Description

La présente invention se rapporte à une pièce d'horlogerie à calendrier à affichage grand format et à saut instantané comprenant un rouage indicateur de l'heure, un mobile des quantièmes comportant une roue de 31 dents, une roue des unités de 30 dents plus un espace correspondant à une dent pour l'entraînement d'un pignon des unités de 10 dents et une roue de quatre dents pour l'entraînement d'un pignon des dizaines de 4 dents, une came annuelle solidaire d'une roue de 12 dents, et des moyens d'entraînement reliés audit rouage indicateur de l'heure pour entraîner ledit mobile de quantième d'un tour par mois et la came annuelle d'un tour par an.The present invention relates to a timepiece with a calendar display with large format and instant jump including a time indicator train, a date mobile having a 31-tooth wheel, a wheel units of 30 teeth plus one space corresponding to a tooth for driving a pinion of the units of 10 teeth and a wheel of four teeth for driving a pinion of tens of 4 teeth, an annual cam secured to a wheel of 12 teeth, and drive means connected to said time indicator train for driving said date mobile by one turn per month and the annual cam one turn per year.

Il existe de nombreuses montres comportant diverses indications dérivées de l'heure, telles que la date, (jour, quantième, mois) les phases de la lune, l'indication de plusieurs fuseaux horaires notamment. La multiplication de ces indications rend dans la plupart des cas leur lecture difficile. Cette difficulté de lecture peut venir aussi bien de la disposition que de la grandeur des indications. Dans bien des cas, le changement d'indication n'est pas instantané mais traînant, surtout lorsqu'il s'agit d'un calendrier annuel, voire perpétuel. Les quantièmes sont souvent affichés par une aiguille se déplaçant en face d'un cadran de quantièmes, plutôt qu'avec des chiffres apparaissant dans une fenêtre ménagée dans le cadran, ce qui rend la lecture moins facile. En outre, l'affichage des quantièmes par un disque portant les quantièmes de 1 à 31 limite la grandeur possible de ces chiffres, en sorte que l'on a déjà proposé d'afficher les dizaines et les unités par deux disques séparés pour augmenter leur taille, ce qui complique le mécanisme.There are many watches with various indications derived from the time, such as the date, (day, date, month) the phases of the moon, the indication of several time zones in particular. The multiplication of these indications makes in most cases their difficult reading. This difficulty of reading can come as much from the disposition as from the size of the indications. In many cases, the change of indication is not instantaneous but shuffling, especially in the case of an annual or even perpetual calendar. The dates are often displayed by a needle moving in front of a date dial, rather than numbers appearing in a window in the dial, which makes reading less easy. In addition, the display of the dates by a disc bearing the dates from 1 to 31 limits the possible size of these figures, so that it has already been proposed to display the tens and units by two separate disks to increase their number. size, which complicates the mechanism.

Il est évident que plus il y a d'indications et plus la pièce d'horlogerie est petite, en particulier si il s'agit d'une montre-bracelet et non d'une montre de poche, plus les problèmes sont difficiles à résoudre. Même si de nombreuses solutions existent, on constate cependant qu'aucune ne répond à l'ensemble des exigences de plus en plus grandes en matière d'horlogerie compliquée s'adressant avant tout à des collectionneurs exigeants qui demandent à ce que les limites du possible soient repoussées de plus en plus loin. Il faut non seulement pouvoir vaincre de nouveaux défis techniques, mais que les dimensions de tels mécanismes restent acceptables pour une montre qui doit être portée au bras, aussi bien en ce qui concerne la surface que l'épaisseur et ceci sans nuire à la fiabilité qui reste le critère essentiel.It is obvious that the more indications there are and the shorter the timepiece, especially if it is a wristwatch and not a pocket watch, the more difficult the problems are. . Even if many solutions exist, however, we see that none of them meets all of the increasingly demanding requirements for complicated watchmaking, aimed first and foremost at demanding collectors who demand that the limits of the possible are pushed back further and further. We must not only be able to overcome new technical challenges, but the dimensions of such mechanisms remain acceptable for a watch that must be worn on the arm, both with regard to the surface and the thickness, without compromising the reliability remains the essential criterion.

Le but de la présente invention est précisément de faire en sorte que le mécanisme de calendrier de la pièce d'horlogerie permette un affichage grand format dans un calendrier à saut instantané.The object of the present invention is precisely to ensure that the timing mechanism of the timepiece allows a large format display in an instant jump calendar.

