Arnold & Son Watch Perpetual Moon 38 Rose Gold 1GLMR.U01A.C206A. 

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 38 Gold 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.
