Safety valve for watches

The present invention relates to a safety valve including: a tube intended to be fixed to a watch case, a hollow head mounted for rotation about the tube, a first element fixedly mounted with respect to the head and a second element integral with the head,
wherein the first element and the second element each include one or more passages allowing gas to flow, the rotational motion of the head allowing the passages of the first element and of the second element to be placed in communication for gas to escape from the interior to the exterior of the case in case of overpressure inside the case or, conversely, allowing the passages of the first element and of the second element to be moved out of alignment to prevent gas escaping.

Sealing device

A sealing device (100) for a watch (200) configured to be inserted into a primary space (201) comprised in a middle part (210). The sealing device (100) includes an insertion organ (110) configured to be inserted into the primary space (201), a first sealing elements set (120) configured to seal the primary space (201) between the middle part (210) and the insertion organ (110), and a sealing elements set (140) configured to seal a secondary space (131) between a drive organ (130) and the insertion organ (110).
