Arnold & Son has unveiled its new "Perpetual Moon 41.5 Steel Colours of the Moon" collection, a series of highly exclusive, limited-edition timepieces inspired by the changing celestial hues of Earth's natural satellite. Detailed in the official release document, "ENG_A&S PM 41.5 Steel Colours of the Moon.doc", the collection features three distinct versions—the Blue Moon, Golden Moon, and Red Moon—each celebrating a unique atmospheric or seasonal phenomenon that alters the Moon's appearance and has fascinated civilisations throughout history.

Reinterpreting the iconic Perpetual Moon collection, these new models introduce a 41.5 mm stainless-steel case that balances horological exclusivity with everyday versatility. In a watchmaking first, Arnold & Son has applied a pioneering Physical Vapour Deposition (PVD) treatment directly onto precious mother-of-pearl. This innovative process creates deep, shifting reflections across the dials and moon-phase skies, showcasing the natural organic layers of the material with patterns that recall the flowing grain of Damascus steel.

The astronomical precision of the moon phase is enhanced by Super-LumiNova hidden beneath the colored mother-of-pearl moon disc, accompanied by hand-painted luminescent constellations of Cassiopeia and Ursa Major—a poetic tribute to historical mariners who relied on them for navigation. Bringing this celestial mechanics to life is the in-house A&S1512 manual-winding calibre. This movement provides a generous 90-hour power reserve and displays meticulous luxury finishes, including radiating Côtes de Genève and a secondary moon-phase indicator, all visible through the sapphire crystal case back.

Each of the three references is paired with a matching hand-stitched alligator leather strap and secured with a stainless-steel pin buckle. To maintain their extreme exclusivity, production is strictly limited to just 18 pieces per version.

Chronoswiss has officially introduced the Pulse GMT Frosted Guilloche Gold, a striking new expression of modern travel time created in its Atelier Lucerne. Housed in a beautifully sculpted 41mm 18ct (5N) gold case, this timepiece seamlessly brings precious materials into the bold, architectural world of the Pulse design family. Redefining the brand’s classic codes with a sharper, sportier attitude, the watch features Chronoswiss’s iconic onion crown, a partially knurled coin-edge bezel, and an exclusive new integrated black rubber strap. This exclusive, modern masterpiece is strictly limited to just 50 pieces worldwide.

At the heart of this timepiece is an innovative, three-dimensional dial that showcases a revolutionary take on a traditional decorative art. For the first time, a hand-guilloché brass surface is refined using a highly precise sandblasting process that directs ultra-fine synthetic corundum particles onto the dial. The result is a shimmering, frosted finish that transforms the geometric guilloché pattern into a crystalline landscape of light and depth. This contemporary backdrop is beautifully contrasted by polished, blue PVD-coated appliques, blued steel screws, and polished, blued steel hands in the brand's signature "Pyramid" shape.

Powering the watch is the Chronoswiss Manufacture Caliber C.6002, an automatic movement developed in partnership with La Joux-Perret that offers a 55-hour power reserve. Designed specifically for global travelers, the movement features a dedicated dual-time-zone module; home time is tracked on a 12-hour disc at 3 o'clock, a second time zone is displayed via a 24-hour GMT disc at 9 o'clock, and central hands sweep the dial to indicate minutes and seconds. The exquisite inner workings of the caliber are visible through a sapphire crystal case back, revealing a skeletonized tungsten rotor, polished escape wheels, and a ruthenium-plated bridge finished with a classic Geneva cut.

The solid 26-piece gold case, weighing 48 grams, balances satin-finished and sandblasted textures with a partly polished bezel, offering 5 bar (50 meters) of water resistance. Secured to the wrist by a black integrated rubber strap and a matching black DLC-coated stainless steel and 5N gold buckle, the watch represents the ultimate expression of the brand’s "Modern Mechanical" philosophy. By contrasting traditional luxury with high-functioning, contemporary materials, the Pulse GMT Frosted Guilloche Gold is engineered as a sophisticated mechanical companion for an ever-moving world.

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.

Independent manufacture Romain Gauthier has unveiled its latest horological evolution with the release of the C by Romain Gauthier Titanium Edition 39.5. This new iteration introduces a highly anticipated, more compact 39.5 mm Grade 5 titanium case designed to sit effortlessly on a broader range of wrist sizes. Embodying the core philosophy of the collection, the timepiece is built for everyday wearability, blending high-end mechanics with a casual, modern design language that seamlessly integrates into daily life.

Enhancing this newfound versatility, the manufacture introduces its very first interchangeable rubber strap system alongside three expressive new colorways: vibrant blue, energetic orange, and subtle pink. These eye-catching color accents on the dial are matched with corresponding Super-LumiNova hues at night, offering a fresh, lifestyle-oriented aesthetic. The quick-release strap system allows wearers to effortlessly adapt the watch to any mood, outfit, or occasion, transitioning seamlessly between sporty casualness and discreet, refined elegance.

While the exterior boasts a contemporary, relaxed style, the heart of the watch remains deeply committed to haute horlogerie. The in-house manual-winding caliber is gloriously on show through the display back, showcasing finger bridges—historically typical of Romain Gauthier’s birthplace, the Vallée de Joux—reinterpreted with a modern "stepped" architecture. Each Grade 5 titanium bridge is meticulously finished by hand, featuring a highly original dimpled texture achieved through a special hand-engraving technique, set against a beautifully hand-frosted movement mainplate.

Technically astute, the timepiece is equipped with a clever stop-seconds mechanism that uses a snail cam—a nod to the brand’s acclaimed Logical One. Pulling out the crown stops the balance wheel, while pushing it back in prompts the snail cam to turn, delivering an active impulse to help the movement start beating again instantly. Offered as part of the brand's permanent, non-limited collection, the C by Romain Gauthier Titanium Edition 39.5 represents a masterful synthesis of superlative hand-finishing and modern, adaptable luxury.
