Abstract

This device is specified for a wrist watch, comprising at least one bi-directional electric motor, at least one mechanism coupled to this motor to drive a day disk (12) and a date disk (10), and at least one electronic circuit designed to transmit control impulses to this motor. This mechanism comprises a drive wheel (11) coupled to the motor and two date fingers (14, 15) pivoting respectively on two axes (16, 17) borne by said drive wheel (11) to increment, and decrement respectively, the date disk (10). The drive wheel (11) also bears a control wheel (22) for a day star (13) designed to increment, or respectively decrement, the day disk (12) by means of said day star (13). The control wheel (22) for the day star is concentric with the drive wheel (11) and integral with the latter when it rotates in one direction or the other.
