A Dewar casing (1) for mechanical and/or functional components (5) of a watch (10), provided with an enclosure (4) wherein a case (12) of the watch (10) can be removably arranged, a display interface of which is disposed facing a crystal (6) of the casing (1), the casing (1) including a reversible fixing device (13) fixing the watch (10) case (12) in the enclosure (4) while keeping it away from functional elements (15) forming the enclosure (4) of this case (2), the crystal (6) of the casing (1) including an element for varying the transmittance (7a) of the crystal (6) and an element for generating illumination (7b) directed towards a display interface of the watch (10).

A case including a case main body, an operation member having an operation head portion which protrudes outside of the case main body, an exterior member which is detachably attached to the case main body while covering outer periphery of the case main body, in which the case main body has a protection projection provided on an outer peripheral surface such that an outward projection length becomes shorter from an upper side toward a lower side, and the exterior member has a housing portion which houses the protection projection.

An assembly for a consumer product, such as a wristwatch or other wearable electronic device, can securely retain a cover member against a housing of the product. A retaining member from within the housing can engage and secure the cover member to provide a fluid barrier. The cover member can include a window or other components of a sensor device. The parts can be easily disassembled without causing permanent damage.

An exterior member including an exterior main body which covers a whole periphery of a portion of an outer surface of a case main body in a peripheral direction; and fixing projection sections which are formed on predetermined lower edge portions of the exterior main body while projecting toward outer peripheral sides and fix the exterior main body to the case main body by a fixing member attached covering an outer peripheral surface of the case main body.

An assembly for a consumer product, such as a wristwatch or other wearable electronic device, can securely retain a cover member against a housing of the product. A retaining member from within the housing can engage and secure the cover member to provide a fluid barrier. The cover member can include a window or other components of a sensor device. The parts can be easily disassembled without causing permanent damage.

Exterior sub-assembly for a timepiece or watch or piece of jewelry, comprising a first component and a second component, arranged for a bayonet fitting between two rims and two wings comprised in the first component and the second component, and able to occupy an assembled and indexed position of the first and second components, this sub-assembly including a third component in the form of a ring, inserted between the first and second components and comprising a ring-like element housed inside a groove of the first or second component, this third component including a rotational stop with respect to the first or second component, and a resilient area with radial relief, cooperating in an angular indexing arrangement with a lug of the first or second component which is free to rotate with respect to the third component.

A watch comprises a wristwatch casing having a front surface with pivot; a mechanism enclosed within the casing including a magnetic hand positioned to rotate in the casing proximal to the front surface; a face including at least one marker for visually indicating the time and a magnetic element; and a bezel disposed above the face and extending towards the front surface to cover the side walls of the face and part of the side walls of the casing, in which the face is supported by the upper surface of the casing, being rotationally mounted to the pivot and retained by the bezel, the front surface is between the magnetic hand of the mechanism and the face, and the magnetic hand of the mechanism guides the face via the magnetic element of the face.

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 waterproof case for an electronic device that includes an upper housing member and a lower housing member including lugs formed thereon attaching to a strap member. A sealing wrap is positioned about an electronic device. The sealing wrap is positioned between the upper and lower housing members when the upper and lower housing members are coupled. The sealing wrap includes a lower wall having a thin walled section having transparent portions allowing the transmission of light.

A protective case includes: a cover part provided with an operation unit for operating a button when some member on one side thereof is moved toward the button located on the other side thereof, and configured to be detachably coupled to a product; and a locking part configured to be coupled to the operation unit to slide between the button and the member in the forward and backward directions, and also configured to be selectively spaced apart from the member and disposed adjacent to the member according to the movement to allow or block an operation of the button by the member. The protective case selectively and rapidly activates and inactivates a pressing member used to operate a button through a locking part that is reciprocally slid with a stop protrusion interposed therebetween and thus stably maintains the position thereof.
