Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne plus particulièrement une montre électronique comportant un dispositif d'affichage de quantième.The present invention relates to the field of watchmaking. It relates more particularly to an electronic watch comprising a date display device.

ART ANTÉRIEURPRIOR ART

Il est connu de réaliser des montres comportant l'affichage du quantième, c'est-à-dire le numéro d'ordre du jour courant dans le mois. Cet affichage est réalisé d'une façon classique à l'aide d'un disque annulaire rotatif sur lequel sont inscrits les numéros de un à trente-et-un. Le disque de quantième est placé sous le cadran dans lequel est ménagé un guichet laissant apparaitre le quantième du jour courant. Le mécanisme de la montre entraine le disque en rotation au passage d'un jour à l'autre afin d'incrémenter le quantième d'une unité. Le retour à un à la fin d'un mois comportant moins de 31 jours est effectué manuellement ou automatiquement.It is known to make watches comprising the display of the date, that is to say, the order number of the current day in the month. This display is made in a conventional manner using a rotating annular disk on which are inscribed the numbers from one to thirty-one. The date disc is placed under the dial in which is formed a window letting appear the date of the current day. The mechanism of the watch causes the rotating disc to pass from one day to the next in order to increment the date of a unit. The return to one at the end of a month with less than 31 days is done manually or automatically.

De façon alternative le quantième peut être indiqué à l'aide d'une aiguille pivotante. Pour cela, les numéros du quantième sont inscrits au moins partiellement sur le cadran au niveau du tour d'heure ou sur un cadran annexe. On connaît par exemple la demande de brevet EP 0617346 qui décrit une montre possédant un chronographe muni selon les cas d'une grande ou d'une petite aiguille de seconde. Sur demande, l'aiguille de seconde peut être réaffectée à la désignation du quantième lorsque le chronographe n'est pas utilisé. Dans le cas où la grande aiguille de seconde est réaffectée à l'affichage du quantième, les numéros de un à trente-et-un sont marqués sur le tour d'heure.Alternatively the date can be indicated using a pivoting needle. For this, the date numbers are inscribed at least partially on the dial at the turn of the hour or on a dial schedule. For example, the patent application is known EP 0617346 which describes a watch having a chronograph provided with the case of a large or a small second hand. On request, the second hand can be reassigned to the date designation when the chronograph is not used. In case the big needle of second is reassigned to the date display, the numbers from one to thirty-one are marked on the hour turn.

On connait également la demande WO94/03845 qui décrit une montre électronique possédant un affichage du quantième réalisé à l'aide de deux cadrans annexes dont les aiguilles indiquent la dizaine et l'unité du quantième.We also know the demand WO94 / 03845 which describes an electronic watch having a date display made with two auxiliary dials whose hands indicate the ten and the date unit.

On connaît également les documents EP 2 562 609 A1 et WO 2005/091086 A1 qui décrivent des montres électroniques ayant une aiguille des heures et une aiguille des minutes montées coaxiales et entraînées indépendamment l'une de l'autre par des moteurs.The documents are also known EP 2 562 609 A1 and WO 2005/091086 A1 which describe electronic watches having an hour hand and minute hand mounted coaxially and driven independently of each other by motors.

Enfin, on connaît le document FR 2 404 250 , qui décrit une montre électronique dans laquelle les aiguilles des heures et minutes sont entraînées par un seul moteur. La montre comporte un mode de fonctionnement dans lequel le quantième est affiché par l'aiguille des minutes, laquelle, suite à l'appui sur un bouton poussoir par l'utilisateur, se déplace d'abord vers le repère "D" (date) et en suite vers la valeur numérique (en minutes) représentant la date courante.Finally, we know the document FR 2 404 250 , which describes an electronic watch in which the hour and minute hands are driven by a single motor. The watch includes an operating mode in which the date is displayed by the minute hand, which, following the pressing of a push button by the user, first moves towards the "D" mark (date) and then to the numeric value (in minutes) representing the current date.

