Patent ID: 7384189

Claim:
A watch including a case which includes a middle part, a crystal, a bezel which is snap fitted in the middle part-and a display dial, of the type wherein the crystal includes an outer radial collar which abuts axially against an annular radial bearing surface of the middle part and which is held axially against the middle part by means of a lower annular radial abutment surface of the bezel which abuts axially against the top face of the collar and an annular heel portion which is driven axially, from the top downwards, into the middle part such that the outer peripheral wall of the heel portion is pressed radially against the inner wall of an outer peripheral edge of the middle part, wherein said radial abutment surface is arranged in one section of bezel located above the heel portion and is substantially aligned axially with the annular radial bearing surface of the middle part, wherein the collar includes a convex outer peripheral surface which is generally complementary to a concave inner surface of the bezel arranged opposite, underneath the radial abutment surface of the bezel and which abuts radially against said inner surface in the event of an axial shock applied to the crystal, and wherein the inner surface of the bezel is formed by the inner wall of the heel portion.
