The Datagraph Perpetual Ref. 410.025 in platinum was introduced by A. Lange & Söhne in 2006 as the perpetual calendar version of the Datograph chronograph, the brand’s first wristwatch with a combination of a chronograph and perpetual calendar. The brand produced watches in platinum with a white silver-plated dial until 2011. In 2009, the new Datagraph Perpetual Ref. 410.030 in white gold with a grey dial was introduced (the present reference). It featured an important design as it was the first watch in the Lange collection with a combination of white gold and a grey dial. This reference turned out to be short-lived, with A. Lange & Söhne deciding to discontinue both of these references as early as 2010, though they remained in production until 2011. They were replaced by a new model line 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. The first model to feature the new dial design was Ref. 410.032 in rose gold with a silver-plated dial, while the winning combination of white gold and a grey dial reappeared in the collection in 2018 as reference 410.038.
This reference is one of the rarest among the Datograph Perpetuals. Christie’s reports it was produced for just two years and fewer than 100 pieces were made.
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 caliber L952.1 of the present reference is built based on Datograph’s L951.1 caliber. Both are regarded as being among the most beautiful chronograph movements of the modern era, with outstanding quality in the finishing of the parts and once praised by the independent watchmaker Philippe Dufour, the acknowledged guru of traditional fine finishing. Particularly noteworthy are the design and high-end finishing of the chronograph mechanism of the present reference, featuring bridges in untreated German silver, multiple levers and flat steel springs that control the chronograph functions via the traditional column wheel. One should note the four jewels in screwed gold chatons, a typical high-end feature for Lange wrist- and pocket watches.
The design advantages of caliber L952.1 undoubtedly include a large balance with adjustment eccentrics, a hairspring with Breguet overcoil, beautifully curved levers and flat springs (especially the chronograph intermediate wheel lever), and the presence of steel parts with black polishing – these include the caps on the escape wheel and fourth wheel shafts, a column wheel and various other parts. In addition, the gold chatons received mirror polishing. Overall, the meticulous finishing with straight grinding, Glashütte stripes, perlage, blued screws, polished bevels, a swan neck micrometer regulator, and engraved and gilded inscriptions, in addition to those already noted above, makes the movement incredibly eye-catching, while the traditionally hand-engraved balance cock makes this watch feel like one of a kind.

Ref. 410.030 is one of the rarest versions of the Datograph Perpetual, while at the same time being considered extremely elegant and subtle due to the rare combination of its grey dial and white gold case, which was first used by A.
