Abstract (en)
[origin: US6842403B2] The invention relates to a chronograph having a chronograph drive by means of which, when a first actuating element is actuated manually, a chronograph-hand stem of a chronograph hand can be driven in rotation, and having a rattrapante-hand stem, coaxial with the chronograph-hand stem, of a rattrapante hand which can be driven in an overlapping manner with the chronograph hand. A seconds heart cam for resetting the chronograph hand is arranged on the chronograph-hand stem, and the chronograph-hand stem and rattrapante-hand stem are connected to one another in a rotationally fixed manner by a rattrapante heart cam of a force-fitting coupling. A rattrapante wheel 6 is arranged on the rattrapante-hand stem, can be encompassed under spring prestressing by the gripper arms of a rattrapante gripper and can be blocked against rotation by a friection or form fit. A switching element which can be moved, by manual actuation of a second actuating element, between a blocking position and an unblocking position and by means of which the gripper arms can be lifted off from the rattrapante wheel, out of their rotation-blocking position.
