The water-resistant watch case includes at least one crystal mounted on an upper side of a middle, a fastening gasket positioned 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 an angle smaller than 90° in relation to an axis perpendicular to a plane of the watch case. The peripheral surface comes into 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 includes a domed contact portion for a contact on an annular contact line between the two surfaces.
