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.
Claims12
A watch comprising a casing fitted with a rotating bezel, and housing a watch movement a toothed annular part comprising teeth, a winding stem delimiting a segment of polygonal cross section situated outside the watch movement, a pinion furnished with an aperture of complementary cross section to a cross section of said segment, engaged thereon, said pinion comprising pinion teeth which mesh with said teeth of said toothed annular part, forming a kinematic link between the rotating bezel and the winding stem, wherein said pinion is positioned axially between two stops integrated with the casing, and said segment of polygonal cross section of the winding stem having a length chosen so as to enable said winding stem to be moved axially between at least two positions, comprising a winding position for winding and a time-setting position for time-setting while maintaining the kinematic link between the rotating bezel and the winding stem by way of the said pinion.