A cet effet, la présente invention a pour objet une pièce d'horlogerie à calendrier à affichage grand format et à saut instantané, telle que définie part la revendication 1.To this end, the subject of the present invention is a timepiece with a large-format display and instant jump, as defined by claim 1.

Avantageusement le calendrier de cette pièce d'horlogerie est un calendrier perpétuel et comporte l'affichage des jours et des mois.Advantageously, the calendar of this timepiece is a perpetual calendar and includes the display of days and months.

De préférence, ce calendrier comporte encore l'indication des phases de la lune qui est coaxiale à un rouage supplémentaire pour l'indication d'un second fuseau horaire, entraîné par le rouage indicateur principal situé au centre de la montre.Preferably, this calendar also includes an indication of the phases of the moon which is coaxial with an additional wheel for the indication of a second time zone, driven by the main indicator gear located in the center of the watch.

La conception de cette pièce d'horlogerie à calendrier est destinée à offrir un affichage clair, facile à lire, aussi bien en ce qui concerne la disposition des éléments affichés qu'en ce qui concerne la lisibilité, grâce à des caractères suffisamment grands. Toutes les indications affichées changent de manière instantanée et ne nécessitent de préférence aucune correction, celles-ci étant induites par la came annuelle.The design of this timepiece calendar is intended to provide a clear display, easy to read, both as regards the layout of the elements displayed only with respect to readability, thanks to sufficiently large characters. All displayed indications change instantaneously and preferably do not require any correction, these being induced by the annual cam.

D'autres particularités et avantages de la présente invention apparaîtront au cours de la description qui va suivre et qui se réfèrera aux dessins annexés qui illustrent, schématiquement et à titre d'exemple, une forme d'exécution de la pièce d'horlogerie à calendrier, objet de la présente invention.

  • La figure 1 est une vue en plan de cette forme d'exécution, dans laquelle on admet que les différents disques indicateurs sont transparents pour permettre de voir le mécanisme;
  • la figure 2 est une vue en plan du mécanisme de la figure 1 sans les disques indicateurs, montrant la position des différents organes le 28 février d'une année non bissextile aux environs de midi;
  • la figure 3 est une vue semblable à la figure 2, montrant la position des différents organes juste avant minuit, donc juste avant le changement de date;
  • la figure 4 est une vue semblable à la figure précédente, montrant la position des différents organes le 1er mars après le changement de date;
  • la figure 5 est une vue en coupe selon la ligne V-V de la figure 3.
Other features and advantages of the present invention will become apparent from the description which follows and which will refer to the accompanying drawings which illustrate, schematically and by way of example, an embodiment of the timepiece calendar object of the present invention.
  • The figure 1 is a plan view of this embodiment, in which it is assumed that the different indicator discs are transparent to allow to see the mechanism;
  • the figure 2 is a plan view of the mechanism of the figure 1 without the indicator discs, showing the position of the various organs on February 28 of a non-leap year at about noon;
  • the figure 3 is a view similar to the figure 2 , showing the position of the different organs just before midnight, so just before the change of date;
  • the figure 4 is a view similar to the previous figure, showing the position of the various bodies on March 1, after the date change;
  • the figure 5 is a sectional view along line VV of the figure 3 .

Les figures 1 et 2 montrent essentiellement le mécanisme de calendrier de la pièce d'horlogerie selon la présente invention qui comporte une roue d'entraînement 1 solidaire de la roue à canon ou roue des heures RC, illustrée sur la coupe de la figure 5, engrenant avec une roue 2 et qui fait un tour en douze heures. Le rapport entre ce pignon 2 et la roue d'entraînement 1 est de 2/1, en sorte que la roue 2 effectue un tour par jour.The figures 1 and 2 essentially show the calendar mechanism of the timepiece according to the present invention which comprises a drive wheel 1 integral with the cannon wheel or clock wheel RC, illustrated on the section of the figure 5 , meshing with a wheel 2 and making a turn in twelve hours. The ratio between this pinion 2 and the Drive wheel 1 is 2/1, so that wheel 2 performs one turn per day.

