materialized by a predetermined axial position. The winding stem is configured to be kinematically linked with the sliding gear 40 by means of a return system known to those skilled in the art, when the control member 50 occupies the adjustment position. Such a return system is shown in the figures but is not described in detail in the text because it is well known to those skilled in the art.

Comme le montrent les figures, le baladeur 40 comporte une roue d'entraînement 41 par laquelle il est apte à être entraîné en rotation par l'organe de commande 50, par l'intermédiaire du système de renvois.As shown in the figures, the sliding gear 40 comprises a drive wheel 41 by which it is capable of being driven in rotation by the control member 50, via the transmission system.

Le baladeur 40 est engagé dans un chemin de guidage de manière libre en rotation et en translation le long d'une direction orthogonale à la direction selon laquelle il est libre de pivoter. Ainsi, le baladeur 40 est apte à occuper deux positions extrêmes dans ledit chemin de guidage. Le chemin de guidage n'est pas représenté sur les figures pour des raisons de clarté et est par exemple formé par une saignée traversante réalisée dans une structure support du mouvement horloger 10, tel qu'un pont ou une platine. Le baladeur 40 est entraîné dans l'une ou l'autre de ces positions extrêmes par l'organe de commande 50, lorsqu'il occupe la position de réglage, selon le sens de rotation dans lequel ce dernier est sollicité. Ces positions extrêmes sont appelées « positions de correction » dans la suite du texte.The sliding gear 40 is engaged in a guide path freely in rotation and translation along a direction orthogonal to the direction in which it is free to pivot. Thus, the sliding gear 40 is able to occupy two extreme positions in said guide path. The guide path is not shown in the figures for reasons of clarity and is for example formed by a through groove made in a support structure of the watch movement 10, such as a bridge or a plate. The sliding gear 40 is driven into one or other of these extreme positions by the control member 50, when it occupies the adjustment position, depending on the direction of rotation in which the latter is urged. These extreme positions are called “correction positions” in the remainder of the text.

En particulier, lorsqu'il est positionné dans la position de réglage par un utilisateur et qu'il est sollicité dans un premier sens de rotation, l'organe de commande 50 est configuré pour entraîner le baladeur 40 dans une première position de correction dans laquelle ce dernier est apte à coopérer avec le premier mécanisme d'affichage 200 de sorte à modifier la position du premier afficheur 20.In particular, when it is positioned in the adjustment position by a user and it is urged in a first direction of rotation, the control member 50 is configured to drive the slider 40 into a first correction position in which the latter is able to cooperate with the first display mechanism 200 so as to modify the position of the first display 20.

Comme visible sur les figures, le premier mécanisme d'affichage 200 comporte un mécanisme à cliquet 210 configuré pour permettre la liaison cinématique entre le mobile menant 11 et ledit premier mécanisme d'affichage 200 lorsque l'organe de commande 50 n'est pas sollicité, et pour interrompre cette liaison cinématique lorsque l'organe de commande 50 est sollicité.As visible in the figures, the first display mechanism 200 comprises a ratchet mechanism 210 configured to allow the kinematic connection between the driving mobile 11 and said first display mechanism 200 when the control member 50 is not activated, and to interrupt this kinematic connection when the control member 50 is activated.

Plus précisément, le mécanisme à cliquet 210 est doté d'une roue de cliquet 211 apte à lier cinématiquement le mobile menant 11 et une roue d'affichage 21 porteuse du premier afficheur 20 de sorte à transmettre la rotation du mobile menant 11 au premier afficheur 20, comme l'illustrent les flèches sur la figure 1. En outre, la roue de cliquet 211 est mobile en translation dans un plan orthogonal à son axe de rotation ou en rotation autour de l'axe du mobile menant 11, lorsque l'organe de commande 50 est sollicité dans le premier sens de rotation lorsqu'il est en position de réglage, de sorte à interrompre la liaison cinématique entre le premier mécanisme d'affichage 200 et le mobile menant 11. Cette caractéristique permet d'éviter d'endommager le mouvement horloger 10 en transmettant des efforts au rouage de finissage et à l'oscillateur.More specifically, the ratchet mechanism 210 is provided with a ratchet wheel 211 capable of kinematically linking the driving mobile 11 and a display wheel 21 carrying the first display 20 so as to transmit the rotation of the driving mobile 11 to the first display 20, as illustrated by the arrows on the Figure 1 . In addition, the ratchet wheel 211 is movable in translation in a plane orthogonal to its axis of rotation or in rotation around the axis of the driving wheel 11, when the control member 50 is urged in the first direction of rotation when it is in the adjustment position, so as to interrupt the kinematic connection between the first display mechanism 200 and the driving wheel 11. This characteristic makes it possible to avoid damaging the watch movement 10 by transmitting forces to the finishing gear and to the oscillator.

