The invention also relates to a timepiece comprising at least one such movement, and / or at least one such rapid correction mechanism.

The invention relates to the field of watchmaking, and more particularly the field of timepieces with complications for displaying temporal quantities, such as calendar, moon phase, day, month, or the like.

More particularly, the invention relates to the field of chronographs equipped with such complications.

Background of the Invention

The display of temporal quantities such as the date, the moon phases, the tides, the day, the month, is generally performed on the mechanical timepieces with the help of mobile driven by the movement, most often by the hour wheel. Some of these temporal magnitudes require corrections by catch-up, either in the case of a calendar to catch leap years, or in the case of moon phases to compensate for the slight difference between the lunar months and the approximation made to it. by the wheel. These corrections may also be necessary in case of loss of references, for example following a shock on the timepiece.

Traditionally, such a display comprises a disc or an integral ring respectively of a toothed wheel or a ring gear, or the like, and the movement of the timepiece causes a certain pitch this wheel or crown, to the required frequency.

The correction of this display has long been carried out by an auxiliary push button, acting directly on the toothing, as in the patent US 508,467 in the name of Clark , Where such a pusher is constituted by a curved spring bearing against a tooth of the toothing which is retained by a jumper, each support on the curved spring advancing the pivoting of the toothing of a tooth.

The patent CH 671 317 in the name of Gagnebin described, in a similar manner, a push-button acting on a pivoting adjustment lever, acting on against a spring, and a tooth of the lever directly attacks the moon phase wheel, which cooperates with a jumper.

A similar arrangement is visible on the patent CH 4542 in the name of Abegglen , and a first pusher is pivotable and cooperates with a lunar wheel direct drive tooth. A second pivoting plunger rotates a star held by a jumper, which cooperates with a tooth, constituted by a spring, that includes a first date change wheel, to rotate it and cause a return which in turn causes a second date change wheel comprising a spring reminding a pivoting peripheral bracket ratchet function, causing in turn a date wheel.

These simple devices, however, have the disadvantage of the risk of a sealing defect in the pusher used for the correction of the display.

Also it was envisaged to control the display correction through a pre-existing adjustment means at the timepiece, in this case the winding rod and setting time in the case of a watch.

The patent CH 672 223 in the name of Catena describes a tide indicator, as well as moon phases, by action of the rod, in the setting position, in the negative direction. The mechanism has two gears, one upper driven on the hours barrel, the other lower, mounted frictionally on the latter, and each driving a ring, a superior superimposed on a lower one, and with gear ratios different within each gear-ring pair, so that the lower ring rotates more slowly than the upper, by decoupling a friction on the hour wheel. Days of the upper ring, and an adequate combination of gear ratios allow to visualize the phases of the moon according to a sector of the lower ring delimited by the upper ring. The upper wheel always follows the hour hand, the lower wheel is held by a ratchet when the hour wheel rotates in the negative direction, and it is then possible to correct the moon phase by rotating the upper ring alone.

The patent EP 0 107 177 in the name of Erard also discloses a mechanism for viewing moon phases, with synchronization by the crumb on time, and setting back to the timer. Similarly, the hour wheel carries a moon gear causing a return driving a moon wheel. This moon gear itself carries a moon phase gear mounted crazy and friction by means of an annular friction spring, the moon phase gear causing a return which causes a coaxial moon phase wheel to the moon wheel. The moon phase gear cooperates with a pawl that allows the moon phase gear to pivot only if the hour wheel is rotated clockwise, and otherwise locks it, allowing the moon phase correction.

