Watchfinder & Co. presents:

Rattrapante, doppelchronograph, double chronograph, split seconds—whatever you call it, it’s the daddy of chronograph complications. Except that it’s not, because the Double Split from A. Lange & Söhne takes this already incredible chronograph mechanism to next level. Take a look and see what I mean.

DOUBLE SPLIT
In a race against time
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.
The DOUBLE SPLIT timepiece in pink gold features two chronograph hands which can run together and separately.


The upper button in the right-hand case flank starts and stops the chronograph hands, the lower one resets them to zero. The flyback function is activated when the lower button is pressed while the chronograph hands are running. This allows the hands to be stopped, reset to zero and restarted for a new measurement in one single step. When the button in the left-hand case flank is actuated, the rattrapante hands will stop to display a first intermediate time. This action reveals the rattrapante hands because previously, they were hidden beneath the running chronograph hands. When the button is pressed again, the rattrapante hands catch up with the chronograph hands and run synchronously with them.
