Timepiece comprising a device for switching a timepiece mechanism

A timepiece comprising a mechanism able to switch between a first state and a second state, a switching device for switching said mechanism between its the first state and the second state and an actuation device for actuation of said switching device;

• the switching device comprising an operating member actuated by said actuation device and a switching member, said switching member being arranged such that the switching member is capable of changing on demand from a first stable position, wherein the mechanism is in the first state, to a second stable position, wherein the mechanism is in the second state, and vice versa;
• said timepiece comprising:
• a first bipolar magnet which is fixed to said switching member so as to undergo, when said switching member changes from the first stable position to the second stable position, a motion along a switching path between a first switching position and a second switching position, and vice versa,
• a second bipolar magnet which is fixed to a support of the coupling device so as to continually offer a magnetic interaction with the first bipolar magnet between the first and second switching positions thereof, and
• at least a first highly magnetically permeable element at least partially forming said operating member;
• wherein said operating member is arranged so that, when said operating member is repeatedly actuated by the actuation device, the first highly magnetically permeable element is subjected to a back-and-forth motion between a first operating position and a second operating position;
• and wherein the switching device is arranged so that, when the first highly magnetically permeable element is in the first operating position thereof, the first and second magnets generate therebetween a force of magnetic repulsion over substantially the entire said switching path and so that, when the first highly magnetically permeable element is in the second operating position thereof, the first and second magnets generate therebetween a force of magnetic attraction on at least one part of the switching path, said part being located on the side of the second bipolar magnet.
