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.

Chronoswiss Unleashes the Q-Repeater – A Chiming Masterpiece combining Legacy and Future

Time is not just seen—it is heard.

Chronoswiss presents the Q-Repeater Scream and Q-Repeater Blue Note, two extraordinary Quarter Repeater timepieces that merge the sonic beauty of timekeeping with cutting-edge mechanical architecture. The watchmakers from Lucerne have created a bold reinvention of sound, design, and independent watchmaking deeply rooted in Chronoswiss history. Housed in a Grade 5 titanium case, these 42mm skeletonized masterpieces reveal the intricate mechanisms behind their chiming complication. Every press of the 10 o’clock pusher activates the mesmerizing quarter repeater function, where hammers strike to audibly indicate the hours and quarter-hours, making time a true sensory experience. At its core lies a legacy movement, rooted in the vision of Chronoswiss founder Gerd-Rüdiger Lang. First introduced in the 1990s and exclusively produced for Chronoswiss, this legacy caliber has been taken from our archives, meticulously restored, refined, and reborn in the Atelier Lucerne, making these two timepieces an extraordinary link between the past and the future.

What the watchmakers of Lucerne have achieved here is the ultimate evolution—the heart beats with the legacy of the past, carrying its passion and memories, while the body is Modern Mechanical, engineered for the next century and beyond.

Q-Repeater Scream – A Chiming Rebel
This is not your grandfather’s repeater. The Q-Repeater Scream is a wild, untamed spectacle—combining bold design and mechanical precision unlike anything in watchmaking. The multi-level dial is a skeletonized stage and at the same time part of the movement, where CVD-coated bridges in electric blue, orange, and purple hold the Paraiba green minute ring, the floating hour, as well as the small seconds rings. At 1 o’clock, the heart of this spectacle is fully visible: the striking hammers, set to release a mechanical rock concert at the press of a button.

As you can tell by the name already, it’s not just about what you see. It’s about what you hear. Every chime is a scream of innovation, breaking free from the traditions of classical repeater watches. Even the legacy movement itself becomes part of the gig, holding the Super-LumiNova blocks and hand-guilloché bridges—one of which moves when the mechanism is activated, adding to the dynamic energy of the dial. The watchmakers of Lucerne refer to the glowing ceramic blocks as “chicken heads”, a nod to the iconic amplifier knobs found on rock concert stages—designed to crank up the sound and electrify the crowd.

Caged in 42mm of titanium, the Q-Repeater Scream is limited to just 25 pieces. As only very few of the legacy movements exist this might be the final tour of the band. Each piece is a testament to mechanical defiance and unfiltered artistry. A Quarter Repeater like no other— built for collectors who dare to embrace the wild side of watchmaking.

Q-Repeater Blue Note – The Sound of Elegance
For those who seek a symphony rather than rock n roll, the Q-Repeater Blue Note takes a more refined yet equally innovative approach. Inspired by the expressive power of jazz and blues, the navy blue CVD-coated skeletonized dial and bridges which are part of the movement, play on contrasts with a silver hour ring and luminous white Super-LumiNova markers, creating a harmonious composition of mechanics and design.

In music, a blue note is an altered pitch—intentionally deviating from the standard, creating a sound that is richer, deeper, and full of soul. One could say – the Chronoswiss way of making watches – and music. The Q-Repeater Blue Note embodies this philosophy, blending traditional watchmaking with a contemporary edge, offering a timeless yet unconventional melody of time.

Like the Scream, the Blue Note features the multi-level regulator dial, a fully visible quarter repeater mechanism, and a restored historical movement, revised and refined by thewatchmakers in Lucerne. It is a timepiece that doesn’t just mark time—it composes it.

Time Reimagined, Sound Reinvented
The Q-Repeater Scream and Q-Repeater Blue Note stand as testaments to Chronoswiss’ relentless drive to push boundaries. With only 25 pieces per model, these Quarter Repeaters are more than just rare; they are audible declarations of mechanical mastery.

This is not just a watch. It is an experience. A fusion of sound and time, crafted for those who appreciate the extraordinary. Chronoswiss has never followed the expected path. The future of independent watchmaking starts here—with a chime.

Back in sleek anthracite: Armin Strom unveils the One Week Manufacture Edition

Biel/Bienne, Switzerland, 26 June 2024: Following the inaugural redesigned One Week First Edition that made its debut in 2023, Armin Strom unveils a new version of the successor to its first-ever manufacture movement with the One Week Manufacture Edition. The highly architectural openworked movement, housed in a sleek and sporty steel case with an integrated bracelet, is now presented in a range of grey and anthracite hues. Limited to 100 pieces, the One Week Manufacture Edition foregoes colour to bring out the beauty of its uniquely constructed manual calibre.

