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.