Cependant, les différents types connus d'affichage du quantième présentent plusieurs inconvénients. L'affichage par un disque rotatif ou par des cadrans à aiguilles dédiés nécessite de développer des pièces et des mécanismes spécifiques ce qui rend ces montres plus complexes à développer et à fabriquer et augmente leur encombrement. Dans les cas d'un affichage par aiguille, les inscriptions du quantième portées directement sur le cadran surchargent celui-ci et rendent la lecture des indications horaires confuse. Quel que soit le type d'affichage du quantième, le nombre d'informations à afficher impose une taille de caractère réduite ce qui nuit à la lisibilité en particulier pour les montres de petite dimension. Pour y remédier, certaines montres avec affichage du quantième dans un guichet prévoient une loupe grossissante sur la glace, solution peu esthétique et de surcroit onéreuse. Par ailleurs, les dispositifs connus pour l'affichage du quantième demandent des moyens d'affichage ou des marquages spécifiques, incompatibles avec une montre au design épuré.However, the different known types of date display have several disadvantages. Display by a rotating disk or by dedicated needle dials requires the development of specific parts and mechanisms which makes these watches more complex to develop and manufacture and increases their bulk. In the case of a display by hand, the inscriptions of the date worn directly on the dial overload it and make the reading of the hourly indications confused. Whatever the type of date display, the number of information to display imposes a reduced character size which affects readability especially for small watches. To remedy this, some watches with date display in a window provide a magnifying lens on the ice, unsightly and expensive solution. Moreover, the known devices for displaying the date require specific display means or markings, incompatible with a watch design sleek.

RÉSUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention a pour but de remédier à ces différents inconvénients en proposant une montre électronique avec affichage de quantième plus simple à fabriquer, plus lisible et avec une esthétique améliorée.The present invention aims to remedy these different disadvantages by offering an electronic watch with date display easier to manufacture, more legible and with improved aesthetics.

De façon plus précise, l'invention concerne une montre électronique comportant un dispositif d'affichage comprenant un cadran horaire, une première aiguille et une deuxième aiguille pivotantes de façon coaxiale, entrainées indépendamment par deux organes moteurs et indiquant dans un premier mode d'affichage pour l'une, l'heure, et pour l'autre, les minutes du temps courant en référence à leurs positions respectives sur le cadran horaire. De façon originale, la montre comporte en outre un organe de commande apte à activer un deuxième mode d'affichage dans lequel les première et deuxième aiguilles sont positionnées en référence au cadran horaire de façon à indiquer respectivement la dizaine et l'unité du quantième.More specifically, the invention relates to an electronic watch comprising a display device comprising a clock face, a first needle and a second needle pivoting coaxially, driven independently by two driving members and indicating in a first display mode for one, the hour, and the other, the minutes of the current time with reference to their respective positions on the time dial. In an original way, the watch furthermore comprises a control member capable of activating a second display mode in which the first and second hands are positioned with reference to the hour dial so as to respectively indicate the ten and the date unit.

Cet agencement offre un moyen compact et peu onéreux d'afficher le quantième sans avoir à développer des moyens d'affichage spécifiques supplémentaires. Il améliore également la lisibilité de l'information, spécialement pour les montres de petit format. Enfin, en se passant de moyens d'affichage ou de marquage supplémentaires, il permet d'obtenir une montre à l'esthétique épurée.This arrangement provides a compact and inexpensive means of displaying the date without having to develop additional specific display means. It also improves the legibility of the information, especially for small watches. Lastly, by dispensing with additional display or marking means, it makes it possible to obtain a watch with a refined aesthetic.

  • the figure 2 represents a second embodiment,
  • the figure 3 represents the dial of a watch according to a third embodiment.

