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.

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.
