A safety valve for a watch including a head that is movably mounted on a tube and able to move between an open position and a closed position, the tube including in its internal volume a first spring and wherein the tube is provided on an external face with a cam surface allowing a manual movement and an automatic movement of the head into its open position, after the first spring, the tube includes a second spring having a higher stiffness than that of the first spring.

An automatic safety valve for timepieces includes a valve head housed inside a tube. The valve head includes a lip seal disposed around a core and arranged so that a lip is squeezed against a wall of an outlet channel to disengage from the area to allow pressure compensation between the interior and exterior of a case during excess pressure inside the case, and pressed against the area to seal the interior of the case during excess pressure outside the case. The safety valve further includes an additional sealing element inside the outlet channel. The additional sealing element includes a membrane that is permeable to gases and to establish fluid communication from the interior of the case towards the exterior, when the internal pressure exceeds a predetermined value, and impermeable to liquids flowing from outside the case towards the interior of the case.

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.
