  • Patent number: 11714384
    Abstract: 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.

  • Publication number: 20230195041
    Abstract: 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.
