A. Lange & Söhne Double Split (Refs: 404.032, 404.035) (Add your watch to the comments below…)

The A. Lange & Sohne caliber L001.1 is an in-house mechanical double chronograph movement with a flyback function.

Originally introduced in 2004 in the A. Lange & Sohne Double Split, the cal. L001.1 is the first double rattrapante mechanical chronograph movement in the world.

In the manufacturer’s own words:

“The DOUBLE SPLIT is the worldʼs first mechanical chronograph with a double-rattrapante function. It features two chronograph hands and two rattrapante hands. Both pairs of hands can be stopped separately. Additionally, the stopped rattrapante hands can rejoin the still running chronograph hands. This allows purely mechanical comparative and intermediate time measurements of events lasting up to 30 minutes.”
