Introducing A. Lange & Söhne 1815 (ref. 421.048), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in platinum and measuring 41.9 mm in diameter, with a thickness of 15.8 mm, defined by a round silhouette. The caseback is hinged, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a blue tone, executed in enamel, framed by arabic numerals hour markers, and alpha hands. At its heart beats a proven engine: the L101.1 caliber. Released in a constrained run, appealing to focused collectors. Introduced in 2017. 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.
