Abstract
The invention relates to a timepiece movement comprising at least first and second functions implementing the display of at least first and second pieces of information. According to the invention, the movement has a selection member comprising an actuator, at least one lever configured to take at least first and second positions, respectively corresponding to the first and second functions, and respectively corresponding to the creation of first and second kinematic connections, and a cam cooperating with the actuator and the at least one lever so as to create the first and second kinematic connections.
Claims18
A timepiece movement comprising at least first and second functions implementing display of at least first and second pieces of information, the timepiece movement comprising:
- a chronograph drive wheel,
- a chronograph wheel set,
- a selection member movable between at least first and second positions, respectively associated with the first and second functions, and respectively corresponding to creation of first and second respective kinematic connections, between the chronograph drive wheel and the chronograph wheel set, resulting in opposite directions and/or different rotational speeds of the chronograph wheel set,
- wherein the selection member comprises:
- an actuator to be actuated by a user,
- a first lever configured to take at least first and second positions, respectively corresponding to the first and second functions, and respectively corresponding to the creation of first and second kinematic connections, and
- a cam cooperating with the actuator and the first lever in order to create the first and second kinematic connections,
- wherein the first lever comprises a lower plate and an upper plate between which are arranged a first gear train and a second gear train movable between the first and second positions, and
- wherein the first gear train engages with the chronograph drive wheel and is kinematically connected to the chronograph wheel set in the first position, and the second gear train engages with the chronograph drive wheel and is kinematically connected to the chronograph wheel set in the second position.
