A method for operating a counting device (90), such as a countdown device, or a timepiece movement (100) or a timepiece (200), the method including performing a first action on a first control member (C1) causing a first timepiece function to be returned to an initial state, and then performing a second action on the first control member (C1) causing an action of adjusting or winding a second timepiece function.

A timepiece transmission mechanism, with a differential mechanism with inputs or outputs including a first wheel set cooperating with a first train and a second wheel set cooperating with a second train, this differential mechanism kinematically connecting the first wheel set and second wheel set in the coupling position, and separating them in the uncoupling position, the first wheel set carrying a planet wheel set which meshes with a toothing of an arbor integral in rotation with the second wheel set, and with a crown-wheel forming another input or output of the differential mechanism, which includes control means arranged to lock or release the crown-wheel to perform the coupling or the uncoupling function, depending on the position given to the control means by a selector arranged to cooperate with an actuator of a timepiece movement, or to be operated by a user.

A mechanism for stopping (100) or releasing a regulating or chronograph mechanism wheel (1) in rotation about a main axis (D), including a control organ (210) operable by a user and linked with a stopping lever (2) including a support surface (20) arranged to cooperate with a complementary support surface (11) of the wheel (1), and movable between a working position where any support surface (20) is distant from the complementary support surface (11), and a stopping position where a support surface (20) is bearing thereon. Also, a timepiece (1000) including regulating or chronograph mechanism including such a stopping mechanism (100).

The timepiece includes a chronograph mechanism with a coupling device including an operating member and a switching member which can be switched alternately between two stable positions coupled state and uncoupled state. This timepiece includes a magnetic system formed of a first bipolar magnet fixed to the switching member, a second bipolar magnet fixed to the support of the switching device in order to continually offer a magnetic interaction with the first bipolar magnet, and at least one highly magnetically permeable element forming the operating member and able to undergo a reciprocating motion between two operating positions. The switching device is arranged so that, when the highly magnetically permeable element is in its first operating position, the two magnets generate between them a force of magnetic repulsion and so that, when the highly magnetically permeable element is in its second operating position, the two magnets generate between them a force of magnetic attraction.
