A. LANGE & SÖHNE | DOUBLE SPLIT FLYBACK, PLATINUM DOUBLE SPLIT FLYBACK CHRONOGRAPH WRISTWATCH WITH POWER RESERVE INDICATION CIRCA 2015

Launched in 2004, A. Lange & Söhne's Double Split is the world's first fly back chronograph wristwatch with a double-rattrapante mechanism. The watch features four chronograph hands, two of which are set to a unique 30-minute register. More impressive than this, both chronograph hands and both rattrapante hands are fly back hands. The Double Split allows the user to measure and compare time intervals of up to 30 minutes, as opposed to a maximum of only 60 seconds, which distinguishes it from traditional split-seconds chronographs.

The watch weighs over 200 grams, yet remains wearable and elegant with its robust case and curved lugs. The dial is configured with legibility in mind, with its rattrapante hands differentiated in gold instead of blued steel. The most breathtaking feature of all is arguably to the reverse, where a sapphire crystal display back reveals the Double Split's mind-boggling and multi-dimensional movement. The elevation of the bridges render the movement close to a fine sculpture or a geological strata.
