The Lange 1 137.038, seen from the bench

The Lange 1 was introduced in 1994 as the first model of the revival of A. Lange & Söhne after German reunification. It is equipped with the in-house caliber L095.1 manual-winding movement with a 72-hour power reserve, featuring a large date and offset small seconds. Reference 137.038 features the characteristic asymmetric dial with the distinctive layout of the Saxon brand.
