Arnold & Son is charting lunar territory once again with the Perpetual Moon 41.5 Red Gold Cliff Grey Edition, presenting a poetic celebration of celestial precision, rugged British heritage, and haute horlogerie. This model is showcasing a striking 41.5 mm case in 18k red gold, with a slim 11.3 mm profile and water resistance rated at 30 m, making it both elegant and wearable.
The dial is capturing attention with its “Stellar Rays” finish in a distinctive Cliff Grey hue—an homage to the weathered cliffs of Cornwall, the birthplace of marine chronometer pioneer John Arnold. The flinqué pattern is hand-engraved at variable depths, then treated with PVD and layered lacquer, creating a dynamic play of light and shadow. Embedded within the upper half is a 29 mm moon phase indicator featuring a mother-of-pearl moon disc coated with Super-LumiNova and hand-painted shadows. It is set against a textured midnight‑blue PVD sky with luminescent constellations, including Ursa Major and Cassiopeia—key navigational markers for mariners.
The watch is powered by a hand-wound A\&S1512 calibre, developed in-house, featuring dual barrels that ensure a remarkable 90‑hour power reserve and impressive lunar accuracy—only deviating by one day every 122 years. It operates at 21,600 vph (3 Hz) and is designed to be refined yet functional. A secondary moon-phase display on the caseback allows quick and precise adjustments.
Turning the case over, the sapphire exhibition back is revealing a meticulously finished movement. It is showcasing Geneva stripes, beveled bridges, blued screws, and polished anglage—all executed at Arnold & Son’s La Chaux-de-Fonds manufacture. The combination of technical performance and artisanal craftsmanship is placing the model firmly within the realm of high-end watchmaking.
The warm grey alligator strap is complementing the case, secured with a matching red gold pin buckle. The overall aesthetic is balancing lunar poetry, mechanical excellence, and sophistication, resulting in a highly collectible timepiece.
Limited to 28 numbered pieces, the Perpetual Moon Cliff Grey Edition is ideal for collectors drawn to romantic complications, historical resonance, and understated luxury.
In summary, Arnold & Son is presenting a watch that is evoking Cornwall’s dramatic coastline, astronomical tradition, and mechanical finesse in a single red gold creation. It is combining artisanal finishes, rare complications, and narrative depth—offering a moon-phase watch that reads as much like art as it does timekeeping hardware.
