Abstract

Mechanically driven timepiece has a non-circular movement that is combined with a chronograph mechanism comprising levers (5, 6, 10, 21) and a column wheel (4). All the levers of the chronograph mechanism are directly engaged with the column wheel (4), while being subjected to the pressure of return elastic elements such that all the displacements of the levers result from the step by step movement of the column wheel actuated by a single control lever (1).

Description

La présente invention se rapporte à une pièce d'horlogerie à mouvement de forme non circulaire muni d'un mécanisme de chronographe comprenant des bascules et une roue à colonnes.The present invention relates to a timepiece with non-circular shape movement provided with a chronograph mechanism comprising rockers and a column wheel.

Les mouvements de montres-bracelets munis d'un mécanisme de chronographe sont généralement circulaires. La raison principale en est que le mécanisme de chronographe occupe une surface importante. Or dans le cas d'un mouvement de forme non circulaire, la réduction de surface est généralement comprise entre 10% et 15% par rapport à la surface du cercle dans lequel ce mouvement de forme est inscrit. Cette perte de surface pour loger le mécanisme de chronographe s'ajoute à la surface occupée par le mécanisme d'échappement, représentant environ 30% de la surface restante, qui doit être laissée libre pour ne pas gêner le réglage de la montre.The movements of wristwatches equipped with a chronograph mechanism are generally circular. The main reason is that the chronograph mechanism occupies a large area. However, in the case of a non-circular shape movement, the surface reduction is generally between 10% and 15% with respect to the surface of the circle in which this shape movement is inscribed. This loss of surface to accommodate the chronograph mechanism adds to the area occupied by the exhaust mechanism, representing about 30% of the remaining area, which must be left free to not interfere with the setting of the watch.

On a déjà proposé des mécanismes de chronographes dont toutes les fonctions sont commandées par un seul poussoir qui agit sur une roue à colonnes à laquelle toutes les bascules du mécanisme de chronographe sont mises en prise directe par des ressorts de rappel. Un tel type de mécanisme de chronographe, ramassé autour de la roue à colonnes, permet de concentrer ses différents composants sur une surface plus réduite, mais apparemment personne n'a réalisé jusqu'ici qu'un tel mécanisme pouvait ouvrir de nouvelles possibilités pour incorporer un mécanisme de chronographe à un mouvement de forme non circulaire.Chronograph mechanisms have already been proposed, all the functions of which are controlled by a single pusher which acts on a column wheel to which all the latches of the chronograph mechanism are directly engaged by return springs. Such a type of chronograph mechanism, collected around the column wheel, makes it possible to concentrate its various components on a smaller surface, but apparently nobody has realized so far that such a mechanism could open new possibilities to incorporate a chronograph mechanism with a non-circular movement.

Un tel exemple de mécanisme de chronographe est décrit dans le document CH32314 et comporte une roue centrale des secondes qui porte une goupille pour entraîner à chaque tour un marteau en prise avec une roue d'un compteur des minutes positionnée par un sautoir.Such an example of a chronograph mechanism is described in the document CH32314 and features a central seconds wheel that carries a pin to drive at every turn a hammer engaged with a wheel of a minute counter positioned by a jumper.

On ne voit pas comment le déplacement du marteau autour d'un axe selon un mouvement alternatif permet de faire tourner la roue du compteur des minutes. Donc la liaison entre le compteur des secondes et celui des minutes est inopérante.We do not see how moving the hammer around an axis in a reciprocating motion makes it possible to rotate the wheel of the minute counter. So the connection between the seconds counter and the minutes counter is inoperative.

A cet effet, la présente invention a pour objet une pièce d'horlogerie à mouvement de forme non circulaire associé à un mécanisme de chronographe tel que défini par la revendication 1.For this purpose, the subject of the present invention is a timepiece with non-circular shape movement associated with a chronograph mechanism as defined by claim 1.

L'avantage de la solution proposée est de permettre de réduire la place occupée par le mécanisme de chronographe et d'offrir ainsi la possibilité de réaliser en particulier une montre-bracelet de forme munie d'un tel mécanisme.The advantage of the proposed solution is to reduce the space occupied by the chronograph mechanism and thus offer the possibility of achieving in particular a wristwatch shaped with such a mechanism.

