Greubel Forsey

History Of Brand

GREUBEL FORSEY – Inventors Inventing Inventions Greubel Forsey is a very exclusive, ultra high-end watch brand founded by inventor watchmakers Robert Greubel (French) and Stephen Forsey (English) in 2004. With their comprehensive state-of-the-art research, testing and production atelier in La Chaux-de-Fonds, Switzerland, Greubel Forsey are able to use their EWT (Experimental Watch Technology) platform to turn fundamental ideas and inventions into sublimely finished and highly original complicated timepieces. These timepieces represent the very pinnacle of fine Swiss watchmaking and they advance horological knowledge and precision. Greubel Forsey’s first invention, the Double Tourbillon 30° (DT30°), was specifically intended to make the tourbillon, originally developed for use in a pocket watch, more effective in a wristwatch. It features an interior tourbillon carriage, inclined at 30° and revolving every 60 seconds, inside an exterior tourbillon carriage revolving every four minutes – a configuration offering superior timekeeping performance in all wristwatch positions. The second invention, the Quadruple Tourbillon a Differentiel Spherique (QDT), was created to both explore and push the very limits of using multiple tourbillons to improve timekeeping. Four asynchronous tourbillons, arranged in two double tourbillon systems linked by a spherical differential, ensure this invention’s extremely high precision. The Tourbillon 24 Secondes Incline (T24Si) is Greubel Forsey’s third invention and it features a single ultra-light inclined tourbillon cage which undergoes rapidly changing positions with a high angular velocity. Avional was used for the pillars of the cage and titanium for the carriage bridges to minimize mass and inertia while retaining maximum strength. Fundamental research in the EWT pipeline includes a Binomial mono-material balance and spring system and a Differentiel d’Egalite constant force device. All Greubel Forsey’s timepieces feature: highly original inventions developed to improve timekeeping precision; movement finishing taken to an extreme level of the art and craft; and movement/case architecture that provides maximum visual access to the intricate wonders within.
