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.

Bringing celestial mechanics to life
To bring this celestial mechanism to life while ensuring everyday timekeeping, Arnold & Son has equipped the three Perpetual Moon “Colours of the Moon” limited editions with its in-house A&S1512 manual-winding calibre. With a diameter of 34 mm and a thickness of 5.35 mm, this movement offers a generous 90-hour power reserve when fully wound.
Luxury finishing
Visible through the sapphire crystal case back, the calibre demonstrates meticulous attention to detail in its finishing, from the 3 Hz regulating organ to the bridges adorned with radiating Côtes de Genève and hand-bevelled edges, as well as the perlage of the main plate and the snailing of the wheels. This opening also reveals blued screws with polished, chamfered heads and a secondary moon-phase display with graduated markings, allowing precise adjustment of the astronomical display visible on the dial side.
Classic styling
In keeping with their striking aesthetic character, the Perpetual Moon “Colours of the Moon” timepieces are paired with hand-stitched alligator leather straps in matching tones. They are fastened with traditional pin buckles in the same stainless steel as the case.
