Description

Between Heaven and Earth

The Perpetual Moon 38 Red Gold is unveiled here in a “Cliff Grey” limited edition, an interpretation of the bewitching full moon in a starry sky. Limited to just 28 pieces, this model captures the elegance of a warm sunlit grey, where subtle textures and deep nuances blend for a unique visual experience.

With its sophisticated grey “cliff grey” dial, this edition embodies the perfect contrast between the rocky cliff and the clarity of the moon, bathed in the midnight blue of a matte sky. The finely polished 38mm red gold (5N) case frames this celestial mineral universe, offering natural elegance under the soft, mysterious light of the moon.

Precision at the heart of Perpetual Moon

Equipped with the A&S1612 caliber, specially designed for this model, the Perpetual Moon 38 Red Gold “Cliff Grey” features an impressively precise moon phase, capable of remaining true to the lunar cycle for 122 years without adjustment. This manual movement, with a 90-hour autonomy, is the smallest in the Arnold & Son collection, but shares the same standards of horological excellence.

A Majestic Moon

Under a generous cut-out occupying the upper half of the dial, the mother-of-pearl moon illuminates the dark sky, staging the star’s cosmic dance between 10 and 2 o’clock. Dressed in luminescent material, it illuminates this celestial tableau, surrounded by the constellations of Cassiopeia and the Big Dipper.

Arnold & Son, true to its reputation for precision watchmaking, offers with this “Cliff Grey” edition a collector’s item where every detail, from color to texture, tells the story of a fragment of night.
