Disclosed herein is an encasement for a watch.

A Dewar device (1) for mechanical and/or functional components (2) of a watch (3), the device (1) being provided with a bracelet and a casing (4) including an enclosure (5) in which a case (6) of the watch (3) is capable of being arranged and at least one fastening device (7) fastening the case (6) of the watch (3) inside the enclosure (5) of the casing (4) while keeping it away from the set of elements (10a, 10b, 10c) of the casing (4) defining this enclosure (5), the set (10a, 10b, 10c) including at least one transparent external element (10a) made of a transparent ceramic material, in particular a transparent polycrystalline ceramic material.

The present invention relates to a watch protective case with a knob, including a soli rubber case body covering the outside of a watch in a cooperative manner and a hard rubber cover connected to the soft rubber case body in a cooperative manner on an upper end of the watch. A first soft rubber watchband and a second soft rubber watchband are respectively provided at two ends of the soft rubber case body, an adjustment hole is opened in a position on the soft rubber case body that corresponds to a watch button, and a knob adjustment component connected to the watch button in a cooperative and adhesive manner is provided within the adjustment hole. In addition, the adjustment hole is blocked by the knob adjustment component, which can effectively provide dust-proof and aesthetic effects.

A back (1) for a watch case (50), the back (1) including a first element (10) arranged so as to be screwed onto the watch case (50), and a second element (20) including an end face bearing a pattern (M), the second element (20) being mounted such that it can move in rotation about an axis (C) passing through the centre of the case (50), wherein the second element (20) has a brake arranged so as to hold same relative to the first element (10) in different angular positions about the rotational axis (C), the brake being disposed between the first and second elements (10, 20).

A Dewar device for mechanical and/or functional components of a watch, this device including a wristlet; a housing 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 housing defining this chamber; at least one fastening device fastening this watch case in this chamber of the housing while maintaining it distant from this set of elements, and a device for actuating at least one control element of this watch by the movement in translation of an external parts element of the housing in the direction of a back of this housing.

A case middle/horn connection device for a watch, a method for attaching an attachment piece including at least one horn to a case middle and a case middle/horn assembly. The connection device includes an attachment piece including at least one horn having a first connector and a case middle having a second connector, the first connector being configured to cooperate with the second connector to attach the attachment piece to the case middle. The first connector includes a tongue with a recess. The second connector includes a groove with an undercut portion. The undercut portion is configured to lodge inside the recess of the tongue; and the case middle and the attachment are made integral when the undercut portion of the second connector is lodged in the recess of the tongue of the first connector.

A watch includes a case, and a solar cell disposed inside the case and including a substrate made of resin and having a surface, a power generating unit having, at the surface, a first electrode, a first semiconductor layer, and a second electrode that are stacked in order, a first antenna including a third electrode that is provided at the surface and that is disposed at a position not to overlap the power generating unit in a plan view viewed in a direction orthogonal to the surface, and a protective layer disposed covering the power generating unit and the first antenna.

An exterior member including a first fiber resin body formed by a plurality of first fiber resin sheets being laminated, and a second fiber resin body formed by a plurality of second fiber resin sheets being laminated, in which the first fiber resin sheets of the first fiber resin body are laminated while being inclined with respect to the second fiber resin sheets of the second fiber resin body.

A switch device including a base member provided with a stem insertion hole, an operation member which has an engaging groove provided in an outer circumferential surface thereof, and is slidably and rotatably inserted into the stem insertion hole of the base member, a stopper member having an engaging portion which is arranged in the engaging groove of the operation member and moved along with sliding of the operation member, and a release member which releases the engaging portion from the engaging groove, in which the release member includes a pressing portion which is operated from one surface side of the base member so as to release the engaging portion from the engaging groove.

A watch can include a watch band having a first strap segment, a second strap segment, a nest portion secured between the first strap segment and the second strap segment, and an opening extending through the nest portion. The watch can further include a housing releasably mountable to the nest portion, and a sensor disposed within the housing and configured to align with the opening when the housing is mounted to the nest portion.
