The Richard Lange Tourbillon is a remarkable demonstration of A. Lange & Söhne’s pursuit of chronometric excellence. Inspired by precision regulators once used in scientific laboratories and observatories, this exceptional timepiece combines a classical tourbillon with one of the manufacture’s most celebrated innovations—a stop-seconds mechanism that allows the rotating tourbillon cage to halt instantly for precise time setting. This ingenious solution transformed one of watchmaking’s oldest complications into an instrument of true practical precision.

Its manually wound manufacture calibre is assembled and regulated entirely by hand in Glashütte before undergoing a second complete assembly following decoration. Untreated German silver bridges, polished steel components, gold chatons, thermally blued screws and an individually hand-engraved balance cock reflect the extraordinary finishing standards that distinguish every A. Lange & Söhne movement. Produced in extremely limited quantities, the Richard Lange Tourbillon stands among the finest examples of contemporary German haute horlogerie.
