This Tourbillon Perpetual Calendar* is a highly complicated time piece that marked the introduction of a tourbillon with an automatic movement into the A. Lange & Söhne catalogue, and their first use of the instant-jump calendar indication. Only 100 pieces were made in platinum. The watch marks a fascinating point in the history of modern Lange watches.


The name Lange has been tied to watchmaking and the Saxony area of Germany for centuries. In the 1800s, Ferdinand Aldoph Lange – which is where the “A” in A. Lange & Söhne comes from – began his watchmaking journey under the tutelage of master watchmaker, Johann Christian Friedrich Gutkaes. Passed from father to son, the Lange name flourished, before encountering considerable obstacles during 20th century.

In 1990, the brand was resuscitated by Walter, the great-grandson of Ferdinand Adolph Lange, and watch industry veteran Günter Blümlein. A Nuremberg native, Blümlein grew up in post-war Germany, and had previously overseen the resurgence of IWC and Jaeger-LeCoultre. This started the four-year journey that Lange and Blümlein would go on with their small team to bring the company back from the ashes, with the release of their first four models on 25th October 1994.
