Abstract: The invention concerns a timepiece. Such timepiece comprises: a horometric movement (1) including a motor pinion or intermediate wheel (2), a crown wheel with interior teeth (6) associated with a first display system, such as a date display, and a jumper spring (8), a driving wheel set (10) including a drive wheel (12) controlled by the motor pinion (2) and transmitting a motor couple received from the motor pinion to the crown (6) through a salient tooth (14), such wheel set (10) additionally including a hub (16) which is mounted to rotate freely relative to the movement and which elastically supports the drive wheel (12) through an elastic arm (22), such timepiece being characterized in that the elastic arm (22) which supports the drive wheel (12) has a basically C form winding around the hub (16), while the drive wheel (12) meshes directly with the motor pinion (2). The invention is applicable to a timepiece of the mechanical or electromechanical type.

Abstract: This invention concerns a timepiece of the mechanical and/or electromechanical type. Such piece comprises a first display mechanism (1), in particular a date display, a second display mechanism (2) such as a moon phase display, rapid correction means (4) for both display mechanisms (1, 2) and a driving organ (6) which controls such display mechanisms (1, 2) and which can absorb equally the displacement of one or the other of these mechanisms, such piece being characterized in that the rapid correction means (4) comprises meshing means (64) common to both mechanisms (1, 2), mounted for rotation and adapted to operate alternatively upon one or the other of such two mechanisms (1, 2) under the action of control means (72, 74). This invention is applicable to calendar and moon phase watches having a center date hand.

Abstract: The present invention relates to a timepiece of the electromechanical type.This invention has a movement provided with control means such as an electronic circuit connected with a resonator, a source of electrical energy, and in particular battery, and electrical connection means to connect this battery to the control means via the intermediary of a first supply path wherein the electrical connection means also supply a second parallel supply path which is capable of providing a substantially permanent and reliable connection between at least one of the poles of the battery and the control means.This invention has applications in any electromechanical timepiece such as, for example, a wristwatch.
