Provided is a timepiece case that does not require a seal ring, such as an O ring, that is made of a resin material. The timepiece case includes a case body configured from metallic glass; and a button part that is formed integrally with the case body and is flexible.

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 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.

A Dewar device for mechanical and/or functional components of a watch, the device being provided with a bracelet and a casing including an enclosure wherein a case of the watch can be disposed so that a crystal of the case is arranged opposite a crystal of all the elements of the casing defining this enclosure and at least one fastening device fastening the watch case in the enclosure of the casing by keeping it remote from all the elements of the casing defining this enclosure, the Dewar device including a device for actuating at least one push button by rotating a pivoting bezel of the casing.

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.

A timepiece including a case middle, a bezel, rotatably mounted on the case middle, and an actuation member including a cover capable of adopting a retracted position and a deployed position relative to the case middle, the cover being provided with a bearing surface actuatable by the user's finger, wherein the cover includes a shoulder distinct from the bearing surface, the shoulder being intended to cooperate with the bezel when the cover is in the retracted position.

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 control module (10) for an electronic device including a push-button (11) including a striker element (111), a switch (12) adapted to occupy a connected state and a rest state, said striker element (111) being configured to drive the switch (12) into one or the other of the connected and rest states, the control module further comprising a stop member (13) against which the striker element (111) comes to bear when it drives the switch (12) into the connected state or into the rest state.

A tool for actuating a corrector push-button fitted in a small portable object, wherein this actuation tool includes a body which extends between a rear end which defines a gripping zone of the actuation tool and a front end which defines an actuation zone of the actuation tool, at least the front end of the actuation tool being magnetised.

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.
