The glass (9) is surmounted by a grid, the ends (10a) of the rods (10) which constitute it forming feet passing through the bezel (8), an outer calibre (4) and the back (7) of the case. These ends (10a), which are threaded, serve as ties for assembling the elements of the case, axial tightening being ensured by nuts (15) screwed onto these ends (10a). <IMAGE>
