From A. Lange & Söhne, presenting the Lange 1 (ref. 115.321), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in yellow gold and measuring 41.9 mm in diameter, with a thickness of 10 mm, defined by a round silhouette. At a glance, the dial balances texture and clarity: a champagne tone. At its heart beats a proven engine: the L901.2 caliber. Initial production year: 20072008. 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.
