Abstract: A calendar date display comprises a ten-day indicator (2) and a unit indicator (1) driven by a program drive (8), which is provided with a calendar date display (9) whose toothing is engaged with the beak (15) of a lever (16) in such a way that a wheel is moved one step forward by one date number change. Between each calendar number change, the beak (15) is engaged between the first and second teeth (11, 12) of the wheel (9). At the time of the calendar number change, the beak (15) is disengaged from said first and second teeth (11, 12) in such a way that it is engaged between the second and third (12, 13) teeth of the wheel (9), thereby moving said wheel one step forward.

Abstract: The invention concerns a sound generator mechanism including a control member (10) and a mechanism (14) for locking/unlocking the control member (10), the control member (10) being able to move between a first position in which the control member is held by the locking/unlocking member (14) and in which it holds the vibrating member (12) away from the rest position thereof, and a second position wherein the control member is released by the locking/unlocking mechanism (14) and wherein it simultaneously releases the vibrating member (12), which starts to vibrate and to produce a sound.

Abstract: A pallet stone cooperates with the teeth of an escapement wheel of a watch or clock movement, and includes a trailing plane and an impulse plane and at least one capillary channel acting as a tank for a lubricant, characterized in that the capillary channel connects the trailing plane to the impulse plane.

Abstract: Instrument for measuring intervals of time including a chronograph mechanism (4) which it is possible at least to start, stop and reset to zero, said instrument (1) being characterized in that it further includes a ringing mechanism (6) which emits an acoustic signal at least when the chronograph mechanism (4) is started.

Abstract: The invention concerns a timepiece component comprising a watch movement provided with a main barrel acting as power source for a timekeeping device of the watch movement and an auxiliary barrel designed to supply mechanical power to an additional device, and mechanical control means capable of being manually actuated to trigger said additional device, characterised in that said control means are arranged to simultaneously trigger the additional device and wind the auxiliary barrel.

Abstract: The device for adjusting a time indicator includes a gear train (1), the kinematic chain of which includes a sliding pinion (2) driven by a driving wheel set (3). The sliding pinion drives a driven wheel set (4) when the driving wheel set rotates in a first direction (A) and disconnects from said driven wheel set when said driving wheel set (3) rotates in a second direction (B), opposite to the first direction. The shaft (6) that the sliding pinion (2) includes is engaged in a groove (7) having first (9) and second (12) end portions, at least the first end portion (9) of which is directed radially (R) to the driven wheel set (4).

Abstract: The mechanism (9) for triggering a striking work, is disposed between a timer (11), which is used to countdown and to display a pre-determined time interval on a dial, and a strike train (14) in order to make said striking work heard when the timer has counted down completely. The mechanism essentially comprises a lever (1) which is fitted with a leaf spring (3) and a locking stone (2).

Abstract: In order particularly to put a watch into beat and adjust the isochronism, in addition to the poising screws (2a, 2b) of the balance (1) and the fine adjusting screw (7) pressing on the index tail 20a to alter the orientation of the index (20), the device includes, on the one hand, two screws (19, 29) respectively fixed in the balance cock (10) and in the index (20) to maneuver clamps by means of L-shaped rocking elements (13, 23) to fix the end of the balance spring and define its useful length, and on the other hand, a screw (9) for immobilizing the index (20) in a determined position, these three screws (9, 19, 29) enabling a fine adjustment to be carried out.

Abstract: The present invention concerns a device for winding and setting the time of a timepiece such as a date watch (1) including a date disc (14), characterized in that the device includes a crown (12) arranged in the top plane of the watch (1) parallel to the plane of the movement (18).

Abstract: There is disclosed a chronograph mechanism capable of operating either in the conventional direct direction, or in the opposite direction to perform a countdown. The seconds counter (80) has a control finger (85) for incrementing and decrementing the minutes counter (11). In order to prevent the control finger acting at the start of a revolution of the seconds counter during a countdown, it is mounted so as to pivot on a disc (91) of the counter. Two pins (95, 96), which can be indexed and are fixed onto the disc, abut against the respective flanks of the control finger to drive it only at the end of a revolution, respectively in one direction or the other. A spring (97) keeps the finger from meshing with the transmission wheel (84) when the countdown time interval is being pre-selected.
