About the Double Tourbillon 30° family
The Double Tourbillon 30°, launched in 2004, was Greubel Forsey's first watch and its first fundamental invention. It has a fast-rotating tourbillon inclined at 30 degrees, mounted inside a second, slower tourbillon, an arrangement meant to average out the effects of gravity in every position.
The catalog lists several versions, including the Technique, Technique Black, Secret, Asymétrique and Edition Historique. Each was made in small numbers, so the certificate, full set and service history from the brand are essential.
