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. The elastic member has sufficient elasticity to urge the support member flange portions extend into the case body recesses upon replacement of the bezel thereby removably joining the bezel to the case body in a fluidtight manner.
