Abstract: This invention is directed to a watch which includes a rotating bezel with a ring-shaped part projecting from its lower surface and with a serrated edge at the end. This ring-shaped part is fitted into an indentation in the rim and its toothed part meshes with a pinion with an axial aperture of square cross-section fitting onto a segment of complementary cross-section on the winding stem. The pinion is located in a case open laterally on the external surface of the rim and maintained in this case by a shutting device. The winding stem can be axially moved between at least two positions while remaining constantly meshed with the rotating bezel by means of the pinion allowing the rewinding or setting of the watch by rotating the bezel.
