Description

La présente invention concerne un dispositif indicateur de réserve de marche agencé pour être intégré dans une masse oscillante pour mouvement à remontage automatique, ledit dispositif comportant des moyens d'affichage de la réserve de marche par comparaison avec des moyens d'affichage complémentaires, lesdits moyens d'affichage et moyens d'affichage complémentaires étant intégrés dans ladite masse oscillante.The present invention relates to a power reserve indicator device arranged to be integrated in an oscillating weight for self-winding movement, said device comprising means for displaying the power reserve in comparison with complementary display means, said means display and complementary display means being integrated in said oscillating weight.

L'invention concerne encore une masse oscillante pour montre à remontage automatique, comportant un tel dispositif de réserve de marche.The invention also relates to an oscillating weight for a self-winding watch, comprising such a power reserve device.

L'invention concerne encore une montre à remontage automatique comportant une masse oscillante dont les mouvements sont transmis à un ressort de barillet de ladite montre, ladite masse oscillante comportant un tel dispositif indicateur de réserve de marche.The invention also relates to a self-winding watch comprising an oscillating weight whose movements are transmitted to a mainspring of said watch, said oscillating mass comprising such a power reserve indicator device.

L'invention concerne le domaine des montres à remontage automatique.The invention relates to the field of self-winding watches.

Dans une montre à remontage automatique, les mouvements du porteur sont transmis au ressort de barillet par l'intermédiaire d'une masse oscillante et d'un rouage de démultiplication.In a self-winding watch, the movements of the wearer are transmitted to the mainspring by means of an oscillating weight and a reduction gear train.

Le rouage d'un mécanisme de remontage automatique se compose d'éléments dentés qui permettent de transmettre la force depuis la masse oscillante jusqu'au rochet et d'armer le ressort de barillet. En amont du rochet, ce rouage de mécanisme de remontage automatique comporte usuellement, d'une part un train de renvoi composé du pignon de la masse oscillante et de mobiles intermédiaires redresseurs de sens, et d'autre part un rouage réducteur, agencé pour réduire la vitesse initiale de la masse oscillante et à accroître la force destinée à l'armage du ressort de barillet.The gear of an automatic winding mechanism consists of toothed elements that transmit the force from the oscillating mass to the ratchet and arm the barrel spring. Upstream of the ratchet, this wheel of automatic winding mechanism usually comprises, on the one hand, a gear train composed of the pinion of the mass oscillating and intermediate rectifiers sense, and secondly a gear train, arranged to reduce the initial speed of the oscillating weight and increase the force for winding the mainspring.

Une complication utile et appréciée sur les montres à remontage automatique est l'affichage de la réserve de marche, qui est assuré par un dispositif indicateur de réserve de marche, permettant à tout moment à l'utilisateur de connaître le potentiel de marche normale, dans les meilleures conditions de fiabilité et de précision du ressort de barillet. De façon connue, la réserve de marche est indiquée soit par une indication graduée, chiffrée ou graphique sur un disque visible à travers un guichet, soit par le positionnement d'une aiguille face à un cadran portant une telle indication.A useful and appreciated complication on self-winding watches is the display of the power reserve, which is provided by a power reserve indicator device, allowing the user at any time to know the normal walking potential, in the best conditions of reliability and precision of the mainspring. In known manner, the power reserve is indicated either by a graduated, encrypted or graphic indication on a disc visible through a window, or by the positioning of a needle facing a dial bearing such an indication.

L'indication de la réserve de marche se doit d'être compatible avec le faible espace encore disponible dans une pièce d'horlogerie comportant plusieurs complications. Sa fiabilité doit être exemplaire, et en particulier pour dissuader l'utilisateur d'effectuer un remontage manuel de complément alors même que le ressort de barillet est déjà complètement armé.The indication of the power reserve must be compatible with the small space still available in a timepiece with several complications. Its reliability must be exemplary, and in particular to dissuade the user from performing a manual winding complement even though the mainspring is already fully armed.

Les contraintes de service des montres à remontage automatique sont élevées, car on estime qu'un mécanisme de remontage automatique est soumis à plusieurs millions de mouvements chaque année.The service constraints of self-winding watches are high because it is estimated that an automatic winding mechanism is subject to several million movements each year.

