Robert Greubel grew up in Alsace, France. He began his horological career somewhat precociously by observing and working with his watchmaker father in the family shop, 'Greubel Horlogerie'.
In 1987, after studying complications, he moved to Switzerland to join IWC where he worked on their Grand Complication project. In 1990 Robert joined Renaud & Papi as a prototypist working in complicated watchmaking, and rose to joint managing director and partner of the firm.
He left in 1999 to work independently and, in 2001, co-founded Complitime with Stephen Forsey, to develop and craft complicated movements for prestigious brands.
In 2004 he co-founded 'Greubel Forsey' with Stephen Forsey.
