1. A method for acquiring data on a sympathetic clock (100) for setting the time of a sympathetic watch (200) at request, said sympathetic watch forms with said clock (100) a sympathetic assembly (1000) including a connection mechanism including at least a first and a second distinct transmission line between said clock (100) and said watch (200) 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 a display gear train and a finishing gear train, 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 at a reference time, wherein said clock (100) performs the time setting of said watch (200), either when said watch (200) is placed on said receptacle (150), or alternatively at a predetermined time on said clock (100), or upon control of a horological movement (900) included in said clock (100), and wherein the time displayed by said clock (100) is read for transmission of time information to said watch (200), by implementing a reading mechanism, included in said clock (100), which reads a deviation between a current time compared to said reference time, and which is arranged to transmit the information of the value of this deviation to said watch (200), so as to index the watch after placing said displays (4; 5) in said reference position.
