The Datograph was introduced in 1999, the Datograph UP/DOWN in 2012. These four pictures will show you the Datograph UP/DOWN in a way you have not seen the timepiece before. Just stunning!
There is no need to introduce the A. Lange & Söhne Datograph and Datograph UP/DOWN, today both hand-wound chronographs are iconic and much sought after timepieces.
My friends from Lange just sent me these four seductive pictures and I thought you might want to see them too …
In the Datograph Up/Down, harmony relies on the interaction of contrasts …
I like them!
