Easily one of the most complex chronographs to date, the A Lange & Söhne Triple Split sets a new benchmark for chronographs; it is the world’s first triple-rattrapante chronograph capable of tracking comparative time measurements in multiple increments for up to 12 hours. The 567-part in-house movement, caliber L132.1, was several years in the making, and is the long-awaited sequel to the iconic 2004 Double Split. There are 10 hands on the watch, including three rattrapante hands for the seconds, minutes and hour totalizers. All hands are color coded so that when split-seconds timing is activated, all functions are easy to read. A major challenge for the master watchmakers was enabling the three hand-pairs to operate in unison collectively, or separately on their own. This required a host of new parts and development of a patented disengagement mechanism that ensures accuracy of both chronograph and rattrapante tracking. Just 100 pieces will be made.
