A. LANGE & SOHNE. A RARE AND IMPRESSIVE PLATINUM DOUBLE SPLIT SECONDS FLYBACK CHRONOGRAPH WRISTWATCH WITH POWER RESERVE

Until the launch of A. Lange & Söhne's 'Double Split', the French term 'rattrapante' described the ability of a split seconds chronograph's superposed seconds hand to 'catch up' with the main sweep seconds hand. Comparative time measurements were limited to 60 seconds, and could not always be used in an appropriate way.

Lange's 'Double Split', the world's first flyback chronograph with a double rattrapante mechanism, opened up a new dimension in mechanical time measurement. Beyond the ordinary stopwatch functions of a conventional chronograph, it can also handle lap-time measurements, time comparisons, and fastest/slowest lap measurements. Its additional flyback minute counter makes it possible for the first time to use these rattrapante functions in a truly meaningful way, namely for events that last up to 30 minutes.
