The Lange 1 101.050, seen from the bench

The Lange 1 was introduced in 1994 as the first model of the revived A. Lange & Söhne manufacture. It is equipped with the in-house caliber L901.0 manual-winding movement with hour, minute, small seconds, big date and power reserve displays. The reference 101.050 features the characteristic asymmetric dial layout with the big date at 1 o'clock and power reserve indicator at 2 o'clock.
