A case by which impact resistance is enhanced and damages due to impacts are prevented, a timepiece equipped with the case, and a fastening member are provided. The case includes a case main body which has first insertion holes, a first exterior case which has second insertion holes coaxially corresponding to the first insertion holes and is arranged on the upper part of the case main body, and fastening members which have fixing portions to be fixed in the first insertion holes and fitting portions to be fitted into the second insertion holes. Each fitting portion is fitted into the corresponding second insertion hole while being deformed. Therefore, even if the wristwatch case is subjected to an external impact, the first exterior case does not rattle in the direction perpendicular to the axial direction of the fastening members, whereby the case main body is prevented from being damaged.

A portable object comprises a case forming a housing inside which is arranged a device that requires air to operate, and a closure device comprising at least one permeable element. The closure device is arranged to provide impermeability to liquids while allowing the atmosphere inside the housing to communicate with the external atmosphere. The case comprises a recess in which a through opening is made, said recess being closed by said closure device. The closure device comprises a permeable module mounted to move such that, in a gaseous environment, the permeable module is in a rest position allowing gases to penetrate said case opening through said permeable module, and in a liquid environment, the permeable module is in an operating position in which gases and liquids are blocked. The permeable module comprises a tubular support at the end of which is fixed a membrane.

A musical timepiece includes a gong fastened to a structure or a resonator of a watch case, the resonator rigidly assembled to the structure around a chamber, by lugs allowing vibration of the resonator within a determined frequency range, the chamber enclosing a sealing element forming with the lugs the only mechanical connection between the structure and the resonator. The structure or the resonator includes a groove receiving a gasket in contact with the structure and the resonator The structure structure or the resonator or the sealing element includes a rigid protruding relief portion compressing a gasket in its groove, with a hardness less than 20 Shore A, for minimum damping of the vibration of the resonator.

In various implementations, a cover for a smartwatch is provided that includes a housing and a flexible member (e.g., a gasket). The cover may increase user satisfaction with the smartwatch by increasing the aesthetics of the watch for the user, providing flexibility in appearance, and/or inhibiting damage to the watch itself. The gasket may secure the smartwatch in the cover, inhibit damage to the outer housing of the cover by an inner surface of the cover, and/or inhibit interference from the cover with operations of the smartwatch.

An external fitting device includes an external fitting member having a front wall member configured to cover partially a front side of a case of a wristwatch, a side wall member continuously connected to the front wall member and configured to cover a lateral surface of the case, and a locking target member provided on the side wall member, and a fixing member comprising a locking member being locked on the locking target member, and configured to fix the external fitting member to the case by the locking member.

The striking or musical watch includes a watch case having a case middle and a back attached to the case middle in a sealed manner and in a detachable manner, a glass closing the case in a sealed manner, a watch movement or a watch electronic module retained in the interior of the watch case and equipped with a sonic vibration generator to be activated during specific periods in order to produce a sound or music. The watch includes at least one acoustic radiation membrane made at least in part of wood or a wood composite material and attached to a part of the case in order to radiate the sound produced by the sonic vibration generator towards the exterior of the case.

A stretchable watch band can include braided strands that provide a comfortable fit around the wrist of the user. The watch band can stretch and conform to the user based on the elasticity within each strand and based on the ability of the strands to move relative to each other. End sections of the watch band can include attachment elements that securely connect the watch band to a housing of the watch. The end sections can be configured to releasable connect to the housing in a manner that is reliable and easy for a user. Additionally, the watch band can provide a smooth transition from the size and/or shape of the housing to a size and/or shape of a continuous section of the watch band. Additionally, the watch band can conceal portions thereof other than the braided strands when connected to the housing of the watch.

The present invention belongs to the technical field of protection shells, specifically discloses a smart watch protection shell, comprising a frame and a protection case, wherein a protection film is covered at a display window of the frame, the protection case is sleeved and attached outside the frame, the protection film, the frame and the protection case are enclosed to form a dial cavity, and two opposing side walls of the dial cavity are provided with relief holes, respectively. According to the smart watch protection shell disclosed in the present invention, not only the sides and the display screen of the dial can be protected, but also the dial is not easy to fall off and prevented from being crushed, which is convenient for users.

Disclosed is a timepiece including a case containing a movement, at least one device for generating vibrations intended to produce at least one sound, at least one device for amplifying the vibrations generated by the vibration-generating device, the device for amplifying the vibrations including a lever linked to a support by an articulation about a single axis of rotation and arranged to be actuated by a transmission member cooperating with the vibration-generating device to transmit the vibrations to the lever. The device for amplifying the vibrations includes at least one plate arranged to cooperate with the lever in order to be displaced according to a vibration movement, the plate being housed in the case so as to form a free space on the periphery of the plate over at least 70%, preferably at least 80%, of the perimeter of the plate.

A striking or musical watch with an acoustic waveguide arrangement. The striking or musical watch (1) includes an at least partially flexible waveguide (2) secured to a fixed part (8) inside the watch to guide the acoustic waves generated by a first portion (2′) of the at least partially flexible waveguide towards a radiating element. The radiating element can include a watch crystal (3) connected to a bezel (5) and a membrane (4) for connecting the bezel to a middle part (6) of a watch case. The flexible waveguide is configured to change the direction of acoustic vibration from the first portion to the radiating element.
