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
Hi Stephen, glad you like the larger size. For me this increase in size makes it easier to renounce the Lange watches which I often like(d) due to their moderate diameters, but which are beyond my reach otherwise. The Grand Seiko LE with 36 mm would be just my dimension . Best regards and "Servus!", anaesdoc
... 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
