A device for selecting a combination of patterns for a timepiece, including an inner disc including N angular sectors of the same size, each bearing a symbol on its periphery, with N being a whole number greater than 1; an outer disc coaxial to the inner disc and with a larger diameter, the outer disc bearing M symbols distributed over M*N angular sectors of the same size, with M being a whole number greater than 1, each of the M symbols of the outer disc being repeated on N consecutive sectors of the outer disc; a dial extending opposite the inner disc, the dial including an aperture allowing a pattern of the inner disc to be matched with a pattern of the outer disc; an activation device allowing the inner disc to rotate and a meshing device coupling the two discs according to a speed reducing ratio M.

The timepiece movement includes a date ring having a plurality of display positions, and a device for positioning said ring in any one of the display positions. The positioning device comprises a lever and a magnetic system formed of 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 highly magnetically permeable material and having a radial dimension that varies periodically to define a plurality of periods which correspond to the distances between the display positions. The magnetic axes of the two magnets are substantially aligned and their respective polarities are opposite. During the driving of the ring, the magnetic torque that is applied to the lever varies, 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 timepiece movement is provided with a movable element (22A) capable of being momentarily immobilised in any one of N discrete stable positions, and with a device (44) for positioning said movable element comprising a lever (26A) and a magnetic system (28) formed of a first magnet (30) integral with the lever, with N second magnets (32) integral with the movable element and arranged along an axis of displacement, and with a highly magnetically permeable element (34) 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 carrying the first magnet 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 (46) of the lever. For each of the N discrete stable positions, the first magnetic torque is applied in said first direction. In particular, the movable element is a date ring and the stable positions are date display positions.

Jumper device (80) for a timepiece device (100) including at east one first arm (81) including a first beak (81a) for positioning a first mobile unit (10), at least one second arm (82) including a second beak (82a) for positioning a second mobile unit (20), an elastic element (84) for returning the first arm and the second arm to configurations positioning the first and second mobile units, and a lever (83; 83) interfaced between, on the one hand, the elastic return element, and on the other hand, the first and second arms.

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.

A method for operating a display device (100) for displaying timepiece information, in particular time information or time-related information, the device including a first display wheel (10) (i) comprising a first disk (11) presenting first timepiece information and a first edge provided with first portions (11b) and (ii) mounted so as to pivot about a first axis (A1), and a second component (21) comprising a second edge provided with a second portion (21b) having a configuration that is at least partially complementary to a configuration of a first portion (11b); the operating method including, during at least one display jump, a first step of displacement of the first axis (A1) making it possible to displace the first display wheel (10) relative to the second edge so as to move a first portion (11b) away from the second portion (21b), starting from a rest position of the first axis (A1), a display changing step, and a second step of displacement of the first axis (A1) making it possible to displace the first display wheel (10) relative to the second edge so as to move a first portion (11b) closer to the second portion (21b), up to the rest position of the first axis (A1).
