Abstract: A mechanical horological movement includes a barrel, an escape wheel set associated with a mechanical resonator, a display wheel set configured to carry a display member including a chronograph hand and driven rotatably by the barrel, and a braking spring configured to generate a braking torque on the display wheel set when the display wheel set is subjected to a rotary drive torque to prevent trembling of the display member. The mechanical horological movement further includes an intermediate part, including a washer, located between the braking spring and an arbor of the display wheel set, the intermediate part being mounted to rotate freely on the arbor. The intermediate part and the braking spring are arranged so that the intermediate part remains stationary and non-rotating in normal operation. The braking spring overall exerts a pressing force over the intermediate part in the direction of the arbor to generate the braking torque.

Abstract: A horological movement including a setting stem, a movement winding mechanism, a date display mechanism, a time display mechanism, and a first lever carrying a drive wheel capable of being kinematically connected to the setting stem, and carrying at least one hand-setting wheel to cooperate with the time display mechanism and capable of being kinematically connected to the drive wheel, and a second lever carrying a date correction mechanism capable of being kinematically connected to the drive wheel as well as to the date display mechanism, the second lever being pivotably mounted on the first lever and arranged to move between a meshed position in which the date correction mechanism cooperates with the date display mechanism and a retracted position in which the date correction mechanism is disconnected from the date display mechanism, and the setting stem and the first lever and second lever are arranged to occupy three positions.

Abstract: A timepiece case including a middle (20) receiving a horological movement (1) having at least one function corrector (10, 12) for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement (1). The middle has a correction member (100), and a control stem (120) moving in translation within the cylindrical body of the correction member. The correction member (100) is mounted such that it slides in the middle (20) between a plurality of stable positions, each of the stable positions modifying the position of the end (122) of the control stem (120) facing the horological movement (1).

Abstract: A multifunction correction device (100) for a case (2) of a timepiece including a horological movement (1). The correction device includes: a cylindrical body (110) integral with the timepiece case (2); a primary correction module (120) moving in translation in a first direction, having a primary control member (121) integral with a primary control stem (123), which operates a first function corrector (10) of the horological movement (1); and a secondary correction module (130) moving in translation in a second direction parallel to the first direction, the secondary correction module (130) comprising a secondary control member (131) integral with a secondary control stem (133), which operates a second function corrector (12) of the horological movement (1), the cylindrical body (110) receiving the primary correction module (120) and the secondary correction module (130).

A control member (130) is capable of moving in rotation about the axis of revolution (X-X) of a control stem (120) between a plurality of angular positions and a protrusion (123) is configured such that the rotation of the control member (130) modifies the angular position of the protrusion (123) about the axis of revolution (X-X) and relative to the horological movement (1).

Abstract: A timepiece movement including a first lever bearing a first drive wheel, a second lever bearing a second wheel for time setting, and a third lever bearing a date correction mechanism. The third lever is mounted to pivot on the second lever and arranged to move between a meshing position, in which the date correction mechanism cooperates with the date display mechanism, and a retraction position, in which the date correction mechanism is disconnected from the date display mechanism.
