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.

A time measurement device includes: a higher-digit indication hand that is configured to indicate a higher digit of a measured time; a lower-digit indication hand that is configured to reciprocate and indicate a lower digit of the measured time on a forward route and on a return route; a first drive unit that is configured to drive the higher-digit indication hand; a second drive unit that is configured to drive the lower-digit indication hand; a time counter that is configured to measure a time; a first drive controller that is configured to control the first drive unit to drive the higher-digit indication hand based on the measured time measured by the time counter; and a second drive controller that is configured to control the second drive unit to drive the lower-digit indication hand based on the measured time measured by the time counter, the second drive controller reciprocating the lower-digit indication hand at a predetermined period, and the first drive controller moving the higher-digit indication hand at a time interval equal to or less than a half of the predetermined period.

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.

The present disclosure relates to a watch mechanism having a first actuating device, a second actuating device, a first pivoting piece arranged to cooperate with the first actuating device and to pivot about a first axis perpendicular to a first principal plane, a second pivoting piece arranged to be connected to the first pivoting piece and to pivot about a second axis to a second main plane, a first flexible blade being connected to each pivoting piece, a mechanical pivot having a main axis offset in the first main plane and/or in the second main plane from the axis of rotation of the first pivoting piece and the second pivoting piece, the first pivoting piece and the second pivoting piece being mounted on said mechanical pivot, thereby preloading the first flexible blades.

The invention relates to a chronograph mechanism (1; 201), for a timepiece movement, including a counter for a unit of time comprising:a display wheel capable of being rotated from a zero position,a return wheel, rotatable between an initial position, associated with the zero position of the display wheel, and a final position, the display wheel and the return wheel being arranged such that the return wheel pivots from its initial position to its final position when the display wheel makes one revolution,a resilient return member (20) arranged to act on the return wheel and to tend to return it to its initial position, the display wheel including a toothing arranged in mesh with the return wheel and having a truncated portion intended to allow the display wheel and the return wheel to be uncoupled on each complete revolution of the display wheel.

A mechanism for stopping (100) or releasing a regulating or chronograph mechanism wheel (1) in rotation about a main axis (D), including a control organ (210) operable by a user and linked with a stopping lever (2) including a support surface (20) arranged to cooperate with a complementary support surface (11) of the wheel (1), and movable between a working position where any support surface (20) is distant from the complementary support surface (11), and a stopping position where a support surface (20) is bearing thereon. Also, a timepiece (1000) including regulating or chronograph mechanism including such a stopping mechanism (100).
