Meet A. Lange & Söhne Lange 1 (ref. 320.040), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in platinum and measuring 39.5 mm in diameter, with a thickness of 10.4 mm, defined by a round silhouette. The caseback is open, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a silver tone with guilloche finish, executed in silver, framed by mixed hour markers, and alpha hands. At its heart beats a proven engine: the L021.1 caliber. Produced in limited numbers, appealing to focused collectors. Introduced in 2018. 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.
