Experience the craft of A. Lange & Söhne in the 1815 (ref. 221.025), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in platinum and measuring 35.9 mm in diameter, with a thickness of 7.9 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a silver tone, executed in silver, framed by arabic numerals hour markers, and alpha hands. At its heart beats a proven engine: the L942.1 caliber. Introduced in 1997. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