Avantageusement, le mouvement d'horlogerie de forme non circulaire auquel le mécanisme de chronographe est associé est un mouvement comportant un mobile démultiplicateur supplémentaire entre le barillet et la roue de centre aussi appelée grande moyenne, permettant de faire tourner le barillet plus lentement et d'y loger ainsi un ressort moteur susceptible de faire marcher le mouvement pendant environ 10 jours de manière à assurer une période de marche utile de 8 jours.Advantageously, the clockwork movement of non-circular shape to which the chronograph mechanism is associated is a movement comprising an additional reduction mobile between the barrel and the center wheel also called large average, to rotate the barrel more slowly and In this way, a motor spring can be housed, which can make the movement work for about 10 days in order to ensure a useful working period of 8 days.

De préférence, avec une réserve de marche portant sur une durée aussi longue, le mouvement est encore muni d'un mécanisme indicateur de réserve de marche.Preferably, with a power reserve for such a long duration, the movement is still provided with a power reserve indicator mechanism.

Avantageusement, le mécanisme de chronographe objet de l'invention est complètement intégré au mouvement de forme, c'est-à-dire que l'ensemble des organes qui le composent sont directement montés sur les différents ponts du rouage sans support intermédiaire permettant une utilisation optimale de l'espace aussi bien en surface qu'en hauteur.Advantageously, the chronograph mechanism that is the subject of the invention is completely integrated in the shape movement, that is to say that all the components of which it is composed are directly mounted on the various decks of the gear train. without intermediate support allowing an optimal use of the space as well in surface as in height.

Le mouvement de montre de forme non circulaire illustré par la figure 1 montre en particulier un mécanisme de chronographe, une bascule de commande 1 montée pivotante autour d'une vis à portée 1a vissée dans le pont de barillet B et dont une extrémité 1b est destinée à être reliée à un poussoir unique (non représenté) coaxial à la tige de remontoir T. En variante, comme illustré en traits pointillés sur la figure 3, l'extrémité 1b de la bascule 1 pourrait aussi se situer en face de « 2 heures ». L'autre extrémité de cette bascule de commande 1 se termine par un cliquet 2 en prise avec une denture à rochet 4a (figure 3) d'une roue à colonnes 4.The non-circular shape watch movement illustrated by the figure 1 shows in particular a chronograph mechanism, a control lever 1 pivotally mounted around a screw 1a screwed into the barrel bridge B and one end 1b is intended to be connected to a single pusher (not shown) coaxial with the winding stem T. Alternatively, as illustrated in dashed lines on the figure 3 , the end 1b of the flip-flop 1 could also be in front of "2 hours". The other end of this control lever 1 terminates in a pawl 2 engaged with ratchet teeth 4a ( figure 3 ) a column wheel 4.

Un ressort de rappel r1 tend à ramener la bascule de commande 1 dans une position de repos illustrée par la figure 1, contre une butée 1d travaillant avec 1e bord d'une ouverture ovale 1c, délimitant ainsi deux positions limites. Un autre ressort de rappel r2 tend à maintenir le cliquet 2 constamment en prise avec la denture à rochet 4a.A return spring r 1 tends to return the control lever 1 in a rest position illustrated in figure 1 against a stop 1d working with the edge of an oval opening 1c, thus defining two limit positions. Another return spring r 2 tends to keep the pawl 2 constantly in engagement with the ratchet toothing 4a.

Cette roue à colonnes 4 est sélectivement en prise directe avec l'ensemble des bascules du mécanisme de chronographe. L'une de ces bascules est la bascule 5 des marteaux de remise à zéro portant deux marteaux 5a, 5b et pivotée autour d'un axe 5c solidaire du pont de barillet B. Cette bascule 5 est en prise avec un ressort de rappel r5 qui la presse constamment en direction de la roue à colonnes 4.This column wheel 4 is selectively in direct contact with all the latches of the chronograph mechanism. One of these rockers is the rocker 5 of the reset hammers carrying two hammers 5a, 5b and pivoted about an axis 5c integral with the barrel bridge B. This rocker 5 is engaged with a return spring r 5 which constantly presses it towards the column wheel 4.