Cette roue 2 est solidaire d'une came 3 qui travaille avec une cheville 4a solidaire d'une bascule 4, montée pivotante autour d'un axe 4b. Cette bascule 4 se divise en deux bras qui se terminent chacun par un cliquet 5a, 5b pour l'entraînement pas à pas d'un mobile des quantièmes 7 de 31 dents, respectivement pour l'entraînement pas à pas d'une étoile 8 (figure 1) des jours de la semaine. Cette bascule 4 comporte une ouverture en arc de cercle 4c centrée sur son axe de pivotement 4b, dans laquelle une butée 4d est engagée. Cette bascule 4 est pressée contre une extrémité de cette ouverture 4c par un ressort de rappel 6 en prise avec une goupille 4e de la bascule 4.This wheel 2 is integral with a cam 3 which works with a pin 4a integral with a rocker 4, pivotally mounted about an axis 4b. This flip-flop 4 is divided into two arms, each of which terminates in a pawl 5a, 5b for the step-by-step training of a date wheel 7 of 31 teeth, respectively for stepwise driving of a star 8 ( figure 1 ) days of the week. This flip-flop 4 comprises an opening in a circular arc 4c centered on its pivot axis 4b, in which a stop 4d is engaged. This rocker 4 is pressed against one end of this opening 4c by a return spring 6 in engagement with a pin 4e of the rocker 4.

Une seconde bascule 9, qui constitue une bascule de correction, est montée pivotante autour du même axe 4b que la bascule 4. Elle est reliée à cette dernière par un bras élastique 9a qui prend appui contre la cheville 4a de la bascule 4, qui fait saillie sur les deux faces de cette bascule 4. La bascule 9 se termine par un cliquet 10 destiné à venir sélectivement en prise avec un décrochement 11a d'une came de correction 11, solidaire du mobile des quantièmes 7.A second flip-flop 9, which constitutes a correction flip-flop, is pivotally mounted about the same axis 4b as the flip-flop 4. It is connected to the latter by an elastic arm 9a which bears against the peg 4a of the flip-flop 4, which makes protruding on both sides of this rocker 4. The rocker 9 ends with a pawl 10 intended to selectively engage with a recess 11a of a correction cam 11, integral with the date mobile 7.

Le mobile des quantièmes 7 est encore solidaire de deux roues, une roue d'entraînement des unités 12, comprenant 30 dents et un espace vide correspondant à la 31ème dent en prise avec une étoile 13 d'affichage des unités des quantièmes, comportant 10 dents. La seconde roue solidaire du mobile des quantièmes 7 est une roue d'entraînement des dizaines 14, comprenant 4 dents en prise avec une étoile 15 d'affichage des dizaines des quantièmes. Chacune de ces étoiles 13, 15 est respectivement solidaire d'un disque annulaire 13a concentrique d'un disque 15a (figure 1 et 5), le disque annulaire 13a portant les chiffres des unités de 0 à 9 et le disque 15a portant les chiffres des dizaines de 0 à 3, le zéro pouvant être remplacé par un espace vide. Ces chiffres apparaissent au travers d'un guichet G ménagé à travers le cadran C de la pièce d'horlogerie (figure 5).The date mobile 7 is still secured to two wheels, a drive wheel of the units 12, comprising 30 teeth and a gap corresponding to the 31 st tooth in engagement with a star 13 for displaying the date units, comprising 10 teeth. The second integral wheel of the date mobile 7 is a tens 14 drive wheel, comprising 4 teeth engaged with a star 15 displaying tens of the dates. Each of these stars 13, 15 is respectively integral with a concentric annular disc 13a of a disc 15a ( figure 1 and 5 ), the annular disc 13a bearing the numbers of the units from 0 to 9 and the disk 15a bearing the tens numbers from 0 to 3, the zero can be replaced by a blank space. These figures appear through a window G formed through the dial C of the timepiece ( figure 5 ).