The patent CH 577,197 , on behalf of EBAUCHES SA, describes a date correction mechanism, by a movable selector controlled by the control rod via the pull tab. This movable selector cooperates, in some of its positions, with a pivoting lever, one arm cooperates with the groove of the sliding pinion. This pivoting rocker carries, coaxially, a wheel arranged for, when the control rod is pushed, cooperate with the timer in a first stop position of the rocker, and a star arranged to mesh with a date ring in a second position of stop of the rocker. This pivoting rocker can still occupy, when the control rod is pulled, an intermediate position where the star is released from the ring, and where the wheel is released from the timer, but cooperates with the spout of this rotary selector, in a first selection position corresponding to a clockwise pivoting of the rod, and in a second selection position corresponding to the anti-clockwise pivoting of the rod. A preferential execution combining the functions of time setting, correction of the calendar, and reassembly, involves an intermediate rocker, pivotally mounted on the plate, which carries the crown wheel, and which cooperates, at the end of an arm that it comprises, with the zipper and / or the movable selector, which comprises a pin arranged for can be supported on the pivoting rocker carrying the wheel and the star. In a pushed position of the rod, and in the clockwise pivoting direction thereof, the crown wheel drives the additional rocker in cooperation with the movable selector in a position where it has no effect on the pivoting rocker which is in its intermediate position, and wherein the crown wheel can mesh with a barrel ratchet for reassembling it; in the anti-clockwise direction of the rod, the crown wheel is unsheathed from the barrel ratchet, and the selector is in a selection position. When the rod is pulled from the winding position, the intermediate rocker and the movable selector occupy a position where the pin of the latter pushes the pivoting lever to its first stop position, meshing the wheel of the pivoting lever with the timer to set the time; when the rod is pulled from the selection position, the intermediate rocker and the movable selector occupy a position which allows the pivoting rocker to pivot towards its second abutment position under the action of its return spring, allowing the meshing of the star with the date crown. This efficient device, however, requires a large number of flip-flops, and occupies space in an already very congested area.

The patent EP 0 230 878 on behalf of Complications SA presents a moon phase correction by the intermediate position of the rod, between the winding and setting positions. In this position, the sliding pinion meshes with a sliding device moving longitudinally in a light, between a position corresponding to a first direction of pivoting of the rod where it adjusts the date through a wheel bearing a star, and a another position corresponding to a second direction of opposite pivoting of the rod where it adjusts the moon phase, each time via a star. The training of the moon phase disc is carried out, from an additional hour wheel, by a wheel having two cooperating elastic fingers, one with a seven-tooth star of the days of the week held by a jumper, and the other with the toothing of the moon phase disc also held by a jumper; these elastic fingers make it possible to carry out the correction at any time without deterioration, even if the fingers are in contact with the star wheel.

The patent EP 0 479 147 in the name of ETA SA describes, analogously, a moon phase corrector by the control rod. It also comprises a movable sliding pinion in an arcuate light between drive positions of a date wheel or a moon phase wheel, with which it cooperates with an upper wheel, while a lower wheel of this player remains permanently meshed with a corrective wheel driven by the pivoting of the rod.

The patent document CH 651 172 in the name of Wiederrecht has a moon phase indicator mechanism with correction by the crown. A 59-tooth moonwheel, maintained by a jumper, cooperates with a pawl, which is pivotally and eccentrically mounted, movable between two abutting flats, on an intermediate wheel whose pivot is supported by a flat spring and which meshes with a pinion driven on the hour wheel. The ratchet, once a day, drives the moon disc, when an actuating tooth that includes this pawl enters the teeth of the moon disk, and when a rear edge of the pawl abuts against a first flat of the moon. intermediate wheel, thus allowing the driving of the moon wheel of a tooth plus a third of a tooth, so as to allow the jumper to jump a tooth. The setting of the lunar day time is carried out by alternating movements in front of and behind the winding crown of an amplitude corresponding to one or two hours around midday. When the crown drives the needles counter-clockwise, the intermediate wheel rotates clockwise, and when the pawl driving tooth contacts the leading edge of a tooth of the moon disk, the pawl tilts on its pivot until abutting by a front edge on another flat of the intermediate wheel. The driving tooth is then partially retracted, and, during the continuation of the pivoting of the intermediate wheel, the moon disk is driven in the opposite direction of a fifth tooth, before the pawl escapes the tooth of the disc of moon that he trained. The jumper then returns the moon disk to its previous position, so that the moon disk is driven stepwise in the clockwise direction to the desired position. This ingenious device requires components of very small size, difficult to mount, and it is quite fragile, especially in case of shocks.

Other types of mechanisms have been proposed for date or moon phase correction. So the patent document FR 2 862 143 on behalf of WATCHES BREGUET SA offers the combination of a moon phase indicator to a date disc, with a double-toothed ring. The date corrector is also used to correct moon phases. It comprises a pivoting rocker, having a light in which is movable a star which, in a clockwise rotation causes the lunar wheel toothing, and, in anti-clockwise pivoting, remains far away thanks to the light.

