A device includes a case having a case sidewall defining a circular receiver having a receiving opening and a central axis. A device body, which is waterproof in one or more applications, includes a sidewall defining a receiving aperture. A crown stem includes a push button disposed within a duct of a threaded bushing and one or more O-rings disposed about the actuation stem to allow translation of the actuation stem in the duct while preventing liquids from passing through the duct. The crown stem inserts through the aperture in the case so that the threaded bushing can hermetically seal the receiving aperture when the device body is inserted into the circular receiver to prevent the liquids from entering the receiving aperture.

The timepiece is equipped with a case which comprises 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 blocking means 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 means 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 blocking means, this control means containing means for driving the blocking means between its locking and unlocking positions.

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.

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 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 arrangement includes an electronic plate. The push-button is of the type surface mounted on a flexible printed circuit sheet that is itself partially fixed to the electronic plate. A portion of the flexible printed circuit sheet that carries the push-button remains free and is folded around a peripheral edge of the electronic plate, such that the push-button extends substantially perpendicularly to the electronic plate and bears against a lateral surface of the electronic plate.

A control device of a horological movement including a first part comprising a sliding guide tube and an activation module, and a second part slidably guided by the sliding guide tube in an axial direction relative to said first part, between an active position and an inactive position, wherein said second part comprises a slider fixed to the adjustment rod and cooperating with the activation module, and wherein the activation module includes a sheath fixed to the guide tube, cooperating with the slider and a sleeve kinematically connected with the sheath in a helical connection and being configured, under the action of an elastic member to apply mechanical stresses to the slider when the second part moves between the active position and inactive position.

A button (1) for a timepiece, comprising:a rod (4);a tube (2) for guiding of the rod (4) along a longitudinal axis (A);a ring (3); anda mechanical connection (3d, 2c, 5) between the ring and the tube, the mechanical connection being of the bayonet type and/or comprising a spring (5).

The timepiece includes a chronograph mechanism with a coupling device including an operating member and a switching member which can be switched alternately between two stable positions coupled state and uncoupled state. This timepiece includes a magnetic system formed of a first bipolar magnet fixed to the switching member, a second bipolar magnet fixed to the support of the switching device in order to continually offer a magnetic interaction with the first bipolar magnet, and at least one highly magnetically permeable element forming the operating member and able to undergo a reciprocating motion between two operating positions. The switching device is arranged so that, when the highly magnetically permeable element is in its first operating position, the two magnets generate between them a force of magnetic repulsion and so that, when the highly magnetically permeable element is in its second operating position, the two magnets generate between them a force of magnetic attraction.
