Eleven years of research and development. The assembly of no fewer than 935 parts. The filing of two patents. The development of an acoustic resonance cage producing an extremely pure sound. The incorporation of 11 security functions ensuring maximum peace of mind…These few elements alone give an idea of the magnitude of the almost gargantuan task of creating the first Greubel Forsey Grande Sonnerie.
