Abstract
A water-resistant watch case of a diving watch, includes at least one back mounted on a lower side of a middle part, and a crystal mounted with a fastening gasket on an upper side of the middle part. The back includes an annular bearing surface for coming into contact with an inner annular surface of the middle part of a shape complementary to the bearing surface during mounting of the back on the middle part. The annular bearing surface and the inner annular surface are inclined towards the inside of the watch case at a determined angle less than 90° relative to a central axis perpendicular to a plane of the watch case so as to distribute stresses between the back and the middle part due to the water pressure during a dive. The annular bearing surface and the inner annular surface are conical in shape.
