The Lange 1 137.033, seen from the bench

The Lange 1 was introduced in 1994 as the first model of the renaissance of A. Lange & Söhne after the German reunification. It mounts the in-house L095.1 manual-winding caliber with large date, small seconds and power reserve. The dial features the characteristic asymmetric layout with large date at 1 o'clock and small seconds at 5 o'clock.
