White and green
Measuring 38 mm in diameter and 10.44 mm thick, the case of Perpetual Moon 38 Red Gold is brought to life from a block of red gold (5N). Its bezel, four lugs and crown are polished, shining under the cold light of the moon. The blue aventurine dial, constellated with metallic particles, blends into a celestial vault sculpted from the same glass.

A 38 mm picture of precision
Perpetual Moon 38 Red Gold transposes the watchmaking requirements that have always guided Arnold & Son into its slender case. The Arnold & Son Swiss manufacture has designed an entirely new calibre, the smallest in its collection, and dedicated it to Perpetual Moon 38.
At 30 mm, the A&S1612 calibre has been sized to fit the diameter of the case. The hand-wound movement continues Arnold & Son’s tradition of calibres with long power reserves, reaching 90 hours.
Waxing moon, waning moon
The star complication of the A&S1612 calibre is its moon phase. Perpetual Moon 38 showcases a large moon disc. The different crescents occupy the large aperture between 10 and 2 o’clock, with the form of their cut-out faithfully recreating the appearance of the moon.
True to its tradition of precision watchmaking, Arnold & Son has given this moon phase an accuracy of 122 years. Continuously rising, it will take more than a century for this moon to lag one day behind the real one in our skies.
