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 Tribute 1 Green: A Celebration of Nature’s Elegance

Armin Strom introduces the Tribute 1 Green, a refined dress watch that pays homage to the timeless beauty of nature. Limited to just 50 pieces, this new release brings forest-inspired tones to the brand’s most elegant collection, combining artisanal craftsmanship with modern mechanical innovation.

A Forest-Inspired Masterpiece

The Tribute 1 Green features a striking off-centre dial in forest green, adorned with a hand-engraved grain d’orge guilloché pattern and crisp white Roman numerals. A frosted subdial adds depth and texture, while the green Alcantara leather strap with off-white stitching completes the composition with understated sophistication. The openworked motor barrel, secured by a polished finger bridge in stainless steel, echoes the case design and showcases Armin Strom’s signature fusion of symmetry and mechanical artistry. The 38 mm stainless steel case, with anti-reflective sapphire crystals front and back, ensures optimal clarity and elegance.

Exceptional Performance

At the heart of the Tribute 1 Green is the manual-winding Manufacture Caliber AMW21, offering an impressive 100-hour power reserve. This is made possible by the brand’s patented equal force barrel, designed for efficiency and compactness. Operating at 25,200 vibrations per hour (3.5 Hz), the movement reflects Armin Strom’s technical mastery, with 97% of components produced in-house.

Haute Horlogerie, Hand-Finished

Every Tribute 1 Green is a testament to traditional watchmaking. The case features brushed and polished surfaces, finished entirely by hand. Inside, the movement is decorated with Geneva stripes, circular graining, and a mirror-polished finger bridge, all executed by Armin Strom’s skilled artisans.

True to the brand’s commitment to excellence, each watch is assembled twice—once for mechanical precision and again after decoration—to ensure the highest standards of performance and aesthetics.

DANIEL ROTH Unveils the Extra Plat Rose Gold Skeleton

A contemporary expression of classical proportion, revealing the architecture of high watchmaking
 

DANIEL ROTH presents the Extra Plat Rose Gold Skeleton, a new interpretation of one of the Maison’s most emblematic creations. Remaining faithful to the proportions and restrained elegance of the Extra Plat, this latest iteration introduces skeletonisation for the first time in the brand’s modern revival, allowing the inner architecture of the watch to take centre stage.

Conceived in the spirit of La Montre Objet d’Art, the Extra Plat Rose Gold Skeleton preserves the calm geometry of the double‑ellipse case while offering a transparent view into the movement, transforming technical construction into a visual and artistic experience.

The Extra Plat: A signature revisited
Simplicity, when executed with absolute precision, has long been central to the identity of DANIEL ROTH. During the early years of his independent career, Mr. Roth considered the Extra Plat a complication in its own right, favouring it for the technical discipline required to achieve true thinness and perfect proportion.

Defined by its double‑ellipse case and balanced architecture, the Extra Plat became a cornerstone of the Maison’s aesthetic vocabulary in the early 1990s. While Daniel Roth produced skeletonised versions of select complications during that period, the Extra Plat itself was never skeletonised. This new creation therefore marks a respectful yet meaningful evolution, expanding the expressive range of the Extra Plat while remaining faithful to its original spirit.

The DR002SR calibre: a skeletonised rose gold heart
At the centre of the Extra Plat Rose Gold Skeleton is the new manually wound calibre DR002SR, developed and manufactured entirely at La Fabrique du Temps Louis Vuitton under the supervision of master watchmakers Michel Navas and Enrico Barbasini.

Based on the DR002, the DR002SR has been re‑engineered from the ground up specifically for skeletonisation. The bridges and plates have been reshaped to maximise openness and visual clarity, while preserving structural rigidity and chronometric performance. Crafted in solid 18k 5N rose gold, the movement mirrors the warmth of the case and provides an ideal canvas for traditional hand finishing.


Transparency in motion
Skeletonisation is an exercise in reduction and balance. With the DR002SR, DANIEL ROTH brings this principle to its highest expression. The calibre reveals a wealth of hand‑executed details, including numerous hand‑polished internal angles, black‑polished steel components, and meticulously bevelled bridges—finishes that can only be achieved by skilled artisans and never by machine.

Despite its openworked construction, the DR002SR retains a power reserve of 65 hours and a frequency of 4 Hz, underscoring the Maison’s commitment to both technical integrity and timeless aesthetics.


Slim proportions, uncompromised structure
Housed in a 38.6 × 35.5 mm double‑ellipse case crafted in 18k rose gold, the Extra Plat Rose Gold Skeleton measures just 6.9 mm in thickness. This exceptional slenderness ensures that the watch remains true to the Extra Plat philosophy of discreet elegance and effortless wearability.

Produced in extremely limited numbers each year, the Extra Plat Rose Gold Skeleton is intended for collectors who value traditional high watchmaking expressed with clarity, restraint, and depth.
