Abstract
A watch case comprising a rotary bezel, first and second angular positioning markings, one set secured to the bezel and the other set to the case middle and elastic means in the form of a closed-loop spring tending to place the positioning markings into engagement with one another. These markings are distributed with numbers of spacings one of which is a multiple of the other and the outlines of which extend in a plane parallel to that of the bezel. Guide means are engaged with the markings having the smallest number of spacings, in order simultaneously to exert on these markings radial pressures directed toward the other markings.
