Introducing A. Lange & Söhne Lange 1 (ref. 813.047), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in pink gold and measuring 36.1 mm in diameter, with a thickness of 10 mm, defined by a round silhouette, paired with a gem-set bezel. The caseback is open, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a white tone, executed in mother of pearl, framed by mixed hour markers, and alpha hands. At its heart beats a proven engine: the L901.4 caliber. Initial production year: 2014. 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.
