The disengaging module comprises an instantaneous drive head mounted coaxially on an axle, and a setting wheel (17) rotated around the axle by intermediate wheels that are engaged with the barrel and a ratchet. The module has a disengaging lever (14) cooperating with a cam (18) of the module, and disengaging the winding arms from the winding wheel.</p> |
