Sympathetic timepiece assembly

A method for step-by-step time setting of a sympathetic watch (200) by a sympathetic clock (100) forming together a sympathetic assembly (1000) including a mechanism for connection with at least two distinct transmission lines between said clock (100) and said watch (200), one for power or movement transfer, and the other for selecting a function to be performed or a display variable to be adjusted, each transmission line including an interface with a clock actuator in said clock (100) and at least one watch actuator in said watch (200), and active when said watch (200) is deposited in a receptacle (150) included in said clock (100), in a transfer position, said watch (200) including at least one resonator (10), and display and finishing gear trains, and, either a stop mechanism (20) arranged to stop the operation of said resonator (10), or a coupling mechanism allowing to separate the display from the finishing gear train, or else both such a stop mechanism (20) and such a coupling mechanism, and said watch (200) including at least one hour display (4) and one minute display (5), a reference position of which will be defined, wherein said clock (100) performs the time setting of said watch (200), either when said watch (200) is placed on said receptacle (150), or when switching to a predetermined instant on said clock (100), or upon control of a horological movement (900) included in said clock (100), and wherein a predetermined time-setting step value is determined and said clock (100) positions a said transmission line in a position corresponding to the time setting, and actuates, in successive steps, each of the value of said predetermined step, a second said transmission line capable of imparting to a time-setting mechanism internal to said watch (200) any movement necessary to precisely achieve the display of at current time.
