Abstract
Abstract A watertight watch case of the two piece type wherein the caseband and back are formed as a single unit with a separate bezel. The bezel includes a glass snap integrally formed therewith and is assembled to the caseband and back unit with a interposed packing that is subjected to radial compression between the bezel acting on one surface, and the glass and caseband and back unit acting on the opposite surface. The arrangement assures resistance to water and at the same time maintains the assembly of the watch case.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A watertight watch case of the two-piece type in which the caseband and back are formed as a single unit with a separate bezel and wherein the bezel includes a glass snap integrally formed therewith and is assembled to the caseband and back unit by means of an interposed packing subjected to radial compression between the bezel acting on one surface thereof and the glass, and a caseband and back unit acting on an opposite surface thereby to assure water resistance while maintaining the assembly of the watch case, said caseband including a plurality of symmetrically disposed holes extending from the back of the caseband proximate the perphery thereof through to a matching surface of the bezel whereby introduction of a matching tool facilitates disassembly of the watch case.
Claim 2
Dependent Claim
129 words
