A regulating device including an oscillator and capable of blocking this oscillator carried by the carriage of a tourbillon or karussel, and including a stop wheel, coaxial to the carriage wheel and limited in angular mobility by a stop pin limited by a slot of the carriage, and including a toothing engaging with an external control member for the rotation thereof, the carriage carries a resilient element arranged so as to bear against a wheel set of the oscillator to stop the latter when the control member is in an active position, and to remain remote from the carriage and from any wheel set of the oscillator when the control member is in a rest position, wherein the stop wheel is in another angular position relative to the carriage wheel.

A device for manually controlling a timepiece mechanism includes two counteracting manual corrector actuators to be operated by a user and to control a correction wheel set in opposing movements. Each actuator sets in motion an associated corrector having a beak to bear against a relief of the correction wheel set and to cause the correction wheel set to move when the actuator is moved over its full path of travel. The manual control device includes a locking lever mechanism arranged to prohibit an action of one of the actuators on the correction wheel set when the other actuator is engaged and interacting with the correction wheel set. The locking lever mechanism includes a locking lever driven in rotation during the engagement of one of the actuators to limit the travel of the other actuator and to prevent the corrector associated therewith from accessing the correction wheel set.

A horological resonator mechanism includes a structure and an anchoring unit from which at least one inertial element arranged to oscillate along a first degree of freedom in rotation about a pivoting axis extending along a first direction is suspended. The inertial element is subjected to return forces exerted by a return to make the inertial element oscillate. The mechanism includes a stopper to stop the inertial element that can be actuated on demand to prevent the oscillations of the inertial element. The stopper moves the inertial element between a pivoting position and a stopping position in which the inertial element cannot oscillate.

A selection and actuation device for at least a first and second function of a watch movement includes a translationally and rotationally movable control stem respectively selecting and actuating at least one of the functions. The control stem occupies at least first, second and third distinct, successive axial positions. An actuating lever bears first and second wheels and pinions. The actuating lever occupies a neutral position when the control stem is in one of its first and third positions, and pivots, on either side of the neutral position, between a first driving position actuating the first function responsive to control stem rotation in a first direction, and a second driving position actuating the second function responsive to a control stem rotation in a second direction. Also disclosed is a movement including such a selection and actuation device as well as to a timepiece including such a movement.

A horological mechanism (100) including a controller (300) for controlling the stopping or release of a wheel (200), and a stopping lever (10) guided on a structure (400) and which includes a first arm (16) carrying a control finger (12) that can be set by the controller, and a second arm (17) carrying a stopping finger (13) arranged to bear against the wheel (200) or to release it, and a flexible arm (15), more flexible than the first arm (16) and arranged to bear against a first fixed banking (42) of the structure (400), and which allows the movement of the stopping lever (10) in a single configuration for driving the control finger (12) by the controller pushing the control finger (12), to move the second arm (17) and stop the movement of the wheel (200).

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.

A sympathique watch (10) including a horological movement including a going train (20), a display train (30) connected to at least one display of a time value, a sympathique hand-setting mechanism and a crown (13) operated hand-setting mechanism. The sympathique hand-setting mechanism includes a coupling device (40) interposed between the going (20) and display (30) trains, the coupling device (40) being configured to adopt an uncoupled state in which it disengages the going train (20) from the display train (30) so as to allow the hands to be set on the display by means of the sympathique hand-setting mechanism, and a coupled state in which it establishes a kinematic link between the gear trains, the link allowing for sliding enabling the hands to be set on the display by means of the crown (13) operated hand-setting mechanism.