DESCRIPTION DÉTAILLÉEDETAILED DESCRIPTION

La figure 1 représente une montre électronique réalisée selon les enseignements de l'invention. Elle comporte une carrure 1 dans laquelle se situe un affichage analogique classique composé d'un cadran horaire 2, d'une première aiguille 3 et d'une deuxième aiguille 4 montées pivotantes et coaxiales au centre du cadran 2. Sur le tour d'heure, à la périphérie du cadran, on distingue douze repères 5 régulièrement espacés de trente degrés qui sont destinés à repérer la position angulaire des aiguilles 3, 4 sur le cadran horaire 2 afin de faciliter la lecture des indications horaires. Un organe de commande 6 dont le rôle sera décrit plus loin, est visible en position trois heures.The figure 1 represents an electronic watch made according to the teachings of the invention. It comprises a caseband 1 in which there is a conventional analog display composed of a time dial 2, a first hand 3 and a second hand 4 mounted pivoting and coaxial in the center of the dial 2. On the hour turn , on the periphery of the dial, there are twelve markers 5 regularly spaced thirty degrees which are intended to locate the angular position of the needles 3, 4 on the time dial 2 to facilitate the reading of time indications. A control member 6 whose role will be described later, is visible in the three o'clock position.

La montre comporte également un mécanisme d'entrainement, un circuit électronique garde-temps fournissant un signal base de temps à partir d'une base de temps relié à un circuit de division, le circuit électronique garde-temps étant alimenté par une source d'énergie électrique non représentés. La montre comprend un premier moteur activé à partir du signal base de temps divisé pour cadencer l'heure, via un premier circuit de commande, qui entraine un affichage analogique de l'heure 3 ainsi qu'un second moteur activé à partir du signal base de temps divisé pour cadencé la minute, via un deuxième circuit de commande, qui entraine un affichage analogique de la minute 4. Les deux aiguilles ne sont donc pas reliées cinématiquement par le mécanisme d'entrainement mais sont entrainés par deux moteurs pas-à-pas indépendants commandés par le circuit électronique. Le circuit garde-temps comprend en outre des moyens pour dériver du signal base de temps, à la fin de chaque jour, un signal journalier et un circuit calendrier comprenant au moins un compteur de jours activés par le signal journalier, le compteur comprenant un sous compteur des dizaines du quantième et un sous compteur des unités du quantième. Les premier et deuxième circuits de commande respectivement des premier et deuxième moteurs reçoivent en outre respectivement un signal provenant du sous compteur des dizaines et un signal du sous compteur des unités, les signaux des deux sous compteurs étant représentatifs de leur état d'incrémentation.The watch also comprises a drive mechanism, an electronic time-keeping circuit providing a time-base signal from a time base connected to a division circuit, the electronic time-keeping circuit being powered by a source of time. electrical energy not shown. The watch includes a first motor activated from the divided time base signal for clocking the time, via a first control circuit, which causes an analog time display 3 and a second motor activated from the basic signal. of divided time for clocking the minute, via a second control circuit, which causes an analog display of the minute 4. The two needles are not kinematically connected by the drive mechanism but are driven by two step-by-step motors. not independent controlled by the electronic circuit. The time-keeping circuit further comprises means for deriving from the time base signal, at the end of each day, a daily signal and a calendar circuit comprising at least one counter of days activated by the daily signal, the counter comprising a sub-time. counter of the tens of the date and a sub-counter of the date units. The first and second control circuits respectively of the first and second motors respectively receive respectively a signal from the sub-counter of the tens and a sub-counter signal of the units, the signals of the two sub-meters being representative of their incremental state.

