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.

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.

Moritz Grossmann Unveils TOURBILLON Titanium and TOURBILLON Tremblage: Tradition Meets Modernity

The tourbillon has long been regarded as one of the most fascinating complications in the history of watchmaking. Moritz Grossmann now reinterprets this horological icon with two extraordinary creations: TOURBILLON Titanium and TOURBILLON Tremblage. These timepieces embody the manufactory’s philosophy of blending traditional craftsmanship with contemporary aesthetics.

The TOURBILLON Titanium combines the technical sophistication of a flying three-minute tourbillon with the modern appeal of a titanium case. Its solid silver dial, adorned with a fine grain d’orge guilloche pattern, reflects the artistry of hand-guided engraving techniques. The result is a watch that is both lightweight and visually striking, offering a perfect balance of durability and elegance.

The TOURBILLON Tremblage, on the other hand, celebrates the beauty of historical handcraft. Its warm rose-toned dial is meticulously engraved using the traditional tremblage technique, creating a unique matte texture that softens light and enhances depth. Paired with a white gold case, this model exudes timeless sophistication while showcasing the manufactory’s dedication to artisanal excellence.

Both models are powered by the hand-wound calibre 103.0, featuring a flying three-minute tourbillon and patented innovations for precision timekeeping. Every component is finished by hand, from the engraved plates to the polished screws set in gold chatons, reflecting the highest standards of Glashütte watchmaking. These creations are more than timepieces—they are works of art that unite heritage and modernity in perfect harmony.

Traditional craftsmanship with modern appeal - Moritz Grossmann TREMBLAGE Green

Moritz Grossmann proudly unveils the TREMBLAGE Green, a limited edition timepiece that redefines elegance through heritage craftsmanship and a bold new aesthetic. Available in rose gold and white gold, with only 8 pieces of each, this extraordinary watch is a tribute to the art of traditional engraving and the timeless beauty of horological design.

At the heart of the TREMBLAGE Green lies a dial crafted from German silver, meticulously hand-engraved using the rare tremblage technique. This centuries-old method creates a fine, matte texture that diffuses light with a soft, meditative glow. The dial is finished in a deep, complex green—symbolizing renewal, harmony, and depth—making it a standout piece that remains understated and refined.

Encased in a 41 mm case of 750/000 rose or white gold, the watch is powered by the in-house calibre 100.1, a hand-wound movement visible through a sapphire crystal case back. Every component is hand-finished, from the Glashütte ribbing and polished bevels to the engraved balance cock. The watch features hours, minutes, and a small seconds display with a stop-second function, all operated via a gold crown and lateral pusher.

Completing the look is a hand-stitched dark brown alligator leather strap, offering both comfort and sophistication. The TREMBLAGE Green is not just a timepiece—it is a celebration of “Schönstes deutsches Handwerk” (the finest German craftsmanship), brought to life with modern sensibility and timeless appeal.

Arnold & Son Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.
