The back 2 is annularly thinned at 10 so as to provide elasticity to the collar 7. The movement 5 is held by a frame 16 snap-fitted inside the crystal 1, 4. A combined bezel and caseband 15, 3 snaps on to the crystal body 4, the conical part 13 of the crystal 1, 4 resting on the edge of the dial 14. A winding stem 18 passes through the caseband 3, the crystal 4 and the frame 16 and is provided with a washer 19.
