Abstract:
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.
