The exclusive mechanical timepieces by A. Lange & Söhne are crafted from precious materials with the utmost of artisanal skill and only in small editions. They are guardians of a horological culture that is handed down from generation to generation and that began in 1845 with the foundation of the Lange watch manufactory by Ferdinand A. Lange in Glashütte, Saxony. His ambition to define benchmarks with timepieces of the manufactory is still reflected in every single Lange watch.