Une autre bascule constitue un frein 6 poussé constamment contre la roue à colonnes 4 par un bras élastique 6a venu d'étampage avec le frein 6 et prenant appui contre une butée 6c. Ce frein 6 est monté pivotant autour d'une vis à portée 6b vissée dans le pont de barillet B.Another rocker is a brake 6 constantly pushed against the column wheel 4 by an elastic arm 6a stamped with the brake 6 and bearing against a stop 6c. This brake 6 is pivotally mounted around a screw 6b screwed into the barrel bridge B.

Une troisième bascule est la bascule d'embrayage 10 qui présente une ouverture de pivotement mobile semi-circulaire 10a montée pivotante autour d'une surface circulaire 14a d'une plaquette de pivotement 14, elle-même montée pivotante autour d'une vis 14b vissée dans un pont S de la roue de secondes 15a (figure 11). La position angulaire de cette plaquette de pivotement 14 est réglable autour de l'axe de cette vis 14b à l'aide d'un excentrique 13.A third flip-flop is the clutch rocker 10 which has a semi-circular mobile pivoting opening 10a pivotally mounted around a circular surface 14a of a pivoting plate 14, itself pivotally mounted around a screw 14b screwed in a bridge S of the seconds wheel 15a ( figure 11 ). The angular position of this pivoting plate 14 is adjustable around the axis of this screw 14b by means of an eccentric 13.

Comme on peut le constater sur la coupe de la figure 11, l'ouverture de pivotement mobile semi-circulaire 10a présente une portée qui débouche sur la face supérieure de la bascule 10. Cette portée sert à retenir la bascule 10 entre le pont de secondes S et une portée entourant la surface circulaire 14b de la plaquette de pivotement 14, débouchant sur la face inférieure de cette plaquette de pi-, votement 14 et s'ajustant sur la portée complémentaire de l'ouverture de pivotement mobile semi-circulaire 10a de la bascule 10.As can be seen from the section of the figure 11 , the semicircular movable pivoting opening 10a has a range that opens on the upper face of the rocker 10. This range serves to retain the rocker 10 between the bridge of seconds S and a scope surrounding the circular surface 14b of the pivot plate 14, opening on the underside of this plate 14 and adjusting on the complementary bearing of the semicircular mobile pivoting opening 10a of the rocker 10.

La bascule d'embrayage 10 comporte deux parties supérieure 10s et inférieure 10i assemblées par une vis 10v (figure 11) entre lesquelles une roue d'embrayage 16 est montée pivotante. Cette roue d'embrayage 16 est constamment en prise avec une roue entraîneuse 15 solidaire de l'axe de la roue de secondes 15a.The clutch rocker 10 comprises two upper 10s and lower 10i parts assembled by a screw 10v ( figure 11 ) between which a clutch wheel 16 is pivotally mounted. This clutch wheel 16 is constantly engaged with a driving wheel 15 integral with the axis of the seconds wheel 15a.

Comme on le voit sur la figure 11, le pont de secondes S est plus haut que le pont du rouage de finissage R. La différence de hauteur est choisie de manière à permettre à la roue entraîneuse 15 et à la bascule d'embrayage 10 de passer au-dessus du pont du rouage de finissage R. Grâce à cette disposition et au système de pivotement de la bascule d'embrayage 10 selon un axe coaxial à celui de la roue de secondes 15a et de la roue entraîneuse 15, la surépaisseur due au mécanisme de chronographe est ramenée à un minimum. Seul l'axe de la roue de secondes 15a portant la roue entraîneuse nécessite une modification du mouvement d'horlogerie, tout le reste du mécanisme de chronographe se situant hors du mouvement d'horlogerie ne génère aucune modification de ce mouvement.As we see on the figure 11 , the seconds bridge S is higher than the deck of the finishing train R. The difference in height is chosen so as to allow the driving wheel 15 and the clutch rocker 10 to pass over the bridge of the cog With this arrangement and with the pivoting system of the clutch rocker 10 along an axis coaxial with that of the seconds wheel 15a and the driving wheel 15, the extra thickness due to the chronograph mechanism is reduced to one minimum. Only the axis of the seconds wheel 15a carrying the driving wheel requires a modification of the watch movement, all the rest of the chronograph mechanism being outside the clockwork movement generates no change in this movement.

