A. Lange & Söhne 384.031 Saxonia Moon Phase 40mm Rose Gold 384.031 BLACK BLACK CROCODILE

The Saxonia collection represents A. Lange & Söhne’s core philosophy of understated elegance and technical purity, and this 384.031 reference with a moon phase complication is a definitive modern execution of that principle. The 40mm case is crafted from solid 18-carat rose gold, featuring the brand’s characteristic polished and brushed finishing. The black dial provides a stark, high-contrast backdrop for the applied white gold baton indices and the subsidiary seconds dial. The moon phase display is positioned at 6 o’clock, its solid gold moon and starry sky aperture sharply defined against the grained finish of the dial. It is presented on a factory-supplied black crocodile leather strap with a matching rose gold pin buckle, completing a design that is both reserved and highly legible.

Powering the watch is the in-house, manually-wound Calibre L086.5. This movement is known for its robust construction and a power reserve of 72 hours. The moon phase complication is exceptionally precise, requiring a correction only once every 122.6 years. The movement’s finishing is a primary factor in the model’s collectibility, visible through the sapphire case back. It features the signature three-quarter plate made of untreated German silver, Glashütte ribbing, and hand-engraved balance cock. The escapement is regulated by a free-sprung balance wheel with a spring crafted in-house, ensuring high chronometric stability. This combination of a long power reserve and a highly precise, classic complication makes this a particularly sought-after configuration within the Saxonia line.

This specific watch is offered in mint condition, with no visible signs of wear on the case, lugs, or crystal. The black crocodile strap is original and shows minimal use. The watch is accompanied by its official papers, which confirm its authenticity and provide a record of its provenance. As a limited-production model from a manufacture that produces fewer than 5,000 watches per year, the Saxonia Moon Phase is inherently exclusive. Its position in the market is strong, appealing to collectors who value the brand’s technical execution and restrained design language over more ostentatious complications. The presence of full documentation and its exceptional state of preservation further solidify its status as a secure and desirable acquisition for a serious collection.