Le mobile des quantièmes 7 engrène dans un rapport 1/1 avec une roue 16 solidaire d'une came de saut instantané 17. Une bascule 18 pivotant autour d'un axe 18a est pressée contre la came de saut instantané 17 par un ressort 19. Cette bascule 18 porte un cliquet d'entraînement 20 qui est en prise avec un mobile annuel 21 de douze dents, solidaire d'une came annuelle 22 qui comporte des secteurs de rayons variables représentatifs du nombre de jours des mois de l'année. Une portion 22a de cette came annuelle 22 est solidaire d'un pignon satellite 23 (figure 1) engrenant avec une roue solaire des mois 24 solidaire du bâti du mécanisme de calendrier. Le rapport d'engrenage entre le pignon satellite 23 et la roue solaire des mois 24 est choisi pour que ce pignon satellite 23 fasse un tour pour quatre tours de la roue solaire des mois 24. La portion de came 22a comporte quatre côtés, dont trois sont à une même distance de l'axe du pignon 23, tandis que la quatrième est à une distance plus grande que les trois autres.The date mobile 7 meshes in a 1/1 ratio with a wheel 16 integral with an instantaneous jump cam 17. A rocker 18 pivoting about an axis 18a is pressed against the instantaneous jump cam 17 by a spring 19. This latch 18 carries a driving pawl 20 which is engaged with an annual mobile 21 of twelve teeth, integral with an annual cam 22 which has sectors of variable radii representative of the number of days of the months of the year. A portion 22a of this annual cam 22 is integral with a planet gear 23 ( figure 1 ) meshing with a sun wheel months 24 secured to the frame of the calendar mechanism. The gear ratio between the planet pinion 23 and the sun wheel 24 months is chosen for this pinion gear 23 to turn for four turns of the sun wheel months 24. The cam portion 22a has four sides, three of which are at the same distance from the axis of the pinion 23, while the fourth is at a greater distance than the other three.

La seconde bascule 9 comporte un bras palpeur 9b destiné à venir en contact avec le pourtour de la came annuelle à chaque déplacement des bascules 4 et 9, c'est-à-dire une fois par jour. Etant donné que les différentes portions de la came annuelle 22 ont des rayons différents en fonction de la longueur des mois, les amplitudes des déplacements de la bascule 9 et de son cliquet 10 varient et les différences entre les différentes amplitudes sont absorbées par le bras élastique 9a de la bascule 9.The second flip-flop 9 comprises a probe arm 9b intended to come into contact with the periphery of the annual cam at each movement of the flip-flops 4 and 9, that is to say once a day. Since the different portions of the annual cam 22 have different radii depending on the length of the months, the amplitudes of the movements of the rocker 9 and its pawl 10 vary and the differences between the different amplitudes are absorbed by the elastic arm 9a of the flip-flop 9.

Comme illustré par la figure 1, le mobile annuel 21 est solidaire d'un disque 21a portant les indications des douze mois de l'année.As illustrated by figure 1 , the annual mobile 21 is secured to a disc 21a bearing the indications of the twelve months of the year.

Le mobile des quantièmes 7 et le mobile annuel 21 ainsi que l'étoile des unités 13 et celle des dizaines 15 sont positionnés angulairement par des sautoirs respectifs, 25, 26, 27, 28.The mobile of the dates 7 and the annual mobile 21 as well as the star of the units 13 and that of the tens 15 are positioned angularly by respective jumpers, 25, 26, 27, 28.

Une des dents du mobile annuel 21 a une épaisseur sensiblement plus grande que les onze autres dents. Grâce à cette dent plus épaisse, le mobile annuel 21 entraîne une étoile à quatre branches 29 d'un pas par année. Cette étoile est solidaire d'un renvoi 30 qui entraîne un train de renvois 31, 32, 33, dont le dernier est solidaire d'une étoile à quatre branches 34 en prise avec un sautoir 35. Cette étoile 34 est également solidaire d'un disque 34a (figure 1) portant les chiffres 1, 2, 3 et la lettre B, pour l'indication d'un cycle de quatre années dont une année bissextile B.One of the teeth of the annual mobile 21 has a thickness substantially greater than the other eleven teeth. With this thicker tooth, the annual mobile 21 causes a four-branched star 29 of a step per year. This star is secured to a reference 30 which drives a gear train 31, 32, 33, the last of which is secured to a star with four branches 34 in engagement with a jumper 35. This star 34 is also integral with a disc 34a ( figure 1 ) bearing the numbers 1, 2, 3 and the letter B, for the indication of a cycle of four years including a leap year B.

