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.

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.

Independent manufacture Romain Gauthier illuminates its modern horological vision with the unveiling of the C by Romain Gauthier Titanium Edition Bracelet Lumen dial (Ref. MON00585). For the very first time, the brand integrates a full Super-Luminova dial into its celebrated Freedom collection, using light itself as a core design material. Deliberately paired with the C by Romain Gauthier Titanium Edition Bracelet—available for the first time in a limited edition of just 28 pieces—this creation redefines nocturnal legibility with ergonomic, everyday titanium luxury.

By day, the timepiece displays a refined, crisp white aesthetic anchored by sharp Grade 5 titanium numerals, indices, and hands. When darkness falls, the entire watch face transforms into a brilliant blue glow, creating a striking contrast that ensures effortless readability in any lighting condition. The integrated Grade 5 titanium bracelet—meticulously finished with alternating satin-brushed and hand-polished facets—flows seamlessly from the 41mm x 9.55mm case (47.8mm lug-to-lug), providing lightweight comfort and an uninterrupted, architectural silhouette.

Beneath the luminous dial lies an uncompromising expression of high-end Swiss watchmaking. Visible through the sapphire display back, the in-house hand-wound calibre crafted in natural Grade 5 titanium showcases Romain Gauthier’s heritage from the Vallée de Joux through modern "stepped" finger bridges. Each bridge is meticulously decorated with an exclusive hand-engraved dimpled texture, standing out against a hand-frosted movement mainplate while delivering a robust 60-hour power reserve.

Technical precision remains central to the manufacture's DNA, highlighted by the inclusion of a clever stop-seconds mechanism driven by a snail cam—a signature innovation inspired by the acclaimed Logical One. Pulling the off-center crown halts the balance wheel, while pushing it back in triggers the snail cam to deliver a subtle physical impulse, ensuring the movement restarts instantly. Strictly limited to 28 pieces worldwide, the C by Romain Gauthier Titanium Edition Bracelet Lumen dial represents an extraordinary convergence of glowing nighttime drama and superlative independent watchmaking.