Dans l'exemple préféré de réalisation de l'invention, le mécanisme à cliquet 210 est doté d'une roue de cliquet 211 engrenant avec une roue menante 110 du mobile menant 11 et avec la roue d'affichage 21. La roue menante 110, la roue de cliquet 211 et la roue d'affichage 21 sont inscrites dans un même plan, comme visible sur les figures, de sorte à minimiser l'épaisseur du mouvement horloger 10, tout en permettant de réduire le nombre de composants du mouvement horloger.In the preferred embodiment of the invention, the ratchet mechanism 210 is provided with a ratchet wheel 211 meshing with a driving wheel 110 of the driving wheel set 11 and with the display wheel 21. The driving wheel 110, the ratchet wheel 211 and the display wheel 21 are inscribed in the same plane, as visible in the figures, so as to minimize the thickness of the watch movement 10, while making it possible to reduce the number of components of the watch movement.

Avantageusement, le mécanisme à cliquet 210 peut comprendre un organe de rappel 212 solidaire de la roue de cliquet 211 de sorte à la contraindre vers une position de butée dans laquelle elle est engrenée avec la roue menante 110 et avec la roue d'affichage 21. Dans l'exemple de réalisation représenté sur les figures, l'organe de rappel 212 est configuré pour assurer le maintien de la position axiale de la roue de cliquet 211 et est agencé de sorte à appliquer une force de rappel sur un axe de la roue de cliquet 211. Alternativement, l'organe de rappel 212 peut être agencé en appui contre la denture de la roue de cliquet 211 pour minimiser encore l'épaisseur du mouvement. L'organe de rappel 212 est alors en effet situé dans le même plan que la roue menante 110, la roue de cliquet 211 et la roue d'affichage 21.Advantageously, the ratchet mechanism 210 may comprise a return member 212 secured to the ratchet wheel 211 so as to force it towards a stop position in which it is meshed with the driving wheel 110 and with the display wheel 21. In the exemplary embodiment shown in the figures, the return member 212 is configured to ensure the maintenance of the axial position of the ratchet wheel 211 and is arranged so as to apply a return force to an axis of the ratchet wheel 211. Alternatively, the return member 212 may be arranged to bear against the teeth of the ratchet wheel 211 to further minimize the thickness of the movement. The return member 212 is then in fact located in the same plane as the driving wheel 110, the ratchet wheel 211 and the display wheel 21.

En résumé, la roue de cliquet 211 est adaptée à transmettre un mouvement de la roue menante 110 jusqu'à la roue d'affichage 21 et à interdire la transmission du mouvement de la roue d'affichage 21 jusqu'à la roue menante 110. Le fonctionnement du mécanisme à cliquet 210 est décrit en détail dans la suite du texte.In summary, the ratchet wheel 211 is adapted to transmit a movement from the driving wheel 110 to the display wheel 21 and to prohibit the transmission of the movement from the display wheel 21 to the driving wheel 110. The operation of the ratchet mechanism 210 is described in detail in the remainder of the text.

Dans l'exemple préféré de réalisation de l'invention, la roue d'affichage 21 est formée par une roue de fuseau horaire. Le premier mécanisme d'affichage 200 comporte une roue de transmission 22 reliant cinématiquement la roue d'affichage 21 et le baladeur 40 lorsque l'organe de commande 50 est dans la position de réglage et est sollicité dans le premier sens de rotation.In the preferred embodiment of the invention, the display wheel 21 is formed by a time zone wheel. The first display mechanism 200 comprises a transmission wheel 22 kinematically connecting the display wheel 21 and the sliding gear 40 when the control member 50 is in the adjustment position and is biased in the first direction of rotation.

