Abstract: A watchcase comprises a case body, a bezel, and a support member affixed to the bezel for removably connecting the bezel to the case body so as to permit easy removal and replacement of the bezel. The support member has at diametrically opposite locations thereof outwardly extending flange portions, and corresponding recesses are provided in the case body at diametrically opposite locations for movably receiving therein respective ones of the flange portions with sufficient clearance therebetween to enable a sufficient extent of movement of the support member relative to the case body in the diametrical direction of the flange portions to permit removal and replacement of the bezel without deformation of either the case body or bezel. A deformable elastic member is interposed between the bezel, support member and case body and the elastic member is configured so as to undergo elastic deformation during removal and replacement of the bezel thereby preventing deformation of both the case body and bezel.

Abstract: A watchcase comprises a case body, a back cover connected to the back of the case body and a bezel connected to the top of the case body. A support member is connected to either the back cover or the bezel and comprises an outwardly extending flange, and oppositely disposed beads extending outwardly from the flange. The beads are configured to coact with recesses which are oppositely disposed in the inner surface of the case body so as to be received therein upon insertion of first one bead in its respective recess followed by the displacement of the support member relative to the case body so as to temporarily dispose the beads in extreme positions with respect to the recesses, and the beads are maintained in their respective recesses upon the return displacement of the support member so as to move the beads from their extreme positions. The beads are normally biased out of their extreme positions when inserted in the recesses.