La contrainte de gain de place dans une montre amène à rechercher l'utilisation du volume de la masse oscillante elle-même pour loger certaines fonctionnalités, notamment l'indicateur de réserve de marche. Mais les contraintes de service évoquées ci-dessus ont généralement détourné les constructeurs d'une telle utilisation de la masse oscillante.The space saving constraint in a watch leads to seeking the use of the volume of the oscillating mass itself to house certain functionalities, in particular the power reserve indicator. But the service constraints mentioned above have generally diverted manufacturers from such use of the oscillating weight.

Le document de brevet CH 301 497 divulgue une montre à remontage automatique comprenant une masse oscillante dont les mouvements sont transmis à un ressort de barillet de la montre, cette montre comprenant également un dispositif indicateur de réserve de marche comportant des moyens d'affichage de la réserve de marche.The patent document CH 301 497 discloses a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, this watch also comprising a reserve indicator device of step comprising means for displaying the power reserve.

On connaît encore, par le document de brevet EP 1 826 633 , une montre à remontage automatique comprenant une masse oscillante dont les mouvements sont transmis à un ressort de barillet de la montre, cette montre comprenant également un dispositif indicateur de réserve de marche comprenant des moyens d'affichage de la réserve de marche, qui sont montés sur la masse oscillante.It is still known from the patent document EP 1 826 633 , a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, this watch also comprising a power reserve indicator device comprising means for displaying the power reserve, which are mounted on the oscillating weight.

L'invention se propose de fournir une solution au problème de la réalisation d'un mécanisme d'affichage de la réserve de marche intégré à la masse oscillante, qui soit fiable, simple à mettre en oeuvre, et d'une grande robustesse.The invention proposes to provide a solution to the problem of producing a mechanism for displaying the power reserve integrated with the oscillating weight, which is reliable, simple to implement, and of great robustness.

A cet effet, la présente invention concerne un dispositif indicateur de réserve de marche agencé pour être intégré dans une masse oscillante pour mouvement à remontage automatique, ledit dispositif comportant des moyens d'affichage de la réserve de marche par comparaison avec des moyens d'affichage complémentaires, lesdits moyens d'affichage et moyens d'affichage complémentaires étant intégrés dans ladite masse oscillante, caractérisé en ce que lesdits moyens d'affichage et moyens d'affichage complémentaires sont montés mobiles en rotation synchrone, à un instant donné, par rapport à ladite masse oscillante.For this purpose, the present invention relates to a power reserve indicator device arranged to be integrated in an oscillating weight for self-winding movement, said device comprising means for displaying the power reserve compared with display means. complementary, said display means and complementary display means being integrated in said oscillating mass, characterized in that said display means and complementary display means are mounted movably in synchronous rotation, at a given instant, with respect to said oscillating weight.

Selon une autre caractéristique de l'invention, ledit dispositif comporte un mécanisme d'affichage différentiel à friction à deux entrées, l'une fixe et l'autre mobile, et à une sortie constituée par un organe d'affichage comportant lesdits moyens d'affichage et moyens d'affichage complémentaires, ladite entrée mobile entraînant lesdits moyens d'affichage, et ladite entrée fixe entraînant lesdits moyens d'affichage complémentaires par des moyens d'entraînement débrayables.According to another characteristic of the invention, said device comprises a differential friction display mechanism with two inputs, one fixed and the other mobile, and an output constituted by a display member comprising said means for display and complementary display means, said moving input driving said display means, and said fixed input driving said complementary display means by disengageable drive means.

Selon une autre caractéristique de l'invention, lesdits moyens d'affichage complémentaire comportent une butée, sur laquelle lesdits moyens d'affichage sont agencés pour coopérer en appui dans une position dite de fin d'armage, et en ce que ladite entrée fixe coopère avec un accouplement débrayable, qui est embrayé avec lesdits moyens d'affichage complémentaires quand lesdits moyens d'affichage ne sont pas en appui sur ladite butée, et qui est débrayé desdits moyens d'affichage complémentaires quand lesdits moyens d'affichage sont en appui sur ladite butée.According to another characteristic of the invention, said complementary display means comprise a stop, on which said display means are arranged to cooperate in support in a so-called end-of-arming position, and in that said fixed input co-operates with a disengageable coupling, which is engaged with said complementary display means when said display means are not supported on said stop, and which is disengaged from said complementary display means when said display means are supported on said stop.

