摘要： A watch including a movement including itself an isochronous timepiece oscillator mechanism including a fixed support bearing a crosspiece carrying N primary resonators each including a weight carried by a rotating flexible bearing fixed to this crosspiece. Each primary resonator has a center of mass which, at rest, is on the virtual pivot axis of its rotating flexible bearing and is arranged to oscillate in rotation about this virtual pivot axis. The primary resonators are arranged in rotational symmetry of order N about a main axis parallel to the virtual pivot axes, and oscillating motions of any two primary resonators are phase shifted by the value of the central angle formed by their respective virtual pivot axes with the main axis.

摘要： There is provided a device for regulating the operation of a horological movement, including a magnetic escapement, which includes a resonator and a magnetic escapement mobile turning about an axis. The mobile includes at least one magnetic track with a plurality of magnets having an angular dimension that is greater than their radial dimension. The resonator includes at least one magnetic element for coupling to the magnetic track. The coupling element extends radially relative to the axis of rotation, and has a contour with a portion oriented substantially angularly when the resonator is in the rest position. When the mobile is driven in rotation, each magnet penetrates beneath the coupling element and gradually accumulates some potential magnetic energy. The magnet then exits from beneath the coupling element through the portion and the coupling element receives a pulse located around its rest position.

摘要： A simplified swing system producing mechanical vibratory movements by means of electric energy and dispensing with any active elements execpt for any energy source. Three electrodes are arranged to constitute a mechanical oscillating arrangement, one electrode of which is a resilient vibrating reed capable of oscillating by flexing and swinging toward and away from the other electrodes, a charge compensation occurring when the vibrating reed electrode approaches either one of the other two electrodes closely enough within an electric field established therebetween. In the position of rest, said electrodes are sufficiently spaced from each other but aligned face to face. When said vibrating reed is vibrated, it acts, via a movementconverting body fixed at its free vibrating end, upon a cog-wheel advanced by one tooth for each period of oscillating movement of said vibrating reed. Control means adjust the frequency of said vibrating reed and are arranged in such a way that the requirements for isochronism are met in any frequency-adjusting position of said control means.

摘要： The present invention concerns regulating members for a mechanical timepiece, specifically a system based on the magnetic interaction between a resonator, in the form of a tuning fork for example, and an escape wheel, called a “magnetic escapement”. The system is characterized in that there are several areas of magnetic interaction between the resonator and the escape wheel which are arranged such that the torques produced at the escape wheel by these interactions compensate each other if the escape wheel is not synchronized at the frequency of the resonator. This results in negligible torque in the escape wheel when the latter rotates slowly in the direction of the arrow or the opposite direction. This allows the timepiece to start with a low mainspring torque and without any start procedure or device and provides better resistance of the timepiece against a loss of synchronization in the event of a shock.

摘要： A mechanical clock movement includes a resonator, an escapement linked to the resonator, and a display of at least one item of time information. The display is driven by a mechanical drive device via a counter wheel train, the work rate of which is set by the escapement. At least the resonator is housed in a chamber, in which a reduced pressure in relation to atmospheric pressure prevails. The escapement is a magnetic escapement including an escape wheel coupled directly or indirectly to the resonator via a non-contact magnetic coupling system, wherein the magnetic coupling system is formed so that a non-magnetic wall of the chamber runs through the magnetic escapement so that a first part of the escapement is located inside the chamber whereas a second part of the escapement is located outside the chamber.
