Abstract: A variation reduction mechanism of a stop position of a pointer includes a return gear that is driven in conjunction with a time display mechanism, a slip torque spring (friction member) that contacts the return gear to apply a friction force to the return gear to be driven, and a return spring (return spring member) that applies, to the slip torque spring, a torque of the return gear in a direction (dashed line arrow—R direction) opposite to a normal hand movement direction (arrow R direction).

Abstract: The invention relates to a mechanism for displaying an information for a timepiece, comprising a mobile (10) intended to be driven in rotation by the movement of the timepiece about a display axis (17), a satellite (20) pivoted on the mobile (10) about a satellite axis (27) parallel to the display axis (17) and remote from a non-zero distance d1 thereof, a display area (80), an indicator (50) secured to the satellite (20) and the position of which relative to the display area (80) provides the information, and a crown (30) centered on the display axis (17) and kinematically connected to the satellite (20). The mechanism is particular in that the indicator (50) is located at a distance d2 from the satellite axis (27), which is greater than or equal to the distance d1.

Abstract: A method for reference time setting of the displays (4; 5) of a sympathetic watch (200) by a sympathetic clock (100) forming a sympathetic assembly (1000) with the watch (200) which includes a coupling mechanism (706) between its display and finishing gear trains, and a hammer (701) movable between a coiled position where it is retained by a pawl, and an active position where it rests on an hour heart cam (702) carried by an hour wheel (708) of said watch (200), to constrain it in rotation to its smallest radius.

Abstract: A horological display mechanism with an elastic hand (1) for driving, about a shaft (D), pipes mounted at the ends of a flexible blade (3), arranged to deform the flexible blade (3), including a mechanism acting on the drive train of the first pipe (2) and of the second pipe (4) and which includes two planetary wheels (82; 84) for driving the pipes (2; 4), and an input planet-carrier chassis (180) for driving the hand (1), and rotatable with a regulation cam (801), the track (802) of which includes a rising edge and falling edge. An elastic arm (803) has a distal end which cooperates with the track and a rising edge of which raises the elastic arm (803) away from the axis of the cam to consume torque, and a falling edge which makes the elastic arm move back towards the axis to restore torque to the system.

Abstract: A horological movement including a seconds wheel set, a power source, and a regulator (13) to regulate the motion of the seconds wheel set. The movement includes a control mechanism (20) to take an active state wherein it cooperates with the regulator (13) to immobilise it and with the seconds wheel set for driving it such that it rotates into a predefined position. The control mechanism (20) is adapted to take an inactive state wherein it releases the regulator (13) such that the latter is able to regulate the motion of the seconds wheel set, and the seconds wheel set so as to authorise the displacement thereof. The mechanism (20) includes two motion transmitting modules, each to be connected to a specific actuating member, and each being driving the control mechanism (20) between the inactive state and active state upon operation of the actuating member to which it is connected.

Abstract: A device (1) for displaying a succession of indications of a time variable for a timepiece, this display device (1) including an indicator which carries the succession of indications of the time variable to be displayed, and is arranged to be driven by a horological movement to move from an initial position to a final position through a succession of intermediate positions in which the display of the time variable passes from one indication to the next indication at a required frequency. Also included is a mechanism (22; 72) for positioning the indicator in a reference position and an actuating device, the mechanism including a cam on which acts, when actuated, the actuating device such that the mechanism brings the indicator back to its predetermined reference position.
