A. LANGE & SOHNE. A VERY RARE AND IMPRESSIVE 18K WHITE GOLD LIMITED EDITION TRIPLE SPLIT FLYBACK CHRONOGRAPH WRISTWATCH WITH TACHYMETER AND POWER RESERVE

Part of the Saxonia Collection and made in a limited edition of only 100 pieces in white gold, the Triple Split chronograph represents not only a major achievement and technical accomplishment for Lange & Söhne but also in the history of watchmaking, showcasing a complication that has never been done before. The Triple Split Chronograph is a true first, a rattrapante or split seconds chronograph that is capable of measuring and comparing the time of two events running concurrently, and even more impressively, of up to twelve hours' duration made possible with, in addition to the central split seconds chronograph, rattrapante mechanisms for both the minutes and hours. Timings can be made to an accuracy of one-sixth of a second. This awe-inspiring masterwork of horological engineering allows collectors the rare opportunity to absorb and fully appreciate the genius of Lange & Söhne, without doubt one of the greatest watchmaking houses in the world.

How it works
Like the traditional split-seconds chronograph, the Triple Split has two central chronograph seconds hands which run together in unison when the chronograph is activated until the split function is used. When the split button is pressed, the blued hand stops, while the other white gold hand continues to run. If the split button is pressed again, and the stopped hand then jumps to rejoin the other hand and they continue to run together once again. This Triple Split model also has split hands for both hours and minutes, when the split button is pressed these subsidiary hands rejoin simultaneously in unison with the seconds so that one of the two timing sessions is halted. The Triple Split is, like its predecessor the Double Split, also a flyback chronograph.
