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 …
Wow!
Perfect pictures!

No for sure not! ALS simply celebrates traditional watchmaking and does what others stopped to do …
Ok, fine.
But how do they evolve? And if they do not evolve, they might get stagnant.
They evolve but not in terms of the frequency of the balance wheel. The latter is not all to make a good movement, it´s just one piece of the puzzle …
They are nice pictures! So, Alexander, what is the up/down feature?
