Arnold & Son Perpetual Moon 38 Red Gold Moonlight

Arnold & Son is expanding its moon-phase collection with the new Perpetual Moon 38 model in red gold (5N) featuring a shimmering blue mother-of-pearl dial.

The Arnold & Son Perpetual Moon 38 Gold Moonlight watch is adorned with 138 diamonds for a total of ~2.61 carats. This timepiece is powered by a finely crafted manual-winding calibre.

Under the delicately blue-tinged mother-of-pearl dial with an open-worked 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.

For the Perpetual Moon 38 Gold watch, Arnold & Son has created an entirely new women’s calibre, the smallest in its collection.

At 29.4 mm, the A&S1612 movement was designed to fit the new 38 mm diameter case that is just 10.44 mm thick. This manually wound movement has a power reserve of 90 hours.

Arnold & Son draws on its iconic complication by presenting a large moon disc on this A&S1612 calibre. The various crescents displayed between 10 o’clock and 2 o’clock faithfully recreate the appearance of the Earth’s satellite. This moon-phase complication will remain accurate for 122 years.
