The Arnold & Son Perpetual Moon 41.5 Cliff Grey Edition presents a dial rendered in the distinctive hue of Cornwall's dramatic coastline, paying tribute to the birthplace of Arnold & Son's founder and the historic harbor from which Royal Navy vessels embarked, carrying marine chronometers crafted by John Arnold. The collection's distinctive oversized moon, serving as an emblem of oceanic navigation, traverses a star-filled firmament adorned with the constellations Ursa Major and Cassiopeia.
Things to Know About the Watch
This limited series of 28 timepieces in 18K 5N red gold brings the Perpetual Moon 41.5 Cliff Grey to life through luminous tones and Arnold & Son's horological essence. Arnold & Son, Switzerland's most quintessentially English manufacturer, continues its celestial and terrestrial journey. This Cliff Grey variant introduces a dial featuring a radiating Stellar Rays pattern, enhanced through layered variations in color and texture. Housed within a 41.5 mm diameter 18K 5N red gold case measuring 11.30 mm in height, this Perpetual Moon 41.5 prominently displays one of horology's most substantial moon representations.
The dial of this Perpetual Moon 41.5 Red Gold collection showcases the Stellar Rays finish, an exclusive Arnold & Son hallmark. It presents a distinctive visual character. Rays of varying depths and widths flow seamlessly into one another, establishing a captivating cadence. Their arrangement generates a shifting interplay of illumination, enhanced by the dimensionality achieved through multiple applications of transparent lacquer.
During low light conditions, the lunar disc emerges across the heavens. Portrayed with striking realism through hand-applied shadows, Earth's companion is crafted from mother-of-pearl enhanced with Super-LumiNova. It rests against a textured celestial backdrop featuring a blue PVD coating, amplifying its atmospheric presence. Following the Perpetual Moon collection's tradition, the moon is encircled by the star formations of Ursa Major and Cassiopeia, both hand-rendered and treated with luminous material. These stellar patterns directly reference the legacy of marine chronometer pioneer John Arnold.
The Movement
Powering this watch is the manual wound A&S1512 calibre with lunar phases. A complete lunar cycle spans 29 days, 12 hours, 44 minutes, and 2.8 seconds. Arnold & Son has achieved such extraordinary accuracy that this movement if continuously wound, would require 122 years to develop a full day's deviation between the displayed phase and actual astronomical conditions. The case back also features a secondary moon-phase indicator that enables precise and efficient adjustment of the lunar age. This movement underwent complete development, production, decoration, assembly, regulation, and casing exclusively at the Arnold & Son manufacture in La Chaux-de-Fonds. This calibre incorporates dual barrels and beats at a frequency of 21,600 vph delivering an impressive 90-hour power reserve.
The Arnold & Son Perpetual Moon 41.5 Cliff Grey Edition reference 1GLBR.N01A.C0246A is available in a limited edition of 28 pieces and delivered on a warm grey alligator leather strap with an 18K 5N red gold pin buckle.
