ABSTRACT:
The watch bezel is mounted on the middle part of the case by means of a wave-shaped inclined spring wire. Between the middle part of the case and the bezel is located a flat spring having inclined tongues forming pawls engaging into the toothing of a toothed ring. This ring is freely located between the middle part of the case and the bezel, and its angular position relatively to the bezel is determined by pins engaging into holes of the bezel. The indexing system of the bezel composed of the toothed ring and of the flat spring with its pawls is thus freely disposed between the bezel and the middle part of the case, and all constituents are maintained in place only by spring force of springs. The elements of the system and its assemblage are particularly simple and inexpensive.
