In addition to the capabilities of a pure chronograph, the double chronograph also features a split-seconds mechanism. On starting the chronograph, two centrally rotating stopwatch hands – mounted one above the other – are set in motion. An additional push-button at “10 o’clock” is used to stop the upper hand, while the lower hand continues to move until the regular stop button at “2 o’clock” is pushed. This enables two short periods of time to be measured simultaneously. When the rattrapante pushbutton is activated a second time, the split-seconds hand is brought into renewed synchrony with the chronograph hand – irrespective of whether this has been stopped or is still moving.