The patent document EP 1 730 605 in the name of BLANCPAIN presents a corrector device on horns, or under horns, in order to release the crown and the other possible pushers, including a pivoting lever provided with a seal.

The patent document EP 1 939 699 A1 on behalf of MONTRES BREGUET SA describes a multifunction coaxial corrector device for selecting or modifying display information by means of a single control member. A rotation of the control knob causes the movement of a rack and the positioning of the end of an arm of a rocker opposite a function corrector. Pressing a pushbutton makes it possible to activate and / or modify a selected function.

The patent document CH 688 171 in the name of Patek Philippe proposes, as an alternative to the control command by the rod or push button, a control by the pivoting of a mobile telescope, which carries two integral rotational crowns, one engaging a sky gear wheel through a friction clutch wheel, the other engaging a moon gear through a friction moon clutch wheel, both clutch wheels being frictionally mounted on a drive shaft provided with a friction gear, wheel meshing with a barrel. Wheel moon gear has an internal toothing cooperating with an eccentric moon phase wheel. A base plate has two lights, in which are moving the shafts of two clutch release gears of the sky, and moon. Depending on the pivoting direction of the mobile bezel, only one of these gears at a time can mesh with the corresponding friction clutch wheel. During the correction, the disengaging wheel concerned disengages by friction on the drive shaft outside the correction phase, the corresponding clutch return gear is not meshing with the corresponding intermediate gear. This construction offers an interesting alternative to known correction control means, but it requires a special construction of the timepiece concerned, particular care as to the seal, and represents a high manufacturing cost.

Apart from the correction mechanisms based on the use of the winding and setting rod, there are few solutions to make these corrections other than by additional pushers, which each time pose sealing problems , and represent a significant cost.

In particular, the equipment of timepieces such as chronographs must be rethought, so as not to increase the number of control members, to ensure tightness especially in deep diving conditions, and to maintain the cost of the correction function to a reasonable level.

Summary of the invention

The invention proposes to overcome the limitations of the prior art, by proposing a mechanism using a pre-existing control member on a timepiece, to make corrections of a magnitude related to time.

For this purpose, the invention relates to a mechanism for rapidly correcting a function display indicator for a movement or a workpiece watch, according to independent claim 1.

Detailed Description of the Preferred Embodiments:

The invention relates to the field of watchmaking, and more particularly the field of timepieces with complications for displaying temporal quantities, such as calendar, moon phase, day, month, or the like, or for the display of physical quantities such as atmospheric pressure or others.

More particularly, the invention is described in application to the field of chronographs equipped with such complications.

Thus, the invention relates to a fast correction mechanism 1 of a function display indicator 20 for a movement 100 or a timepiece 1000.

• des premiers moyens de commande 30 d'au moins une première fonction, liés à des premiers moyens d'affichage, et qui sont susceptibles d'occuper une position désarmée 31, ou au moins une position armée de commande 32 : Cette première fonction peut notamment consister dans la mise à l'heure de la pièce d'horlogerie, ou bien dans son remontage par la couronne. Dans l'exemple de réalisation illustré par les figures, les premiers moyens de commande 30 comportent une tige 33 de commande d'au moins la mise à l'heure, et la position désarmée 31 correspond à une position de butée T1 de la tige 33, laquelle est agencée pour occuper au moins une autre position armée T2 ou T3 de commande 32, de préférence par un mouvement longitudinal de la tige de commande, en général en traction par rapport à la position T1 correspondant à la position enfoncée de la tige 33, avec la couronne qui l'équipe au plus près du boîtier de la pièce d'horlogerie, tel que visible sur la figure 7.
• des seconds moyens de commande 40 d'une seconde fonction distincte de la première fonction, liés à des seconds moyens d'affichage, et qui sont susceptibles de passer, sous l'effet d'une action d'un utilisateur, d'une position de repos désarmée 41 vers une position armée de commande 42 de déclenchement instantané de la seconde fonction à l'issue duquel déclenchement instantané les seconds moyens de commande 40 sont rappelés par des moyens de rappel vers cette position de repos désarmée 41. Ces seconds moyens de commande 40 ne sont pas agencés pour rester dans la position armée de commande 42, qui n'est qu'une position d'actionnement transitoire. Dans une application préférée, mais nullement limitative, de l'invention, illustrée par les figures, le mouvement 100 d'horlogerie comporte un mouvement de chronographe, et cette seconde fonction peut consister en la commande de marche/arrêt du chronographe, ou bien en la remise à zéro du chronographe. Dans l'un ou l'autre cas, les seconds moyens de commande 40 comportent un bouton-poussoir 43 de commande du mécanisme de marche/arrêt ou du mécanisme de remise à zéro concerné. Ce bouton-poussoir 43 est généralement agencé pour entraîner, lors de son activation par action de poussée d'un utilisateur, une bascule directe 44, qui est rappelée vers la position de repos désarmée 41 du bouton-poussoir 43, par des moyens de rappel élastique. Dans le cas où le mouvement 100 ne comporte pas de telle bascule directe, le mécanisme de correction rapide 1 selon l'invention comporte une telle bascule directe 44 rappelée, par des moyens de rappel élastique qui lui sont associés, vers la position de repos désarmée 41 du bouton-poussoir 43 du chronographe.