L'étoile des jours de la semaine 8 (figure 1) est positionnée par un sautoir 41 et porte un disque 36 sur lequel sont affichés les jours de la semaine. Cette étoile 8 à sept branches est en prise avec une seconde étoile 37 également à sept branches positionnée par un sautoir 38. Cette seconde étoile 37 est solidaire d'un pignon 39 (figure 1) qui engrène avec un renvoi 40 qui engrène avec une roue 42 solidaire et coaxiale d'une roue 43 qui engrène avec une roue 44 pour l'indication des phases de la lune. Les rapports d'engrenages de ce train d'engrenage entre l'étoile des jours de la semaine 8 et la roue 44 pour l'indication des phases de la lune sont choisis pour que la roue 44 fasse un tour en trois mois lunaires, en sorte que cette roue 44 porte trois cercles 45 représentatifs de la lune, répartis à 120° l'un de l'autre sur la roue 44 en sorte que chacun d'eux sert à l'indication d'un cycle lunaire en combinaison avec un guichet (non représenté) de forme appropriée, ménagé à travers le cadran C, pour simuler les phases de croissance et de décroissance de la lune apparaissant dans le guichet.The star of the day of the week 8 ( figure 1 ) is positioned by a jumper 41 and carries a disc 36 on which are displayed the days of the week. This seven-pointed star 8 is engaged with a second star 37 also with seven branches positioned by a jumper 38. This second star 37 is integral with a pinion 39 ( figure 1 ) which meshes with a reference 40 which meshes with a wheel 42 integral and coaxial with a wheel 43 which meshes with a wheel 44 for the indication of the phases of the moon. The gear ratios of this gear train between the star of the weekdays 8 and the wheel 44 for the indication of the phases of the moon are chosen so that the wheel 44 makes a turn in three lunar months, in so that this wheel 44 carries three circles 45 representative of the moon, distributed at 120 ° to each other on the wheel 44 so that each of them serves to the indication of a lunar cycle in combination with an aperture (not shown) of suitable shape, formed through the dial C, to simulate the phases of growth and decay of the moon appearing in the window.

Une troisième roue 46 pivote sur le même axe que les roues 42, 43 du train d'engrenage des phases de la lune. Cette troisième roue 46 (figure 1) porte un disque 46a divisé en deux secteurs de 180° chacun, l'un étant noir et l'autre blanc pour indiquer les heures nocturnes et les heures diurnes à travers un guichet (non représenté) ménagé dans le cadran C de la pièce d'horlogerie. Comme on le voit sur la figure 1, la roue 46 engrène avec un renvoi 47 qui engrène avec une roue 48 coaxiale à la roue 44 des phases de la lune qui engrène avec la roue 2 du calendrier. Ces roues 46, 48 et 2 ont des rapports 1/1 entre elles, en sorte que la roue 46 fait un tour en 24 heures comme la roue 2. Ainsi, pendant 12 heures la couleur noire apparaît à travers le guichet du cadran et la couleur blanche apparaît à travers ce guichet durant les 12 heures suivantes.A third wheel 46 pivots on the same axis as the wheels 42, 43 of the moon phase gear train. This third wheel 46 ( figure 1 ) carries a disc 46a divided into two sectors of 180 ° each, one being black and the other white to indicate the nocturnal hours and the daytime hours through a window (not shown) formed in the dial C of the room d watchmaking. As we see on the figure 1 the wheel 46 meshes with a return 47 which meshes with a wheel 48 coaxial with the wheel 44 of the phases of the moon which meshes with the wheel 2 of the calendar. These wheels 46, 48 and 2 have ratios 1/1 between them, so that the wheel 46 makes a turn in 24 hours as the wheel 2. Thus, for 12 hours the black color appears through the window of the dial and the white color appears through this window during the next 12 hours.

Le fonctionnement du mécanisme calendrier décrit ci-dessus est le suivant :The operation of the calendar mechanism described above is as follows:

