few quantitative elements give some idea of the scale of this undertaking: 11
years of research and development, 935 components assembled inside a case that
measures 43.5 mm in diameter and 16.13 mm high, 11 security functions and two
patents for a timepiece that offers grande and petite sonneries on cathedral
the timekeeping function, completes the picture. Note that the striking mechanism
is automatically wound by rotor whereas the timekeeping mechanism is manually
wound. This is the most complex watch ever by Greubel Forsey, hence between three
and five only will be made each year.
