From A. Lange & Söhne, presenting the 1815 (ref. 303.021), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in yellow gold and measuring 37 mm in diameter, with a thickness of 8.2 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 L921.2 caliber. First released in 2004. 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.