This movement 100 or timepiece 1000 conventionally comprises, mounted directly or indirectly on a plate 10:

• first control means 30 of at least a first function, linked to first display means, and which are capable of occupying a disarmed position 31, or at least one commanded armed position 32: This first function can in particular consist in setting the time of the timepiece, or in its reassembly by the crown. In the exemplary embodiment illustrated by the figures, the first control means 30 comprise a rod 33 for controlling at least the time setting, and the disarmed position 31 corresponds to a stop position T1 of the rod 33, which is arranged to occupy at least one other armed position T2 or T3 control 32, preferably by a longitudinal movement of the control rod, generally in traction relative to the corresponding T1 position in the depressed position of the rod 33, with the crown which equips it as close as possible to the timepiece case, as visible on the figure 7 .
• second control means 40 of a second function distinct from the first function, linked to second display means, which are capable of passing, under the action of a user, a position disarmed rest 41 to a command armed position 42 instantaneous tripping of the second function at the end of which instantaneous tripping the second control means 40 are returned by return means to this disarmed rest position 41. These second means of control 40 are not arranged to remain in the armed control position 42, which is only a transient actuating position. In a preferred, but in no way limiting, application of the invention, illustrated by the figures, the watch movement 100 includes a chronograph movement, and this second function can consist of the on / off control of the chronograph, or else the reset of the chronograph. In either case, the second control means 40 comprise a push button 43 for controlling the on / off mechanism or the reset mechanism concerned. This push-button 43 is generally designed to cause, when it is activated by the push action of a user, a direct latch 44, which is biased towards the disarmed rest position 41 of the push-button 43, by means of recall. elastic. In the case where the movement 100 does not include such a direct flip-flop, the rapid correction mechanism 1 according to the invention comprises such a direct flip-flop 44 biased, by elastic return means associated with it, to the disarmed rest position. 41 of the pushbutton 43 of the chronograph.

This direct flip-flop 44 makes it possible not to dedicate the push-button 43 to a single function. Its shape is preferably in the form of a flag, with a wing folded square with respect to a rocking plane, this wing at right angle here comprises a first surface receiving the pulse of the push button 43, and an opposite surface, said control support 45, whose function is explained below. The square folding of this wing provides flexibility over the entire height of the pusher in the box.

The second control means 40 are distinct from the first control means 30.

This movement 100 or this timepiece 1000 further comprises, always mounted directly or indirectly on the plate 10, means for displaying a third function, which is different from these first and second functions. These means for displaying a third function are constituted by an indicator 20 which includes drive means 22 for driving it, for example a toothing or the like. The mechanism 1 according to the invention has the function of correcting or adjusting the position of this indicator 20. The preferred and usual case of a pivoting drive of the indicator 20 is described later in the description, but the The invention is also applicable for other types of movement of this indicator 20, for example a translation, or a complex trajectory along a cam track or the like.

This third function can take different kinds: preferably, and as described below, it can be the display of a moon phase, or a date. This third function can also relate to a display of tide time, day of the week, month, time zone, or the setting of an alarm clock, a ringtone, an account mechanism to countdown, change of schedule, or counting of bridges in a sports game, or any usual complication in watchmaking, or other.

