The latest perpetual moon timepiece edition from Arnold & Son is stunning

Arnold & Son expands its collection with the launch of the Perpetual Moon 41.5 Platinum “celestial blue” timepiece, as different variations on the largest astronomical moon. Every part of this timepiece radiates lunar excellence, from the dial stamped with the House’s “Stellar Rays” decor to the moon disc in a grained sky and the navy-blue alligator-leather strap.

Delicacy

This edition showcases the latest characteristics of the Perpetual Moon collection, substantially redesigned to achieve greater refinement and subtlety. The lugs have been simplified and refined. Instead of the original cross shape, they now present a tauter form of plunging bars with beveled ends.

Moreover, they also form a single piece with the case middle, in terms of both their construction and appearance. After remaining at 42mm for a long time, the case of the timepiece has been slightly reduced to 41.5mm without altering the dial opening, giving a slimmer bezel instead.

Light

The dial is adorned with the “Stellar Rays” finish. Its aesthetic is obtained through skilfully irregular engraving. Various depths and widths of rays are successively combined to create a specific rhythm. Their sequence produces a fluctuating play of light, which is accentuated by the depth created by several layers of transparent lacquer.

Accuracy

On top of that, on the case back, a secondary indicator allows the moon phase to be adjusted quickly and precisely. The hand-wound caliber that powers it, reference A&S1512, is capable of tracking 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 also 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 for a far more stunning and sophisticated timepiece overall.

Like all Arnold & Son movements, the A&S1512 caliber has been entirely developed, manufactured, decorated, assembled, adjusted, and cased at the Manufacture in La Chaux-de-Fonds. The caliber features two barrels and an oscillating frequency of 3Hz, providing a power reserve of 90 hours.