Dans un premier mode d'affichage, une aiguille 3, 4 indique l'heure et l'autre les minutes du temps courant, en référence à leurs positions angulaires respectives sur le cadran horaire 2. La mise à l'heure s'effectue par exemple par la rotation de l'organe de commande 6 préalablement positionné axialement dans une position de réglage. Dans ce mode d'affichage ainsi que lors de la mise à l'heure, la position de l'une des aiguilles 3, 4 est asservie électroniquement à la position de l'autre aiguille 3, 4 de manière à ce que les positions angulaires des deux aiguilles 3, 4 restent cohérentes vis-à-vis de l'heure affichée. De préférence, l'aiguille menante est celle indiquant les minutes et l'aiguille asservie est celle des heures.In a first display mode, a hand 3, 4 indicates the hour and the other the minutes of the current time, with reference to their respective angular positions on the time dial 2. The time is set by example by the rotation of the control member 6 previously positioned axially in a setting position. In this display mode as well as when setting the time, the position of one of the needles 3, 4 is electronically controlled at the position of the other needle 3, 4 so that the angular positions of the two needles 3, 4 remain consistent vis-à-vis the time displayed. Preferably, the driving needle is that indicating the minutes and the slave hand is that of hours.

La montre possède un deuxième mode d'affichage activable sur demande par une pression sur l'organe de commande 6. Cette pression permet de générer un signal d'appel du quantième de sorte que dans ce deuxième mode d'affichage, la montre indique le quantième au lieu d'indiquer l'heure. Le premier circuit de commande permet dont de placer la première aiguille 3 dans la position correspondant au chiffre des dizaines du quantième représentatif de l'état du sous compteur des dizaines tandis que le deuxième circuit de commande permet de placer la deuxième aiguille 4 dans la position correspondant aux unités du quantième représentative de l'état du sous compteur des unités. Le réglage de la date s'effectue lorsque le deuxième mode d'affichage est activé soit par rotation de l'organe de commande 6 dans la position de réglage soit par pression sur un poussoir de réglage non représenté. Une nouvelle pression sur l'organe de commande 6 permet de revenir au premier mode d'affichage. Le retour au premier mode d'affichage peut également s'opérer automatiquement après une temporisation d'une durée prédéfinie.The watch has a second display mode that can be activated on demand by pressing on the control member 6. This pressure makes it possible to generate a call signal of the date so that in this second display mode, the watch indicates the date instead of indicating the time. The first control circuit makes it possible to place the first hand 3 in the position corresponding to the tens digit of the date representative of the state of the tens undercounter while the second control circuit makes it possible to place the second hand 4 in the position corresponding to the units of the date representative of the state of the sub-counter of the units. The date is set when the second display mode is activated either by rotating the control member 6 in the adjustment position or by pressing a not shown adjustment pushbutton. A new pressure on the control member 6 returns to the first display mode. The return to the first display mode can also be performed automatically after a delay of a predefined duration.

Dans le mode de réalisation présenté à la figure 1, les chiffres zéro à trois des dizaines sont donnés par la première aiguille 3 respectivement dans les positions de midi à trois heure du cadran horaire 2. Les chiffres zéro à neuf des unités sont donnés par la deuxième aiguille 4 respectivement dans les positions de midi à neuf heure. Ainsi, les positions des première 3 et deuxième 4 aiguilles indiquant respectivement les dizaines et les unités du quantième sont ordonnées dans le sens horaire. Il semble plus naturel que la petite aiguille des heures soit la première aiguille 3 indiquant les dizaines et que la grande aiguille des minutes soit la deuxième aiguille 4 des unités mais cela pourrait également être l'inverse. Dans la configuration représentée à la figure 1, la première aiguille 3 est en position une heure et la deuxième aiguille 4 est en position trois heure. Le quantième affiché est donc le treize. Des moyens de mémorisation permettent de conserver en mémoire et de faire évoluer l'ensemble des informations horaires indépendamment du mode d'affichage actif.In the embodiment presented at figure 1 , the digits zero to three of the tens are given by the first hand 3 respectively in the positions of noon to three o'clock of the time dial 2. The numbers zero to nine of the units are given by the second hand 4 respectively in the positions of noon to nine hours. Thus, the positions of the first 3 and second 4 hands respectively indicating the tens and the units of the date are ordered in the clockwise direction. It seems more natural that the small hour hand is the first hand 3 indicating the tens and that the large minute hand is the second hand 4 units but it could also be the opposite. In the configuration shown in figure 1 , the first needle 3 is in one hour position and the second hand 4 is in the three o'clock position. The displayed date is thirteen. Storage means make it possible to keep in memory and to modify all the time information independently of the active display mode.

