The water-resistant watch case includes at least one crystal mounted on an upper side of a middle, a fastening gasket being disposed between an upper annular inner wall of the middle and an upper annular outer wall of the crystal. The crystal includes an annular peripheral surface below the upper annular outer wall inclined at a defined angle smaller than 90° in relation to an axis perpendicular to a plane of the watch case to come into direct contact against an annular inner surface of the middle inclined at an angle similar to the inclination of the annular peripheral surface and below the upper annular inner wall of the middle. The annular peripheral surface and/or the annular inner surface of the middle comprise a domed contact portion for a contact on an annular contact line between the two surfaces.

An electronic watch may include a housing defining a side wall having a through-hole and a crown assembly including an actuation member. The actuation member may include a crown shaft extending through the through-hole and having an exterior portion defining an input surface and a crown ring coupled to the exterior portion of the crown shaft and electrically isolated from the crown shaft. The crown assembly may further include an optical encoder component attached to the actuation member and defining a group of optical features. The electronic watch may further include an optical detector configured to detect rotation of the crown assembly by detecting motion of the group of optical features and an electrocardiograph sensor comprising a sensing component. The sensing component may be conductively coupled to the actuation member via a conductive path at least partially defined by the crown shaft.

The stem-crown of a water-resistant watch case includes a tubular stem inserted into a tubular opening of a middle part of the watch case, and a crown including a first portion connected in part to the stem and a second handling portion. The first portion includes an annular contact surface inclined at less than 90° with respect to a longitudinal central axis of the stem-crown starting from the first portion towards the outside of the second portion. In a rest position, the first portion is in contact against an annular receiving surface of the middle part of complementary shape to one end of the tubular opening towards the outside. The crown further includes a washer under a bearing part of the first portion and contacting the stem, being configured to bear in an annular slot of the middle part between the tubular opening and the annular receiving surface.

A watch case, including an orientable screwed crown including axially movable, a subassembly including a setting body including a pattern, a tube suitable for being axially inserted into a hole of the case and including an axial indexing profile engaging complementarily with a complementary axial indexing profile of the hole, and the indexing profile is a cone of apex angle less than 15°, arranged to engage by friction with the complementary indexing profile of the hole.

A screw-down orientable crown (200) for watch case (100), including a tube (11) that can be axially inserted into a case housing (90), and a handling body (1) including a pattern (19) and a relief (15) extending axially and, in the coupled position, cooperating for indexing the pattern (19) relative to the case (100) with a complementary relief (55) that a fixed pipe (5) includes which is pushed back from the body (1) by a spring (12), and including an axial stop (3) fixed to the body (1) to axially trap the fixed pipe (5) with a stroke corresponding to the deformation of the spring (12) to enable the disconnection, by a compression of the body (1), between the relief (15) and the complementary relief (55), which relief (15) is carried by a trunnion (4) integral with the body (1) and which is inside the fixed pipe (5).
