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.

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.

A leap-year display mechanism for a horological movement with a perpetual calendar display including a drive element connected to a month wheel set rotated by one step per month, a transmission star intended to be attached to a structure of the horological movement, arranged along the stroke of the drive element so as to be rotated thereby when the month wheel set completes one full revolution, a leap-year display connected to the transmission star via a reduction gear train so that with each revolution of the month wheel set, the leap-year display is rotated by one step.

A calendar mobile (10) indicating time information or information derived from the time, comprising at least one first obstacle element (1a, 2a, 3a) intended to receive a driving contact action driving the calendar mobile and/or intended to transmit a driving contact action from the calendar mobile, the first obstacle element being made of titanium or of titanium alloy, the mobile being a disk or the mobile having substantially the shape of a disk or the mobile having substantially the shape of a disk ring.
