The Perpetual Moon 41.5 Platinum Fern Green Edition by Arnold & Son delivers precise lunar tracking with a distinct design, now in green. This limited-edition watch combines mechanical innovation and artistic craftsmanship, making it another collector’s piece. This time limited to 28 pieces, whereas the 2023 Arnold & Son Perpetual Moon 41.5 Platinum Celestial Blue was limited to 38 pieces. The Fern Green is the same except for the color.
So, this green Perpetual Moon features a 41.5-millimeter platinum case as well, with a depth of 11.3 millimeters. Its fern green dial, finished with a “Stellar Rays” texture, offers a shimmering effect achieved through layered engraving and lacquer.
Mother-of-pearl Moon
Here the dial’s mother-of-pearl moon sits against a midnight-blue sky enhanced with super-luminova. Luminescent details of the Ursa Major and Cassiopeia constellations frame the moon. These constellations are an allusion to the history of marine chronometer-maker John Arnold. Together these form the first moon phase display. Furthermore, hours and minutes on the front.
On the back of the sapphire crystal case is a secondary moon phase display that aids with quick adjustments. The design ensures easy readability, with clear divisions between celestial and terrestrial elements.

Movement and Power Reserve
The manual-winding Arnold & Son caliber A&S1512 powers this watch. Developed entirely in-house, it boasts a power reserve of 90 hours, supported by twin barrels. The movement achieves lunar precision, requiring over 122 years to accumulate a 24-hour discrepancy.
Decorations on the A&S1512 include rhodium-plated radiating côtes de Genève stripes, chamfered and polished bridges, and blued screws with polished heads. The caliber’s development reflects Arnold & Son’s commitment to technical and aesthetic excellence.

The strap is made of Cornwall green alligator leather, paired with a crimson-purple alligator lining. A platinum pin buckle secures the watch, complementing its case material and ensuring durability.
This Perpetual Moon 41.5 Platinum Fern Green Edition retails at 46,700 Swiss francs, just above 50k in dollars or euros. Comparable watches, like models from A. Lange & Söhne, Christiaan van der Klaauw, or Jaeger-LeCoultre also offer high-end moon phase complications in a comparable price range.
