Che dire? magari me lo portasse Babbo Natale...
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.
