Claim:
A chronograph comprising: a dial, a chronograph hand staff that can be driven in rotation, connected with a chronograph hand, a first rattrapante hand staff, arranged coaxially to the chronograph hand staff, connected with a first rattrapante hand, wherein the chronograph hand and the rattrapante hand can be driven in movement synchronously in a superimposed position and wherein the rotation of the rattrapante hand staff can be blocked in order to display, together with the rattrapante hand a first lap time, and a second rattrapante hand staff, connected with a second rattrapante hand, arranged coaxially to the chronograph hand staff, wherein the chronograph hand and the second rattrapante hand can be driven in movement synchronously in a superimposed position, wherein the rotation of the second rattrapante hand staff can be blocked independently from the first rattrapante hand staff in order to display with the second rattrapante hand a second lap time, and a rattrapante gripper associated with each rattrapante hand, said gripper being actionable by way of an activating element to selectively either block or release a rattrapante wheel associated with the corresponding rattrapante hand staff, such that, while the chronograph hand is running, each of the first and second rattrapante hands can be released from a blocked position to continue to run synchronously with said chronograph hand in a superimposed position.