Toutes le 24 heures, la came 3 solidaire de la roue 2 du calendrier soulève progressivement les bascules 4 et 9 à l'encontre de la pression exercée par le ressort de rappel 6 sur la bascule 4. En pivotant, les cliquets 5a, 5b sont déplacés dans le sens des aiguilles de la montre autour de l'axe de pivotement 4b des bascules 4, 9, se dégageant ainsi des dentures 7 et 8 et le doigt 9b de la bascule 9 limite plus ou moins l'amplitude de pivotement de cette bascule 9 en fonction de la partie de la came annuelle 22 qui se trouve dans la trajectoire de ce doigt 9b et contre laquelle ce doigt 9b bute. Au cours du reste de son pivotement, la bascule 4 pivote par rapport à la bascule de correction 9, ce pivotement relatif de cette bascule 4 par rapport à la bascule 9 étant absorbé par la déformation du bras élastique 9a de cette bascule 9.Every 24 hours, the cam 3 integral with the wheel 2 of the calendar gradually lifts the latches 4 and 9 against the pressure exerted by the return spring 6 on the latch 4. By pivoting, the pawls 5a, 5b are moved clockwise about the pivot axis 4b of the latches 4, 9, thus disengaging the teeth 7 and 8 and the finger 9b of the latch 9 more or less limits the pivoting amplitude of this flip-flop 9 according to the portion of the annual cam 22 which is in the path of the finger 9b and against which the finger 9b abuts. During the rest of its pivoting, the rocker 4 pivots with respect to the correction rocker 9, this relative pivoting of this rocker 4 with respect to the rocker 9 being absorbed by the deformation of the elastic arm 9a of this rocker 9.

Durant la période allant du 1 au 29 du mois, la bascule 9 et son cliquet 10 n'ont aucune fonction, le cliquet 10 glissant contre la surface lisse de la came de correction 11 à chaque mouvement de va-et-vient des bascules 4 et 9. Dans le cas d'un mois de 30 jours, lors du changement de quantième entre le 30 et le 1 du mois suivant, lorsque le doigt 9b de la bascule 9 vient prendre appui contre une des portions de plus petit diamètre de la came annuelle 22, le cliquet 10 s'engage derrière le décrochement 11a de la came de correction 11, en sorte que lorsque la came 3 libère les bascules 4 et 9 à la force de rappel du ressort 6, le cliquet 10 entraîne la came de correction 11 de la valeur de deux pas de la roue de quantième 7, solidaire de cette came de correction 11, faisant passer le quantième du 30 au 01.During the period from 1 to 29 of the month, the flip-flop 9 and its pawl 10 have no function, the pawl 10 sliding against the smooth surface of the correction cam 11 with each reciprocating movement of the flip-flops 4 and 9. In the case of a month of 30 days, when the date change between the 30 and the 1 of the following month, when the finger 9b of the lever 9 comes to bear against one of the smaller diameter portions of the annual cam 22, the pawl 10 engages behind the recess 11a of the correction cam 11, so that when the cam 3 releases the latches 4 and 9 to the restoring force of the spring 6, the pawl 10 drives the cam correction 11 of the value of two steps of the date wheel 7, integral with this correction cam 11, passing the date of 30 to 01.

Lors du changement de quantième au cours d'un mois, soit il n'y a qu'un changement d'unité et la roue 12 entraîne d'un pas l'étoile 13, soit il y a changement simultané d'unité et de dizaine et les roues 12 et 14 entraînent simultanément d'un pas les étoiles 13, respectivement 15.During the change of date during a month, there is only one change of unit and the wheel 12 leads to one step 13, or there is simultaneous change of unit and ten and the wheels 12 and 14 simultaneously move the stars 13 and 15 respectively.

A la fin d'un mois de 31 jours, l'unité du quantième suivant 01 ne changeant pas, seule la dizaine change. C'est la raison pour laquelle la roue des quantièmes 12 comporte 30 dents et un espace correspondant à une dent manquante. Ainsi, lors du passage du 31 au 01, la dent manquante de la roue des quantièmes se trouve en face de l'étoile des unités 13, en sorte que celle-ci n'est pas entraînée et que le chiffre 1 est affiché deux jours consécutifs. Seule l'étoile des dizaines 15 est entraînée d'un pas par la roue des dizaines à quatre dents 14, faisant passer le disque des dizaines 15a du 3 au 0.At the end of a month of 31 days, the unit of the next 01 calendar does not change, only the ten changes. This is the reason why the date wheel 12 has 30 teeth and a space corresponding to a missing tooth. Thus, during the passage from 31 to 01, the missing tooth of the date wheel is in front of the star of the units 13, so that it is not driven and that the number 1 is displayed two days consecutive. Only the star of tens 15 is driven one step by the wheel of tens to four teeth 14, passing the tens disk 15a from 3 to 0.

