The bezel closure device comprises bezel tube halves rigid with the ends of a metal bezel. The tube halves define contiguous bases adapted to contact each other to close the bezel. Each tube half includes a throughgoing hole, which is threaded internally to receive a screw, including a shank, formed with threads at a lower portion thereof. A spring washer prevents the screw from becoming loose in the throughgoing hole.
