The present disclosure includes a case body configured to accommodate a movement, and a rotating bezel attached to the case body. The rotating bezel includes a bezel body having an annular shape, and a display plate detachably attached to the bezel body. An engagement protrusion protruding toward the bezel body and being continuous in a circumferential direction is provided at the display plate. A plastic gasket having an annular shape is disposed between the bezel body and the engagement protrusion. A first recessed portion is provided in an outer circumference of the display plate. A second recessed portion is provided in the engagement protrusion of the display plate so as to correspond to a position of the first recessed portion.

A timepiece includes a locking device capable of blocking the translation of a valve or of a control member in the position the closest to the central axis of the case. The locking device includes a blocking element capable of undergoing translational displacement along a radial axis between a locking position and an unlocking position, where the member is respectively blocked or free to move in translation, a part mounted such that it can move in rotation about the central axis of the case and intended to be set in rotation by a user, drive device linking the angular displacement of the part mounted such that it can move in rotation to the translational displacement of the blocking element between the locking and unlocking positions.

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 an irradiation surface. A welding part of the main case body and the exterior member is formed on the inner periphery surface extending along a height direction of the case and is formed such that the irradiation surface is perpendicular to the incident laser light.

A case including a case member having a back cover attached thereto, and a cover member which is arranged on a side of the back cover opposite to the case member side while covering an outer circumferential surface of the case member and on which band attachment sections are provided corresponding to the outer circumferential surface of the case member.

A housing includes: a housing body, having a cavity therein, with a first through hole in an outer wall thereof. The first through hole is in communication with the cavity, a first separate plate and a second separate plate are provided in the cavity, a gap between the first separate plate and an inner wall at one side of the cavity is in communication with the first through hole. A first recess for placing a water absorption device is provided between the first separate plate and the second separate plate, a bottom of a second recess between the second separate plate and the inner wall at another side of the cavity is in communication with the first through hole. A partial bottom of second recess close to first through hole is at a lower position than another partial bottom of second recess away from first through hole.
