Abstract

The case is essentially made up of a hollow middle cum glass unit (1), consisting of an integral glass pressing, and of a metal back (10) closing off a cavity (5) defined by the inside surface of the hollow unit, the cavity providing a housing for a movement. In the cavity is mounted a metal ring (15) having a centering flange (16) bearing against the middle portion of the unit. In the space between the ring and the middle portion are inserted a deformable rubber gasket (19) and a metal annulus (18) whose radially outer surface is formed with a bevel (18') in the region nearest the gasket. Screws (20) secure the back (10) to the ring (15) and press it against the annulus (18). On being driven home, the screws wedge the bevel (18') between the gasket and the ring thereby to apply a radial force on the gasket . This force presses the gasket against the middle portion of the unit and prevents it from moving out of the cavity.
