A wristwatch comprises an annular case band, a case back, an annular edge member, a glass, and an attaching member. A fitting hole is formed in a front side end part of the case band, and an edge receiving face is provided around the fitting hole. The case back is detachably attached to a back side end part of the case band. The glass is fitted and fixed to an annular step part having been formed in the edge member. In the edge member there are provided a tubular part fitted to the fitting hole so as to be capable of being inserted and disengaged, and a cover part overlapping with the edge receiving face. The tubular part is detachably attached to the front side end part by the attaching member attached/detached under a state that the case back has been detached.

Claims

1. A timepiece comprising: an annular case band which has a front side end part forming a fitting hole, and in which this end part has an edge receiving face around the fitting hole;a case back having been detachably attached to a back side end part of the case band;an annular edge member which has a tubular part fitted so as to be capable of being inserted into and disengaged from the fitting hole and a cover part overlapped with the edge receiving face;a glass having been fitted and fixed to an annular step part having been formed in the edge member; andan attaching member which detachably attaches the tubular part to the front side end part, and which is attached/detached under a state that the case back has been detached.

2. A timepiece according to claim 1, wherein there has been possessed an annular seal packing having been nipped between the edge receiving face and the cover part under a compressed state.

3.
