Abstract (en)
[origin: WO2020011512A1] The invention relates to a watch, the watch case of which comprises a middle (2) and a rotating bezel (3), provided with a bezel locking system. The system comprises a rotary crown (6) which is rigidly attached to a shaft (9), the latter being arranged in a radial hole (7) in the middle. By rotating the crown (6), the user can screw or unscrew the shaft with respect to the hole. The shaft comprises a frustoconical section (12) which interacts with a pin (21) mounted perpendicularly to the shaft, and biased towards the shaft by a spring (22). By screwing the shaft (9) into the hole (7), the frustoconical section pushes the pin into a receiving space (15) provided on the inner surface of the bezel (3), which locks the bezel. The unscrewing of the shaft (9) automatically disengages the pin (21) outside of the receiving space, by virtue of a return force exerted by the spring (22). According to a preferred embodiment, the crown incorporates a helium valve mechanism.
