Abstract

A sympatique watch ( 30 ), including a horological movement to which are connected a watch hour ( 31 ) and minute display ( 32 ), including a barrel ( 33 ), a resonator ( 34 ), a time-setting mechanism, a coupling mechanism ( 38 ) to separate a display train ( 35 ) and a finishing train ( 36 ), a stop mechanism ( 37 ) of a resonator ( 34 ), and a reset mechanism to move each hour ( 31 ) and minute display ( 32 ) in a predetermined reference position. The watch includes a first and a second actuator ( 310, 320 ) cooperating with a first and a second actuator ( 210, 220 ) of the clock ( 20 ). The first actuator can occupy three successive distinct positions to act on the coupling mechanism ( 38 ), the stop mechanism ( 37 ) and the reset mechanism. The second actuator can occupy two end positions alternately to act on the time-setting mechanism, only when the first actuator ( 310 ) occupies one of its successive distinct positions.

3 . The watch ( 30 ) according to claim 2 , wherein the first actuator ( 310 ) of the watch ( 30 ) is configured to act on the coupling mechanism ( 38 ), on the stop mechanism ( 37 ) and on the reset mechanism by means of a transmission lever ( 39 ) to which the first actuator is connected, said transmission lever being configured to concomitantly bias the coupling mechanism ( 38 ) and the reset mechanism.

4 . The watch ( 30 ) according to claim 3 , wherein the transmission lever ( 39 ) extends between a first end of said lever at which said lever is rotatable and a second end including an excrescence ( 395 ) whereby said transmission lever ( 39 ) cooperates with the reset mechanism, with the coupling mechanism ( 38 ) and with the stop mechanism ( 37 ).

5 . The watch ( 30 ) according to claim 3 , wherein the transmission lever ( 39 ) is subjected to a return force by a lever spring tending to move the transmission lever to an initial position wherein the transmission lever drives the reset mechanism to an inactive position, the coupling mechanism ( 38 ) to a coupling position and the stop mechanism ( 37 ) to a position wherein the stop mechanism releases the resonator ( 34 ).

6 . The watch ( 30 ) according to claim 3 , wherein the coupling mechanism ( 38 ) includes two arms ( 380 , 381 ) forming pliers, and a friction spring ( 383 ) tending to move the finishing train ( 36 ) engaged with the display train ( 35 ), the arms ( 380 , 381 ) being biased by a coupling spring ( 382 ) towards a coupling position and being configured so that when the first actuator ( 310 ) occupies a first position, the arms are driven against the coupling spring ( 382 ), in an uncoupling position wherein the arms oppose an action of the coupling spring ( 382 ) and of the friction spring ( 383 ) in order to move said finishing train ( 36 ) away from the display train ( 35 ), and wherein the arms ( 380 , 381 ) cooperate with one another at an interface area whereby one of the arms, corresponding to a first arm, is capable of forcing the other arm, corresponding to a second arm, to move towards the coupling position under the effect of the return force generated by the coupling spring ( 382 ), and whereby the second arm ( 381 ) is capable of transmitting to the first arm ( 380 ) a force to which the first arm is subjected by the transmission lever ( 39 ) when the first actuator ( 310 ) occupies the first position, the force moving said arms ( 380 , 381 ) in the uncoupling position.

7 . The watch ( 30 ) according to claim 3 , wherein the reset mechanism includes at least one heart-piece cam ( 390 ) integral in rotation with the time value display ( 31 , 32 ) and at least one hammer ( 391 ) arranged to bearingly cooperate with said at least one heart-piece cam ( 390 ) under an action of a hammer spring ( 392 ), so as to occupy an active position and force in rotation said heart-piece cam ( 390 ) until the heart-piece cam is bearing against a smallest radius thereof, when the first actuator ( 310 ) occupies a first position, the hammer ( 391 ) being configured to be returned and held in an inactive position by the transmission lever ( 39 ), wherein the transmission lever is moved away from said heart-piece cam ( 390 ), when the first actuator ( 310 ) occupies another position.
