Abstract (en)
[origin: WO2018011654A1] A mechanism for selecting and actuating functions of a timepiece movement comprises a winding stem (1) ending in a crown at one of its ends. The winding stem (1) can move in rotation and axial translation, said winding stem (1) being arranged to occupy three distinct axial positions, namely a first winding position, a second position for selecting a function from among n functions in response to a rotation of the winding stem (1) about its axis, and a third position for actuating a function kinematically connected to the crown of the winding stem. The mechanism further comprises a cam wheel (7) which, when the selection mechanism is in the second position, is kinematically connected to the winding stem (1), said cam wheel (7) comprising a guiding element (8) on which n rest positions are arranged, each corresponding to a function.
