A. Lange & Söhne 1815 Annual Calendar 238.026E White Gold Silver Dial Moon Phase

The A. Lange & Söhne 1815 Annual Calendar ref. 238.026 blends a traditionally styled dress-watch case with a serious calendar complication in white gold. At 40mm across and finished in 18 k white gold, it features a silver-toned dial crafted from solid silver and retains the clean, classical design language of the 1815 line.

The watch offers an annual calendar with displays for the day, date and month arranged in classic sub-dials, and a moon-phase indication calculated to reach 122.6-year accuracy before requiring adjustment. Paired with a hand-wound movement visible through a sapphire caseback and mounted on a black alligator strap, the 238.026 delivers refined execution, mechanical depth and understated elegance—ideal for the collector who values craftsmanship, material quality and horological significance in equal measure.

*This watch has a 2021 service document from A. Lange & Söhne.
