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. The synodic period equals 29 days, 12 hours, 44 minutes and 2.9 seconds which corresponds to 2’551’442.9 seconds.

Once correctly set, this high-precision moon phase will only require adjustment once every 122 years by a single push on the corrector! Scientists such as Isaac Newton or George Graham have made major discoveries as they realized that combining astronomy and time keeping would lead to remarkable advancement.

The main difficulty of the watch lies in the delicate and complex flying Tourbillon. It challenges Newton’s law of gravitation and also pays tribute to his remarkable findings. The Geo.Graham tourbillon rotates on a ball bearing to substitute rolling for sliding friction.
