A. Lange & Söhne Datograph

About this reference

The A. Lange & Söhne Datograph reference 403.035 in platinum was produced between 1999 and 2012. Collectors prioritize this reference as the original execution of the Datograph, featuring a 39mm case and the manual-wind caliber L951.1. The movement is noted for its flyback chronograph complication, instantaneous jumping minute counter, and intricate depth created by German silver bridges and hand-engraved balance cocks. The dial follows a symmetrical layout with a signature oversized date at twelve o'clock and silver sub-dials against a black background. On the secondary market, prices typically range from $85,000 to $110,000 depending on condition and the presence of original documentation. A notable production variant is the "Meter" dial, found on early examples, which features a tachymeter scale starting at 400 rather than the standard 300, often commanding a premium at international auctions.
