Abstract: A timepiece movement with a movable element capable of being momentarily immobilized in any one of N discrete positions, and with a device including a lever and a first magnet integral with the lever, with N second magnets integral with the movable element and arranged along an axis of displacement, and with a magnetically permeable element arranged facing one polar end of the first magnet located on the side of the movable element. The polarity of the first magnet is reversed with respect to that of the second magnets. A first magnetic torque exerted on the lever has a first direction over a first section and a second direction, opposite to the first direction, over a second section of the distance between two successive stable positions, the first direction defining a return torque towards the movable element for a contact portion of the lever.

Abstract: A timepiece movement includes a date ring having display positions, and a device for positioning the ring in a display position. The positioning device includes a lever and a first fixed magnet, a second magnet integral with the lever and a magnetic structure integral with the ring and moving between the two magnets, this magnetic structure being formed of a magnetically permeable material and having a radial dimension that varies periodically to define periods corresponding to the distances between the display positions. The magnetic axes of the two magnets are substantially aligned and their respective polarities are opposite. The magnetic torque applied to the lever can vary, so that it is pressed against the ring in the display positions but tends to move away from the ring on one part of the angular movement between these display positions.

The spring barrel includes a drum and a motor spring to exert a driving torque which is variable as a function of the degree of winding-up of the motor spring. The equalization device is driven by the spring barrel and exerts an auxiliary torque which varies as a function of the degree of winding-up of the motor spring to counter variations in the motor torque. The equalization device includes a first and second magnetic elements being displaced from each other by exerting a magnetic force which varies as a function of the relative position of the first and second magnetic elements and produces the auxiliary torque.

Abstract: 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.
