Official description

Like all Arnold & Son creations, the new Perpetual Moon “Colours of the Moon” celebrates the art of watchmaking inspired by one of the Maison’s three principles – Astronomy, Chronometry and World Time – in a homage to its founder, John Arnold. With its “Colours of the Moon” series, Arnold & Son showcases astronomy. Presented in limited editions of 18 pieces each, these three steel versions introduce a world first in watchmaking: the use of mother-of-pearl coloured using a PVD process for both the dial and the moon phase sky. Dedicated to our natural satellite, they feature a mother-of-pearl moon-phase disc with remarkable astronomical precision. It is luminescent and crafted in three shades inspired by the changing hues of the Moon in certain seasons or under exceptional conditions.