However, if, preferably, the first, second and third functions concern the display of temporal magnitudes, and conventional complications, the mechanism 1 of the invention is designed to be able to perform a correction, or adjustment, of an indicator of any type, by one or more pulses, which can correct a reference or a state. As a result, the invention can also be used for the correction or adjustment of other physical quantities than those related to time, for example for a reference barometric pressure on an altimeter mechanism, the adjustment of a heading or an azimuth, the calculation of an arithmetic quantity by addition or subtraction of a value, a magnetic declination correction, the setting of a threshold of radioactivity, or other.

According to the invention, the mechanism 1 comprises a first mobile 50, which is arranged to be driven by the first control means 30. This first mobile 50 occupies either a disarming position 51 as visible on the figure 4 when the first control means 30 occupy their disarmed position 31, ie an arming position 52 when the first control means 30 occupy their armed position 32 as visible on the Figures 5 and 6 .

According to the invention, the mechanism 1 further comprises a second mobile 60, which is arranged to be driven by the second control means 40, but only when both the first mobile 50 is in its arming position 52 such that visible on Figures 5 and 6 , and the second control means 40 move from their disarmed position 41 to their control position 42, as visible on the figure 6 . Its drive by the second control means 40 is then made to an actuating position to change the position of the indicator 20.

This second mobile 60 is arranged to be maintained in a rest position in which it has no effect on the indicator 20 which it is then disengaged, when the first mobile 50 is in its disarming position 51 as visible on the figure 4 where the second mobile 60 occupies a rest position disarmed and inactive. Or the second mobile 60 is held in another rest position in which it has no effect on the indicator 20 from which it is disengaged, when the second control means 40 are in their disarmed position 41 as visible on the Figures 4 and 5 and where the second mobile 60 occupies an armed and inactive rest position. In the preferred embodiment of the figures, the transition from the disarmed and inactive rest position to the armed and inactive rest position is done by combining a translation and a pivoting, as will be explained below.

The second mobile 60 comprises a second bearing surface 63, which is arranged to cooperate, when the first mobile 50 is in its disarming position 51, in abutment with a first bearing surface 53 that includes the first mobile 50. This cooperation is done under the action of elastic return means 70, which includes the mechanism 1. These elastic return means 70 are in permanent support on a bearing surface 71, which includes the second mobile 60. And these means resilient return 70 are arranged to push the second mobile 60 to the first mobile 50, and to subject the second mobile 60 to a pivoting torque tending to move away from the indicator 20 and to bring it closer to an actuator second control means 40, in particular push-button 43 and direct rocker 44.

This direct flip-flop 44 which comprises, as the case may be, the mechanism 1 or the second control means 40, is arranged to cause in its movement, during a driving action on the part of a user, in particular by pushing on a push button 43, the second mobile 60 via a control support surface 45 that includes the second mobile 60, and to constitute, in its disarmed rest position 41, a stop limiting the pivoting stroke second mobile 60.

The second mobile 60 comprises second guide means 64, which are arranged to cooperate with first guide means 65 which are complementary to them, and which are arranged to be fixed directly or indirectly on the plate 10.

In a preferred embodiment and as visible in the figures, the second guide means 64, respectively the first complementary guide means 65, are constituted in the form of a slot 82 arranged to cooperate with an ankle 81 constituting the first means of complementary guide 65 or the second guide means 64. This pin 81 constitutes an instantaneous pivot axis of the second mobile 60.

Indeed, the second guide means 64 or the first guide means 65 preferably comprise stop means 83, 84, for limiting the relative stroke between the second guide means 64 and the first guide means 65, to the value the stroke carried by the second mobile 60 between its rest position and the actuating position in which it changes the position of the indicator 20. Preferably, these stops 83 and 84 are the ends of the light 82 which moves relative to the peg 81 preferably fixed to the plate 10. Except when the position of the first control means 30 is changed, as can be seen in FIG. figure 3 , and where the pin 81 is in an intermediate position between the stops 83 and 84, the pin 81 is, in any stable position of the second mobile 60, resting on one or other of the stops 83, as visible on the Figures 5, 6 , and 7 , or 84, as visible on the figure 4 .

