A watch case includes a capsule receiving a watch mechanism, arranged along a main axis, and which includes a front side that has the watch face. The watch case further includes a middle surrounding the capsule and provided with an essentially cylindrical housing open toward the back from which side it receives the capsule. The watch case further includes a bezel placed against the back of the capsule. The bezel includes tabs arranged on the outer contour of the capsule, which are in a blocking position partly inserted in the interior of at least one groove having a circular orientation, produced in the cylindrical part of the housing of the middle.

A musical watch case including a case middle with surfaces for receiving and supporting a cover with a bezel, and a casing ring, and supporting at least one gong with a resonant part distinct from the walls of the case middle, which supports the cover via distinct and remote lugs included in the bezel or the case middle and which are arranged to allow vibration of the cover, and form, with at least one gasket, the only direct contacts between the bezel and the case middle, which includes, around an annular wall defining an inner chamber around the casing ring, and around all the other these lugs, a resonator ring integral with the case middle distant at every point from the bezel and from the lugs, forming with this wall an external radiating cavity.

A timepiece, in particular a pocket watch, that includes a case delimited by a middle, the timepiece further including at least one cover covering a device for displaying information, as well as a device for controlling the opening of the at least one cover, this control device including a ring pendant and a command transmission member, the ring pendant arranged such that it is pushed in a rectilinear manner a first time towards the middle into a first abutment position, then such that it is rotated in a first direction into a second abutment position, then such that it is pushed in a rectilinear manner a second time towards the middle so as to cause the cover to open by an action on the command transmission member.

A wearable device and a method for performing one or more actions using a wearable device are disclosed. The wearable device includes a bezel ring, a watch dial a flexible ring, and a plurality of springs. The bezel ring includes a plurality of holes along a circumference of the bezel ring for placement of a plurality of magnets. The watch dial includes an outer periphery with another plurality of holes at a uniform distance. The watch dial also includes an inner periphery to house inertial sensors at a predetermined position. The flexible ring placed in between an inner surface of the bezel ring and the watch dial. A plurality of springs are placed within the other plurality of holes of the outer periphery of the watch dial. The bezel ring is configured to support at least one of tilting, shifting and rotation over the watch dial.

A rotating-bezel system intended to be mounted for rotation on a watch-case middle inside which a horological movement is housed, including a ceramic rotating bezel, an annular ring intended to cooperate with an element angularly secured to the middle, and an annular joint for connection between the rotating bezel and the annular ring, the annular ring being placed in the rotating bezel. According to the invention, the system further includes at least one element for locking the annular ring on the rotating bezel, and at least one element being configured to lock any relative rotation between the annular ring and the bezel and to thus angularly secure the assembly formed by the ring and the bezel.

The present disclosure provides a protection casing assembly for a wearable device. The protection casing assembly includes a main case and a frame. The main case has a first accommodation space and configured to allow a wearable device to be disposed detachably. When the wearable device is disposed in the first accommodation space, the wearable device and the main case define a second accommodation space adjacent to at a device surface of the wearable device. The frame is detachably disposed in the second accommodation space.

A musical watch case including a case middle with surfaces receiving and supporting a cover with a bezel, or a case back, and a casing ring, the case including at least one gong fixed to the case middle with a resonant part distinct from the walls of the case middle, which supports the cover via lugs included in the bezel or the case middle and which are arranged to allow vibration of the cover assembly at frequencies from 4 kHz to 6 kHz, these distinct and distant lugs forming, with at least one gasket, the only direct contacts between the bezel and the case middle, between which each lug includes a thin, elastic, median strip, more flexible than its solid distal end, and of smaller thickness than the smallest cross-section of these gongs.

A timepiece including a device for opening a cover including a fixed pendant mounted inside a middle part and a movable pendant for sliding within the fixed pendant towards the center of the case, the movable pendant having a guide element for moving along an axial guide groove, then in a circumferential guide groove into which the axial guide groove opens out and which is delimited by a boundary, such that, when the movable pendant is pushed, this movable pendant can be firstly displaced axially, then pivoted by an angle defined by the place at which the guide element abuts against the boundary, the movable pendant having a helical groove which comes into contact with at least one pin arranged with a clearance between the movable pendant and the locking spring and which is axially displaced towards the locking spring when the movable pendant is pushed, then pivoted, such that the pin presses against the locking spring and releases the cover.

An exterior member that is favorably manufactured, a case having the exterior member and a timepiece having the case are provided. The exterior member includes an exterior main body section in which a first resin layer is provided on one side of a sheet member formed of carbon fiber and a cutout recess section from which a portion of the sheet member is exposed is provided in the first resin layer on the one side of the sheet member, and a protection member which covers the cutout recess section of the first resin layer. Accordingly, the exterior member is favorably manufactured with its strength being increased.

A method for structuring a decorative or technical pattern in the thickness of an object made of an at least partially transparent amorphous, semi-crystalline or crystalline material, wherein the object is made of an at least partially transparent material including a top surface and a bottom surface which extends away from the top surface. The top or bottom surfaces is provided with a mask defining an opening whose outline corresponds to the profile of the pattern to be structured, the mask covering the top or bottom surface at the positions which are not to be structured. The pattern is structured with a mono- or multicharged ion beam through the opening of the mask, wherein the mechanical properties of the mask are sufficient to prevent the ions of the ion beam from etching the top or bottom surface at the positions where this top or bottom surface is covered by the mask.
