The Double Split stands alone in the pantheon of chronographs. When it was launched in 2004, it was the first mechanical chronograph with a double-rattrapante function, two rattrapante hands – one for the seconds and one for the minutes counter.

Its additional flyback minute counter allows for the use these rattrapante functions in a truly meaningful way, namely for events that last up to 30 minutes - as opposed to conventional rattrapante mechanisms that could only measure times of up to 60 seconds.

The in-house Caliber L001.1 is composed of 465 hand-finished parts. It features a precisely jumping chrono minute counter and a jumping rattrapante minute counter. During an ongoing time measurement, the flyback function will immediately stop and reset the chronograph hands (and, with them, the rattrapante hands if they are still running) with only one press of a button. A new measurement begins instantaneously when the button is released again. This skips the otherwise necessary "stop" and "reset" steps."
