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.
Claims17
A watch with a rotatable, indexable bezel, comprising:
- the watch having a middle part, and the middle part having an axial end with a periphery;
- a bezel over and rotatable around the axial end of the middle part, generally around the periphery thereof;
- the bezel and the middle part being respectively so shaped as to define an annular space between them generally at the periphery of the middle part;
- an indexing system in the annular space, the indexing system comprising
- a toothed ring, which is a separate element from the bezel and from the middle part, the toothed ring having teeth facing into the annular space;
- and
- an elastic element, which is also a separate element from the bezel and the middle part and from the toothed ring, extending elastically into the teeth for restraining rotation of the bezel around the middle part periphery;
- the toothed ring and the elastic element being urged against each other by their engagement against the bezel and the middle part.
