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.

Armin Strom Unveils the Mirrored Force Resonance Ice Blue – A Tribute to Precision and Craftsmanship

Armin Strom proudly presents the Mirrored Force Resonance Ice Blue, a limited edition timepiece that exemplifies the brand’s dedication to horological innovation and artisanal excellence. With only 15 pieces available worldwide, this release marks a bold evolution in the art of synchronized timekeeping.

The watch features a striking ice blue sunray guilloché dial, crafted using a traditional hand-operated rose engine lathe. Its off-center layout and radiant finish create a captivating play of light beneath the sapphire crystal, while beveled and polished indexes and hands add depth and movement to the design.

At the core of this timepiece is the manually wound Caliber ARF21, a technical breakthrough in resonance watchmaking. Armin Strom’s patented clutch system connects two balance wheels, allowing them to oscillate in opposite directions and synchronize for enhanced precision and stability. Twin seconds counters provide a visual representation of this resonance effect, and a pusher at 2 o’clock resets the counters, offering a clear demonstration of the mechanism’s accuracy.

The movement is hand-finished to haute horology standards, with Geneva stripes, perlage, and black-polished screws visible through the transparent case back. Each watch is assembled twice to ensure both mechanical integrity and flawless finishing.

Encased in a 43 mm stainless steel case and paired with a dark blue Alcantara strap, the Mirrored Force Resonance Ice Blue is a celebration of independent Swiss watchmaking and the science of movement.

Arnold & Son Unveils Perpetual Moon 41.5 Red Gold “Year of the Horse” – A Tribute to the Fire Horse

Mystical, untamed and dazzling, the Perpetual Moon 41.5 Red Gold “Year of the Horse” follows in the footsteps of Arnold & Son’s Chinese zodiac collections. In the year spanning 2026 and 2027, the Fire Horse will set the astrological tone for connoisseurs of watchmaking and métiers d’art. To celebrate this flamboyant sign, Arnold & Son presents a limited edition of eight pieces, housed in 41.5-mm red gold cases. And while the noble animal is ever alert, it is at night that the full extent of its fiery, mysterious and incandescent nature is revealed.

A horse rears on a hill top – a commanding silhouette carved out against a star-studded sky, surrounded by the sparks of a metaphorical fire. This is Arnold & Son’s interpretation of the Fire Horse, the sign that will succeed the Wood Snake on 17 February 2026. For the sixth consecutive year, Arnold & Son is back in the saddle, drawing on the full breadth of its artistic savoir-faire. Miniature painting, three-dimensional engraving, fine stonework and the refined finishing of an astronomical moon-phase calibre: the Perpetual Moon 41.5 Red Gold “Year of the Horse” tells a tale of excellence, symbolism and vital energy.

An ardent design
Behind the expressive power of the scene, lies all of Arnold & Son’s creativity and mastery. The horse, in 18-carat red gold appliqué, is hand engraved. From hooves to mane, every muscle seems to ripple with energy. The black aventurine sky shimmers like a vast, celestial expanse, where distant stars mingle with mountainous reliefs and shadowy woodland undergrowth.

In the horse’s wake, hand-painted golden dust evokes a trail of sparks that ignite one after the other as the animal passes. These glowing flashes reflect its inner fire and untamed spirit. Touches of red and yellow Super-LumiNova, diffusing the same nocturnal shades, transform the scene as the light dims. Under the radiant mother-of-pearl moon, the horse’s majestic silhouette stands out, while the embers smoulder with new intensity. Not far away, the constellations of Cassiopeia and Ursa Major take shape on the lunar disc, completing this dual-faced, dual-display dial.

A noble pedigree
On the case back, a secondary moon-phase display enables fast, accurate setting of the lunar age. The heart of the Perpetual Moon 41.5 Red Gold “Year of the Horse”, the manual winding A&S1512 calibre, follows the lunar cycle with exceptional precision. While a true lunation lasts 29 days, 12 hours, 44 minutes and 2.8 seconds, Arnold & Son have achieved such precision that it would take 122 years for the display to drift by a single day from the actual lunar cycle, provided the watch is kept fully wound.

As for all Arnold & Son movements, the A&S1512 calibre is developed, manufactured, decorated, assembled, adjusted and cased up at the Chaux-de-Fonds manufacture. Equipped with two barrels and beating at 3 Hz, it gives the Perpetual Moon 41.5 Red Gold “Year of the Horse” a generous power reserve of 90 hours.

Chronoswiss Strike Two Stella Blue and Nugget: Where Precision Meets Personality

In the world of independent watchmaking, few designs capture the essence of mechanical artistry and thematic storytelling like the Chronoswiss Strike Two collection. With its signature horizontal regulator layout and exposed gear architecture, the collection is a canvas for both cosmic inspiration and historical homage. The Stellar Blue and Nugget editions, though forged from different visions, share a unified spirit: precision in motion, elevated by craftsmanship.

