Introducing A. Lange & Söhne 1815 (ref. 231.031), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in pink gold and measuring 35.9 mm in diameter, with a thickness of 7.45 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire. Visually, the face is where character emerges: a black tone, executed in silver, framed by mixed hour markers, and alpha hands. Mechanically, the watch prioritizes accuracy: the L943.1 caliber. Released in a constrained run, appealing to focused collectors. Introduced in 1999. 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.
