A watch is formed by a mechanical movement incorporating a mechanical resonator. The watch comprises a display displaying the time and a correction device for correcting the displayed time, which is formed by a receiver for receiving an external correction signal which is supplied by an external electronic device (in particular a mobile phone), a braking device for braking the mechanical resonator and an electronic controller. The correction device is arranged such that it can correct the time displayed as a function of a time error (loss or gain) contained in the external correction signal. For this purpose, the correction device is arranged such that the braking device can act on the mechanical resonator during a correction period to vary the running of the drive mechanism of the display, in order to correct at least for the most part the time error in the time displayed.

A watch formed by a mechanical movement incorporating a mechanical resonator, including a display displaying the actual time, a correction device formed by a device for detecting the passage of at least one hand through at least one reference time position and by an electronic correction circuit allowing an overall time error for the display to be determined, and a device for braking the mechanical resonator. The correction device is arranged such that it can correct the actual time displayed as a function of the overall time error (loss or gain) previously determined. For this purpose, the correction device is arranged such that the braking device can act on the mechanical resonator during a correction period to vary the running of the drive mechanism of the display, in order to correct the actual time displayed.

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.

A sympathique watch (10) including a horological movement including a going train (20), a display train (30) connected to at least one display of a time value, a sympathique hand-setting mechanism and a crown (13) operated hand-setting mechanism. The sympathique hand-setting mechanism includes a coupling device (40) interposed between the going (20) and display (30) trains, the coupling device (40) being configured to adopt an uncoupled state in which it disengages the going train (20) from the display train (30) so as to allow the hands to be set on the display by means of the sympathique hand-setting mechanism, and a coupled state in which it establishes a kinematic link between the gear trains, the link allowing for sliding enabling the hands to be set on the display by means of the crown (13) operated hand-setting mechanism.

A sympathetic timepiece assembly (1000), which includes a clock (100) and at least one watch (200) arranged to be deposited in a receptacle 150 included in the clock, in a single transfer position, this sympathetic assembly (1000) including a connection mechanism between the clock (100) and each watch (200) when the watch (200) is deposited in the receptacle 150 in the transfer position, this connection mechanism includes at least two separate transmission lines, one for transferring power or movement, and the other for selecting a function to be performed or a display variable to be adjusted.

Method for relative time setting of a sympathetic watch (200) by a sympathetic clock (100) with which the watch (200) forms a sympathetic assembly (1000), the watch (200) including at least one hour display (4) and one minute display (5), a reference position of which will be defined, and the time-setting is executed, only at request by action of a user on a control means (300) included in the clock (100) or the watch (200), or automatically periodically controlled by the clock (100), and, to perform the relative time setting, the clock (100) drives said displays (4; 5) of the watch backwards, in the counter-clockwise direction, with a sufficiently long stroke to ensure that the displays (4; 5) pass through the reference position, before a return in the clockwise direction to the instantaneous time, and method for winding the watch by this relative time setting.

A method for reference time setting of the displays (4; 5) of a sympathetic watch (200) by a sympathetic clock (100) forming a sympathetic assembly (1000) with the watch (200) which includes a coupling mechanism (706) between its display and finishing gear trains, and a hammer (701) movable between a coiled position where it is retained by a pawl, and an active position where it rests on an hour heart cam (702) carried by an hour wheel (708) of said watch (200), to constrain it in rotation to its smallest radius.

The invention relates to a method for step-by-step time setting of a sympathetic watch (200) by a sympathetic clock (100), forming together a sympathetic assembly, where a predetermined time-setting step and a reference position of the displays (3; 4; 5) of the watch (200) are determined, and where the clock (100) performs the time setting of the watch (200) by positioning a transmission line in a position corresponding to the time setting, and by actuating, in successive steps, each of the value of the predetermined step, a transmission line capable of imparting to a time-setting mechanism internal to the watch (200) any movement necessary to precisely achieve the display of the current time.

A method for reference time setting of the displays of a sympathetic watch by a sympathetic clock forming a sympathetic assembly with the watch. At any time, the reference time setting of the watch is performed by a first phase during which the placement in the reference position is triggered, by a first displacement of an interface between the clock and the watch, the reference time setting of the displays, and the coupling mechanism is uncoupled to allow the rack to drive the display gear train of the watch in the counter-clockwise direction, over as many revolutions as necessary, until the pawl meets the ratchet tooth opening of the hour cam, then the time-setting mechanism controlled by the clock sets the time of the displays of the watch in the clockwise direction to the exact time by recoiling the rack, then the coupling mechanism is recoupled.

A method for acquiring data on a sympathetic clock (100) for setting the time of a sympathetic watch (200) at request. The sympathetic watch forms with the clock (100) a sympathetic assembly (1000). The watch includes an hour display (4) and a minute display (5), a reference position of which will be defined at a reference time, and the clock (100) performs the time setting of the watch (200), either when the watch (200) is placed on the clock (100), or alternatively at a predetermined time on the clock (100), or at request by action of a user on a control means (300) included in the clock (100) or the watch (200), or upon control of a horological movement (900) included in the clock (100).
