Abstract: A chronograph with a chronograph driving mechanism through which a chronograph hand staff of a chronograph hand can be driven in rotation, with a rattrapante hand staff, arranged coaxially to the chronograph hand staff, of a first rattrapante hand that can be driven in superimposed position with the chronograph hand. The chronograph hand staff and rattrapante hand staff are connected to one another in locked-rotation, wherein the rotation of the rattrapante hand staff can be blocked in order to display a split time. A second rattrapante hand is connected frictionally with a second rattrapante hand staff arranged coaxially to the chronograph hand staff. The chronograph hand and the second rattrapante hand can be driven in movement synchronously in superimposed position, wherein the rotation of both rattrapante hand staffs can be blocked independently from one another in order to display two different lap times.

Abstract: 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.

Abstract: The invention relates to a chronograph having a chronograph drive by means of which, when a first actuating element 44 is actuated manually, a chronograph-hand stem 28 of a chronograph hand 47 can be driven in rotation, and having a rattrapante-hand stem 5, coaxial with the chronograph-hand stem 28, of a rattrapante hand 48 which can be driven in an overlapping manner with the chronograph hand 47. In this case, a seconds heart cam 29 for resetting the chronograph hand 47 is arranged on the chronograph-hand stem 28, and the chronograph-hand stem 28 and rattrapante-hand stem 5 are connected to one another in a rotationally fixed manner by a rattrapante heart cam 30 of a force-fitting coupling. A rattrapante wheel 6 is arranged on the rattrapante-hand stem 5, can be encompassed under spring prestressing by the gripper arms 12, 12′ of a rattrapante gripper and can be blocked against rotation by a friction or form fit.

Abstract: An arrangement for setting the minute hand of a timepiece which has at least minute and second hands 29, having a setting stem 1 which can be moved axially out of a normal position into a setting position. In this case, upon movement of the setting stem 1 out of the normal position into the setting position, a zero setting drive of the second hand 29 can be driven such that it moves the latter into its zero position. By virtue of the setting stem 1 being moved out of the normal position in the direction of the setting position, it is possible to initiate operation of a spring-force-operated drive by means of which the zero setting drive of the second hand 29 can be driven such that it moves the latter into its zero position.
