A watch case (10) including a back (30) driven into a middle (20) by a joint (40), and including a body (31) from which radially extends a lip (32), the body (31) including an axial annular shoulder (310) and the lip (32) including a radial annular shoulder (320). The middle (20) has an axial opening (21), an axial annular shoulder (200), and a radial annular shoulder (201) resting against the radial annular shoulder of the lip, the joint being interposed between the axial annular shoulders. The axial annular shoulders have peripheral profiles of complementary shapes, substantially circular, including one and the other, a first circular-arc-shaped portion having a first radius (R1, R2), and a second circular-arc-shaped portion to which is connected the first portion, having a second radius (r1, r2) the value of which is lower than that of the first radius (R1, R2).

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 an alignment feature formed thereon. The alignment feature engages the upper or lower housing member and positions the wrap within the upper and lower housing members wherein axial seal members formed on the wrap are compressed and engage the device when the upper and lower housing members are coupled defining a continuous seal about the device.

Disclosed is a device case including: a case main body; a second exterior member attached so as to surround an entire periphery of an upper outer periphery of the case main body; and a first exterior member attached so as to surround at least an upper outer periphery of the second exterior member and the case main body. The second exterior member is formed of a material softer than the first exterior member and interposed between the case main body and the first exterior member along the upper outer periphery of the case main body, and has at least a part of an outer peripheral side surface covered by the first exterior member.

Provided is an electronic timepiece including a main body and an exterior that is attached to the main body and can hold a band. The exterior has a first opening on one end. The first opening has a first protruding part protruding inside the first opening on a side facing a back side of the band inserted through the first opening. The band has a first planar part on the back side and a second planar part that swells more than the first planar part on the back side. A boundary between the first planar part and the second planar part forms a step part. When the band is inserted through the first opening of the exterior, the step part and the first protruding part are engaged with each other, thereby holding the band to the exterior.

A protective wristwatch sleeve device for protecting a wristwatch or other wrist-worn device during use includes a sleeve defining an interior space, the sleeve has a pair of edges, each edge defining an associated opening to the interior space. The sleeve is elastically stretchable and is configured for stretching for wearing about a wrist and a wristwatch, thereby shielding the wristwatch from a debris. The sleeve has an inner layer adjacent to the interior space with an inner surface facing the interior space. The inner layer is elastically stretchable and soft and is configured for abutting the wristwatch when the sleeve is worn. The sleeve also includes an outer layer which is elastically stretchable and has an outer surface facing away from the inner layer.

The disclosure provides an example watch. The watch includes (a) a housing having a first face and a second face and a cavity extending therebetween, where the first face includes a first bezel coupled to a first transparent watch crystal, (b) a disc disposed within the cavity between the first face and the second face and coupled to the housing, where the disc comprises a watch face for indicating time, and (c) a case cap removably coupled to the second face of the housing, where the case cap includes a casing having a first side configured to mate with the second face of the housing and a second side configured to be engraved.

A screen protection case for an electronic device includes a shell, a protection cover, and a sealing ring. The shell is provided with an accommodating space and a window communicating with the accommodating space. The protection cover is transparent, connected to the shell, and covers the window. The sealing ring is attached to a side surface of the protection cover facing the accommodating space. The sealing ring is circumferentially continuous and hollow inside. When the screen protection case accommodates the electronic device in the accommodating space, an edge of the screen of the electronic device is abutted against the sealing ring. The screen protection case effectively reduces the production cost of the screen protection case for the electronic device. The contact area between the sealing ring and the protection cover and the contact area between the sealing ring and the screen are increased.