Plus précisément, comme visible sur la vue de détail de droite sur la figure 3, le baladeur 40 comporte une première roue de réglage 42 reliée cinématiquement à la roue de transmission 22 lorsque l'organe de commande 50 est dans la position de réglage et qu'il est sollicité dans le premier sens de rotation. La roue de transmission 22 entraîne alors la roue d'affichage 21 en rotation, qui déplace l'afficheur de l'heure d'un fuseau horaire additionnel. La vue de détail de gauche sur la figure 3 montre que, lors de cette rotation, la roue d'affichage 21 entraîne la roue de cliquet 211 à rouler autour de la roue menante 110 et à se désengager de la roue d'affichage 21. En particulier, lors de la rotation de la roue d'affichage 21, la denture de cette dernière exerce un couple sur la denture de la roue de cliquet 211 déplaçant la roue de cliquet 211 de sorte à dégager lesdites dentures l'une de l'autre, c'est-à-dire que les dents de la roue de cliquet 211 ne sont plus en contact avec celles de la roue d'affichage 21.More precisely, as visible on the right detail view on the Figure 3 , the player 40 comprises a first adjustment wheel 42 kinematically connected to the transmission wheel 22 when the control member 50 is in the adjustment position and is urged in the first direction of rotation. The transmission wheel 22 then drives the display wheel 21 in rotation, which moves the time display by an additional time zone. The left-hand detail view on the Figure 3 shows that, during this rotation, the display wheel 21 causes the ratchet wheel 211 to roll around the drive wheel 110 and to disengage from the display wheel 21. In particular, during the rotation of the display wheel 21, the teeth of the latter exert a torque on the teeth of the ratchet wheel 211 moving the ratchet wheel 211 so as to disengage said teeth from each other, that is to say that the teeth of the ratchet wheel 211 are no longer in contact with those of the display wheel 21.

Si le mécanisme à cliquet 210 comprend un organe de rappel 212, le couple exercé sur la denture de la roue de cliquet 211 va à l'encontre de la force de rappel exercée par l'organe de rappel 212 sur ladite roue de cliquet 211. La roue de cliquet 211 est donc immédiatement ramenée au contact de la roue d'affichage 21, en position de butée, à la suite du dégagement des dentures de la roue de cliquet 211 et de la roue d'affichage 21.If the ratchet mechanism 210 comprises a return member 212, the torque exerted on the teeth of the ratchet wheel 211 counteracts the return force exerted by the return member 212 on said ratchet wheel 211. The ratchet wheel 211 is therefore immediately brought back into contact with the display wheel 21, in the stop position, following the disengagement of the teeth of the ratchet wheel 211 and the display wheel 21.

Dans l'exemple de réalisation de l'invention représenté sur les figures, la roue de cliquet 211 roule donc, à la manière d'un satellite, sur la roue menante 110 lors de la rotation de la roue d'affichage 21 en se déplaçant dans un mouvement de va-et-vient.In the exemplary embodiment of the invention shown in the figures, the ratchet wheel 211 therefore rolls, like a satellite, on the drive wheel 110 during rotation of the display wheel 21 by moving in a back-and-forth movement.

Alternativement ou en addition, la roue de cliquet 211 peut être engagée dans un chemin de guidage, de manière analogue au baladeur 40, de sorte à guider la roue de cliquet 211 en déplacement lorsque le baladeur 40 est sollicité dans le premier sens de rotation. Par exemple, la structure de guidage peut être configurée pour guider la roue de cliquet 211 en rotation selon un axe passant par le centre du mobile menant 11 ou en translation selon une trajectoire rectiligne tangentielle à un cercle concentrique au mobile menant 11.Alternatively or in addition, the ratchet wheel 211 may be engaged in a guide path, in a manner analogous to the slider 40, so as to guide the ratchet wheel 211 in movement when the slider 40 is urged in the first direction of rotation. For example, the guide structure may be configured to guide the ratchet wheel 211 in rotation along an axis passing through the center of the driving mobile 11 or in translation along a rectilinear path tangential to a circle concentric with the driving mobile 11.

Tel qu'illustré sur la figure 4, lorsqu'il occupe la position de réglage et qu'il est sollicité dans un second sens de rotation, l'organe de commande 50 est configuré pour entraîner le baladeur 40 dans une seconde position de correction dans laquelle ce dernier est apte à modifier la position du second afficheur 30 par le biais d'un second mécanisme d'affichage 300.As illustrated on the Figure 4 , when it occupies the adjustment position and is urged in a second direction of rotation, the control member 50 is configured to drive the slider 40 into a second correction position in which the latter is capable of modifying the position of the second display 30 by means of a second display mechanism 300.

