摘要： A method for orienting a timepiece component including ferromagnetic material, where, on both ends of this component, two magnetic fields each attract it onto a pole piece, with an unbalance in the intensity of these fields around this component, in order to create a differential in the forces thereon and to press one of these ends onto a contact surface of one of the pole pieces, and to hold the other end at a distance from the other pole piece. A magnetic pivot includes such a component with two ends. It includes a guide device with surfaces of two pole pieces each generating a magnetic field attracting one of these ends, the magnetic forces exerted on the two ends being of different intensity, in order to attract only one end into contact with only one of these pole piece surfaces.

摘要： Regulating body for a wristwatch, comprising: a generator provided with a rotor and a stator with M+N coils, M being a whole number higher than, or equal to, 1; and an electronic regulating circuit having a first load impedance with an adjustable value for adjusting the current in N of said M+N coils, and therefore the rotational speed of the rotor. Only a limited number of coils is therefore used for the braking, the other coils continuing to supply the electronic regulating circuit.

摘要： A method and device for orienting a timepiece component on both ends of which two magnetic/electrostatic fields each attract it onto a pole piece, with an unbalance in the intensity of the fields around the component, in order to create a differential in the forces thereon and to press one of the ends onto a contact surface of one of the pole pieces, and to hold the other end at a distance from the other pole piece. A magnetic/electrostatic pivot includes such a component with two ends. It includes a guide device with surfaces of two pole pieces each attracted by a magnetic/electrostatic field transmitted by one of the ends, or generating a magnetic/electrostatic field attracting one of the ends, the magnetic/electrostatic forces exerted on the two ends are of different intensity, in order to attract only one end into contact with only one of the pole piece surfaces.
