Abstract
A device for locking the rotatable bezel of a watch and for rendering the winding button thereof watertight comprises a plastic washer connected to a flat surface of said button, coaxially thereto, so as to engage with circumferential knurling of the rotatable bezel, when the button is in a returned position, adjacent to the casing of the watch, in order to ensure the locking of the bezel. The device further comprises a seal which is carried by the button so as to be compressed between it and the casing when the button is in said returned position, in order to ensure watertightness of the button. Pressure means, movably supported by the casing, in a first position axially press the button holding it in said returned position and, in a second position, permits the outwards movement of the button to a rewinding and resetting position.
