Discover A. Lange & Söhne's precision with the Lange 1 (ref. 112.021), a contemporary classic shaped by careful watchmaking know-how.

At its heart beats a proven engine: the L901.1 caliber. Issued as a limited edition, appealing to focused collectors. First released in 19982001. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry.
