Reasons to Bid

The A. Lange & Söhne Datograph Ref. 403.032 is widely regarded as one of the most important chronographs in modern horology. First introduced in 1999, it set a new benchmark for high-end mechanical chronographs with its architectural movement design, instantaneous jumping minutes counter, and unparalleled level of finishing. This reference, presented in 18k rose gold, is a desirable configuration of the original Datograph series. Powered by the legendary in-house Caliber L951.1, a hand-wound movement celebrated for its technical ingenuity and aesthetic mastery. Features include a column-wheel chronograph, flyback function, jumping minute counter, and a 36-hour power reserve. Through the sapphire caseback, the movement reveals a breathtaking composition of German silver plates, hand-engraved balance cock, blued screws, gold chatons, and an impeccably constructed chronograph mechanism considered by many collectors to be the most beautiful chronograph movement ever produced.
