Abstract (en)
[origin: WO03009068A1] The invention relates to a chronograph consisting of a drive mechanism which turns a chronograph indicator (47) shaft (28) during the manual operation of a first positioning element (44), and of a catch-up indicator (48) shaft (5) which is coaxial to the chronograph indicator shaft (28) and which can be driven by the chronograph indicator (47) in a superposed manner. According to the invention, a second heart (29) is arranged on the chronograph indicator shaft (28) to return the chronograph indicator (47) to the original position. The chronograph indicator shaft (28) and the catch-up indicator shaft (5) are interconnected by means of a catch-up heart (30) of a frictional coupling in a rotationally fixed manner. A catch-up wheel (6) is arranged on the catch-up indicator shaft (5), which can be gripped by the arms (1,1') of a catch-up gripper using spring bias and which can be rotationally blocked by friction or a form closure. The invention also comprises a moveable coupling element which can be moved between a blocking position and a release position by the manual operation of a second positioning element (46). Said coupling element can remove the gripping arms (12,12') from the rotational blocking position on the catch-up wheel.
