Winding device with unidirectional drive arrangement

A winding device with a unidirectional drive arrangement for a watch, the device including at least one solar drive pinion mounted for free rotation about a central arbor integral with a winding wheel and arranged coaxially to said winding wheel,

• at least one toothed planetary wheel for meshing with a toothing of the solar pinion, the toothed planetary wheel being mounted for free rotation about an offset arbor parallel to the central arbor, the offset arbor being fixed to the winding wheel, and at least one hook fixedly mounted on the winding wheel,
• wherein the toothed planetary wheel is mounted for free rotation with a certain play about the offset arbor,
• wherein said device is arranged such that, in a first direction of rotation of the solar pinion, the toothing of the planetary wheel meshes with the hook to be in a locking position, such that the rotation of the solar pinion in the first direction of rotation drives the winding wheel, and wherein in a second direction of rotation opposite to the first direction of rotation, uncoupling of the planetary wheel occurs, such that the solar pinion rotates freely in the second direction of rotation without driving the winding wheel.
