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.

A timepiece mechanism comprising a regulator, an energy distributing member a pallet fork controlled by the regulator to alternate in locking and releasing the energy distributing member, and a decoupling member elastically connected to the pallet fork and to the regulator. The decoupling member is arranged so as to oscillate between two stop elements.

A timepiece torque variator mechanism regulates the torque ratio between a first path extending about a first pivot axis and a second path about a second pivot axis. The mechanism includes a planetary element that simultaneously cooperates in a first contact area with a first path and in a second contact area with a second path. The mechanism also includes a control device arranged to adjust the radial position of the first contact area with respect to the first pivot axis and/or to adjust the radial position of the second contact area with respect to the second pivot axis.

The mechanical timepiece movement with power reserve indication comprises at least one barrel system connected to a winding wheel of a differential gear and an unwinding wheel of the differential gear. An intermediate wheel of the differential gear is connected to a cam wheel set to drive it in rotation via a reducing stage. A rack, which acts on a power reserve indicator, is in contact with the cam wheel set. When the power reserve is at zero, a locking part of the rack comes into contact with a locking member to lock the movement at an unwinding output of the barrel system or in contact with the unwinding wheel of the differential gear.