To perform the correction of the indicator 20 by changing its position, the second mobile 60 comprises complementary drive means 66, which are arranged to cooperate with the drive means 22 of the indicator 20. These drive means complementary 66 are carried by a spring arm 67, which tends to apply to the drive means 22 a substantially radial steering force. The flexibility of this arm-spring 67 is useful if, for example due to an impact or the like, one arrives in tooth-to-tooth position, either between the complementary drive means 66 and the drive means 22, or between these and drive motor means that includes movement 100 for training As a result of the flexibility, the direction of the possible bracing force does not pass through a pivot axis, or by an instantaneous center of pivoting, that the indicator 20 comprises. which makes it possible, thanks to the slight change of direction of the force, to release the indicator 20.

Complementary drive means 66 impart a pulse to drive means 22, each action on second control means 40, when the first control means 30 is in the required position to allow movement thereof. These complementary drive means 66 advantageously comprise at least one tooth 660, which can cooperate with a toothed wheel, a toothed sector, a rack, or a pawl constituting the drive means 22 of the indicator 20.

• quand, tel que visible sur la figure 4, les premiers moyens de commande 30 sont en position désarmée 31, la bascule 54 est en position désarmée 51. La cheville 55 de la bascule 54 bloque alors la seconde surface d'appui 63 de la bascule 68, et limite la course de celle-ci. Les moyens de rappel 70, notamment constitués par un ressort 72, sont en appui sur la surface d'appui de rappel 71 de la bascule 68. La cheville 81 est en appui sur une butée 84 à une extrémité de la lumière 82, du côté de la tirette 54. La bascule 68 est alors parfaitement maintenue en position de repos, et les moyens d'entraînement complémentaires 66 de la bascule 68 sont à distance des moyens d'entraînement 22 de l'indicateur 20, et ne peuvent interférer avec eux.

In sum, the operation of the preferred variant illustrated by the figures is as follows:

• when, as visible on the figure 4 , the first control means 30 are in the disarmed position 31, the latch 54 is in the disarmed position 51. The peg 55 of the latch 54 then blocks the second bearing surface 63 of the latch 68, and limits the travel of this latch 68. this. The return means 70, in particular constituted by a spring 72, bear against the bearing rest surface 71 of the lever 68. The pin 81 bears against an abutment 84 at one end of the slot 82, on the the pull tab 54. The rocker 68 is then perfectly maintained in the rest position, and the complementary drive means 66 of the rocker 68 are remote from the drive means 22 of the indicator 20, and can not interfere with them. The corrective mechanism 1 is then disarmed and inactive.
• when, following an action on the control rod 33, in particular a traction action to move from a position 31 T1 crown pressed to a position 32 of traction T2 or T3 time setting by the timer, or reassembly, the first control means 30 are in the armed position 32, the latch 54 is pivoted in the armed position 52. As visible on the figure 5 , the pin 55 of the rocker 54 no longer impedes the second bearing surface 63 of the rocker 68, and allows the movement thereof, under the spring return action 72, on the bearing surface of return 71. The pin 81 bears on the stop 83 at the other end of the slot 82, on the side of the spring 72. The rocker 68 is pivoted clockwise by the spring 72 until the support of the surface control support 69 on a contact surface 45 that includes the direct latch 44, which is in the disarmed position 41. The mechanism 1 is then ready for operation. The complementary drive means 66 of the flip-flop 68 are brought close to the drive means 22 of the indicator 20. The corrective mechanism 1 is then armed and inactive.
• as visible on the figure 6 a pressing of a push-button 43 of the second control means 40 makes it possible to drive, preferably by this contact surface 45, the control support surface 69 of the flip-flop 68, which then pivots in a counter-clockwise direction around the pin 81, and provides a pulse against the spring arm 67 and with an intensity greater than the return force of the latter and the return torque applied by the spring 72 on the latch 68, to driving means complementary 66 of the flip-flop 68, which then interfere with the trajectory of the drive means 22 of the indicator 20, and leads them one step. The spring arm 67 allows the release of the tooth 660 of the toothing of the indicator 20, after having driven the latter pivotally, without triggering reverse pivoting when it leaves. The corrective mechanism 1 is then armed and active.
• the return means that comprise, or the second control means 40, or the mechanism 1, recall the direct latch 44 to the push button 43, the latch 68 is free to rotate back clockwise, and the arm -ortort 67 facilitates the output of the complementary drive means 66 relative to the drive means 22 of the indicator 20, while the spring 72, pushing the face 71 of the rocker 68, imparts a pivoting return torque clockwise around the ankle 81, bringing the rocker 68 back into its armed position, until the control surface 69 is supported on the contact surface 45 that the direct rocker 44 has, which is in return disarmed position 41. At this point, any new impulse on the push-button 43 makes it possible to drive the indicator 20 by one step.

