Arnold & Son Unveils Perpetual Moon 41.5 Red Gold “Year of the Horse” – A Tribute to the Fire Horse

Mystical, untamed and dazzling, the Perpetual Moon 41.5 Red Gold “Year of the Horse” follows in the footsteps of Arnold & Son’s Chinese zodiac collections. In the year spanning 2026 and 2027, the Fire Horse will set the astrological tone for connoisseurs of watchmaking and métiers d’art. To celebrate this flamboyant sign, Arnold & Son presents a limited edition of eight pieces, housed in 41.5-mm red gold cases. And while the noble animal is ever alert, it is at night that the full extent of its fiery, mysterious and incandescent nature is revealed.

A horse rears on a hill top – a commanding silhouette carved out against a star-studded sky, surrounded by the sparks of a metaphorical fire. This is Arnold & Son’s interpretation of the Fire Horse, the sign that will succeed the Wood Snake on 17 February 2026. For the sixth consecutive year, Arnold & Son is back in the saddle, drawing on the full breadth of its artistic savoir-faire. Miniature painting, three-dimensional engraving, fine stonework and the refined finishing of an astronomical moon-phase calibre: the Perpetual Moon 41.5 Red Gold “Year of the Horse” tells a tale of excellence, symbolism and vital energy.

An ardent design
Behind the expressive power of the scene, lies all of Arnold & Son’s creativity and mastery. The horse, in 18-carat red gold appliqué, is hand engraved. From hooves to mane, every muscle seems to ripple with energy. The black aventurine sky shimmers like a vast, celestial expanse, where distant stars mingle with mountainous reliefs and shadowy woodland undergrowth.

In the horse’s wake, hand-painted golden dust evokes a trail of sparks that ignite one after the other as the animal passes. These glowing flashes reflect its inner fire and untamed spirit. Touches of red and yellow Super-LumiNova, diffusing the same nocturnal shades, transform the scene as the light dims. Under the radiant mother-of-pearl moon, the horse’s majestic silhouette stands out, while the embers smoulder with new intensity. Not far away, the constellations of Cassiopeia and Ursa Major take shape on the lunar disc, completing this dual-faced, dual-display dial.

A noble pedigree
On the case back, a secondary moon-phase display enables fast, accurate setting of the lunar age. The heart of the Perpetual Moon 41.5 Red Gold “Year of the Horse”, the manual winding A&S1512 calibre, follows the lunar cycle with exceptional precision. While a true lunation lasts 29 days, 12 hours, 44 minutes and 2.8 seconds, Arnold & Son have achieved such precision that it would take 122 years for the display to drift by a single day from the actual lunar cycle, provided the watch is kept fully wound.

As for all Arnold & Son movements, the A&S1512 calibre is developed, manufactured, decorated, assembled, adjusted and cased up at the Chaux-de-Fonds manufacture. Equipped with two barrels and beating at 3 Hz, it gives the Perpetual Moon 41.5 Red Gold “Year of the Horse” a generous power reserve of 90 hours.

gérald genta Introduces Gentissima Oursin 41 with Meteorite Dials

gérald genta continues its legacy of audacious elegance with the launch of two new references in the Gentissima Oursin collection: Blue Meteorite and Green Meteorite. These timepieces mark a bold evolution of the iconic design first imagined by Mr. Gérald Genta in 1994, inspired by the delicate yet resilient form of the sea urchin.

A Design Born from Nature and the Cosmos
The Gentissima Oursin 41 features a 41mm sandblasted Grade 5 titanium case, meticulously set with 234 white gold beads, echoing the organic geometry of the sea urchin. At its heart lies a dial carved from a fragment of meteorite—a material born from the stars—making each watch a unique, one-of-one creation. The natural crystalline structure of meteorite ensures that no two dials are alike, offering collectors a truly rare expression of artistry.

Sporty-Chic Meets Haute Horlogerie
Combining rubber straps and titanium architecture with luxurious gold accents, the Gentissima Oursin 41 is designed for everyday wearability without compromising sophistication. A curved sapphire crystal, faceted with a subtle octagonal profile, protects the dial and enhances its dynamic character. Gold hands filled with Super-LumiNova featuring a pink hue—a tribute to Mr. Genta’s favorite color—ensure legibility and elegance.

Mechanical Excellence
Inside beats the Zenith Elite GG-005 automatic movement, boasting a 50-hour power reserve, 4 Hz frequency, and an 18K yellow gold oscillating mass, visible through a sapphire caseback. With 50m water resistance and a comfortable rubber strap, this timepiece is as practical as it is artistic.

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.

Back in sleek anthracite: Armin Strom unveils the One Week Manufacture Edition

Biel/Bienne, Switzerland, 26 June 2024: Following the inaugural redesigned One Week First Edition that made its debut in 2023, Armin Strom unveils a new version of the successor to its first-ever manufacture movement with the One Week Manufacture Edition. The highly architectural openworked movement, housed in a sleek and sporty steel case with an integrated bracelet, is now presented in a range of grey and anthracite hues. Limited to 100 pieces, the One Week Manufacture Edition foregoes colour to bring out the beauty of its uniquely constructed manual calibre.

15 years ago, independent watchmaking brand Armin Strom took a major leap that would forever change its trajectory. Realising that the path to true independence lies in mastering every step of the process, it established its very own manufacture in Biel. A year later, the first timepiece produced by its vertically integrated manufacture was unveiled: the One Week. Entirely developed and manufactured in-house and designed with symmetrical harmony in mind, it stood out thanks to its unique movement architecture featuring two barrels that together provide a seven-day power reserve. This milestone marked the beginning of many new calibres and innovations by the Armin Strom manufacture, showcasing their dedication to the science of movement and garnering the admiration and respect of even the most discerning and seasoned collectors.

The new One Week Manufacture Edition completely reimagines this milestone calibre in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.

As Armin Strom founder Serge Michel notes: “Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.”

Sporty yet classy, this model exudes calmness and serenity with its anthracite tones and the symmetrical harmony of its in-house movement.
