About the A. Lange & Söhne Datograph Perpetual
A. Lange & Söhne re-established itself in Glashütte following German reunification and quickly became synonymous with the most rigorous standards in independent fine watchmaking, and the Datograph Perpetual stands as one of the brand's most coveted references. The model unites the Datograph's celebrated flyback chronograph architecture with a perpetual calendar that correctly accounts for months of varying lengths, all housed in precious-metal cases that underline its grand complication status. The Datograph Perpetual Tourbillon variants, references 740.036FE in platinum and 740.055FE in Honeygold, elevate the collection further by incorporating a tourbillon alongside the chronograph and perpetual calendar, placing these pieces among the most technically sophisticated wristwatches available anywhere. Across references, the movement finishing adheres to Glashütte tradition with three-quarter plates, hand-engraved balance cocks, and Rhodium-plated or German silver components visible through exhibition casebacks.
What to Look For
Buyers should understand that the Datograph Perpetual and the Datograph Perpetual Tourbillon are distinct tiers, with the tourbillon references commanding a significantly higher position in both complexity and market value, while case material — white gold versus platinum versus the exclusive Honeygold alloy — further differentiates pricing and collectibility. Reference numbers such as 410.038E for the standard 41mm white gold grey dial and the 740-series for the tourbillon variants are meaningful identifiers when verifying authenticity, confirming dial configuration, and assessing rarity. The Lumen designation seen on reference 740.055FE indicates a luminescent dial treatment that performs distinctively in low-light conditions, making it a particularly sought-after variant for collectors focused on dial artistry.
Frequently Asked Questions
What is the difference between the Datograph Perpetual and the Datograph Perpetual Tourbillon?
The Datograph Perpetual combines a flyback chronograph with a perpetual calendar, while the Datograph Perpetual Tourbillon adds a tourbillon regulator to that same complication set, making it one of the most complex mechanical watches produced by A. Lange & Söhne. The tourbillon variants carry 740-series reference numbers and are offered in materials including white gold, platinum, and the proprietary Honeygold alloy, each in very limited production runs.
What case materials are available in the Datograph Perpetual collection?
The collection is available in white gold, platinum, and A. Lange & Söhne's proprietary Honeygold, a warm-toned precious alloy developed exclusively by the brand. Case material is one of the primary factors driving value and rarity across the lineup, with platinum and Honeygold pieces typically representing the most exclusive configurations.
How can I verify authenticity when buying a Datograph Perpetual for sale on the secondary market?
Confirming the specific reference number, such as 410.038E for the white gold grey dial 41mm or the 740-series for tourbillon variants, against documented records is an essential first step in authentication. At Bizak and Co., every Datograph Perpetual undergoes professional inspection before listing, and buyers should always request original box and papers as well as an exhibition caseback inspection to confirm movement finishing consistent with Lange's known standards.
