A. Lange and Sohne 405.035 Datograph Up / Down Platinum Black Dial

The A. Lange and Sohne Datograph Up/Down Ref. 405.035 in 950 platinum presents an extraordinary fusion of mechanical ingenuity and artisanal refinement. Housed in a 41 mm case measuring 13.1 mm in thickness, this model extends the Datograph lineage with a new power reserve display while preserving the revered architecture of the original. At its heart beats the manually wound caliber L951.6, offering an impressive 60‑hour power reserve, a flyback chronograph with precisely jumping minute counter, and the hallmark outsized date—all seamlessly integrated into a jet‑black solid silver dial. The movement, visible through the sapphire caseback, features German silver bridges, hand‑engraved balance cock and traditional gold chatons, a testament to Lange’s no‑compromise finishing. Introduced as part of the Saxonia family, this Datograph variant elevates collector allure through its material choice and technical evolution, embodying both sartorial elegance and horological significance.