Architecture of Time

At the heart of both models lies the Chronoswiss Manufacture Caliber C.6000, developed in collaboration with La Joux-Perret. This automatic movement delivers a robust 55-hour power reserve, beating at 4 Hz (28,800 A/h). A skeletonized tungsten rotor, ruthenium-plated Geneva-cut bridges, and polished components reflect the brand’s commitment to mechanical transparency and refinement. Viewed through a sapphire caseback, the movement reveals a radial geometry that echoes the symmetry of the dial above.

The horizontal regulator layout defines the Strike Two identity: a floating hour display at 3 o’clock, central luminous minutes, and a small seconds subdial at 9 o’clock. Two architectural bridges span the dial, exposing the gear train and anchoring the visual rhythm of the watch.

Stellar Blue – A Tribute to Cosmic Velocity

The Stellar Blue edition draws inspiration from the brilliance and motion of stellar light. Its dial features a deep blue CVD-coated base, hand-guillochéd with linear engraving that mimics the trajectory of light through space. A silver rhodium-plated subdial adds contrast, while the luminous minute hand glides across the dial like a comet in orbit.

Encased in matte grey sandblasted stainless steel, the watch offers a futuristic silhouette that complements its celestial theme. Measuring 40 mm in diameter and 12.7 mm in thickness, it wears with elegance and presence. The strap is crafted from white nubuck calfskin leather, lined with blue Alcantara, echoing the dial’s cosmic hue.

Nugget – A Homage to Discovery and Rarity

In contrast, the Strike Two Nugget is a celebration of terrestrial treasure — a mechanical gold rush forged in solid 18ct red gold. Inspired by the thrill of unearthing something precious, the Nugget edition elevates the Strike Two architecture with warmth, weight, and richness.

Its anthracite dial, hand-guillochéd and treated with a galvanic finish, reveals depth and texture. A glossy white lacquered small seconds subdial punctuates the monochrome palette, while the exposed gearwork beneath the hour display adds mechanical drama.

The case, polished and sandblasted, retains the 40 mm diameter and 12.7 mm thickness, but its golden sheen transforms the watch into a statement of rarity. Paired with a black nubuck calfskin strap lined in blue Alcantara, the Nugget balances boldness with refinement..

Two Visions, One Philosophy

Whether inspired by the stars or the soil, the Strike Two Stellar Blue and Strike Two Nugget embody Chronoswiss’s philosophy of independent design, mechanical excellence, and thematic storytelling. Limited to 100 pieces each, these timepieces are not just instruments of time — they are expressions of discovery, crafted for collectors who seek meaning in every detail.

Moritz Grossmann Presents the PERPETUAL CALENDAR

To celebrate 17 years since its rebirth in 2008, Moritz Grossmann unveils a horological milestone: the PERPETUAL CALENDAR. This grand complication embodies the brand's philosophy of timeless precision, combining traditional craftsmanship with modern innovation.

The PERPETUAL CALENDAR is engineered to automatically account for the varying lengths of months and leap years, requiring no manual correction until the year 2100. This makes it one of the most technically demanding and revered complications in fine watchmaking.

The dial is a study in symmetry and clarity. A full 1–31 date scale encircles the dial, with a cup-shaped indicator framing the current date. The month and weekday are displayed on subdials at 3 and 9 o'clock, decorated with Azurage finishing. Leap year and day/night indicators are integrated into the subdials. At 12 o'clock, a poetic moon phase display features a mother-of-pearl moon gliding across a goldstone sky.

At the heart of the watch is the newly developed Calibre 101.13, a hand-wound movement based on the 100.1 calibre with an added perpetual calendar module. It comprises 401 components — 211 for the calendar module and 190 for the base movement. The movement features optimised stopwork, an integrated manual winder, and an escape wheel bearing in the barrel bridge. The finishing adheres to traditional Glashütte standards, with untreated German silver plates, raised gold chatons, and hand-engraved details.

All calendar functions can be adjusted via recessed correctors on the case, operated with a dedicated tool. A sum corrector allows for quick synchronization of all indicators after periods of inactivity.

The PERPETUAL CALENDAR is available in three elegant variants: rose gold with argenté dial (Ref. MG-003906), rose gold with anthracite dial (Ref. MG-003907), and platinum with argenté/anthracite dial (Ref. MG-003904). Each model is paired with a hand-stitched dark brown alligator leather strap and a matching prong buckle.

Moritz Grossmann continues to honour its namesake's 19th-century legacy with a commitment to "Schönstes deutsches Handwerk" — the finest German craftsmanship. The PERPETUAL CALENDAR is a testament to this enduring vision, offering collectors a timepiece that is as poetic as it is precise.
