This watch is the world’s first and only mechanical chronograph Which with a double-rattrapante function.
It features two pairs of stopwatch hands that can run together as well as separately. For the first time, they allow time comparisons, lap-time and reference-value measurements as well as fastest/slowest measurements of events that last up to 30 minutes.
It has two pairs of stopwatch hands which are gold-plated.The minutes that have elapsed are indicated by the respective precisely-jumping minute counter hand in the subsidiary dial on the right.
I think A. Lange & Söhne DOUBLE SPLIT is a fabulous watch,with a excellent dial and soft leather strap makes it become a milestone watch of A. Lange & Söhne.
