The Lange 1 110.031, seen from the bench

The Lange 1 was introduced in 1994 as the first model of the revived A. Lange & Söhne after German reunification. It features the in-house manufactured caliber L901.0 hand-wound movement with hours, minutes, small seconds, big date and power reserve indication. The reference 110.031 presents the characteristic asymmetric dial layout with the time display elements arranged in a decentralized manner.
