Geo.Graham The Moon is a history making celestial
representation. Its name pays tribute to the GRAHAM tradition and
heritage descending from George Graham who engraved his signature
on each of his exclusive creations since 1695.
It is a truly unique watch that combines a flying tourbillon
with a high-precision retrograde moon-phase perpetual function, the
cycle being calculated on the Moon's exact synodic period for a
duration of 122 years. At the end of each synodic period, the
retrograde mechanism ensures that the Moon jumps back to the
beginning of a new moon-phase cycle.
Big in appearance, our Moon only weights 0.07 grams and is
hand-painted by local craftsmen in Le Locle. To avoid any damage on
the lunar disc and attenuate the retrograde fall, a double absorber
system has been developed exclusively for GRAHAM by Christophe
Claret in Locle.