Selon une autre caractéristique de l'invention, ladite position dite de fin d'armage correspond à la fin d'armage d'un ressort de barillet auquel est raccordée ladite entrée mobile par l'intermédiaire d'un rouage.According to another characteristic of the invention, said so-called end of winding position corresponds to the end of winding of a barrel spring to which said movable inlet is connected by means of a gear train.

L'invention concerne encore une masse oscillante pour montre à remontage automatique, comportant un tel dispositif de réserve de marche.The invention also relates to an oscillating weight for a self-winding watch, comprising such a power reserve device.

L'invention concerne encore une montre à remontage automatique comportant une masse oscillante dont les mouvements sont transmis à un ressort de barillet que comporte ladite montre, ladite masse oscillante comportant un tel dispositif indicateur de réserve de marche.The invention also relates to a self-winding watch comprising an oscillating mass whose movements are transmitted to a mainspring of the watch, said oscillating weight comprising such a power reserve indicator device.

Ainsi, la présente invention procure une pièce d'horlogerie à remontage automatique comprenant un dispositif indicateur de réserve de marche dont le mécanisme d'affichage de la réserve de marche est porté par la masse oscillante. La simplicité et la compacité de l'invention rendent son utilisation particulièrement avantageuse.

L'invention concerne le domaine des montres à remontage automatique à masse oscillante. L'invention se propose de fournir une solution au problème de la réalisation d'un mécanisme d'affichage de la réserve de marche intégré à la masse oscillante, qui soit fiable, simple à mettre en oeuvre, et robuste.The invention relates to the field of self-winding watches with oscillating weight. The invention proposes to provide a solution to the problem of producing a mechanism for displaying the power reserve integrated with the oscillating weight, which is reliable, simple to implement, and robust.

Une masse oscillante 1 oscille dans un mouvement de pivotement autour d'un axe de pivotement D1, généralement mais non obligatoirement situé au centre du mouvement de la montre dans laquelle la masse oscillante est installée. Cette montre comporte classiquement un ressort de barillet auquel sont transmis les mouvements de la masse oscillante 1 pour son remontage. L'invention s'applique indifféremment à une masse oscillante 1 située au-dessous ou au-dessus du mouvement de la montre, celle-ci n'étant pas représentée sur les figures par souci de simplification.An oscillating mass 1 oscillates in a pivoting movement about a pivot axis D1, generally but not necessarily located at the center of the movement of the watch in which the oscillating weight is installed. This watch conventionally comprises a barrel spring to which are transmitted the movements of the oscillating mass 1 for its reassembly. The invention applies equally to an oscillating weight 1 located below or above the movement of the watch, the latter not being shown in the figures for the sake of simplification.

L'invention concerne un dispositif indicateur de réserve de marche 100 agencé pour être intégré dans une masse oscillante 1 pour mouvement à remontage automatique.The invention relates to a power reserve indicator device 100 arranged to be integrated in an oscillating weight 1 for self-winding movement.

Ce dispositif 100 comporte des moyens d'affichage 20 de la réserve de marche par comparaison avec des moyens d'affichage complémentaires 30, par exemple respectivement une aiguille 2 et un cadran 3. Ces moyens d'affichage 20 et moyens d'affichage complémentaires 30 sont intégrés dans la masse oscillante 1.This device 100 comprises display means 20 of the power reserve by comparison with complementary display means 30, for example respectively a needle 2 and a dial 3. These display means 20 and complementary display means 30 are integrated in the oscillating mass 1.

