Sub-assembly of external parts for a watch, comprising a water-resistant joint between a first and a second component, which are screwed, one on the other, the first component supports a first inclined toothing, which cooperates with a second inclined toothing of the second component, the first component or second component, or a second ring interposed between them comprises a zone which is elastically deformable under the action of a relative rotation between the first and the second component which is caused by an external force, and the deformation range of which allows compression of the elastically deformable zone allowing clearance of the teeth tips during the relative rotation and a release of this zone, allowing return to cooperation of the tips and the hollows of the teeth in a new relative angular position.

A pressure-relief valve (1) including: a tube (2) intended to be fastened to a watch case, a recessed head (3) mounted movable in rotation and in translation about and along the axis of the tube (2), the head (3) being able to adopt a first axial position where a gas flow could be performed between the inside and the outside of the watch case and a second axial position where this gas flow is prevented, a first insert (4) mounted within the recess of the head (3), the valve (1) being 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) including a screw thread and/or a glue.

A sealing system for a case of a timepiece, including: a first seal intended to be inserted between a middle on one side and a ring and a glass on the other side, a second seal intended to be inserted between a middle and a glass, the first and second seals being two distinct seals, in particular two independent seals or two separate seals, and/or the first and second seals being made of two distinct materials.

A diving watch includes a first device for displaying the current time and a second device for analogically displaying a diving duration. The second device includes a hand dedicated to the indication of a diving duration and a rotating bezel provided with a visible face including a time scale including time graduations. The bezel cooperates with the dedicated hand, in particular continuously animated with a uniform rotational movement, by displaying an instant value of the diving duration.

A sub-assembly of external parts including, coaxially with a first component and a second component compressing together a sealing and friction joint, and interposed therebetween, a bolt securing them together by axially blocking the first component, and a lower surface of which lies, in the assembled position, in the vicinity of an upper surface of the second component, which bolt includes a lower relief protruding axially from this lower surface towards the second component, arranged to either complementarily cooperate with an oblong groove which is partially of revolution that the upper surface includes, and interrupted by a stopper limiting the angular travel between the second component and the bolt within a turn, or else to constitute an angular stopper to an upper relief protruding from the upper surface of the second component and extending axially towards the bolt.

A method for manufacturing gasket seals by producing, through machining operations, a plurality of cuts in an assembly (10) produced by at least two identical joined tubes (20), each tube (20) extending along a longitudinal axis between two ends, the end of one tube (20), referred to as “first end” (21), having a shape complementary to the shape of the end of the other tube (20), referred to as “second end” (22), so that said first and second ends (21, 22) cooperate by complementarity of shape.
