ABSTRACT:
To provide a timepiece in which it is possible to promote an edge thinning of an edge member without impairing an exchangeability of a gasket between the edge member to which a glass has been fixed and a case band, and a selectivity of a fixation means of the glass to the edge member. In a case band of an armor case in which a timepiece movement with a dial has been built in, there is provided an inner periphery convex part forming a fit hole while protruding to a case band inside. In an annular edge member which is overlapped to a front side of the case band and to which a glass has been fixed, there are provided a tubular fit part fitted to a fit hole, and a dial cover site covering a peripheral part surface of the dial. An annular seal gasket made of an elastic material is nipped, in an outside than the fit hole, between the edge member and the case band. Plural threaded holes are formed over the inner periphery convex part and the fit part, and there is made such that one part of each of the respective threaded holes is included in a projected region of the seal gasket to a back side. The edge member is retained to the case band by detachably screwing a threaded-axle-like connection member to each of the respective threaded holes from back sides of the inner periphery convex part and the fit part.
