The A. Lange & Söhne Lange 31 Ref. 130.032 is a remarkable example of German haute horlogerie and the world’s first mechanical wristwatch designed to provide a power reserve of 31 days.
It's substantial 45.9 mm case is crafted from 18K rose gold and paired with an elegant alligator-leather strap. The solid-silver argenté dial features an oversized double-window date, an off center hours and minutes display, subsidiary seconds, and a prominent power reserve indicator.
The watch is powered by the manually wound A. Lange & Söhne Caliber L034.1, offering an extraordinary 744 hour or 31 day power reserve. Its two exceptionally long mainsprings are wound using a specially designed winding key, while a constant-force mechanism maintains consistent energy delivery and stable precision throughout the running period.
A sapphire crystal protects the dial, while the sapphire exhibition caseback reveals the elaborately hand finished movement. The A. Lange & Söhne Lange 31 Ref. 130.032 is an exceptional combination of mechanical innovation, traditional craftsmanship, and unmistakable German design.