L'invention porte également sur une montre squelette dépourvue de cadran. D'une façon générale, le cadran horaire 2 s'entend comme un objet géométrique permettant de repérer la position angulaire des aiguilles en référence à la position zénithale. Il n'est pas lié à une pièce particulière de la montre, le repérage angulaire pouvant par exemple être donné par la carrure, la platine ou la glace. L'organe de commande 6 est ici la couronne de mise à l'heure mais pourrait tout aussi bien être un moyen différent comme un bouton poussoir.The invention also relates to a skeleton watch devoid of a dial. In general, the hour dial 2 is understood as a geometric object for identifying the angular position of the needles in reference to the zenith position. It is not linked to a particular part of the watch, the angular registration being able for example to be given by the caseband, the plate or the ice. The control member 6 is here the crown setting time but could just as easily be a different way as a push button.

Ainsi, la montre selon l'invention permet de se passer de moyens d'affichage spécifique du quantième tels un disque de quantième ou un ou plusieurs cadrans annexes.Thus, the watch according to the invention makes it possible to dispense with date-specific display means such as a date disc or one or more ancillary dials.

Elle offre également une meilleure lisibilité du quantième comparativement aux autres solutions connues d'affichage par des aiguilles ou à un affichage dans un guichet de petite dimension. En effet, la lecture des chiffres des dizaines et des unités en fonction de la position angulaire des aiguilles est intuitive car elle correspond à la lecture de l'heure sur un cadran. De plus, les aiguilles sont d'une taille bien supérieure à celles des caractères ou des graduations permettant de lire le quantième dans les montres de l'art antérieur. La prise d'information d'un seul coup d'oeil est ainsi facilitée et le risque d'erreur de lecture diminuée. Les personnes malvoyantes capables de lire l'heure mais pas les détails plus fins peuvent, pour la première fois, lire le quantième sur une montre à aiguilles. De façon similaire, les presbytes n'ont plus la nécessité de mettre leurs lunettes pour lire cette information. Contrairement aux solutions de l'art antérieur, il est également possible de lire le quantième dans l'obscurité pour peu que les aiguilles et les repères du cadran soient luminescents.It also offers better readability of the date compared to other known solutions of display by needles or a display in a small window. Indeed, the reading of the tens and units figures according to the angular position of the hands is intuitive because it corresponds to the reading of the time on a dial. In addition, the needles are much larger in size than the characters or graduations for reading the date in the watches of the prior art. The taking of information at a glance is thus facilitated and the risk of reading error decreased. Visually impaired people who can read the time but not the finer details can, for the first time, read the date on a clock. Similarly, presbyopes no longer need to wear their glasses to read this information. Unlike the solutions of the prior art, it is also possible to read the date in the dark if the hands and dial markers are luminescent.

Enfin, la solution apportée par l'invention permet de soigner l'esthétique de la montre sans altérer ses fonctionnalités. La fonction quantième peut ainsi être totalement discrète et indécelable.Finally, the solution provided by the invention makes it possible to heal the aesthetics of the watch without altering its functionalities. The date function can thus be totally discrete and undetectable.

