Double Tourbillon 30°
Greubel Forsey’s first-ever watch and the invention that founded the brand: a 30°-inclined tourbillon cage nested inside a second, slower-rotating cage, patented in 2004. The line closed in 2010 with the 22-piece Édition Historique (11 red gold, 11 platinum), an anthracite-dialled retrospective on the original design. Every later Greubel Forsey inclined-tourbillon watch descends from this architecture.