Selon l'invention, aussi bien les moyens d'affichage 20 que les moyens d'affichage complémentaires 30 sont montés mobiles en rotation par rapport à la masse oscillante 1. Cette rotation est synchrone à un instant donné, c'est-à-dire que les moyens d'affichage 20 occupent une position angulaire instantanée particulière par rapport aux moyens d'affichage complémentaires 30 en fonction du potentiel restant du ressort de barillet à l'instant considéré, mais cette position angulaire relative de l'un par rapport à l'autre n'est pas dépendante des mouvements imprimés par l'utilisateur à la masse oscillante, car, selon l'invention, au décalage angulaire d'affichage de la réserve de marche près, les moyens d'affichage 20 et les moyens d'affichage complémentaires 30 sont en rotation synchrone par rapport à la masse oscillante 1.According to the invention, both the display means 20 and the complementary display means 30 are rotatably mounted relative to the oscillating mass 1. This rotation is synchronous at a given instant, that is to say that the display means 20 occupy a particular instantaneous angular position relative to the complementary display means 30 as a function of the remaining potential of the mainspring at the instant in question, but this relative angular position of the one with respect to the other is not dependent on the movements printed by the user to the oscillating weight, because, according to the invention, the angular shift of the power reserve display near, the display means 20 and the means of complementary displays 30 are in synchronous rotation with respect to the oscillating mass 1.

Dans un mode de réalisation préféré, tel que visible sur les figures, les moyens d'affichage 20 et les moyens d'affichage complémentaires 30 sont montés mobiles en rotation par rapport à un axe de rotation commun D2.In a preferred embodiment, as visible in the figures, the display means 20 and the complementary display means 30 are rotatably mounted relative to a common axis of rotation D2.

La présente invention est illustrée avec des moyens d'affichage 20 de l'indication de réserve de marche constitués par une aiguille 2, qui coopèrent avec des moyens d'affichage complémentaires 30 constitués par un cadran 3. Il va de soi que cet exemple est donné à titre purement illustratif et non limitatif, et que l'invention peut s'appliquer de manière analogue à une indication de la réserve de marche au moyen de la coopération de plusieurs cadrans, ou encore de plusieurs aiguilles, ou autre.The present invention is illustrated with display means 20 of the power reserve indication constituted by a needle 2, which cooperate with complementary display means 30 constituted by a dial 3. It goes without saying that this example is given purely for illustrative and not limiting, and that the invention can be applied in a similar manner to an indication of the power reserve by means of the cooperation of several dials, or more needles, or other.

De façon innovante, le dispositif 100 selon l'invention comporte un mécanisme d'affichage différentiel à friction à deux entrées, l'une fixe et l'autre mobile, et à une sortie :

  • l'entrée fixe entraîne les moyens d'affichage complémentaires 30 par des moyens d'entraînement débrayables ;
  • l'entrée mobile entraîne les moyens d'affichage 20 par des moyens non débrayables ;
  • la sortie est constituée par un organe d'affichage comportant ces moyens d'affichage 20 et ces moyens d'affichage complémentaires 30.
In an innovative manner, the device 100 according to the invention comprises a differential friction display mechanism with two inputs, one fixed and the other mobile, and at an exit:
  • the fixed input drives the complementary display means 30 by disengageable drive means;
  • the moving input drives the display means 20 by non-disengageable means;
  • the output is constituted by a display member comprising these display means 20 and these complementary display means 30.

Tel que visible sur les figures 2 et 3, le mécanisme différentiel d'affichage comporte un roulement à billes 13, dont la cage intérieure porte la masse oscillante 1 par l'intermédiaire d'une vis 14, et dont la cage extérieure, d'une part porte une roue fixe 8 constituant cette entrée fixe, et d'autre part sert d'appui en rotation à une roue mobile 4 constituant cette entrée mobile.As visible on the Figures 2 and 3 , the differential display mechanism comprises a ball bearing 13, whose inner race carries the oscillating weight 1 by means of a screw 14, and whose outer cage, on the one hand carries a fixed wheel 8 constituting this fixed input, and secondly serves as support in rotation to a movable wheel 4 constituting this movable input.