La figure 2 représente une variante de l'affichage du quantième d'une montre selon l'invention. D'une façon originale, les positions des première 3 et deuxième 4 aiguilles indiquant les dizaines et les unités du quantième sont ordonnées selon des sens opposés, dans le sens horaire pour les unités et dans le sens antihoraire pour les dizaines. Les chiffres zéro, un, deux et trois des dizaines du quantième correspondent aux positions respectives midi, onze, dix et neuf heure du cadran horaire 2. De la même façon que pour le premier mode de réalisation, les positions de la deuxième aiguille 4 indiquant les unités du quantième de zéro à neuf correspondent aux positions respectives de midi à neuf heures du cadran horaire. Dès lors que le chiffre indiqué ne correspond pas au chiffre de l'heure pointé sur le cadran horaire, il peut être intéressant de prévoir un marquage 7 pour faciliter la lecture du quantième en rappelant la valeur correspondant à la position d'une aiguille 3, 4. Le quantième affiché sur la figure 2 est le treize.The figure 2 represents a variant of the display of the calendar of a watch according to the invention. In an original way, the positions of the first 3 and second 4 hands indicating the tens and the units of the date are ordered in opposite directions, in the clockwise direction for the units and in the counterclockwise direction for the tens. The zero, one, two and three digits of the calendar day correspond to the respective positions at noon, eleven, ten and nine o'clock of the time dial 2. In the same way as for the first embodiment, the positions of the second hand 4 indicate the date units from zero to nine correspond to the respective positions from noon to nine o'clock in the hourly dial. As soon as the number indicated does not correspond to the number of the hour pointed on the hour dial, it may be advantageous to provide a marking 7 to facilitate the reading of the date by recalling the value corresponding to the position of a needle 3, 4. The date displayed on the figure 2 is the thirteen.

Cette configuration permet de limiter les risques d'erreurs de lecture du quantième qui existaient dans le premier mode de réalisation. Dans le premier mode présenté, les première 3 et deuxième 4 aiguilles partagent les positions zéro, un, deux et trois. Deux jours par mois, les deux aiguilles sont superposées ce qui peut être une source de confusion en particulier quand la vue est altérée ou la visibilité faible. Par ailleurs, il est possible d'intervertir l'aiguille indiquant les unités avec celle indiquant les dizaines. Ce risque peut paraître faible étant donné que les dates correspondantes sont séparées au moins de trois jours. En revanche le risque de confusion sera maximal si l'interversion a lieu à l'occasion du réglage de la date. La configuration proposée dans le deuxième mode de réalisation permet d'éviter cet écueil en dissociant les zones d'affichage des dizaines et des unités. Les positions midi et neuf heures restent communes mais il ne peut pas y avoir de superposition et le risque d'interversion est limité puisqu'il ne faudrait plus seulement intervertir les deux aiguilles dans une même zone d'affichage mais intervertir les zones d'affichage elles-mêmes en plus des aiguilles.This configuration makes it possible to limit the risks of date reading errors that existed in the first embodiment. In the first mode presented, the first 3 and second 4 needles share the positions zero, one, two and three. Two days a month, the two needles are superimposed which can be a source of confusion especially when the view is impaired or visibility is low. In addition, it is possible to switch the needle indicating the units with the one indicating the tens. This risk may seem low since the corresponding dates are separated by at least three days. On the other hand, the risk of confusion will be maximum if the reversal takes place during the adjustment of the date. The configuration proposed in the second embodiment avoids this pitfall by dissociating the display areas tens and units. The 12 o'clock and 9 o'clock positions remain common but there can be no overlap and the risk of reversal is limited since it The two needles should be swapped in the same display area, but the display zones themselves should be swapped in addition to the needles.