Un ressort de rappel r10 (figure 1) pousse la bascule d'embrayage 10 dans le sens des aiguilles d'une montre autour de la surface circulaire de pivotement 14, de sorte que l'extrémité de cette bascule d'embrayage 10 est constamment en contact avec la roue à colonnes 4.A return spring r 10 ( figure 1 ) pushes the clutch rocker 10 clockwise around the circular pivoting surface 14, so that the end of this clutch rocker 10 is constantly in contact with the column wheel 4.

Une dernière bascule, dite bascule inter compteurs 21 est montée pivotante autour d'une vis à portée 21a. Un ressort de rappel r21 pousse cette bascule 21 dans le sens des aiguilles de la montre et presse une de ses extrémités contre la roue à colonnes 4 (figure 3). L'autre extrémité de cette bascule porte une roue intermédiaire 18 du compteur des minutes qui est constamment en prise avec une roue 8 du compteur des minutes dont l'axe de pivotement 8a (figure 10) traverse tout le mouvement pour sortir du côté cadran du mouvement pour porter une aiguille (non représentée) du compteur des minutes. Cette roue 8 du compteur des minutes porte encore une came en forme de coeur 9 (figure 3) destinée à coopérer avec le bras 5a du marteau 5 de remise à zéro lors de la remise à zéro du compteur des minutes.A last flip-flop, said inter-meter flip-flop 21 is pivotally mounted around a screw 21a. A return spring r 21 pushes this latch 21 clockwise and presses one of its ends against the column wheel 4 (FIG. figure 3 ). The other end of this rocker carries an intermediate wheel 18 of the minute counter which is constantly engaged with a wheel 8 of the minute counter whose pivot axis 8a ( figure 10 ) crosses the entire movement to exit the dial side of the movement to carry a needle (not shown) of the minute counter. This wheel 8 of the minute counter again carries a heart-shaped cam 9 ( figure 3 ) intended to cooperate with the arm 5a of the reset hammer 5 during the resetting of the minute counter.

Une roue de chronographe 19 est encore pivotée au centre du mouvement et son axe traverse tout le mouvement pour sortir du côté cadran du mouvement pour porter une aiguille (non représentée) du compteur des secondes. Cette roue de chronographe 19 porte un doigt d'entraînement 17 de la roue intermédiaire 18 du compteur des minutes (figures 5 et 9) entraînant la roue 8 de ce compteur à chaque rotation, c'est-à-dire une fois par minute. Cette roue de chronographe porte aussi une came de remise à zéro en forme de coeur 20 (figure 3) destinée à coopérer avec le bras 5b du marteau de remise à zéro 5.A chronograph wheel 19 is further pivoted at the center of the movement and its axis traverses the entire movement to exit the dial side of the movement to carry a needle (not shown) of the seconds counter. This chronograph wheel 19 carries a drive finger 17 of the intermediate wheel 18 of the minute counter ( figures 5 and 9 ) driving the wheel 8 of this counter every rotation, that is to say once a minute. This chronograph wheel also carries a heart-shaped reset cam 20 ( figure 3 ) intended to cooperate with the arm 5b of the reset hammer 5.

Un ressort sautoir 3 est en prise avec la denture à rochet 4a de la roue à colonnes et un ressort sautoir 7 est en prise avec la roue 8 du compteur des minutes.A jumper spring 3 is engaged with the ratchet toothing 4a of the column wheel and a jumper spring 7 is engaged with the wheel 8 of the minute counter.

