This is the untold story of how two rebellious master watchmakers, Robert Greubel and Stephen Forsey, learned their craft, met, established a brand, and in a few years created some of the most astonishingly beautiful and mechanically sophisticated timepieces ever made. Today they are recognized as the makers of the most uncompromising designs in the world. The two men met in early 1992 at Renaud et Papi, a hothouse of new watchmaking ideas in Le Locle in the Swiss Jura Mountains. They teamed up and launched Greubel Forsey in 2004 in La Chaux-de-Fonds, Switzerland, refusing to accept that everything had already been invented in watchmaking. Going against the grain, they focused their energy on uncompromising innovation and the most difficult elements of hand finishing, bringing back a level of excellence that would rival the eighteenth- and nineteenth-century masters. Greubel and Forsey are responsible for many inventions that have advanced watchmaking expertise to new levels as well as creating thirty unique and original calibres since 2004.
