Abstract: The timepiece comprises a timekeeping mechanism and a switching device arranged to switch this timekeeping mechanism between two states. The switching device comprises a movable switching organ and a rotary control organ arranged to be stepwise driven in order to successively occupy a plurality of distinct angular positions about its axis of rotation. The movable switching organ and the rotary control organ respectively support a first magnetic structure and a second magnetic structure arranged so that, in a first angular position of the rotary control organ, a first magnetic force acts on the switching organ in a given direction, and so that, in a second angular position of the rotary control organ, a second magnetic force acts on the switching organ in the opposite direction.

Abstract: A sequencer mechanism including a rotatably driven locking wheel set including a peripheral holding surface of regular geometry or respectively of regular uniform magnetic polarity, arranged to hold immobile in rotation an opposite receiver wheel set, which is a reduced friction wheel including at the periphery thereof second stop elements, which are idle rollers or respectively magnets of the same polarity, cooperating in pairs with this holding surface on either side of a plane passing through the centres of the two wheel sets, the locking wheel set including a drive surface including an irregular relief portion or respectively an opposite magnetization and arranged to drive this receiver wheel set in jerks. A timepiece mechanism including such sequencer mechanism. A watch including such a timepiece mechanism and/or such a sequencer mechanism.

Abstract: A timepiece torque variator mechanism regulates the torque ratio between a first path extending about a first pivot axis and a second path about a second pivot axis. The mechanism includes a planetary element that simultaneously cooperates in a first contact area with a first path and in a second contact area with a second path. The mechanism also includes a control device arranged to adjust the radial position of the first contact area with respect to the first pivot axis and/or to adjust the radial position of the second contact area with respect to the second pivot axis.

Abstract: An automatic winding device for a spring of a watch movement including a weight fixed on a support via a bearing including a ring which drives, in only one direction of rotation called the winding direction, a transmission gear in order to wind the mainspring, this winding device wherein, on the one hand, the bearing is of the one-way type and blocks the rotation of the weight in the opposite direction to the winding direction, called the blocking direction and wherein, on the other hand, the device includes a means for decoupling the weight from said bearing in at least the blocking direction when the weight exerts on the bearing a torque higher than a desired value.

Abstract: The mechanical timepiece movement includes an escapement having a pallet-lever arranged to move alternately into abutment with two banking elements in locking periods. The pallet-lever carries at least a first permanent magnet and the timepiece movement further includes a first element and a second element of high magnetic permeability and a second magnet and a third magnet respectively integral with first and second elements of high magnetic permeability and each arranged on an opposite side to a first magnet relative to the respective elements of high magnetic permeability. This magnetic system generates, in a first part of a first half vibration of any vibration of the pallet-lever, an overall force of magnetic attraction, defining a magnetic draw additional to the mechanical draw generated by the escape wheel, and, in a second part of this first half vibration, an overall force of magnetic repulsion.

Abstract: A device that tests the chronometric precision of a watch movement or a watch includes a control device controlling a predefined cycle of motions passing through standard chronometric test positions, and a fine control device including a sequencer arranged to control the changes of chronometric test position of this movement, or respectively of this watch, in a multi-position sequence, after each measurement per position, and to start another multi-position sequence as soon as the preceding sequence finishes and which observes the predefined total duration of one cycle of several successive multi-position sequences. This sequencer is also arranged to manage the rate stabilisation durations, durations of measurement per position, and multi-position sequence durations.
