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.
