Combining two of haute horlogerie’s most demanding complications within a single movement, the Datograph Perpetual demonstrates A. Lange & Söhne’s extraordinary technical capability. Its manually wound manufacture calibre integrates a column-wheel flyback chronograph with a perpetual calendar programmed to accurately display the date, day, month and leap year until the year 2100, requiring correction only during century years not divisible by 400. Despite this remarkable complexity, the dial remains exceptionally balanced, preserving the unmistakable Datograph identity.

Behind the sapphire caseback lies one of the industry’s most admired movements, where every bridge, lever and spring is meticulously hand-finished according to traditional Glashütte standards. The visual architecture is as impressive as its mechanical performance, offering collectors an unparalleled appreciation of German watchmaking artistry while delivering exceptional precision and long-term reliability.
