Lange can be credited with many horological innovations, including replacing the rotating arc with something called a lathe, still in use today. Lange claims he was also responsible for the development of the jumping seconds, the three-quarter plate, early work in keyless winding, and more. Tomorrow, February 18th, would be Mr. Lange’s 200th birthday, and in celebration, A. Lange & Söhne has introduced a gorgeous and elegant new watch.
