Unveiled in 1999, the Datograph quickly established A. Lange & Söhne as one of the pre‑eminent makers of chronograph wristwatches, its movement and design hailed as among the finest of the modern era. Building upon this success, the maison expanded the line in 2006 with the introduction of the Datograph Perpetual in platinum, presented at the Salon International de la Haute Horlogerie (SIHH). Produced for only five years, until 2011, the model has since become a coveted reference, admired for both its technical mastery and enduring design.

The watch combines a solid rhodium‑silver dial and 41 mm platinum case, producing a refined monochromatic aesthetic. Subtle accents—a hint of blue within the day/night indicator and moon‑phase aperture—echo the blued steel hands in the subdials, lending quiet vibrancy to the otherwise restrained palette. A hallmark of the Datograph Perpetual lies in this juxtaposition: the delicacy of its dial balanced against the unmistakable gravitas of its case.

The present example belongs to the first generation, distinguished by its II, VI, and X Roman numerals, a feature later replaced by baton markers in rose and white‑gold successors. Preserved in “like-new” condition and offered with its complete set of accessories, it stands as both a flagship of the manufacture and a rare opportunity for the discerning collector. With production limited and examples seldom appearing publicly, the Datograph Perpetual underscores A. Lange & Söhne’s enduring commitment to traditional Saxon watchmaking—a legacy that now spans more than 175 years.
