Watchcase, one set of components constituting watchcase, and method for assembling watchcase

Abstract

Abstract PURPOSE: To provide a highly reliable impermeable watchcase by providing a first annular seat extended in the radial direction inside a glass edge, a second annular seat formed by combing the watchcase and glass edge with each other, and a packing. CONSTITUTION: A watchcase is constituted of a watchcase bandpack 2 made of a plastic material, a metallic glass edge 1, and a packing 4. The impermeable sealing means of the pack 2 and edge 1 has a first annular seat 6 which is put in the edge 1. An annular projection 13 integrally formed with the pack 2 is inserted into the seat 6 and, at the same time, has such a shape that can prevent a second annular seat 7 from being separated from the edge 1. The seat 7 is formed of the pack 2 and edge 1 and the packing 4 is put in the seat 7. Because of the packing 4, the watchcase can be constituted in an impermeable state and the the reliability of the watchcase can be improved. In addition, the cost of the watchcase can be reduced.
