The reference 221.021 belongs to the first-generation 1815 Up/Down, produced from 1997 to 2008. Its design draws from an 1879 Lange patent for a mechanism indicating whether the movement is wound (AUF) or unwound (AB). This historic feature is elegantly integrated into a perfectly symmetrical, layered silver dial, renowned for its legibility and depth.
Powering the watch is the hand-finished calibre L942.1. Crafted from untreated German silver, it develops a unique patina over time and is adorned with a hand-engraved balance cock, showcasing Lange’s signature artisanal craftsmanship. This model is a testament to the brand’s technical heritage and aesthetic refinement.