La figure 3 représente un troisième mode de réalisation de l'affichage du quantième, ici encore dans la position indiquant le nombre treize. De façon originale, le chiffre zéro des dizaines et des unités correspond à la position commune six heure du cadran horaire. Contrairement aux deux modes précédents, les unités du quantième sont ordonnées de façon croissante dans le sens anti-horaire. Les positions successives correspondant aux unités sont espacées de trois minutes. Les chiffres des dizaines sont ordonnés dans le sens horaire et leur position correspond aux repères horaires six, sept, huit et neuf heures. Un marquage 7 des chiffres correspondant aux unités et aux dizaines du quantième a été porté sur le tour d'heure pour plus de clarté. L'espace angulaire entre les indications des dizaines est ainsi différent de celui entre les indications des unités mais pourrait tout aussi bien être identique. Chacun des repères des unités de zéro à neuf se situent sur la partie droite du cadran horaire de zéro à six heures. Inversement les indications des dizaines se trouvent sur la partie gauche du cadran de six heure à douze heure.The figure 3 represents a third embodiment of the display of the date, here again in the position indicating the number thirteen. In an original way, the zero digit of the tens and units corresponds to the six hour common position of the hour dial. Unlike the two previous modes, the date units are increasingly ordered in the counter-clockwise direction. The successive positions corresponding to the units are spaced three minutes apart. The numbers of the tens are ordered clockwise and their position corresponds to the six, seven, eight and nine o'clock hour markers. A marking 7 of the numbers corresponding to the units and tens of the date has been worn on the hour for clarity. The angular space between the indications of the tens is thus different from that between the indications of the units but could equally well be identical. Each of the unit marks from zero to nine are on the right side of the zero to six hour clock. Conversely the indications of the tens are on the left side of the dial from six to twelve o'clock.

Dans cette configuration, comme pour l'affichage des dizaines du deuxième mode de réalisation, les valeurs d'unité ou de dizaine indiquées par les aiguilles dans une position donnée ne correspondent plus à celles des heures du cadran horaire dans la position analogue. L'avantage de séparer le cadran en deux parties selon une direction verticale est de reproduire la disposition naturelle d'un nombre à deux chiffres dans lequel le chiffre des dizaines se trouve à la gauche du chiffre des unités. Cela respecte également le sens de lecture le plus courant de gauche vers la droite. Ainsi la lecture du quantième est plus intuitive si l'aiguille des dizaines est dans la partie gauche du cadran et l'aiguille des unités dans la partie droite. La valeur zéro en position six heure est également naturelle puisque à la position la plus basse correspond la valeur la plus faible.In this configuration, as for the display of the tens of the second embodiment, the unit or ten values indicated by the hands in a given position no longer correspond to those of the hours of the hour dial in the analogous position. The advantage of separating the dial in two parts in a vertical direction is to reproduce the natural arrangement of a two-digit number in which the tens digit is to the left of the units digit. This also respects the most common reading direction from left to right. Thus the reading of the date is more intuitive if the hand of tens is in the left part of the dial and the needle of the units in the right part. The zero value in the six o'clock position is also natural since the lowest position corresponds to the lowest value.

L'homme du métier pourra apporter de nombreuses variantes aux modes de réalisation présentés en combinant leurs différentes caractéristiques sans sortir du cadre de l'invention définie par les revendications. En particulier les positions repérant le zéro des unités et des dizaines pourraient être distinctes. Dans une variante du deuxième mode de réalisation, les dizaines de zéro à trois occupent respectivement les positions de neuf à douze heure.Those skilled in the art will be able to make numerous variations to the embodiments presented by combining their different characteristics without departing from the scope of the invention defined by the claims. In particular the positions marking the zero of the units and tens could be distinct. In a variant of the second embodiment, the tens of zero to three respectively occupy the positions of nine to twelve hours.

De préférence et en lien avec l'un ou l'autre des modes de réalisation décrits ci-dessus, le circuit électronique horloger commandant les moteurs d'entrainement des aiguilles d'affichage est agencé pour gérer l'affichage du quantième selon un circuit calendrier de type calendrier perpétuel. Une unité de gestion d'un circuit calendrier perpétuel comprenant des compteurs de jours, de mois et d'années permettant de commander la rotation d'un disque des quantièmes est connu par exemple des documents CH 663 512 et US4 300 222 .Preferably and in connection with one or the other of the embodiments described above, the electronic watchmaking circuit controlling the display pointer driving motors is arranged to manage the display of the date according to a calendar circuit. perpetual calendar type. A management unit of a perpetual calendar circuit comprising counters of days, months and years making it possible to control the rotation of a disk of the dates is known for example from documents CH 663 512 and US4,300,222 .
