First as the CompliTime atelier in 2001, and then as the fully formed Greubel Forsey brand, Greubel Forsey has redefined the concept of fine watchmaking, at least the one known until then. It was at Baselworld 2004 when Stephen Forsey and Robert Greubel presented their watchmaking prowess, with their inventive spirit, high-end artistry and love for accuracy, embedded in each of their handmade timepieces. As proof of concept, their 1st Invention was the Double Tourbillon 30°, with a patented regulating system specifically adapted for the wristwatch. From 2005, they would present six more Inventions that represent their quest for ultimate precision.
