The 19th century was an era forged by numerous adventurers, explorers, and discoverers. Countless expeditions embarked on a quest for new scientific insights. Aviation pioneers conquered the air with their flying machines. They needed accurate, portable timepieces called observation watches. “A. Lange & Söhne” equipped many of these visionaries with dependable time measuring instruments. Reviving the tradition of these scientific observation watches, Lange today again crafts a fine watch of this type for the wrist: the RICHARD LANGE.
