TREMBLAGE Gold

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.

oritz Grossmann celebrates the 200th birthday of its founder with the launch of the TEFNUT 36 Silver-Plated by Friction Turquoise Blue, a timepiece limited to just 12 pieces worldwide. This special anniversary edition combines traditional 19th-century craftsmanship with a modern aesthetic, paying homage to the visionary watchmaker, scientist, and founder of the German Watchmaking School. The manufactory in Glashütte continues to honor this rich heritage by blending historical techniques with contemporary design.

The dial of the watch is crafted using a meticulous silver-plating by friction technique, also known as silver-plating by grit, which is executed entirely by hand through multiple complex steps involving silver powder, salt, tartar, and water. This traditional process imparts a velvety, matte structure with remarkable optical depth, further enhanced by a unique green-tinged blue hue that shifts dynamically depending on the angle and lighting. Contrasting the textured surface are engraved Roman numerals lacquered in blue, alongside the historic 1875 'M. Grossmann' logo, scale markers, and manually crafted steel hands annealed to a vibrant blue hue.

Housed in a slender and expressive 36-millimeter stainless steel case with a flat profile, the watch is designed to offer exceptional comfort and elegance on any wrist. It is complemented by a hand-stitched grey kudu leather strap featuring a pin buckle in stainless steel. Inside ticks the manufacture calibre 102.1, a hand-wound mechanical movement measuring just 3.45 millimeters in thickness, featuring a pillar movement architecture, a three-fifths plate, a stepped balance cock with a Grossmann micrometer screw, and a special '1826' anniversary engraving.

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.