Les moyens d'affichage complémentaire 30 comportent une butée 16. Les moyens d'affichage 20 sont agencés pour coopérer en appui sur cette butée 16 dans une position dite de fin d'armage. Cette position dite de fin d'armage correspond à la fin d'armage du ressort de barillet, auquel l'entrée mobile est raccordée par l'intermédiaire d'un rouage. L'entrée fixe coopère avec un accouplement débrayable, qui est embrayé avec les moyens d'affichage complémentaires 30 quand les moyens d'affichage 20 ne sont pas en appui sur la butée 16, et qui est débrayé des moyens d'affichage complémentaires 30 quand les moyens d'affichage 20 sont en appui sur cette butée 16. Tel que visible sur la figure 3, le cadran 3 comporte une telle butée 16, qui est solidaire de ce cadran 3. Dans une réalisation préférée, visible sur les figures 2 et 3, mais nullement limitative, cet accouplement débrayable comporte une roue à friction 10. Celle-ci est solidarisée aux moyens d'affichage complémentaires 30 sous l'action de moyens de rappel élastique quand les moyens d'affichage 20 ne sont pas en appui sur la butée 16, et est débrayée des moyens d'affichage complémentaires 30 quand les moyens d'affichage 20 sont en appui sur cette dernière. L'entrée fixe, notamment la roue fixe 8, coopère avec la roue à friction 10, laquelle est agencée pour être solidarisée au cadran 3, sous l'action d'un clinquant 11 constituant ces moyens de rappel élastique, quand l'aiguille 2 n'est pas en appui sur la butée 16, et à être débrayée du cadran 3, quand l'aiguille 2 est en appui sur la butée 16. de ce fait, quand l'aiguille 2 arrive en butée contre l'applique en armage complet tend à pousser le cadran 3. Le clinquant 11 permet l'entraînement de la roue à friction 10 en fonctionnement normal, c'est-à-dire pendant l'armage ou le désarmage, et le débrayage en fin d'armage. On comprend que la friction permet le débrayage du système, ce qui permet d'éviter tout dommage de celui-ci.The complementary display means 30 comprise a stop 16. The display means 20 are arranged to cooperate in abutment on this stop 16 in a so-called end of weaving position. This so-called end of winding position corresponds to the end of winding of the mainspring, to which the movable inlet is connected via a gear train. The fixed input cooperates with a disengageable coupling, which is engaged with the complementary display means 30 when the display means 20 are not in abutment on the stop 16, and which is disengaged from the complementary display means 30 when the display means 20 bear on this stop 16. As visible on the figure 3 , the dial 3 comprises such a stop 16, which is integral with this dial 3. In a preferred embodiment, visible on the Figures 2 and 3 , but in no way limiting, this disengageable coupling comprises a friction wheel 10. This is secured to the complementary display means 30 under the action of elastic return means when the display means 20 are not supported on the stop 16, and is disengaged from the complementary display means 30 when the display means 20 are supported on the latter. The fixed input, in particular the fixed wheel 8, cooperates with the wheel friction 10, which is arranged to be secured to the dial 3, under the action of a foil 11 constituting these elastic return means, when the needle 2 is not in abutment on the stop 16, and to be disengaged of the dial 3, when the needle 2 is in abutment on the stop 16. as a result, when the needle 2 comes into abutment against the full armature applique tends to push the dial 3. The foil 11 allows the training friction wheel 10 in normal operation, that is during arming or disarming, and disengagement at the end of arming. It is understood that the friction allows the disengagement of the system, which avoids any damage thereof.

En effet, si on se réfère au cas particulier illustré sur les figures avec une aiguille 2 coopérant avec un cadran 3, lors de la rotation en pivotement de la masse oscillante 1, le cadran 3 et l'aiguille 2 tournent en sens inverse de la masse oscillante 1. Par construction, comme il sera exposé ci-dessous, le rapport est de 1 entre les différents rouages, de ce fait, le cadran 3 et l'aiguille 2 tournent en sens inverse de la masse oscillante 1 mais à la même vitesse, en rotation synchrone à un instant donné, donnant à l'utilisateur l'impression que le cadran 3 et l'aiguille 2 ne tournent pas lorsque la masse oscillante 1 tourne. Bien sûr, l'aiguille 2 a une mobilité relative par rapport au cadran 3, en fonction du potentiel du ressort de barillet : pendant le fonctionnement normal, lors de l'armage ou du désarmage du ressort de barillet, la résultante arrive sur la roue mobile 4 qui constitue l'entrée mobile, et permet un décalage angulaire de l'aiguille 2 par rapport au cadran 3, visualisant ainsi le potentiel de réserve de marche.Indeed, if one refers to the particular case illustrated in the figures with a needle 2 cooperating with a dial 3, during the pivotal rotation of the oscillating mass 1, the dial 3 and the needle 2 turn in the opposite direction of the oscillating weight 1. By construction, as will be explained below, the ratio is 1 between the different wheels, therefore, the dial 3 and the needle 2 turn in the opposite direction of the oscillating weight 1 but at the same speed, in synchronous rotation at a given moment, giving the user the impression that the dial 3 and the needle 2 do not turn when the oscillating weight 1 rotates. Of course, the needle 2 has a relative mobility with respect to the dial 3, depending on the potential of the mainspring: during normal operation, during the winding or disarming of the mainspring, the resultant arrives on the wheel mobile 4 which constitutes the movable input, and allows an angular offset of the needle 2 relative to the dial 3, thus visualizing the power reserve potential.

