The Lange 1 181.063, seen from the bench

The Lange 1 181.063 is a 36.8 mm pink gold watch from the 30th Anniversary collection, featuring the iconic asymmetrical dial with large hour-minute display on the left and small seconds on the lower right. It houses the L121.1 calibre, a German-made manual-wind movement assembled in Glashütte with a three-quarter German silver plate. The 20 mm lug width accommodates the watch's balanced proportions and elegant dial architecture.
