An electronic device is provided in the disclosure. An electronic device includes a frame, a stop pin, and a button. The frame defines a button hole and a pin hole in communication with the button hole. An inner side wall of the button hole is provided with a stop protrusion at a position away from the pin hole. The stop pin is inserted into the pin hole and partially received in the button hole. The button is provided with a first hook and a second hook away from the first hook. The first hook hooks the stop protrusion. The second hook hooks part of the stop pin in the button hole. The button can be pressed to slide a preset distance under a limit of the stop pin and the stop protrusion.

A platinum alloy consisting, by weight, of the following elements: 95.00 to 96.00% of Pt, 1.00 to 4.95% of Ru, 0.05 to 2.00% of Ge, 0 to 2.00% of Au, any impurities with a total content 0.50%.

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 Dewar device for mechanical and/or functional components of a watch, this device including a wristlet, a case including a chamber wherein a case of the watch is capable of being disposed in such a way that a glass of this case is arranged facing a glass of a set of elements of the case defining this chamber, at least one fastening device fastening this watch case in this chamber of the case while maintaining it distant from all of the elements of the case defining this chamber, and a device for actuating at least one push button by the angular movement of a free end of at least one lever element of this device relative to the case, this at least one lever element having another end movably fastened to this case.

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 present invention relates to a control device (10) for a horological movement including, on the one hand, a first part (100) comprising a sliding guide tube (101) intended to be fixed relative to said horological movement and an activation module (120), and on the other hand, a second movable part (200) slidably guided by the guide tube (101) in a direction called “axial direction”, relative to said first part (100), between an active position wherein it is able to be integral, by means of an adjustment rod (201), with a component of the horological movement, and an inactive position wherein said adjustment rod (201) is intended to release the component of the horological movement, said second part (200) comprising a slider (202) fixed to the adjustment rod (201) and cooperating with the activation module (120) so that they exert mechanical stresses on each other when the second part (200) moves between the active and inactive positions, and so that these mechanical stresses are released when the second part (200) reaches one of the active or inactive positions.

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 device including a supporting member provided with a through hole, an operation member having a shaft slidably inserted into the through hole, and a head provided on an outer end of the shaft, and an elastic member which is contracted to be arranged between the head and the supporting member, and further contracted in response to a movement of the operation member.

A corrector button for a watch case including a socket of axis of revolution having a threading arranged on the outer rim of a portion intended to be fitted by screwing onto a watch case, and having a cavity extending between a first end of the socket and a second end of the socket; a movable control rod engaged in the cavity of the socket and movable in translation along the axis of revolution, the movable control rod including a push-rod, having a rotation organ, and a push-button rigidly connected to the push-rod. The cavity has a portion of polygonal cross-section, and wherein the push-rod of the movable control rod includes a portion having a complementary polygonal cross-section in respect of the portion of polygonal cross-section of the cavity, such that the rotation of the push-rod via the rotation organ drives the rotation of the socket.

A multifunction correction device (100) for a case (2) of a timepiece including a horological movement (1). The correction device includes: a cylindrical body (110) integral with the timepiece case (2); a primary correction module (120) moving in translation in a first direction, having a primary control member (121) integral with a primary control stem (123), which operates a first function corrector (10) of the horological movement (1); and a secondary correction module (130) moving in translation in a second direction parallel to the first direction, the secondary correction module (130) comprising a secondary control member (131) integral with a secondary control stem (133), which operates a second function corrector (12) of the horological movement (1), the cylindrical body (110) receiving the primary correction module (120) and the secondary correction module (130).