La pénétration de la roue d'embrayage 16 portée par la bascule d'embrayage 10 est réglable au moyen d'une butée 11 constituée par un excentrique, servant à limiter le pivotement de la bascule d'embrayage 10 dans le sens des aiguilles d'une montre, permettant ainsi de régler la pénétration de la denture de la roue d'embrayage dans celle de la roue de chronographe 19.The penetration of the clutch wheel 16 carried by the clutch rocker 10 is adjustable by means of an abutment 11 constituted by an eccentric, serving to limit the pivoting of the clutch rocker 10 in the clockwise direction. a watch, thus making it possible to regulate the penetration of the gearing of the clutch wheel in that of the chronograph wheel 19.

Une autre butée excentrique 12 sert à limiter le pivotement de la bascule intermédiaire 21 dans le sens des aiguilles d'une montre et par conséquent la pénétration du doigt d'entraînement 17 dans la denture de la roue intermédiaire 18.Another eccentric stop 12 serves to limit the pivoting of the intermediate lever 21 in the direction of clockwise and consequently the penetration of the drive finger 17 into the toothing of the intermediate wheel 18.

La figure 2 montre le rouage du mouvement de la montre. Outre les roues habituelles que l'on retrouve dans tous les mouvements d'horlogerie mécaniques, à savoir, les roues de centre 23 de moyenne 25 de seconde 26 et d'échappement 27, ce mouvement comporte un mobile supplémentaire 24 entre la denture du barillet 22 renfermant le: ressort moteur (non représenté) et le pignon 23a de la roue de centre 23. Ce mobile supplémentaire 24 augmente la démultiplication entre le barillet 22 et la roue de centre 23, de sorte que le barillet 22 tourne plus lentement que dans un mouvement classique, ce qui permet d'augmenter la réserve de marche de la montre d'environ deux jours pour une montre classique à environ dix jours dans ce cas, soit 8 jours utiles.The figure 2 shows the workings of the watch movement. In addition to the usual wheels found in all mechanical watch movements, namely, center wheels 23 of average 25 of second 26 and exhaust 27, this movement comprises an additional mobile 24 between the toothing of the barrel 22 enclosing the: motor spring (not shown) and the gear 23a of the center wheel 23. This additional mobile 24 increases the reduction between the barrel 22 and the center wheel 23, so that the barrel 22 rotates more slowly than in a classic movement, which increases the power reserve of the watch from about two days for a classic watch to about ten days in this case, 8 days useful.

Etant donné l'importance de la réserve de marche, il est utile d'avoir un indicateur de réserve de marche pour que l'utilisateur sache quand il doit remonter sa montre. Le rouage de l'indicateur de réserve de marche se trouve essentiellement du côté cadran du mouvement (figures 13 et 14). De l'autre côté, ce rouage comporte un renvoi 37 en prise d'une part avec le rochet 36 du barillet 22 et d'autre part avec une roue de différentiel 38, dont l'arbre 38a traverse le mouvement et comporte un carré 38b en prise avec un renvoi 31 engrenant avec un satellite 32 monté pivotant sur une tige 30a d'une couronne 30 portant le différentiel. Cette couronne 30 est en prise avec un renvoi 29 qui engrène avec un pignon 28a d'une roue 28 coaxiale au barillet 22 et qui est en liaison cinématique avec le barillet 22 grâce à un double pignon 39 engrenant simultanément avec la denture du barillet 22 et celle de la roue 28.Given the importance of the power reserve, it is useful to have a power reserve indicator so that the user knows when to reassemble his watch. The gearing of the power reserve indicator is essentially on the dial side of the movement ( Figures 13 and 14 ). On the other side, this train comprises a reference 37 engaged on the one hand with the ratchet 36 of the barrel 22 and on the other hand with a differential wheel 38, whose shaft 38a traverses the movement and comprises a square 38b engaged with a reference 31 meshing with a satellite 32 pivotally mounted on a rod 30a of a ring 30 carrying the differential. This ring 30 is engaged with a return 29 which meshes with a pinion 28a of a wheel 28 coaxial with the barrel 22 and which is in kinematic connection with the barrel 22 thanks to a double pinion 39 meshing simultaneously with the toothing of the barrel 22 and that of the wheel 28.

