The Lange 1 is one of four models presented by A. Lange & Söhne as the first collection revived by Walter Lange. This model, which combines the tradition of manufacture and innovation, has become synonymous with Lange watchmaking. The Lange 1 Family has added a new page to its history with groundbreaking new technologies such as off-center dial design and outsize date. And "Lange 1" is a monumental model as "Lange revival" released in 1994. 25 years from announcement. It is still the face of Lange & Söhne, and was a big topic in the 25th anniversary model in 2019. It is also a watch that values "History and Tradition" based on the motif of the five-minute clock installed in the "Dresden Opera House" created by Adolf Lange with his teacher Gutkes.
