Abstract
A chronograph watch provided with a control arrangement for the three functions of start, stop and reset to zero. The purpose of the invention is to provide a more judicious distribution of the elements of the chronograph mechanism over the entire surface of the watch. This purpose is attained by means of a watch characterized in that it comprises a start and stop cam (48) and a reset-to-zero cam, both of these cams being constituted by superposed concentric rings arranged at the periphery of the watch movement, in that both of these cams (48, 49) exhibit respectively ratchet teeth (97) or notches (98a, 98b) on their outer periphery on which act two levers (100, 101) to drive the cams (48, 49) in rotation and teeth (96) or notches (99) on their inner periphery acting on the control levers for the gearing forming the chronograph mechanism.
