The A. Lange & Söhne 1815 Annual Calendar (Ref. 238.026) is a stunning tribute to the brand’s founder, Ferdinand Adolph Lange, born in 1815. Crafted in elegant 18K white gold, the 40mm case features a refined silver-white dial with contrasting blue hands and black Arabic numerals, enhanced by a railway minute track and gold-toned subsidiary displays. At 6 o’clock, a highly precise moon phase complication stands out, boasting an accuracy of just one day’s deviation every 122.6 years—a testament to Lange’s engineering excellence.
Powering this timepiece is the manual-winding L051.3 movement, a masterpiece of German watchmaking. The movement showcases traditional Glashütte craftsmanship, including a ¾ German silver mainplate, hand-engraved balance cock, and gold chatons. The swan-neck fine adjustment ensures exceptional timekeeping, while the 72-hour power reserve offers practicality. Every detail, from the satin-brushed case sides to the fluted crown engraved with the Lange logo, reflects the brand’s dedication to precision and aesthetics.
Complete with a black crocodile leather strap and accompanied by its original box and 2018 warranty papers, this excellent condition (90%) timepiece represents a rare opportunity to own one of A. Lange & Söhne’s most sophisticated annual calendars. Combining historical inspiration with cutting-edge mechanics, the 1815 Annual Calendar is a true collector’s watch—blending elegance, functionality, and unparalleled craftsmanship.
