Today, we bring you a new watch that left many in awe at the SIHH 2016 Salon International de la Haute Horlogerie. The new Greubel Forsey GF01 Signature 1 Unique Edition was presented as the point of entry watch into the Greubel Forsey brand. This watch not only represents a new era for Greubel Forsey, but it also revives a popular concept dating back to the 18th and 19th centuries known as 'subscription watch' and made popular by Abraham-Louis Breguet.