Le pignon 32a du satellite 32 engrène avec une roue intermédiaire 33 qui engrène avec une roue d'entraînement 34 dont le pignon 34a engrène avec un secteur denté 35 portant l'indicateur de réserve de marche (non représenté) qui se déplace sur un angle de 90° par exemple, entre l'armage et le désarmage du ressort moteur contenu dans le barillet 22.The pinion 32a of the satellite 32 meshes with an intermediate wheel 33 which meshes with a drive wheel 34 whose pinion 34a meshes with a toothed sector 35 carrying the power reserve indicator (not shown) which moves at an angle of 90 ° for example, between the arming and disarming of the mainspring contained in the barrel 22.

La figure 13 indique par des flèches les sens de rotations respectifs des différents mobiles du rouage indicateur de réserve de marche durant la phase d'armage du ressort de barillet. Les mobiles sans flèches correspondent à ceux qui sont fixes, c'est-à-dire le barillet 22, le double pignon 39, la roue 28 coaxiale au barillet 22, le renvoi 29 et la couronne de différentiel 30.The figure 13 indicates with arrows the respective directions of rotation of the various mobiles of the power reserve indicator gear during the winding phase of the mainspring. The mobiles without arrows correspond to those which are fixed, that is to say the barrel 22, the double pinion 39, the coaxial wheel 28 to the barrel 22, the return 29 and the differential ring 30.

La figure 14 indique par des flèches les sens de rotations respectifs des mobiles du rouage indicateur de réserve de marche durant la phase de désarmage du ressort de barillet. Les mobiles qui restent immobiles durant cette phase n'ont pas de flèches, il s'agit du rochet 36, du renvoi 37, de la roue de différentiel 38 et du renvoi entraîneur de satellite 31 solidaire de la roue de différentiel 38.The figure 14 indicates with arrows the respective directions of rotation of the mobile power indicator wheel reserve during the disarming phase of the mainspring. The mobiles that remain motionless during this phase do not have arrows, it is the ratchet 36, the reference 37, the differential wheel 38 and the satellite driver gear 31 integral with the differential wheel 38.

Les figures 3 à 8 montrent le seul mécanisme de chronographe au cours des différentes phases d'un cycle complet de fonctionnement. La figure 3 montre ce mécanisme remis à zéro. Les flèches indiquent quels sont les organes en mouvement et les sens respectifs des déplacements. Tous les organes du mécanisme sont au repos à l'exception de la roue d'entraînement 15 et de la roue d'embrayage 16 qui sont en liaison cinématique avec le rouage 22-27 du mouvement de la montre.The Figures 3 to 8 show the only chronograph mechanism during the different phases of a complete cycle of operation. The figure 3 shows this mechanism reset. The arrows indicate which organs are moving and the respective directions of movement. All the mechanism members are idle with the exception of the drive wheel 15 and the clutch wheel 16 which are kinematically connected to the wheel 22-27 of the movement of the watch.

La figure 4 illustre la phase de mise en marche du mécanisme de chronographe. Les flèches montrent quels sont les organes en mouvement et leurs sens de déplacements respectifs. Cette mise en marche est commandée par la bascule 1 consécutivement à une pression exercée sur son extrémité adjacente à la tige de remontoir T (figure 1). Cette pression fait tourner de 20° la roue à colonnes 4 dans le sens des aiguilles d'une montre et cette rotation provoque le déplacement de la bascule 5 dans le sens des flèches et la libération des marteaux 5a, 5b, ainsi que le déplacement des bascules d'embrayage 10 et inter compteur 21 dans les sens respectifs des flèches.The figure 4 illustrates the start-up phase of the chronograph mechanism. The arrows show which organs are moving and their respective directions of movement. This start-up is controlled by the rocker 1 following a pressure exerted on its end adjacent to the winding rod T ( figure 1 ). This pressure rotates the column wheel 4 by 20 ° in a clockwise direction and this rotation causes the rocker 5 to move in the direction of the arrows and the hammers 5a, 5b to be released, as well as the movement of the hammers. clutch rockers 10 and inter counter 21 in the respective directions of the arrows.

