ABSTRACT:
A timepiece with a control pinion loosely mounted on the stem of the timepiece. A spring urges the pinion to move axially on the stem. A coupling device is operable between the stem and the pinion to render the same angularly rigid with respect to each other. In one axial position of the stem, the pinion is moved to meshed engagement with an element of the timepiece which it is desired to be operated manually.
