SJX's announcement of the A. Lange & Söhne Datograph Auf/Ab marks a significant moment for collectors, detailing the evolution of an iconic chronograph. This report is crucial for understanding the subtle yet impactful changes from the original, such as the increased case size, extended power reserve, and new dial aesthetics, providing a valuable first look for enthusiasts.
Lange just unveiled the Datograph Auf/Ab. The most evident changes over the outgoing model is the new 41 mm case and a power reserve of 60 hours thanks to a larger barrel. Also the dial now has batons instead of Roman numerals. The current model on the other hand has a 36 hour power reserve and a 39 mm case.
The Datograph also now has the in-house Lange balance wheel with adjustable weights.


The pictures indicate Lange has retained the classic Datograph proportions though I'm unsure about the baton indices. I'm definitely looking forward to seeing this in a few weeks in Geneva.

I think it's going to get mixed reviews, but well to each his own! Stephen
I do not like the fact that the hands still are luminous though. Wish they had taken that awful thing away! Stephen
... but not sure of the larger and even thicker case... Have to see in person. At least they kept the Dato DNA well enough. Ken
Lots of DNA left. - SJX
I think it is a great evolution. First of all, it is not surprising, the changes were expected: the case diameter and the increased power reserve, especially after the new 1815 chronograph. Secondly, the watch is really beautiful. Its enlarged case makes it slender and all the original Datograph spirit is preserved like the triangle created by the date display the subdials, the PR indicator remaining very discreet. I consider this new Datograph as a very worthy evolution with more than welcome i
I like this update. This was very easy to get wrong and with the careful size update and the appreciated improvements to the movement I think they have done a great job, even though I will still happily wear the original for now. Best Andreas
