A. Lange and Sohne 403.031 Datograph Black Dial 18K Rose Gold on WELLENDORFF BRACELET

The A. Lange and Sohne Datograph reference 403.031 Black Dial in 18K Rose Gold represents a benchmark in modern chronograph design and horological craftsmanship, first launched in the early 2000s. This iconic model is powered by the revered manual-wind L951.1 caliber, distinguished by its precise column wheel mechanism, jumping minute counter, and the visually striking flyback chronograph function. Presented in an impeccably finished 39mm rose gold case, the watch features a deep black dial contrasted by large luminous indices and the signature oversized date display, inspired by the Semper Opera House's clock in Dresden. Widely considered a modern classic among serious collectors, the 403.031 is celebrated for its architectural movement visible through the sapphire caseback, showcasing hand-engraved bridges and traditional Glashutte finishing. The harmonious blend of technical ingenuity and aesthetic refinement places the Datograph in a league of its own in the luxury chronograph world. Frequently nicknamed the "Dufourgraph" by enthusiasts, it is admired by legendary watchmaker Philippe Dufour. Its rarity and elevated horological pedigree make it a cornerstone for any high-end, contemporary collection. The bracelet is crafted from 18K rose gold Wellendorf bracelet and the enduring appeal of the Datograph 403.031 is ensconced in its movement architecture, finishing, and historical relevance.
