Description

A. Lange & Söhne introduced the first Datograph, combining the chronograph and perpetual calendar in one watch, and was one of their first in-house-developed chronograph watches. Until 2012, the Datograph was upgraded with an Up/Down feature, which has a power reserve up to 60 hours.

The watch is in new and excellent condition. The movement is running at the time of cataloging, however, it was not tested for the accuracy of time or duration of the power reserve and may need service at the buyer's discretion.
