The Lange 1 101.031, seen from the bench

The A. Lange & Söhne Lange 1 ref. 101.031 is a 38.5 mm pink gold watch that marked the return of Saxon watchmaking to the world stage in 1994. It features the iconic asymmetrical dial with off-centre hours/minutes, large date at 1:30, small seconds at 9, and power reserve indicator. The manually wound calibre L901.0, entirely developed and assembled in Glashütte, powers hours, minutes, small seconds, large date display, and power reserve. The 20 mm lug width accommodates standard straps with straight endings, not curved ones, for proper fit on this classic gentleman's watch.
