A. Lange and Sohne 403.041 Datograph 18K Yellow Gold "YELLOWJACKET" RARE

The A. Lange and Sohne Datograph ref. 403.041, colloquially known as the “Yellowjacket,” is a remarkably rare iteration of Lange’s iconic big‑date flyback chronograph, an extremely rare variant of the Datograph only made for 2 years and never officially included in the Lange catalog or price lists, produced in approximately 30 examples between 2008 and 2009. Housed in an elegant 39 mm 18K yellow gold case just 12.8 mm thick, this model was never formally catalogued or listed in price lists, adding to its mystique among collectors. At its heart beats the illustrious manually wound calibre L951.1, featuring a column‑wheel chronograph with flyback function, large date, and small seconds—exemplifying Lange’s peerless engineering and finishing. The high‑contrast black dial with silver subdials and applied gold markers offers both legibility and visual drama, a hallmark of the Datograph’s design language. Its scarcity and boutique‑level exclusivity make it a highly coveted piece for enthusiasts of modern haute horlogerie. The movement’s German silver construction, visible through the display back, showcases traditional hand‑finishing techniques such as black‑polished levers and chamfered edges, reinforcing its technical pedigree and as a historical touchstone in Lange’s chronograph lineage. Excellent Condition with A. Lange and Sohne box.
