ABSTRACT:
The invention proposes a watch comprising a case which includes a middle part, a crystal and a display dial. The crystal includes an outer radial collar which abuts axially against the middle part and which is held axially against the middle part by means of a bezel. The bezel includes a lower annular radial surface which abuts axially against the top face of the collar. According to one feature of the invention, 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.