Par contre, en fin d'armage du ressort de barillet, l'aiguille 2 vient en appui sur la butée 16 du cadran 3, ce qui oblige ce dernier à frictionner sur la roue de friction 10, et à se décaler à la même vitesse que l'aiguille 2.On the other hand, at the end of the winding of the mainspring, the needle 2 bears on the abutment 16 of the dial 3, which forces the latter to rub on the friction wheel 10, and to shift at the same speed than the needle 2.

Pour obtenir simplement un rapport de 1 entre les rouages, et garantir la synchronisation entre l'aiguille 2 et le cadran 3, on choisit avantageusement la roue mobile 4 et la roue fixe 8 avec le même nombre de dents.To simply obtain a ratio of 1 between the workings, and ensure the synchronization between the needle 2 and the dial 3, is advantageously chosen the movable wheel 4 and the fixed wheel 8 with the same number of teeth.

La roue mobile 4 entraîne, par une roue de renvoi intermédiaire 5, une roue d'indicateur 6 qui est solidaire, de préférence par l'intermédiaire d'un axe d'indicateur 15, des moyens d'affichage 20, notamment de l'aiguille 2.The moving wheel 4 drives, by means of an intermediate idler wheel 5, an indicator wheel 6 which is secured, preferably via an indicator pin 15, to the display means 20, in particular to the needle 2

La roue fixe 8 entraîne, par l'intermédiaire d'une roue de renvoi intermédiaire 9, la roue à friction 10, laquelle est montée libre en rotation sur un axe 12 solidaire des moyens d'affichage complémentaires 30, notamment le cadran 3.The fixed wheel 8 drives, via an intermediate return wheel 9, the friction wheel 10, which is mounted free to rotate on an axis 12 secured to the complementary display means 30, in particular the dial 3.

De façon préférée, la roue à friction 10 et la roue d'indicateur 6 ont le même nombre de dents que la roue mobile 4 et que la roue fixe 8, et les roues de renvoi intermédiaires 5 et 9 qui font la liaison entre l'affichage et le centre du mouvement, sont identiques entre elles.Preferably, the friction wheel 10 and the indicator wheel 6 have the same number of teeth as the moving wheel 4 and the fixed wheel 8, and the intermediate wheels 5 and 9 which make the connection between the display and the center of the movement, are identical to each other.

Une plaque 18 fixée à la masse oscillante 1 comporte des paliers de reprise des roues de renvoi 5 et 9, ainsi que de l'axe d'indicateur 5.A plate 18 fixed to the oscillating mass 1 comprises bearings for the return wheels 5 and 9, as well as the indicator shaft 5.

L'invention concerne encore une masse oscillante 1 pour montre à remontage automatique, comportant un tel dispositif indicateur de réserve de marche 100.The invention also relates to an oscillating weight 1 for a self-winding watch, comprising such a power reserve indicator device 100.

L'invention concerne encore une montre à remontage automatique comportant une masse oscillante 1 dont les mouvements sont transmis à un ressort de barillet que comporte cette montre, cette masse oscillante 1 comportant un tel dispositif indicateur de réserve de marche 100.The invention also relates to a self-winding watch comprising an oscillating weight 1 whose movements are transmitted to a mainspring of this watch, this oscillating mass 1 comprising such a power reserve indicator device 100.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. En particulier, il peut être envisagé d'intercaler des roues de renvoi intermédiaires pour peu que les rapports d'engrenage soient égaux et de signes opposés, et que le rapport entre les différents rouages du mécanisme différentiel d'affichage soit maintenu égal à 1.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims. In particular, it may be envisaged interposing intermediate return wheels as long as the gear ratios are equal and of opposite signs, and that the ratio between the different wheels of the differential display mechanism is maintained equal to 1.
