A Fresh Perspective on an Iconic Lunar Display: The "Colours of the Moon" Collection

For over a decade, Arnold & Son's Perpetual Moon series has distinguished itself by making the lunar cycle a central element of its design. The brand's deep fascination with astronomy is evident in the numerous iterations of this model. Now, the company revisits this signature design with three exclusive limited editions, collectively known as the "Colours of the Moon."

Inspired by the Night Sky's Rare Occurrences: Blue, Golden, and Red Moon Editions

The latest Perpetual Moon 41.5 Steel "Colours of the Moon" collection comprises three unique timepieces, each inspired by infrequent lunar events. The Blue Moon edition evokes the rare occurrence of a second full moon within a single season and the subtle blue tones sometimes cast by atmospheric particles. The Golden Moon variant captures the warm, amber glow of the moon as it hangs low on the horizon. Finally, the Red Moon model pays homage to the distinctive reddish tint observed during total lunar eclipses, often referred to as Blood Moons.

Robust Elegance: The Stainless Steel Case Design

In a notable departure from previous collections that often featured precious metals, Arnold & Son has opted for a resilient stainless steel case for these new editions. Measuring 41.5mm in diameter and 11.67mm in thickness, the polished case strikes a balance between versatility and contemporary style. This choice allows the intricate dial work to take center stage, while the watch's elegant proportions and slender profile ensure comfortable wear for everyday use. A domed sapphire crystal with anti-reflective coating protects the dial, and a sapphire caseback reveals the inner workings of the movement. The watch offers a water resistance of 30 meters.

A Celestial Canvas: The Dial's Exquisite Astronomical Depictions

A hallmark of the Perpetual Moon remains its expansive moon-phase display, which dominates the upper half of the dial. The moon itself is meticulously crafted from colored mother-of-pearl and features Super-LumiNova beneath the disc, allowing it to emit a soft, ethereal glow against the darkened sky in low-light conditions. The dial, along with the surrounding night sky, is made from mother-of-pearl, treated with a controlled Physical Vapour Deposition process. This treatment allows for black, blue, or green variations, depending on the model, while preserving the natural iridescence and depth of the organic material, enriching it with more vibrant and saturated hues. Completing this celestial tableau are hand-painted representations of the Cassiopeia and Ursa Major constellations, also rendered in luminescent material.

Precision and Craftsmanship: The In-House Calibre A&S1512 Movement

Consistent with earlier models in the series, the new "Colours of the Moon" collection is powered by Arnold & Son's in-house calibre A&S1512. This manual-winding movement boasts an impressive 90-hour power reserve and operates at a frequency of 21,600 vibrations per hour. The movement is adorned with radiating Côtes de Genève, polished bevels, circular graining, and blued screws, showcasing the brand's commitment to traditional finishing standards. The reverse side of the movement also incorporates a secondary moon-phase indicator, facilitating precise adjustment of the complication.

Unparalleled Lunar Accuracy and Exclusivity: Limited Editions

As with previous Perpetual Moon timepieces, the moon-phase mechanism within these new models is engineered for extraordinary accuracy, requiring correction only after an extended period of continuous operation. Each version in the "Colours of the Moon" collection is paired with a matching alligator leather strap and is produced in a highly limited series of just 18 pieces per variant. These exclusive timepieces are priced at CHF 21,100 (including VAT), emphasizing their rarity and fine craftsmanship.
