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.

Opus Dakar Sundown: A Two-Tone Symphony of Desert Sunset and Fine Skeletonized Horology

Chronoswiss has officially introduced the Opus Dakar Sundown, a striking new interpretation of the celebrated Opus Dakar that captures the fleeting magic of sunset over the desert. Housed in a distinctive 41mm two-tone case crafted from stainless steel and 18ct red gold, the timepiece masterfully blends the rugged spirit of adventure with refined luxury. The warm glow of precious metal flows seamlessly into the robust steel construction, mirroring the final golden rays dancing across endless dunes. This ultimate celebration of contrasts is beautifully completed by a sand-colored nubuck leather strap that evokes the warm tones of sunlit, weathered terrain.

At the heart of the watch beats the Chronoswiss Manufacture Caliber C.741S, a fully skeletonized automatic chronograph movement that transforms every measurement of time into a visual spectacle. Designed for legibility and visual complexity, the central chronograph seconds hand sweeps the openworked dial in harmony with a 30-minute counter at 12 o'clock and a 12-hour counter at 6 o'clock. A running small seconds display at 9 o'clock provides a constant indication of the movement's heartbeat, while a highly unique, analogue pointer date display at 3 o'clock enhances its everyday practicality.

The skeletonized, CVD-coated brown dial draws inspiration from the rich palette of the desert, where warm tones create a composition that is both timeless and adventurous. By exposing the intricate mechanics beneath the surface, every skeletonized bridge, wheel, and component directly contributes to a captivating, mechanical canvas. The hands are crafted in the elegant Breguet Losange shape and rhodium-plated to ensure striking contrast against the dark, galvanic black perlage of the base plate.

Crafted in solid 23 pieces, the 41mm case features an 18ct red gold bezel with partial knurling, a screw-down case back with a red gold coin-edge ring, and Chronoswiss’s iconic onion crown. The total weight of gold used in this exceptional construction is 21.4 grams. Offering a water resistance of 3 bar (30 meters), the watch is equipped with screw-in lugs utilizing the patented Autobloc system. For over three decades, the Opus collection has embodied the bold spirit of Chronoswiss; the Opus Dakar Sundown brilliantly reimagines this legacy, shaped by craftsmanship and illuminated by one of nature's most spectacular moments.

Moritz Grossmann GMT Guilloche Limited Edition Dual Time Zone Watch with Hand-Guilloché Dial

The Moritz Grossmann GMT Guilloche is a celebration of global exploration and fine German watchmaking. Inspired by the colors of nature and the rhythm of travel, this dual time zone watch is available in two striking dial variants: matte green, evoking serene meadows and hidden coves, and vibrant orange, reminiscent of the glow of a setting sun.

Dual Time Functionality

Designed for the modern traveler, the GMT Guilloche features a 24-hour time zone ring encircling the dial. A distinctive arrow-shaped hand tracks a second time zone, offering intuitive day-night orientation. Local time is displayed via central hour and minute hands, with a small seconds subdial at 6 o’clock. A dedicated crown at 10 o’clock allows seamless adjustment of the second time zone without affecting the main time.

Masterful Craftsmanship

Each dial is hand-engraved using the traditional guilloché technique, creating intricate geometric patterns that shimmer with light. The green dial is paired with blued steel hands, while the orange dial features polished steel hands—both handcrafted in Glashütte.

Engineered for Precision

Inside the watch beats the calibre 100.8, a manually wound movement crafted in-house and regulated in five positions. It features 253 components, 26 jewels, and signature Grossmann innovations including the 2/3 plate with raised gold chatons, cantilevered balance cock with micrometer screw, and a separately removable winding mechanism. The second time zone mechanism is seamlessly integrated on the dial side, ensuring precision and harmony.

Limited Edition

Encased in stainless steel and fitted with a hand-stitched black alligator leather strap, each GMT Guilloche model is strictly limited to 8 pieces worldwide, making it a rare collector’s item.

Discover the Art of Glashütte

Moritz Grossmann continues to honor its founder’s legacy by blending traditional craftsmanship with modern innovation. The GMT Guilloche is a wearable work of art—an invitation to wear the world on your wrist.

Greubel Forsey Introduces the Balancier QM: A New Pinnacle of Haute Horlogerie

Independent manufacture Greubel Forsey has unveiled the Balancier QM ($GF09cm$), marking a historic milestone for the workshop by officially naming its highest, most uncompromising hand-finishing standard: Qualité Musée (Museum Quality). While this meticulous level of execution has been quietly embedded into every single timepiece crafted by the Atelier since its founding in 2004, the Balancier QM is the first model to formally carry the designation. Driven forward by a dedicated research wing within the brand’s proprietary EWT (Experimental Watch Technology) Laboratory, this standard mandates that every individual component, whether fully visible through the sapphire crystals or buried deep within the gear train, must hold up as a standalone work of art.

The mechanical architecture of the Balancier QM is a tour de force of in-house micro-engineering and innovation. Most notably, the timepiece features a specialized hairspring manufactured entirely in-house from the raw alloy stage up—a rarity in modern watchmaking accomplished via restored antique machinery. This is paired with an impressive $12.60\text{ mm}$ variable-inertia balance wheel and a cutting-edge bi-level escapement system that utilizes unique convex pallet-jewels, allowing light to softly diffuse through the rubies rather than abruptly reflecting off flat surfaces. Illustrating the immense labor required for the Qualité Musée standard, the steel balance wheel bridge alone requires seven distinct hand-finishing techniques, ranging from flawless mirror barrel polishing to extra-large $0.40\text{ mm}$ hand-polished bevels.

Visually, the timepiece presents an intricately layered, three-dimensional landscape neatly organized within a highly compact 39.60mm white gold case. The movement architecture encourages deep visual exploration; the escapement is nestled into the lowermost depths of the chassis, while the eye naturally ascends past a high-set small seconds sub-dial, flame-blued polished steel hands, and a raised chapter ring. Beneath this upper track, a power-reserve indicator slips mysteriously across a dedicated sector to track the watch's 72-hour chronometric power delivery, sustained by two fast-rotating, series-coupled mainspring barrels. True to Greubel Forsey’s signature underplayed luxury, the words "Qualité Musée" are entirely absent from the dial, hidden instead on a secret internal plate deep inside the movement.

Limited to just 33 exclusive timepieces worldwide, the Balancier QM represents a deliberate strategic pivot for Greubel Forsey toward smaller, more wearable case dimensions without sacrificing an ounce of technical complexity. The manufacture openly acknowledges that achieving this level of structural perfection across all 298 movement parts demands an extraordinary expenditure of time, which will intentionally reduce the company's overall production volume heading into 2027. Looking ahead, the Qualité Musée standard will serve as the foundation for a series of compact releases, including a highly anticipated movement under development at the EWT lab featuring a gear train crafted entirely from solid gold.
