Zusammenfassung:	The device has a wheel (7) and another clutch wheel (17) that are coaxial coupled to each other in rotation in a direction using Breguet teeth (21, 22). The latter clutch wheel is mobile in an axial direction and solicited by a return spring (26) engaging the Breguet teeth. The latter clutch wheel is fixed on a sliding axle (18) that is mounted in a rotational and sliding manner in fixed bearings. The return spring includes an elastic strip supported against an end of the sliding axle. The fixed bearings are formed by clock jewels (24, 25). An independent claim is also included for a watch movement comprising an automatic remounting mechanism.
