About the A. Lange & Söhne Datograph
A. Lange & Söhne relaunched as a modern manufacture in 1994 after decades of suppression, and the Datograph debuted in 1999 as an immediate benchmark for mechanical chronograph construction, celebrated for its precisely jumping minutes counter, its flyback function, and the brand's signature outsize date display. The Datograph Up/Down references such as 405.028 in white gold with a blue dial and 405.031 in pink gold with a black dial layer a power-reserve indication onto that foundation, while the Datograph Perpetual references such as 410.038 add a full perpetual calendar that accounts for month lengths and leap years automatically. At the apex of the collection sit the Datograph Perpetual Tourbillon references including 740.056FE in white gold, 740.036FE in platinum, and the rare 740.055FE in Honeygold Lumen, uniting every major complication the manufacture offers in a single 41mm wristwatch. Across all references the movement is finished to Glashütte tradition with three-quarter plates, Glashütte ribbing, and hand-engraved balance cocks that distinguish Lange from virtually every other watchmaker.
What to Look For
Buyers comparing Datograph references should note that the Up/Down models differ from the Perpetual by the presence of a perpetual calendar and that the Perpetual Tourbillon adds a flying tourbillon, placing them in a significantly higher tier of complexity and value. Case material drives pricing meaningfully across the line, with platinum and Honeygold examples commanding premiums over pink and white gold, while limited Lumen dial variants such as the 405.034 and 740.055FE are especially sought after for their luminescent skeletonized presentation. Condition, box, and papers are critical for any pre-owned Lange purchase, and factory service history adds measurable value given the complexity of these movements.
Frequently Asked Questions
What is the difference between the Datograph Up/Down and the Datograph Perpetual?
The Datograph Up/Down, seen in references like 405.028, 405.031, and 405.035, combines a flyback chronograph with a power-reserve display indicated by the Up/Down subdial. The Datograph Perpetual, such as reference 410.038, adds a full perpetual calendar to that chronograph movement, automatically tracking date, day, month, and leap year without manual correction.
What case materials are available in the A. Lange & Söhne Datograph collection?
The Datograph collection is offered in white gold, pink gold, platinum, and the proprietary Honeygold alloy developed exclusively by A. Lange & Söhne. Platinum and Honeygold references, including the Datograph Perpetual Tourbillon 740.036FE and 740.055FE, are particularly rare and tend to attract the strongest collector demand.
