Lot Essay

Until the launch of A. Lange & Söhne's Double Split, the French term rattrapante described the ability of the superposed hands of the split seconds chronograph 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.

Introduced in 2004, A. Lange & Söhne's Double Split, the world's first flyback chronograph wristwatch with a double rattrapante mechanism, opened up a new dimension in mechanical time measurement, marketed by the firm as; "The new Lange Double Split is absolutely peerless, because it not only has one, but two rattrapante hands - one for the seconds and one for the minutes to be stopped. What's more, both chrono hands and both rattrapante hands are flyback hands. The new era of chronography has begun."

Beyond the ordinary stopwatch functions of a conventional chronograph, the Double Split can also handle lap-time measurements, time comparisons, and fastest/slowest lap measurements. Its additional flyback minute counter allows for the first time to use these rattrapante functions in a truly meaningful way, namely for events that last up to 30 minutes - as opposed to conventional split seconds mechanisms that could only measure times of up to 60 seconds.

Its Lange L001.1 movement, a pinnacle of horological complexity, is composed of 465 hand-finished parts. Its balance beats at a frequency of 21,600 semi-oscillations per hour, allowing measurements to an accuracy of one-sixth of a second. Moreover, error-free readings are assured by the precisely jumping chrono minute counter and the precisely jumping rattrapante minute counter. During a continuing time measurement, the flyback function will immediately stop and reset the chronograph hands (and simultaneously 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, hence skipping the otherwise necessary "stop" and "reset" steps.

Available in pink gold and platinum, the model enjoyed immediate success amongst collectors.
