The present disclosure discloses a watch with a case convenient to replace. The watch includes a case, a movement and an inner container, wherein the movement is disposed on the inner container. The watch further includes an engagement structure for assembling the case and the inner container; when the case is dismounted, the engagement structure is pressed to be elastically compressed towards one side of the inner container so as to be disengaged from the case; and when the case is mounted, an outer side of the inner container is sleeved by the case, and the case is pressed along a side wall of the engagement structure, so that the engagement structure is engaged with the case. The watch is convenient to operate, so that a user can select the proper case and inner container to be matched and combined, and waste caused by purchasing various different watches is avoided.

A hold-down member including a plate member which is arranged on a first member having an electronic component and supports the first member, and a resin sheet which is adhered to the plate member, pressed by a second member that is arranged to be rotatable with respect to the first member, and slides on the second member.

A sub-assembly of external parts including, coaxially with a first component and a second component compressing together a sealing and friction joint, and interposed therebetween, a bolt securing them together by axially blocking the first component, and a lower surface of which lies, in the assembled position, in the vicinity of an upper surface of the second component, which bolt includes a lower relief protruding axially from this lower surface towards the second component, arranged to either complementarily cooperate with an oblong groove which is partially of revolution that the upper surface includes, and interrupted by a stopper limiting the angular travel between the second component and the bolt within a turn, or else to constitute an angular stopper to an upper relief protruding from the upper surface of the second component and extending axially towards the bolt.

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).

The invention relates to a timepiece comprising a watch case formed by a middle closed by a back and a crystal, the middle being equipped with horns defining a space for receiving a bracelet strand, said timepiece comprising a sole arranged to rest against the back, the sole, the bracelet strand and the space between the horns comprising shaped elements arranged to cooperate by interlocking when the middle, the sole and the strand are assembled.

A cover (100) for a wrist-worn electronic device, which cover (100) includes an exterior layer (101) which forms an exterior of the cover (100), and an interior layer (114) which forms an interior of the cover (100). The interior layer (114) abuts against an exterior of the electronic device when the cover (100) is arranged on the wrist-worn electronic device. The interior layer (114) is attached to the exterior layer (101), and includes a raised bezel (112) which extends further from a face of the wrist-worn electronic device than the exterior layer (101) so as to form at least a part of an exterior surface of the cover (100).

In various implementations, a cover for a smartwatch is provided that includes a housing and a flexible member (e.g., a gasket). The cover may increase user satisfaction with the smartwatch by increasing the aesthetics of the watch for the user, providing flexibility in appearance, and/or inhibiting damage to the watch itself. The gasket may secure the smartwatch in the cover, inhibit damage to the outer housing of the cover by an inner surface of the cover, and/or inhibit interference from the cover with operations of the smartwatch.

An external fitting device includes an external fitting member having a front wall member configured to cover partially a front side of a case of a wristwatch, a side wall member continuously connected to the front wall member and configured to cover a lateral surface of the case, and a locking target member provided on the side wall member, and a fixing member comprising a locking member being locked on the locking target member, and configured to fix the external fitting member to the case by the locking member.

The present invention belongs to the technical field of protection shells, specifically discloses a smart watch protection shell, comprising a frame and a protection case, wherein a protection film is covered at a display window of the frame, the protection case is sleeved and attached outside the frame, the protection film, the frame and the protection case are enclosed to form a dial cavity, and two opposing side walls of the dial cavity are provided with relief holes, respectively. According to the smart watch protection shell disclosed in the present invention, not only the sides and the display screen of the dial can be protected, but also the dial is not easy to fall off and prevented from being crushed, which is convenient for users.

A timepiece includes a watch case formed by a middle closed by a back and a crystal, the middle being equipped with horns defining a space for receiving a bracelet strand, the timepiece including a sole arranged to rest against the back, the sole, the bracelet strand and the space between the horns having shaped elements arranged to cooperate by interlocking when the middle, the sole and the strand are assembled.
