The watch case comprises a bezel (2) with cylindrical base (9) and a back/middle (1) to which are fixed the horns. The cylindrical base of the bezel is pushed into a cylindrical opening of the back/middle. It is fixed with screws (3) provided, immediately beneath the screw head, with a groove in which an O-ring (7) is placed. The groove is bounded, on the side opposite the screw head, by a rim (10). The cylindrical base (9) has an analogous groove (5) provided with an O-ring (6). The two rings experience only the lateral pressure of the walls of the back/middle. <IMAGE>
