ABSTRACT:
A case body is fixed to a glass by means of an interposed ring of a vulcanizable elastomer, this ring being bonded by vulcanization either directly to the glass or to a metallized coating applied to the glass, as well as to the upper surface of the case body. The metallic coating is applied to an annular zone at the periphery of the underside of the glass. Instead of this coating, the inside surface of the glass may be frosted in that zone.
