A watch including a gasket (18) arranged at the periphery of the glass (14), an intermediate portion (20) laterally surrounding the analogue display and defining a radial surface forming an axial stop for the glass, a solar cell (30) extending at least mostly between the lower level of the dial and the glass and being arranged behind the intermediate portion, which is formed at least partially by a translucent or transparent material and configured to make it possible for the incident light to propagate in the intermediate portion and to subsequently reach the solar cell. The gasket is also formed at least mostly by a translucent or transparent material and it forms with the intermediate portion axially a continuous medium. In variants, the gasket is arranged axially adjacent to the intermediate portion or it is axially separated from the intermediate portion by a translucent or transparent intermediate medium.

Wearable electronic devices, such as watches, can provide a seal member to form a fluid barrier between an inner chamber therein and outer chambers, as well as an external environment. Components within the sealed inner chamber can be protected from elements from the external environment (e.g., water ingress, etc.). The components outside of the inner chamber can include sensor modules and the like. Such components can be operatively connected to components within the inner chamber, for example, by a flex circuit that extends across the seal member. The component can interact with a watchband when coupled to a watch housing of the watch.

A closing/opening system for a case of a timepiece is defined particularly in first and second parts of the case. The system includes a device for producing a mechanical connection, particularly a bayonet connection between these first and second parts and a device for creating a friction torque between these first and second parts. The device for creating a friction torque includes tightening faces to cooperate with one another when closing/opening the case and which are defined in the first and second parts. The system further includes a tightening element in one of these two tightening faces. The tightening element generates a constant friction torque during a course of travel of one of the two parts relative to the other when closing/opening the case of the timepiece.

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 case includes a main case body and an exterior member. The exterior member is welded to the main case body with laser light. The laser light is irradiated onto a welding part of the main case body and the exterior member and reflected at an irradiation surface, and a reflected-light receiving part is formed at a position where the reflected laser light is irradiated according to an incidence angle of the laser light to the irradiation surface. The exterior member includes a flange part which is disposed on an upper side of the main case body and which protrudes toward an inner side of the main case body. A lower surface of the flange part includes a module receiving surface which receives a module to be disposed inside the main case body, and the reflected-light receiving part is formed at a part of the module receiving surface.

A water-resistant watch case of a diving watch, includes a back mounted on a lower side of a middle part, and a crystal mounted on an upper side of the middle part. The crystal includes an annular peripheral surface mounted by a first portion of an annular gasket made of amorphous metal on an inner annular surface that is complementary in shape, on the upper side of the middle part. A second portion of the gasket on the first portion of the gasket maintains the crystal against the middle part. The annular peripheral surface of the crystal is inclined towards the inside of the watch case at an angle less than 90° relative to a central axis perpendicular to the plane of the watch case to distribute stresses between the crystal and the middle part due to the water pressure.
