Abstract (en)
[origin: EP2634650A2] The mechanism has an oscillating mass (2), and a mobile (15) with a sawtooth wheel (14) and intended to actuate a winding ratchet (25) of a clock movement and two pawls (12a, 12b). The pawls co-operate with the wheel to alternatively move the mobile under the effect of oscillation of the oscillating mass. The mobile includes disengaging devices intended to uncouple the wheel from the winding ratchet during manual reassembly of the clock movement. The disengaging devices are located in a cavity defined by the wheel.
