A watch including a case (6) having a push-piece (8), movable in a radial direction, and a device (14) for locking the push-piece. The locking device includes a locking member (16) rotatably mounted about a central axis of the case and arranged to be actuated between a locking position, wherein the push-piece is stopped or blocked by the locking device so that the function cannot be activated by actuation of the control member, and an unlocking position wherein the push-piece is released and can then be actuated in said radial direction to allow the function to be activated. A rotating bezel (20) and the locking member are coaxial arranged so that they can each be rotatably actuated by the user independently of each other. Thus, the rotating bezel is independent of the locking function and can thus be dedicated to the chronograph mechanism and be in particular useful for diving.

A push button capable of improving shock resistance and a timepiece equipped therewith are provided. This push button includes an operation member having a shaft section inserted into a through hole of a case and a head section provided on the outer end of the shaft section, and an elastic member which presses the head section toward the outside of the case or is elastically deformed, and this elastic member includes a buffer section that buffers a pressure externally applied to the head section which is greater than a predetermined pressure. Accordingly, when a pressure greater than the predetermined pressure is applied to the head section, the head section comes in contact with the buffer section while elastically deforming the elastic member so as to buffer the pressure. By this structure, shock resistance is improved.

A timepiece case, including a seat which guides inside it a push-piece for supplying energy, including a control member which can be operated with pressure against resilient return device and which is integral with driving device, the push-piece or the case including a flat cam track, the case or the push-piece including a pivot about which an arm carrying a pin following the profile of this track pivots, which track includes elbows directed towards the pivot and defining stable positions of the pin and ramps arranged so that any pressure applied on the control member when it is in the rest position causes the pin to come out of its stable position and to travel, under the action of the resilient return device, towards another stable position.

A watch corrector (100) including at least one case (110) and at least one mobile element (120). In order to avoid a movement according to a degree of freedom, the at least one mobile element (120) is inserted by force, preferably, the at least one mobile element (120) includes at least one second immobilisation member (125) configured to immobilise the at least one mobile element (120) in the at least one case (110), and the at least one case (110) is inserted by force, preferably, the at least one case (110) includes at least one first immobilisation member (115) being configured to immobilise the at least one case (110) in the watch middle (200).

A winding device on a structure of a movement or watch case, including a telescopic push-piece, independent of the control stem, driving a rack for winding a barrel, and including, between a pipe fixed to the case and an operating head, first elastic return device tending to move the head away from the pipe, this head being capable of occupying an angular, longitudinal locking position corresponding to a rest position, or an angular position of freedom allowing axial mobility, or a stop position wherein it has one degree of freedom, this rack, which is movable against second elastic return device, cooperates with a winding wheel set meshing with an intermediate rack actuated by a return spring of the second elastic return device.

A push button device including a device for adjusting the angular orientation of the push button head with respect to the watch case, wherein the angular orientation adjustment device includes a friction ring disposed concentrically around the central shaft inside the tube, the friction ring rotates integrally with the central shaft and is free in translation with respect to the central shaft, the friction ring includes an external friction surface in friction contact with an internal wall of the tube, and wherein the central shaft includes a device for actuating the latter in rotation, making it possible to pivot the push button against the frictional forces generated by the friction ring, in order to adjust the angular orientation of the push button head.

To prevent an erroneous operation and improve operability, a button device and a timepiece including the button device are provided. The button device includes: a cylindrical first guide protector 11 protruding from the lateral face of a wristwatch case 1; and a first button 12 disposed in the first guide protector 11 to be slidable inward and outward of the wristwatch case 1. The first button 12 includes a first button head 13 disposed in the first guide protector 11, and a first button shaft 15 passing through a first through hole 14 of the wristwatch case 1. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1. The first guide protector 11 protects the outer periphery of the first button head 13, and this prevents accidental and erroneous operation of the first button 12. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1, and this allows the user to easily place a fingertip on the outer end face of the first button head 13, and so improves the operability of the first button 12.

A push button system for activating an actuation member, the system including a button head, a pusher actuator integral with the button head, a first hollow guide member, the pusher actuator being mounted to slide inside the first hollow guide member, the first hollow guide member being intended to be secured to a fixed element relative to the button head and to the pusher actuator, a second hollow guide member arranged in the button head, and a pin mounted to slide inside the second hollow member, and intended to be secured to the fixed element. The pusher actuator has an upper portion provided on the periphery thereof with a collar intended to cooperate with an internal face of the first hollow guide member to guide the pusher inside the member.

Watch comprising a movement with an axially and rotationally movable main stem, and a control mechanism for the remote control of the main stem which comprises a secondary stem operable by a user and guided in rotation by guide means of a plate, and axial stop means for a secondary pinion integral in rotation with the secondary stem, and a transmission train meshed with the secondary pinion to transmit any rotation of the secondary pinion to the main stem, and further comprises an articulated connection, arranged to transmit any axial motion of the secondary stem to the main stem.

A timepiece is equipped with a case that includes a case middle, a pusher, and a locking device for this pusher. The pusher is arranged movably in a translational manner in an actuation axis. The locking device contains a blocker that is movable in a translational manner along the actuation axis and with the ability to be displaced between a locking position and an unlocking position, in which positions the pusher is respectively to the locking and unlocking positions blocked and free in translation. The locking device contains in addition a control rotatably mounted in a general plane of the case between a first position and a second position corresponding respectively to the locking and unlocking positions for the blocker, this control containing structure for driving the blocker between its locking and unlocking positions.
