Abstract
A rotating bezel (18) is hooked on a fixed ring (17) intended to be fixed to the frame of the casing. This bezel (18) comprises a toothed rack (21) in which is engaged the free end (22b) of a positioning spring-wire (22) whose other end (22a) is elbowed and engaged in a hole (23) of the fixed ring (17). This spring-wire (22) comprises three segments, two end segments (22c, 22d) practically straight and tangential to a circle concentric with the bezel (18) and an intermediate curved segment (22e) with its center of curvature inside the bezel (18) but of radius substantially smaller than that of the bezel. The shape of the spring (22) permits the forces necessary to rotate the bezel (18) in the two directions to be made practically equal.
