Abstract
A timepiece has a case band having a front side end part that projects inwardly toward the hollow interior of the case band and terminates in a front opening. A case back is detachably attached to a back side end part of the case band. A glass is fixed to an annular edge member that seats on a front face of the front side end part. The edge member has a tubular part slidably inserted into the front opening and threadedly engaged with an annular attaching member in the interior of the case whereby the front side end part of the case band is sandwiched and held between the edge member and attaching member. By detaching the case back and using a tool to unthread the attaching member from the edge member, the edge member and glass can be removed as a unit from the case band for repair or replacement.
