The invention concerns a watch comprising a case having a middle part and inside which is housed a movement. The watch also includes a control member intended to be actuated by a user and an internal transmission device provided with an actuator, able to move, in response to actuation of the control member, between a rest position and an active position in which it actuates a mechanism of the movement. In an original manner, the transmission device includes a closed cavity filled with a fluid and a thrust means kinematically connected to the control member and arranged to displace the fluid inside the cavity, the displacement of fluid inside the cavity causing displacement of the actuator.

Elementary timepiece mechanism comprising a first housing about an axis, a second housing, and a mobile element comprising a first shoulder pivoting in the first housing and a second shoulder pivoting in the second housing, the second housing comprising at least a first abutment surface arranged to ensure the alignment of the mobile element on said axis when the mobile element is in abutment on the first abutment surface, and the elementary mechanism includes at least one elastic return means arranged to return the mobile element to this first abutment surface.

A minute hand of a timepiece has a central arbor, on which, for driving around the same: a gearwheel is fixed in a first accommodating region, a flyback device is fixed in a second accommodating region, and a snail cam is arranged with an interference fit in a third accommodating region. The snail cam has an opening for accommodating the head of an eccentric and the flyback device has an opening for accommodating the finger of the eccentric, and therefore rotation of the eccentric head, via the flyback device fixed on the central arbor, makes it possible to rotate the snail cam by an angle about the central arbor relative to the gearwheel for setting the triggering point of the advancement operation by the minute control level.

Elementary timepiece mechanism comprising a first housing about an axis, a second housing, and a mobile element comprising a first shoulder pivoting in the first housing and a second shoulder pivoting in the second housing, the second housing comprising at least a first abutment surface arranged to ensure the alignment of the mobile element on said axis when the mobile element is in abutment on the first abutment surface, and the elementary mechanism includes at least one elastic return means arranged to return the mobile element to this first abutment surface.

Timepiece wheel set (1) including an arbor (3) carrying a wheel (4), and a heart cam (2) in an angularly indexed position with respect to the wheel (4), the heart cam (2) is freely mounted in a radial direction (R) with respect to the axis (D) of the arbor (3), and is returned in a neutral position towards the axis (D) by at least one flexible element (6), which is either a strip (25; 26) incorporated in the heart cam (2), or a spring (60) inserted between the wheel (4) and the heart cam (2), and the flexible element (6) is dimensioned to damp impacts applied to a peripheral cam track (23) comprised in the heart cam (2).

A chronograph mechanism including an energy accumulator, a regulating system, a chronograph counter train including a minute-counter having a minute wheel set and at least one minute indicator member, and a seconds-counter having a seconds wheel set and a seconds indicator member, a chronograph zero-reset mechanism including a minute zero-reset mechanism. The minute zero-reset mechanism is arranged to cooperate with the minute wheel set, the minute indicator member being permanently integral with the minute wheel set, and the chronograph counter train includes an uncoupling device between the minute-counter and the seconds-counter, arranged to kinematically connect the minute wheel set and the seconds wheel set during the counting and to uncouple the seconds wheel set from the minute wheel set when the chronograph mechanism is reset to zero.

A horological movement including a running train driven by a first energy source; a regulating member for regulating the running train; a chronograph mechanism including a chronograph train driven by a second energy source; a coupling configured to couple the chronograph train, on demand, to the regulating member to regulate the chronograph train using the regulating member; a chronograph start/stop control device cooperating with the coupling; wherein the coupling is a differential coupling including a first input wheel driven by the running train and having a rotational speed that is regulated by the regulating member; an output wheel meshed with the chronograph train; a second idle input wheel cooperating directly or indirectly with the chronograph start/stop control device; the coupling including a drive assembly configured to rotate the output wheel at the rotational speed regulated by the regulating member.

The present disclosure relates to a chronograph-watch comprising a timepiece mechanism. The timepiece mechanism includes: a current time mobile comprising an axis and being arranged to rotate about this axis, a first mobile comprising an axis and being arranged to be connected to the current time mobile, an indicator member, a second mobile arranged to mesh with the first mobile and to be connected to the said indicator member, an element bearing a scale comprising a set of indications, the indicator member allowing information to be displayed on this scale. The mobiles are arranged so as to obtain a gear ratio between the mobiles which varies as a function of their relative angular position, so that the indicator member rotates with a variable rotational speed in correspondence with at least one subset of said set of indications.

A control device is disclosed, which comprises: a lever movable between a rest position and a triggering position, a spring arranged to return the lever in its rest position, an actuating member movable between a neutral position and an actuating position in which it actuates a watch mechanism, a mechanical energy storage member interposed between the lever and the actuating member in such a way that it is charged when the lever moves towards its triggering position, and can be discharged when the lever reaches its triggering position by moving the actuating member towards its actuating position, the device comprising a locking member intended to release the actuating member only when the lever reaches its triggering position.

The present disclosure concerns a watch mechanism having, in a main plane: an actuating device, a pivoting piece arranged to pivot under the action of the actuating device around an axis perpendicular to the main plane, a rigid piece, a first flexible blade connecting the rigid piece to the pivoting piece, a mechanical pivot having a main axis offset in the main plane from the axis of rotation of at least one of the pivoting piece and the rigid piece, the pivoting piece being mounted on said mechanical pivot, which preloads the first flexible blade and makes the assembly formed by the rigid piece and the first flexible blade bistable, so that the rotating pivoting piece causes the bistable assembly to move in the main plane, from a first stable position, to a second stable position.
