The Datograph Perpetual introduced two classic complications, a perpetual calendar and a chronograph. While this combination is typical for complicated pocket watches, it is rare for wristwatches, especially if the movement uses the traditional design of these two complications. In addition, as a sign of modern watchmaking artistry, the watch is equipped with a highly precise astronomic moonphase display, programmed to accurately display continuously for 122.6 years, and then to be adjusted by just one day. 

The present reference belongs to the second generation of Datograph Perpetual. The original, first-generation Datograph Perpetual Ref. 410.025 in platinum was introduced by A. Lange & Söhne in 2006 as a perpetual calendar version of the Datograph chronograph, and the brand’s first wristwatch with a combination of a chronograph and perpetual calendar. The brand produced Datograph Perpetual watches in platinum with a white silver-plated dial until 2011. In 2009, another first-generation Datograph Perpetual Ref. 410.030 in white gold with a grey dial was introduced. Both were discontinued in 2010-2011. In 2010, the brand announced the face-lifted second-generation version with a redesigned dial that no longer had the distinctive three Roman numerals at 2, 6 and 10 o’clock (features on the two early references), instead featuring applied baguette markers. Other technical specifications remained the same. The first model to feature the new dial design was the present Ref. 410.032 in rose gold with a silver-plated dial. In 2019, it was discontinued.
