The dial on the new Arnold & Son Perpetual Moon presents a unique finish known as Stellar Rays, its aesthetic obtained through skilfully irregular engraving.

Several depths and widths of rays coexist and follow on from one another, creating their own rhythm, each generating a fluctuating interplay of light and a depth obtained by applying several layers of transparent lacquer.

This unique effect is employed in two forms. Perpetual Moon 41.5 Red Gold is combined with a dense, deep blue adorned with gold edging on the moon aperture, together with golden hands and hour markers.
