ABSTRACT:
A waterproof watch case construction depends on gaskets alone for waterproofing and is free of cement. The construction is such that a broken crystal can be readily replaced, and the watch case itself can be of any shape, including square, ovoid and hexagonal, as well as circular. The watch crystal is located positively by means of a bezel and a ring which compress a gasket both axially and radially against the watch crystal.