Pour que le calendrier soit perpétuel, la came annuelle 22 comporte une portion 22a solidaire d'un pignon satellite 23 (figure 1), qui correspond à la correction à induire à la fin du mois de février qui compte soit 28 jours en année normale soit 29 jours en année bissextile. Cette portion de came 22a fait ¼ de tour chaque année et comporte quatre côtés, dont un est situé à une plus grande distance du centre du pignon satellite 23 que les trois autres. Lorsque le doigt 9b de la bascule de correction 9 se trouve en face de cette portion de came 22a au cours d'un mois de février de 28 jours, elle permet un basculement de la bascule de correction 9 de plus grande amplitude que dans le cas des autres mois, en sorte que le 28 février, le cliquet 10 de la bascule 9 vient derrière le décrochement de la came de correction 11, comme illustré par la figure 3, il s'agit là de l'amplitude maximum de la bascule de correction 9. Dès que la came de saut instantané 3 libère la bascule d'entraînement 4 à la pression du ressort 6, le cliquet 10 de la bascule de correction 9 entraîne la roue des quantièmes de 4 pas, faisant passer instantanément l'affichage des disques 13a, 15a du 28 au 01.For the calendar to be perpetual, the annual cam 22 comprises a portion 22a integral with a planet gear 23 ( figure 1 ), which corresponds to the correction to be made at the end of February, which is either 28 days in a normal year or 29 days in a leap year. This cam portion 22a is ¼ turn each year and has four sides, one of which is located at a greater distance from the center of the planet pinion 23 than the other three. When the finger 9b of the correction lever 9 is in front of this cam portion 22a during a February month of 28 days, it allows a tilting of the correction lever 9 of greater amplitude than in the case the other months, so that February 28, the pawl 10 of the rocker 9 comes behind the recess of the correction cam 11, as illustrated by the figure 3 this is the maximum amplitude of the correction lever 9. As soon as the instantaneous jump cam 3 releases the drive rocker 4 at the pressure of the spring 6, the catch 10 of the correction lever 9 causes the date wheel of 4 steps, instantly passing the display discs 13a, 15a from 28 to 01.

Lorsqu'il s'agit d'une année bissextile, c'est la surface de la portion 22a de la came 22 qui se trouve la plus éloignée du centre du pignon satellite 23 qui est en face du doigt 9b de la bascule de correction 9, la distance de cette surface au centre de pivotement de la came 22 étant située entre la distance des surfaces de la came 22 relatives aux mois de 30 jours et la distance des surfaces de la portion de came 22a correspondant aux mois de février de 28 jours, en sorte que le cliquet 10 viendra en prise avec le décrochement 11a de la came de correction 11 le 29 février et avancera la roue des quantièmes 7 simultanément et instantanément de trois pas. Ces corrections du mobile de quantième produisent le changement synchrone du mobile annuel 21 et du disque d'affichage des mois 21a solidaire de ce mobile annuel 21.In the case of a leap year, it is the surface of the portion 22a of the cam 22 which is furthest away from the center of the planet pinion 23 which faces the finger 9b of the correction lever 9 , the distance from this surface to the center of pivoting of the cam 22 being situated between the distance of the surfaces of the cam 22 relative to the months of 30 days and the distance of the surfaces of the cam portion 22a corresponding to the months of February of 28 days , so that the pawl 10 will engage with the recess 11a of the correction cam 11 February 29 and advance the date wheel 7 simultaneously and instantly three steps. These corrections of the date mobile produce the synchronous change of the annual mobile 21 and the 21a month display disk integral with this annual mobile 21.

Par contre, ces corrections n'ont aucune influence sur le cliquet 5b d'entraînement de l'étoile 8 solidaire du disque des jours de la semaine qui se succèdent évidemment de manière immuable, cette étoile 8 faisant avancer la roue 44 pour l'indication des phases de la lune chaque jour d'une fraction d'un cycle lunaire correspondant à un jour solaire.By cons, these corrections have no influence on the pawl 5b driving the star 8 secured to the disc of the days of the week which are obviously successive immovably, this star 8 advancing the wheel 44 for indication phases of the moon each day of a fraction of a lunar cycle corresponding to a solar day.

Le mouvement continu de la roue 2 en prise avec la roue d'entraînement 1 solidaire de la roue à canon RC est communiqué à la roue 46 portant les secteurs blanc/noir d'indication des heures diurnes et nocturnes avec un rapport 1/1.The continuous movement of the wheel 2 in engagement with the drive wheel 1 integral with the RC gun wheel is communicated to the wheel 46 carrying the white / black indicating sectors of the day and night hours with a 1/1 ratio.
