Perpetual Moon Gold (38mm) is dedicated to the Earth’s only permanent natural satellite. Arnold & Son has incorporated its new astronomical moon-phase caliber into an ultra-slim 38mm rose-gold case. This indication appears in the aperture of a shimmering blue mother-of-pearl dial. A sumptuous diamond setting illuminates the hour-markers, crown, lugs, and bezel. Glittering by day, scintillating by night, Perpetual Moon Gold (38mm) makes radiance its hallmark.

Everything follows on from the spirit of this complication. Beneath the delicately blue-tinged mother-of-pearl dial with an openworked upper section, a large sky disc, also in mother-of-pearl, bears a white moon adorned with Super-LumiNova and hand-painted shadows. Nearby, the Ursa Major and Cassiopeia constellations complete the scene.

Perpetual Moon Gold (38mm) thus presents two faces. The first is the gem-set gold case and its mother-of-pearl dial evoking daytime. The other glows with a cold blue light to represent the night, when the stars painted with luminescent material shine and when the moonlight truly comes into its own.
