Abstract (en)
[origin: EP1947531A2] The device has a curved support face (16) carried by a tip (14) of a coupling lever (10) and co-operating with a cam (6) partially located above a crown wheel (1). The tip has a terminal portion (18) co-operating with an oval shaped peripheral surface (17) of crowns (2) of the crown wheel. An angular position of the cam determines penetration of gear teeth of an intermediate wheel (13) in gear teeth of a chronograph wheel (15). A screw fixes the cam in a desired angular position.
