A timepiece has an annular case band having a front side end part that protrudes radially inwardly toward the inside of a case band and defines a front opening of the case band. A case back is detachably attached to a back side end part of the case band. An annular edge member seats on a front surface of the front side end part and has a tubular part removably inserted into the front opening of the case and, the tubular part having an annular attaching groove that opens to an outer periphery of the tubular part, and a glass is fixed to the edge member. An elastically deformable open-ended snap ring is detachably attached to the attaching groove in an elastically deformed state, and the snap ring abuts a back surface of the front side end part of the case band so that the front side end part is held between the edge member and the snap ring. The snap ring is detachable from the attaching groove when elastically expanded by a tool inserted from the back side of the case band to enable removal of the edge member and glass as a unit from the case band for repair or replacement.
