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

JUNE 24 2025    |    Novelties

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.

To mark the 16th anniversary of the manufactory, Moritz Grossmann presents the limited-edition ENAMEL ROMAN Vintage

Black is the absence of light. This is the physical definition of a colour that is synonymous with classicism and elegance. At Moritz Grossmann, black is used to form stylish contrasts and also serves as a testament to the highest standards of craftsmanship. The limited-edition ENAMEL ROMAN Vintage, for example, has an enamel dial whose manufacture presents multiple challenges. With this, Moritz Grossmann has chosen the occasion of its 16th birthday to once again shine the spotlight on the expertise of the ateliers and workshops in Glashütte.

Tradition requires renewal, otherwise it remains stagnant in the past and cannot survive. This is an approach that Moritz Grossmann has embodied since 2008: the manufactory opened 16 years ago as a tribute to one of the most exceptional personalities in the history of watchmaking in Glashütte. Moritz Grossmann was an innovative watchmaker and, with the founding of the German Watchmaking School in Glashütte, influenced a generation of artisans.

His values and vision now live on in the Moritz Grossmann manufactory, which crafts a small but exquisite collection of sophisticated watches that always remain true to the standards of the man who gave the manufactory its name. Characteristics of these timepieces include exclusive manufactory movements with innovative details that are designed, made and finely decorated in-house in the company’s own workshops. The highest of standards also come into play when finishing the watches, as impressively demonstrated by the special model marking the 16th anniversary of the manufactory.

A Star Fragment, Guardian of Time: The Grand Planetarium Eccentric Meteorite

Time and space converge in the latest masterpiece of haute horlogerie: the Grand Planetarium Eccentric Meteorite. This extraordinary timepiece is crafted from a genuine meteorite fragment—once part of an asteroid’s core, drifting through space for billions of years before falling to Earth 50,000 years ago. Now, this celestial relic has been transformed into an exceptional watch, uniting cosmic heritage with unparalleled horological innovation.

At the heart of this timepiece lies a groundbreaking complication: the Eccentric Planetarium, the only mechanical Grand Planetary Complication in the world that accurately displays all eight planets—Mercury, Venus, Earth and her Moon, Mars, Jupiter, Saturn, Uranus, and Neptune—moving in real time around the Sun. This breathtaking mechanism captures the celestial dance of our Solar System with unmatched precision, making it a true marvel of both astronomy and watchmaking.

A Celestial Fusion of Science and Art
Master watchmaker Pim Koeslag has meticulously sculpted this timepiece, ensuring that its construction reflects the grandeur of its cosmic origins. The meteorite case, weighing 47 grams, is carefully crafted out of a 1.09 kg space stone. This extraordinary material shaped by the universe itself, features a unique Widmanstätten pattern, formed over millions of years of slow cooling in space, making each case truly one of a kind.

The dial is a celestial spectacle in itself: crafted from aventurine glass (goldfluss), it mimics the night sky, complete with zodiac constellations. The Eccentric Planetarium features hand-painted planetary orbits, while the meteorite dial ring, set between Mars and Jupiter, signifies the asteroid belt and contains real fragments of a martian nakhlite meteorite —a piece of another world encased within this exceptional timepiece.


A Timepiece Beyond Time
Encased in domed sapphire crystal, the 44mm meteorite case showcases the celestial ballet within. The sapphire crystal case-back reveals the movement’s intricate craftsmanship, while the dark blue hand-stitched leather strap and platinum folding clasp complete this cosmic masterpiece.

“The Grand Planetarium Eccentric Meteorite is more than a watch. It is a link between humanity and the cosmos, a way to wear the universe on your wrist,” says Pim Koeslag.

This timepiece is a tribute to time itself. From a star’s death to an asteroid’s journey, from its fall to Earth to its transformation into an exceptional watch—each second it measures is an echo of the vast cosmic history it carries.

An Exclusive, Limited Edition for Collectors
The Grand Planetarium Eccentric Meteorite is available in a strictly limited edition, with a maximum of 3 pieces, depending on the avaibility and quality of the rough meteorite material. So far, Christiaan van der Klaauw has been able to produce only 2 pieces from the available material, making this timepiece an exceptionally rare collector’s item. This extraordinary creation offers the unique opportunity to own a fragment of a star, forever marking the passage of time.

About Christiaan van der Klaauw
Christiaan van der Klaauw is one of the most prestigious watchmaking houses in the Netherlands, specializing in astronomical watches. Founded in 1974, the brand has distinguished itself by its ability to integrate astronomical complications innovatively and artistically into high-precision timepieces. The Grand Planetarium eccentric model is one of its most iconic Grande Complication, representing the quintessence of art and science.

Armin Strom Unveils the Gravity Equal Force Ultimate Sapphire Rose Gold — A Masterpiece of Mechanics and Elegance

Independent Swiss watchmaker Armin Strom proudly presents the Gravity Equal Force Ultimate Sapphire Rose Gold, a timepiece that exemplifies the brand’s commitment to horological innovation, artisanal craftsmanship, and visual harmony.

Encased in 18K rose gold, this limited-edition watch features a sculptural movement architecture that plays with tone and texture. A brown guilloché mainplate, rose gold-colored bridges, and a floating off-centre sapphire dial create a refined and coherent composition. The watch is paired with a matte brown nubuck leather strap, adding an earthy elegance to the overall aesthetic.

At the heart of the timepiece is the Caliber ASB19, Armin Strom’s groundbreaking automatic movement. It incorporates a patented stop-work declutch mechanism and Geneva cross within the barrel, ensuring consistent torque delivery throughout its 72-hour power reserve. A micro-rotor enables efficient winding while preserving the symmetry and visibility of the movement — a hallmark of Armin Strom’s design philosophy.

Every component, visible or hidden, is hand-finished to haute horology standards. Techniques such as beveling, straight-graining, perlage, Geneva stripes, and black-polished screws are applied with precision and care. The mainplate features a “grain d’orge” guilloché pattern, crafted by master artisan Kari Voutilainen using a traditional hand-operated machine.

This exceptional timepiece is limited to just 25 pieces per year, making it a rare and radiant statement in the world of independent watchmaking. It is a testament to Armin Strom’s philosophy: Mechanics First. Always.
