A case including a device case, and an exterior member which is attached covering an outer circumferential surface of an upper part of the device case, in which the device case has a catching portion formed in an outer circumferential portion thereof, the exterior member has an engaging portion which is formed on an inner side portion thereof, engages with the catching portion when the exterior member is attached to the device case, and prevents the exterior member from being detached from the device case, and a support area which supports the engaging portion of the exterior member is formed of a material whose hardness is lower than hardness of a material of an area adjacent to the support area.

A device case includes a resin case body having an opening which is disposed on a viewing face of the case body and a step which is disposed on an interior of the opening and protruding further to the interior than an inner face of the opening. The device case further includes a windproof member having an outer diameter smaller than an inner diameter of the opening of the case body and larger than an inner diameter of the step; and an adhesive section bonding and fixing the windproof member at a position to seal the opening of the case body. The adhesive section has higher flexibility than the case body.

A portable object includes a case forming a housing inside which is arranged a device that requires air to operate, and a closure device including 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, the recess being closed by the closure device. The closure device includes a permeable module mounted to move such that, in a gaseous environment, the permeable module is in a rest position allowing gases to penetrate the case opening through the 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.

An attachment link for a watch band is arranged to attach the band to a watch case between the horns. A first end of the attachment link is fixed to a watch band strand and the second end of the attachment link is fixed to the case with a bar. The link is between the horns and against the case. The attachment link includes a device for blocking pivoting in order to firmly hold the attachment link between the horns.

A smart wristband with a rotatable dial has a dial, a case and a band. The case is embedded in the band. The dial is rotatably disposed in the case. An end of the dial is provided with a USB port, and the USB port is hidden between the dial and the case. The dial has a bottom case, a rotating ring is fixed at a bottom of the bottom case, the case is sandwiched between the bottom case and the rotating ring, and relative rotation between the dial and the case is achieved by the cooperation and relative rotation between the rotating ring and the case. An opening is provided at an end of the bottom case, a protruding buckling rib is provided at the other end, and a buckling groove that matches the protruding buckling rib is formed at the corresponding position of the case.

An acoustic device includes a waterproof vibrating membrane and a magnetic component disposed below the waterproof vibrating membrane. The waterproof vibrating membrane includes a convex portion which protrudes toward a position of the magnetic component, or a concave portion which is recessed opposing to a position of the magnetic component. The magnetic component includes a concave pressure buffering portion corresponding to a shape of the convex portion of the waterproof vibrating membrane wherein the concave pressure buffering portion is recessed toward a side opposing to a side on which the waterproof vibrating membrane is located, or a convex pressure buffering portion corresponding to a shape of the concave portion of the waterproof vibrating membrane wherein the convex pressure buffering portion protrudes toward a side on which the waterproof vibrating membrane is located.

A cover is releasably secured over an opening by an apparatus or a fastener system and may be used in a book-clock system having a clock movement housed within a space hollowed through the book's pages. A clock shaft protruding from the movement passes through an opening in a fastening element and then through a hole in the book's front cover. The clock shaft supports and moves the clock hands on the front. The fastening element may be a flexible strip. It may be positioned in a U-shape about the clock movement so at least a ferromagnetic part of the fastening element is adjacent to portion of the clock movement facing the back cover. A magnet is positioned on the back cover so when closed, the magnet meets the ferromagnetic part of the fastening element. A magnetic force is exerted and releasably holds the back cover of the book closed.

An isothermal device (1) for mechanical and/or functional components (5) of a watch (10), including a case (2) provided with an enclosure (4) wherein a case (12) of the watch (10) can be removably arranged, a crystal (11) arranged facing a crystal (6) of the case (2), the device (1) comprising: a reversible fastening device (13) fastening the watch (10) case (12) in the enclosure (4) by keeping it away from functional elements (15) of the case (2), the elements (15) forming the enclosure (4) comprising a middle (9a), a back (9b) and the variable-opacity crystal (6) of the case (2), and a system (3) for dynamically controlling the temperature of the enclosure (4) comprising the variable-opacity crystal (6) and a control unit (8) configured to control the opacity of the crystal (6) of the case (2).

A molded part includes a resin plate molded from resin material, and the resin plate has a sheet area of sheet-like shape and multiple assembly component parts for assemblage to a module component part, the sheet area and the multiple assembly component parts being integrated into a single unit, and the multiple assembly component parts are configured to be individually separable from the sheet area.