The invention also relates to such a watch movement 100 or such a timepiece 1000, comprising, mounted directly or indirectly on the plate 10, at least one such rapid correction mechanism 1. It is understood that the same movement 100 , or the same timepiece 1000, may comprise several fast correction mechanisms 1, each intended to correct or adjust a different indicator 20.

The pin 81 and the pivot 56 of the mechanism 1 are fixed, either directly to the plate 10 of the movement 100 or the workpiece 1000, or, preferably, on an additional board itself fixed to the previous one. The entire corrector mechanism 1 is advantageously fixed on such an additional board.

In a particular construction, not illustrated here, the first control means 30 can allow, in a position T2, a first fast correction mechanism 1 to correct a first indicator 20, for example a moon phase indicator, and, in another position T3, a second fast correction mechanism 1 to correct a second indicator 20, for example a date. Elements may be common to these different fast correction mechanisms 1, for example the pull tab 54, which preferably cooperates with mechanisms located on different and parallel planes. In particular, the rod 33 is arranged to occupy several longitudinal control positions 32, and in each of them a mechanism 1 controls the correction of a particular indicator 20, for example the moon at T2 and the date at T3.

Preferably, the movement 100 comprises a movement or a chronograph mechanism, the second control means 40 comprise a push button 43 for controlling a reset mechanism of the chronograph. The chronograph movement preferably further comprises limiting means for preventing the reset of the chronograph in the event of an attempt to correct the indicator 20 during the chronograph operation, the limiting means comprising a movable finger in a bracing cooperation. on a spring, and allowing the correction of the indicator while prohibiting the reset of the chronograph, as readable in patent documents EP 2,073,077 and EP 2,073,078 in the name of OMEGA SA.

Indeed, when the chronograph reset function is used for the moon phase correction, as explained here, the normal procedure is to switch to chronograph stop mode, and perform a pre-reset, all by being in the position of push rod T1. When the rod is pulled to the T2 or T3 position, the action on the reset button 43 only makes the moon correction. A new reset is also done at the same time, since the direct flip-flop 44 which controls it is driven. But the contact hammers-hearts is maintained, nothing happens at the level of chronograph, it is a re-reset, there is no change in the chronograph status. If however the user performs an action on the push button 43 to correct the moon phase, while the chronograph is in running mode, then there is triggering of an anti-shock constituting the limitation means above, the reset is not done, but the direct flip-flop 44 acts on the flip-flop 68 and the moon is corrected. For the user, the pressure to be exerted is then stronger, about 30 N instead of 22 N of normal force on the pusher, because of a resisting force of about 8 N to overcome at the spring of the means limiting, which arms and disengages the reset means of the chronograph in this case.

As shown in the figures, and preferably, the indicator 20 is a moon phase indicator 21 which comprises a moon gear 22, with which the mechanism 1 cooperates, and which is held in position by a moon jumper 29 armed with a spring 29A. As visible on the figure 3 , a moon drive wheel 25 comprising a finger 26, mounted on a spring, drives the toothed moon disc 22, this spring allowing the disengagement of this drive to allow correction by the mechanism 1 according to the invention.

In another embodiment, the indicator 20 is a date indicator 23, and the mechanism 1 cooperates with a toothed date ring 24 for its pivoting drive. Such a ring 24 is visible on the figure 3 , is driven by a date drive wheel 27, and is held in position by a date jumper 28 armed by a spring 28A.

The invention also relates to a timepiece 1000 comprising at least one such movement 100 and / or at least one such rapid correction mechanism 1. Particularly and preferably, this timepiece 1000 is or comprises a chronograph.

In sum, the invention makes it possible to use existing mechanisms, for example the pull rod driven by the rod and the mechanism of delivery to zero of a chronograph, with the addition of a minimum number of components, which are, moreover, easy to produce and edit.
