Perpetual Moon 41.5 Platinum, Fern Green edition - Clear Skies

NOVEMBER 15 2024    |    Novelties

Moonlight illuminates a botanical green dial. The “Fern Green” version of Perpetual Moon 41.5 borrows the cool tones of the moon. The paleness of the platinum, the freshness of the fern green, and the midnight blue of the sky create an original flow of colours.

Maturity, diversity and mechanical exclusivity: the Perpetual Moon collection is constantly being enriched with new creations, consistently reaffirming the watchmaking and artistic talents of Arnold & Son. Following two other editions, one with salmon pink accents and another in sky blue, Perpetual Moon 41.5 Platinum is now available in this limited fern green version of 28 timepieces.

Its hue is inspired by the unique colour of the fern, an undergrowth plant found in abundance in the English gardens of Cornwall, the county where John Arnold was born.

 

Shimmering
The “Stellar Rays” finish enlivens the dial with a sophisticated shimmer. This aesthetic is achieved through cleverly irregular engraving. Various depths and widths of rays coexist and follow on from one another, creating a unique rhythm. Their succession produces a fluctuating play of light, accentuated by the depth created by several layers of transparent lacquer.

Realistically depicted and set against a grained sky with a midnight blue PVD treatment, the large white mother-of-pearl moon is also overlaid with Super-LumiNova. Invisible by day, this added colour gives it a whole new face by night.

Compass
Following in the tradition of the Perpetual Moon collection, the moon is surrounded by Ursa Major and Cassiopeia, both hand-painted and overlaid with luminescent material. The choice of these star patterns is an allusion to the history of marine chronometer-maker John Arnold.

These two constellations have always served as landmarks in the night sky. Halfway between the two easily identifiable groups is Polaris. Its position always shows the north and its elevation angle can be used to estimate the distance from the equator, i.e. the latitude. Before the invention of instruments to determine the longitude, it was the most reliable measure of a ship’s position at sea.

Accuracy
On the case back, a secondary display of the phases of the moon allows fast and accurate adjustment of the moon age. The manually-wound A&S1512 calibre that powers it is able to track its phases with exceptional accuracy. The total duration of a lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. Arnold & Son has approached this so closely that it would take 122 years for this movement, if constantly wound up, to accumulate a 24-hour discrepancy between the display and astronomical reality.

Like all Arnold & Son’s movements, the A&S1512 calibre was entirely developed, produced, decorated, assembled, adjusted and cased up at the manufacture in La Chaux-de-Fonds. This calibre uses two barrels and has an oscillation frequency of 3 Hz, giving a 90-hour power reserve.

Arnold & Son Unveils the Perpetual Moon 41.5 Steel "Colours of the Moon"

Arnold & Son has unveiled its new "Perpetual Moon 41.5 Steel Colours of the Moon" collection, a series of highly exclusive, limited-edition timepieces inspired by the changing celestial hues of Earth's natural satellite. Detailed in the official release document, "ENG_A&S PM 41.5 Steel Colours of the Moon.doc", the collection features three distinct versions—the Blue Moon, Golden Moon, and Red Moon—each celebrating a unique atmospheric or seasonal phenomenon that alters the Moon's appearance and has fascinated civilisations throughout history.

Reinterpreting the iconic Perpetual Moon collection, these new models introduce a 41.5 mm stainless-steel case that balances horological exclusivity with everyday versatility. In a watchmaking first, Arnold & Son has applied a pioneering Physical Vapour Deposition (PVD) treatment directly onto precious mother-of-pearl. This innovative process creates deep, shifting reflections across the dials and moon-phase skies, showcasing the natural organic layers of the material with patterns that recall the flowing grain of Damascus steel.

The astronomical precision of the moon phase is enhanced by Super-LumiNova hidden beneath the colored mother-of-pearl moon disc, accompanied by hand-painted luminescent constellations of Cassiopeia and Ursa Major—a poetic tribute to historical mariners who relied on them for navigation. Bringing this celestial mechanics to life is the in-house A&S1512 manual-winding calibre. This movement provides a generous 90-hour power reserve and displays meticulous luxury finishes, including radiating Côtes de Genève and a secondary moon-phase indicator, all visible through the sapphire crystal case back.

Each of the three references is paired with a matching hand-stitched alligator leather strap and secured with a stainless-steel pin buckle. To maintain their extreme exclusivity, production is strictly limited to just 18 pieces per version.

Tinkler 1958: Precision at a Quarter Turn

A faithful tribute to the original model, the Tinkler 1958 repeater celebrates Angelus’s rich heritage of striking watches. Driven by a self-winding quarter-repeater movement, this double limited edition, available in gold or steel, continues the tradition of measuring instruments that built the manufacture’s reputation. From its establishment in 1891, the name Angelus has been synonymous with the chiming of a bell, a legacy reinforced by one of the Maison's first patents for a silent strike governor in 1896. Since then, repeater mechanisms have remained at the heart of Angelus collections, even being adapted into Braille-repeating watches for blinded soldiers during the First World War.

Inspired by this glorious history, Angelus is reissuing one of its rarest and most refined models: the Tinkler, based on the original 1958 edition. In 1958, Angelus filed a patent for a striking wristwatch, which was immediately followed by the original Tinkler—a pioneer of water-resistant, self-winding quarter-repeater watches. The new 38-mm case charms with a decidedly 1950s aesthetic that is clean, understated, and elegant. At 9 o’clock, the crown is balanced by a pusher that activates the quarter repeater, serving as a functional and historical hallmark of this legendary model.