15 years ago, independent watchmaking brand Armin Strom took a major leap that would forever change its trajectory. Realising that the path to true independence lies in mastering every step of the process, it established its very own manufacture in Biel. A year later, the first timepiece produced by its vertically integrated manufacture was unveiled: the One Week. Entirely developed and manufactured in-house and designed with symmetrical harmony in mind, it stood out thanks to its unique movement architecture featuring two barrels that together provide a seven-day power reserve. This milestone marked the beginning of many new calibres and innovations by the Armin Strom manufacture, showcasing their dedication to the science of movement and garnering the admiration and respect of even the most discerning and seasoned collectors.

The new One Week Manufacture Edition completely reimagines this milestone calibre in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.

As Armin Strom founder Serge Michel notes: “Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.”

Sporty yet classy, this model exudes calmness and serenity with its anthracite tones and the symmetrical harmony of its in-house movement.

Introduction of assertive new black dials for the C by Romain Gauthier Titanium Edition Bracelet

Released initially with a grey dial and then with a Lever de Soleil color dial, the C by Romain Gauthier Titanium Edition Bracelet is now featured with two new dials: a three-dimensional straight grained structured dial in Grade 5 black titanium with white details and a black sapphire openwork dial with blue and white accents.

The three-dimensional straight grained black titanium dial provides an even more assertive character with its textured surfaces. The sharp contrast between the white details and the dark background enhances the time indications. This dial embodies a distinctly modern design while maintaining excellent readability, even in low-light conditions, thanks to the use of Super- LumiNova on the indexes, numerals, and hands.

As for the sapphire openwork dial, it reveals the intricate components of the movement, showcasing the brand's sophisticated watchmaking engineering and artisanal craftsmanship. This openwork design creates a captivating interplay between transparency and structure, transforming the watch into a true technical and aesthetic masterpiece. When Romain launched the first edition of C by Romain Gauthier in 2021, it was clearly stated that this new caliber would lead the brand to new horizons. One year later, a new door has been opened with the arrival of the brand's first metal bracelet.

Sober and contemporary, propitious to variations and adaptations, C by Romain Gauthier was an obvious choice for the creation of a metal bracelet. The desire of modernity, comfort and ergonomic already initiated during the conception of the first edition, reinforced the development of this integral timepiece on a titanium bracelet - light, resistant, modern and sophisticated. Aesthetically, it was important to Romain that the bracelet and the watch become one. As he said: "The bracelet is the case, and the case is the bracelet". This desire is reflected in the fusion of these two elements, a timepiece as a whole that cannot be dissociated.

In keeping with Romain's vision - The Evolution of Tradition - this new technical and contemporary element requires a high level of craftsmanship and hand finishing. Each link is composed of hand-polished and satin-finished surfaces that play with the light and reflect the technical nature of the bracelet and the piece in general.

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.

gérald genta Introduces Gentissima Oursin 41 with Meteorite Dials

gérald genta continues its legacy of audacious elegance with the launch of two new references in the Gentissima Oursin collection: Blue Meteorite and Green Meteorite. These timepieces mark a bold evolution of the iconic design first imagined by Mr. Gérald Genta in 1994, inspired by the delicate yet resilient form of the sea urchin.

A Design Born from Nature and the Cosmos
The Gentissima Oursin 41 features a 41mm sandblasted Grade 5 titanium case, meticulously set with 234 white gold beads, echoing the organic geometry of the sea urchin. At its heart lies a dial carved from a fragment of meteorite—a material born from the stars—making each watch a unique, one-of-one creation. The natural crystalline structure of meteorite ensures that no two dials are alike, offering collectors a truly rare expression of artistry.

Sporty-Chic Meets Haute Horlogerie
Combining rubber straps and titanium architecture with luxurious gold accents, the Gentissima Oursin 41 is designed for everyday wearability without compromising sophistication. A curved sapphire crystal, faceted with a subtle octagonal profile, protects the dial and enhances its dynamic character. Gold hands filled with Super-LumiNova featuring a pink hue—a tribute to Mr. Genta’s favorite color—ensure legibility and elegance.

Mechanical Excellence
Inside beats the Zenith Elite GG-005 automatic movement, boasting a 50-hour power reserve, 4 Hz frequency, and an 18K yellow gold oscillating mass, visible through a sapphire caseback. With 50m water resistance and a comfortable rubber strap, this timepiece is as practical as it is artistic.