La figure 5 montre le chronographe en marche. Les leviers en prise avec les colonnes de la roue à colonnes 4 sont dans les mêmes positions que précédemment, et toutes les roues du mécanisme chronographe sont en mouvement dans les sens respectifs indiqués par les flèches. La bascule de commande 1 est ramenée dans la position de repos. En ce qui concerne la roue intermédiaire 18 et la roue du compteur de minutes 8 elles sont entraînées pas à pas par le doigt 17 de la roue de chronographe 19, une fois par révolution de cette roue 19, c'est-à-dire une fois par minute.The figure 5 shows the chronograph running. The levers engaged with the columns of the column wheel 4 are in the same positions as before, and all the wheels of the chronograph mechanism are moving in the respective directions indicated by the arrows. The control rocker 1 is returned to the rest position. Regarding the intermediate wheel 18 and the minute counter wheel 8 they are driven step by step by the finger 17 of the chronograph wheel 19, once per revolution of this wheel 19, that is to say one times per minute.

Le passage de la phase de la figure 5 à celle de la figure 6 correspond au passage de la mise en arrêt du rouage de chronographe consécutivement à un nouvel actionnement de la bascule de commande 1. Au cours de cette phase, le frein 6 se déplace dans le sens de la flèche et vient en appui contre la roue de chronographe 19 qu'il immobilise. Simultanément, la bascule d'embrayage 10 se déplace dans le sens de la flèche séparant la roue d'embrayage 16 de la roue de compteur 19.The transition from the phase of figure 5 to that of the figure 6 corresponds to the passage of the stopping of the chronograph wheel consecutively to a new operation of the control lever 1. During this phase, the brake 6 moves in the direction of the arrow and bears against the chronograph wheel 19 that he immobilizes. Simultaneously, the clutch rocker 10 moves in the direction of the arrow separating the clutch wheel 16 from the counter wheel 19.

La figure 7 montre le chronographe arrêté, c'est-à-dire que par rapport à la figure 6, on a cessé d'exercer une pression sur la bascule de commande 1, de sorte qu'elle est revenue en position de repos sous la pression du ressort de rappel r1, mettant ainsi le cliquet 2 en position prête pour actionner la roue à colonnes d'un nouveau pas de 20°. Dans cette position, le frein 6 retient la roue de chronographe 19 dans la position dans laquelle le mécanisme de chronographe a été arrêté, permettant la lecture du temps mesuré par ce mécanisme entre sa mise en marche et son arrêt.The figure 7 shows the chronograph stopped, that is to say that compared to the figure 6 , we stopped exercising press on the control lever 1, so that it has returned to the rest position under the pressure of the return spring r 1 , thus setting the pawl 2 in the ready position to actuate the column wheel by a new step of 20 °. In this position, the brake 6 holds the chronograph wheel 19 in the position in which the chronograph mechanism has been stopped, allowing the reading of the time measured by this mechanism between its start and stop.

La dernière fonction consiste à remettre à zéro les aiguilles du compteur de secondes et de celui des minutes. Elle est illustrée par la figure 8 dans laquelle on voit que le marteau 5 est poussé contre les cames en coeurs 9 et 20. Simultanément, le frein 6 libère la roue de chronographe 19, la bascule 21 libère le doigt 17, permettant ainsi la remise à zéro des aiguilles des compteurs de minutes et de secondes.The last function is to reset the hands of the seconds and minutes counter. It is illustrated by the figure 8 in which we see that the hammer 5 is pushed against the cams in hearts 9 and 20. Simultaneously, the brake 6 releases the chronograph wheel 19, the latch 21 releases the finger 17, thus allowing the reset of the hands of the counters of minutes and seconds.

La figure 3 montre les positions respectives des organes du mécanisme de chronographe après la remise à zéro, une fois que la bascule de commande 1 a été ramenée en position de repos par le ressort de rappel r1.The figure 3 shows the respective positions of the chronograph mechanism of organs after reset, once the control lever 1 has been brought in the rest position by the return spring r 1.
