Selection and actuation device for a plurality of functions of a watch movement

A selection and actuation device for a plurality of functions of a watch movement comprising at least a first function of a first mechanism of the movement and a second function of a second mechanism of the movement, said device comprising a translationally and rotationally movable control stem for respectively selecting and actuating at least one or the other of said functions, said control stem being arranged to be capable of occupying at least first, second and third distinct, successive axial positions, said device comprising means for actuating at least the first and the second functions, which means are arranged to be kinematically linked to the control stem such that one of the first and second functions can be actuated after having been selected solely by an axial translational movement of the control stem from the control stem's first position to the control stem's second position, and such that the other of the first and second functions can be actuated after having been selected solely by an axial translational movement of the control stem from the control stem's third position to the control stem's second position,

• wherein the means for actuating at least the first function and the second function comprise an actuating lever bearing at least a first wheel and pinion and a second wheel and pinion, said actuating lever being arranged to be capable of occupying a neutral position when the control stem is in one of the control stem's first and third positions, and to be capable of pivoting, on either side of said neutral position, between a first driving position in which said first wheel and pinion (18) is kinematically linked to the control stem in order to be capable of actuating at least the first function in response to a rotation of the control stem in at least a first direction and a second driving position in which said second wheel and pinion is kinematically linked to the control stem in order to be capable of actuating at least the second function in response to a rotation of the control stem in at least a second direction, identical to or different from the first direction, said actuating lever being arranged to pivot into the actuating lever's first driving position when the first function is selected and to pivot into the actuating lever's second driving position when the second function is selected.
