Experience the craft of A. Lange & Söhne in the Lange 1 (ref. 191.021), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in yellow gold and measuring 38.5 mm in diameter, with a thickness of 9.8 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire. Visually, the face is where character emerges: a champagne tone, framed by mixed hour markers, and alpha hands. Mechanically, the watch prioritizes accuracy: the L121.1 caliber. Introduced in 2015. The silhouette offers presence without excess, lending confidence in a range of situations. Finishing showcases disciplined attention to detail across facets, edges, and surfaces. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