The Tinkler 1958 edition is driven by the new Angelus A600 calibre, a mechanical self-winding movement that beats at 4Hz and offers a 70-hour power reserve. On request, the pusher at 9 o’clock triggers a sequence where each hour is marked by a clear strike on the first gong, followed by a double strike on two gongs to signal each quarter hour. The movement's finishing demonstrates the watchmaker's extreme attention to detail, featuring a snail-finished main plate, palladium-plated bridges adorned with Côtes de Genève, and a tungsten sunburst oscillating weight.

This new release is part of the La Fabrique line, where Angelus continues its legacy as a maker of specialty watches designed for specific activities or professional uses. The Tinkler 1958 is limited to 15 pieces in 18-carat yellow gold and 25 pieces in stainless steel, each paired with an alligator flank leather strap—ink blue for the gold version and saddle brown for the steel. Combining a modernist-style numeral 12 with exclamation-shaped hour markers at the quarter positions, the watch serves as a modern embodiment of a daring yet functional tradition.

A New Pulse of Colour: Armin Strom Unveils the Mirrored Force Resonance Red

Armin Strom has masterfully fused its revolutionary resonance technology with a bold, contemporary aesthetic in the new Mirrored Force Resonance Red. Limited to just 15 pieces worldwide, this rare masterpiece introduces a striking off-centre guilloché dial in vibrant red. By pairing traditional hand-crafted artistry with the brand’s signature open-worked design, this timepiece breathes dynamic new energy into Armin Strom's celebrated dual-balance mechanism, creating a captivating dialogue between classic hand-finishing and cutting-edge mechanical architecture.

The brilliant red dial is hand-crafted on a traditional, manually operated rose engine lathe, engraving a radiating pattern that catches and plays with light in captivating reflections. Encircled by black azuré (蝸形紋) chapter rings and topped with faceted, floating index markers, the dial's layout creates a stark, three-dimensional contrast that maximizes both visual depth and legibility. Housed in a polished 43 mm stainless steel case, the movement's technical architecture is framed by anthracite-coated bridges and paired with a dark grey Alcantara strap—ensuring that the vibrant red dial and the synchronized dance of the resonance mechanism remain the undisputed center of attention.

At the heart of this technical marvel lies the in-house Calibre ARF21, a hand-wound movement that integrates two completely independent movements within a single calibre. Connected via Armin Strom's patented Resonance Clutch, the two opposing balance wheels transfer vibrations to enter and maintain a perfect state of harmonic resonance. This physical synchronization significantly improves chronometric stability and rate consistency over time. To let wearers witness this horological phenomenon in action, a pusher at 2 o'clock activates a flyback mechanism, resetting both independent seconds hands to zero simultaneously so their perfect synchrony can be monitored in real-time.

Every millimeter of the Mirrored Force Resonance Red showcases Armin Strom's uncompromising dedication to haute horology standards, featuring meticulous hand-polished bevels, perlage, circular graining, and mirror-black polished screws. On the reverse side, the main plate features technical inscriptions rendered in three-dimensional relief, rising directly from the metal's surface. As is tradition for the Swiss manufacture, each watch is assembled twice to guarantee absolute precision. For collectors seeking the pinnacle of independent Swiss watchmaking, this 15-piece limited edition represents a perfect harmony of mechanical science and artistic expression.

C BY ROMAIN GAUTHIER 39.5: BUILT FOR EVERYDAY ELEGANCE

Independent manufacture Romain Gauthier has unveiled its latest horological evolution with the release of the C by Romain Gauthier Titanium Edition 39.5. This new iteration introduces a highly anticipated, more compact 39.5 mm Grade 5 titanium case designed to sit effortlessly on a broader range of wrist sizes. Embodying the core philosophy of the collection, the timepiece is built for everyday wearability, blending high-end mechanics with a casual, modern design language that seamlessly integrates into daily life.

Enhancing this newfound versatility, the manufacture introduces its very first interchangeable rubber strap system alongside three expressive new colorways: vibrant blue, energetic orange, and subtle pink. These eye-catching color accents on the dial are matched with corresponding Super-LumiNova hues at night, offering a fresh, lifestyle-oriented aesthetic. The quick-release strap system allows wearers to effortlessly adapt the watch to any mood, outfit, or occasion, transitioning seamlessly between sporty casualness and discreet, refined elegance.

While the exterior boasts a contemporary, relaxed style, the heart of the watch remains deeply committed to haute horlogerie. The in-house manual-winding caliber is gloriously on show through the display back, showcasing finger bridges—historically typical of Romain Gauthier’s birthplace, the Vallée de Joux—reinterpreted with a modern "stepped" architecture. Each Grade 5 titanium bridge is meticulously finished by hand, featuring a highly original dimpled texture achieved through a special hand-engraving technique, set against a beautifully hand-frosted movement mainplate.

Technically astute, the timepiece is equipped with a clever stop-seconds mechanism that uses a snail cam—a nod to the brand’s acclaimed Logical One. Pulling out the crown stops the balance wheel, while pushing it back in prompts the snail cam to turn, delivering an active impulse to help the movement start beating again instantly. Offered as part of the brand's permanent, non-limited collection, the C by Romain Gauthier Titanium Edition 39.5 represents a masterful synthesis of superlative hand-finishing and modern, adaptable luxury.
