A pressure-relief valve (1) for a watch case comprising:
- a tube (2) intended to be fastened to said watch case, said tube (2) defining an axis A designating an axial direction,
- a head (3) mounted movable in rotation and in translation about and along said axis A, said head (3) being able to adopt a first axial position, which is an open position, a configured to allow a gas flow between the inside and the outside of the watch case and a second axial position, which is a closed position, where the gas flow between the inside and the outside of the watch case is prevented, said head (3) being provided with a cover (3a), which is a first cover, and with an axial skirt (3b), which is a first axial skirt, delimiting a recess, which is a first recess, within the head (3),
- a first insert (4) mounted within said first recess of the head (3), and
- a first sealing gasket (6) arranged in the head (3) and on an inside of the first insert (4) with, in a direction perpendicular to the axis A, the first insert (4) being between the first sealing gasket (6) and the head (3),
- wherein the head (3) is mounted on the tube (2) via the first insert (4) and wherein the head (3) is fastened to said first insert (4) by fastening means (8) comprising a screw thread and/or a glue.
