Armin Strom unveils the Mirrored Force Resonance Zeitgeist 1665, a creative interpretation of what a Resonance wristwatch might have looked like centuries ago. This timepiece combines historical horology with modern innovation, celebrating the brand’s milestone achievement of stable and resilient Resonance.

Moritz Grossmann, renowned for its exquisite craftsmanship and precision in watchmaking, proudly announces the launch of the ART EDITION Max Frintrop. This exclusive collection features sixteen unique timepieces, each showcasing a dial crafted from the top layers of renowned German painter Max Frintrop’s studio floor.

A Fusion of Art and Horology

Each dial in this collection captures years of artistic expression, resulting in a mesmerizing display of abstract beauty. The intricate layers of paint, preserved from Frintrop’s studio floor, create a unique and captivating design for each watch.

Craftsmanship and Innovation
At the heart of each timepiece is the calibre 100.1 movement, a testament to Moritz Grossmann’s commitment to quality and precision. Components made from untreated German silver, a hand-engraved 2/3 plate, and the distinctive Grossmann balance are just a few of the features that highlight the exceptional craftsmanship of these watches.

Each watch is engraved with “Unique Piece” on the case back and is available in rose gold or stainless-steel cases. Complemented by different-colored Kudu leather straps, these timepieces are as stylish as they are unique. Max Frintrop’s signature is discreetly engraved on the glass back, adding a personal touch to each piece.

Angelus Unveils Flying Tourbillon Skeleton Titanium in Vivid Orange

Angelus unveils the Flying Tourbillon Skeleton Titanium, Orange Edition, a vivid expression of horological energy and design. Limited to just 25 pieces, this timepiece transforms skeletonised mechanics into a canvas of colour and contrast. The satin-finished titanium case frames a deep black movement, animated by bright orange accents that highlight the time display and extend to three interchangeable straps. The openwork calibre, designed as a series of interlocking circles, adds architectural depth and visual dynamism.

Every detail of this 42.5 mm watch reflects a unique energy. Chromatic energy flows through the orange highlights. Customisable energy is offered by the quick-release strap system, allowing seamless transitions between black alligator leather, orange rubber, and integrated titanium. Light energy emerges from the skeletonised movement, while structural energy is revealed in the layered construction. Graphic energy is embodied in the three-dimensional architecture of the A-310 calibre.

The dial features a floating orange minute track above a black flange, with hour markers crafted for the first time by Angelus in monolithic blocks of Super-LumiNova. These luminous elements ensure legibility in low light and reinforce the watch’s modern aesthetic. At the heart of the case lies a carbon composite chamber, lightweight yet rigid, surrounded by a modular titanium cage that enhances stability and mechanical appeal.

The A-310 calibre showcases Angelus’s signature three-spoke wheels, leading the eye to the flying tourbillon suspended without an upper bridge. Supported by a 160° angled bridge, this asymmetrical design intensifies visual tension and balance. The tourbillon completes a rotation every minute, oscillates at 4 Hz, and offers a 60-hour power reserve. The Flying Tourbillon Skeleton Titanium, Orange Edition embodies the Angelus L.A.B. philosophy—Legacy and Beyond—where technical mastery meets bold design to elevate mechanics into contemporary art.

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.

The Golden Era Begins: Mirrored Force Resonance in Rose Gold

Armin Strom proudly unveils a new expression of its horological mastery with the launch of the Mirrored Force Resonance in 18K Rose Gold. This limited edition marks a significant milestone for the brand’s most iconic timepiece, blending technical innovation with timeless elegance.

A First in Rose Gold

For the first time, Armin Strom’s signature case is crafted from 18K rose gold, offering a warm and luxurious aesthetic. The 43 mm case features alternating brushed and polished finishes, enhancing its sculptural presence. Beneath the sapphire crystal, a bold black off-centre dial showcases a handcrafted sunray guilloché pattern, created using a traditional rose engine lathe. A chapter ring with circular finishing adds depth and texture, while a dark grey Alcantara strap completes the refined look.

Resonance Engineered for Performance

At the heart of this timepiece lies the Caliber ARF21, a manually wound movement that exemplifies Armin Strom’s pioneering work in resonance watchmaking. The patented Resonance Clutch Spring synchronizes two independent balance wheels, enhancing precision and chronometric stability. A pusher at 2 o’clock resets the twin seconds counters, offering a visual demonstration of the resonance mechanism’s accuracy.

Craftsmanship Without Compromise

Every surface of the movement is meticulously hand-finished, visible through sapphire crystals on both sides of the case. Techniques such as hand-beveling, black polishing, perlage, and circular graining highlight Armin Strom’s commitment to haute horology. Each watch is assembled twice to ensure mechanical integrity and flawless finishing.

Limited Edition of 15 Pieces

This exclusive release is limited to just 15 pieces, each priced at CHF 88,000. It represents a rare opportunity to own a timepiece that embodies both technical brilliance and artisanal beauty.
A Statement from Claude Greisler

“The introduction of an 18-karat rose gold case marks a significant milestone for the Mirrored Force Resonance series. This choice of material not only enhances the aesthetic appeal but also underscores our commitment to offering a diverse range of options to our clientele,” said Claude Greisler, Co-Founder and Master Watchmaker at Armin Strom.