Il y a lieu de noter que, lorsqu'il occupe la première position, le baladeur 40 est en prise avec la roue d'affichage 21, comme décrit précédemment, et est désolidarisé du second mécanisme d'affichage 300, tel que représenté sur la figure 3. À l'inverse, lorsqu'il occupe la seconde position, le baladeur 40 est en prise avec le second mécanisme d'affichage 300 et est désolidarisé de la roue d'affichage 21, tel que représenté sur la figure 4.It should be noted that, when it occupies the first position, the slider 40 is engaged with the display wheel 21, as previously described, and is disengaged from the second display mechanism 300, as shown in the Figure 3 Conversely, when it occupies the second position, the slider 40 is engaged with the second display mechanism 300 and is detached from the display wheel 21, as shown in the Figure 4 .

Le baladeur 40 comporte une seconde roue de réglage 43 par laquelle il est apte à être relié cinématiquement avec le second mécanisme d'affichage 300. Cette seconde roue de réglage 43 est constituée par une came comportant au moins un doigt de correcteur, par exemple trois, comme représenté sur les figures. La roue d'entraînement 41 et les première et seconde roues de réglage 42 et 43 sont agencées de manière coaxiale.The player 40 comprises a second adjustment wheel 43 by which it is capable of being kinematically connected to the second display mechanism 300. This second adjustment wheel 43 is constituted by a cam comprising at least one corrector finger, for example three, as shown in the figures. The drive wheel 41 and the first and second adjustment wheels 42 and 43 are arranged coaxially.

En particulier, dans l'exemple préféré de réalisation de la présente invention, et tel que visible sur la vue de détail de la figure 4, le second mécanisme d'affichage 300 comporte une denture 301 liée au second afficheur 30, constitué ici par un disque de quantième. Le doigt de correcteur est apte à coopérer avec la denture 301 de sorte à entraîner le second afficheur 30 dans une rotation séquentielle lors de la rotation dudit baladeur 40 grâce à l'indexation faite par un ressort de sautoir 213 disposé sous l'organe de rappel 212, lorsque le baladeur 40 est dans la seconde position de correction.In particular, in the preferred embodiment of the present invention, and as seen in the detail view of the Figure 4 , the second display mechanism 300 comprises a toothing 301 linked to the second display 30, constituted here by a date disc. The corrector finger is able to cooperate with the toothing 301 so as to drive the second display 30 in a sequential rotation during the rotation of said player 40 thanks to the indexing made by a jumper spring 213 arranged under the return member 212, when the player 40 is in the second correction position.

Dans l'exemple préféré de réalisation de l'invention, le mobile menant 11 comprend un doigt d'entraînement 111 apte à coopérer avec la denture 301 du second mécanisme d'affichage 300 pour entraîner le second afficheur 30 dans une rotation séquentielle d'un pas, à chaque tour réalisé par ledit mobile menant 11, comme visible sur la figure 1.In the preferred embodiment of the invention, the driving wheel 11 comprises a drive finger 111 capable of cooperating with the teeth 301 of the second display mechanism 300 to drive the second display 30 in a sequential rotation of one step, for each revolution made by said driving wheel 11, as visible on the Figure 1 .

Ce doigt d'entraînement 111 peut comporter un système de sécurité, comme visible en détail sur la figure 2, bien connu de l'homme du métier et permettant audit doigt d'entraînement 111 de s'escamoter afin de ne pas transmettre de mouvement de rotation au mobile menant 11 lorsque le second afficheur 30 est entraîné par le baladeur 40, pour ne pas dérégler l'afficheur de fuseau.This training finger 111 may include a safety system, as seen in detail on the Figure 2 , well known to those skilled in the art and allowing said drive finger 111 to retract so as not to transmit rotational movement to the driving wheel 11 when the second display 30 is driven by the sliding gear 40, so as not to disrupt the time zone display.

De manière plus générale, il est à noter que les modes de mise en oeuvre et de réalisation considérés ci-dessus ont été décrits à titre d'exemples non limitatifs, et que d'autres variantes sont par conséquent envisageables.More generally, it should be noted that the methods of implementation and embodiment considered above have been described as non-limiting examples, and that other variants are consequently conceivable.
