A PLAY OF LIGHT ON THE CLIFFS
The new Perpetual Moon 41.5 Cliff Grey Edition features a dial in the same shade as the cliffs of Cornwall: a homage to the county of birth of Arnold & Son’s founder and the port of departure for His Majesty’s ships, equipped with marine chronometers designed by John Arnold. The collection’s signature immense moon, standing as a symbol for high-sea navigation, crosses a night sky glittering with the constellations of Ursa Major and Cassiopeia. A limited edition of 28 pieces in red gold, Perpetual Moon 41.5 Cliff Grey is brought to life by glistening hues and Arnold & Son’s watchmaking soul.

Ever-shifting
The dial of this Perpetual Moon 41.5 Red Gold series features the Stellar Rays finish, an exclusive Arnold & Son signature. It showcases a unique aesthetic. Various depths and widths of rays follow on from one another, creating a distinctive rhythm. Their sequence produces a fluctuating play of light, accentuated by the depth created by successive layers of transparent lacquer. In this new limited edition of 28 pieces, the Cliff Grey shade is a reference to the British coast and its cliffs bathed in a hazy light.

Nocturnal
The moon appears in the sky. Depicted realistically with hand-painted shadows, the earth’s natural satellite is rendered in mother-of-pearl overlaid with Super-LumiNova. It sits against a grained sky with a blue PVD treatment, adding to its evocative power. True to the custom of the Perpetual Moon collection, the moon is surrounded by the constellations of Ursa Major and Cassiopeia, both hand-painted and overlaid with luminescent material. The choice of these star patterns is a direct allusion to the history of marine chronometer-maker John Arnold
Accuracy of light
On the case back, a secondary indicator allows the moon phase to be adjusted quickly and precisely. The hand-wound calibre that powers it, reference A&S1512, can track the development of its segments with exceptional precision. The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. Arnold & Son has succeeded in representing it in such a way that it would take 122 years for this movement, if regularly wound, to accumulate a day’s difference between its display and celestial reality.
Like all Arnold & Son movements, the A&S1512 calibre has been entirely developed, manufactured, decorated, assembled, adjusted and cased at the Manufacture in La Chaux-de-Fonds. The calibre features two barrels and an oscillation frequency of 3 Hz, providing a power reserve of 90 hours.
