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

JUNE 25 2024    |    Novelties

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.

A New Pulse of Colour: Armin Strom Unveils the Mirrored Force Resonance Red

Armin Strom has masterfully fused its revolutionary resonance technology with a bold, contemporary aesthetic in the new Mirrored Force Resonance Red. Limited to just 15 pieces worldwide, this rare masterpiece introduces a striking off-centre guilloché dial in vibrant red. By pairing traditional hand-crafted artistry with the brand’s signature open-worked design, this timepiece breathes dynamic new energy into Armin Strom's celebrated dual-balance mechanism, creating a captivating dialogue between classic hand-finishing and cutting-edge mechanical architecture.

The brilliant red dial is hand-crafted on a traditional, manually operated rose engine lathe, engraving a radiating pattern that catches and plays with light in captivating reflections. Encircled by black azuré (蝸形紋) chapter rings and topped with faceted, floating index markers, the dial's layout creates a stark, three-dimensional contrast that maximizes both visual depth and legibility. Housed in a polished 43 mm stainless steel case, the movement's technical architecture is framed by anthracite-coated bridges and paired with a dark grey Alcantara strap—ensuring that the vibrant red dial and the synchronized dance of the resonance mechanism remain the undisputed center of attention.

At the heart of this technical marvel lies the in-house Calibre ARF21, a hand-wound movement that integrates two completely independent movements within a single calibre. Connected via Armin Strom's patented Resonance Clutch, the two opposing balance wheels transfer vibrations to enter and maintain a perfect state of harmonic resonance. This physical synchronization significantly improves chronometric stability and rate consistency over time. To let wearers witness this horological phenomenon in action, a pusher at 2 o'clock activates a flyback mechanism, resetting both independent seconds hands to zero simultaneously so their perfect synchrony can be monitored in real-time.

Every millimeter of the Mirrored Force Resonance Red showcases Armin Strom's uncompromising dedication to haute horology standards, featuring meticulous hand-polished bevels, perlage, circular graining, and mirror-black polished screws. On the reverse side, the main plate features technical inscriptions rendered in three-dimensional relief, rising directly from the metal's surface. As is tradition for the Swiss manufacture, each watch is assembled twice to guarantee absolute precision. For collectors seeking the pinnacle of independent Swiss watchmaking, this 15-piece limited edition represents a perfect harmony of mechanical science and artistic expression.

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.

Chronoswiss Reimagines a Modern Classic with the New Lunar Chronograph Aurora

Chronoswiss introduces the Lunar Chronograph Aurora, a contemporary evolution of one of the brand’s most enduring icons. Since its debut in 1999, the Lunar Chronograph has symbolized Chronoswiss’s ability to blend classical Swiss watchmaking with an independent, expressive spirit. The new Aurora edition carries this legacy forward through a captivating reinterpretation rooted in light, color, and mechanical harmony.

At the heart of the transformation is its fully CVD‑coated dial, which shifts fluidly from deep green to vivid blue as light moves across its surface. Inspired by the ethereal glow of the aurora borealis, this chromatic effect gives the watch a quietly dramatic presence, making every glance feel like a changing atmospheric phenomenon. Balanced chronograph counters, a central analog date, and a poetic moon phase at 3 o’clock come together to form a composition that remains faithful to the model’s architectural heritage while embracing a distinctly modern personality.

The polished stainless‑steel case retains iconic design elements that have defined Chronoswiss for decades, including the onion crown and screwed lugs—details that reinforce the watch’s lineage and mechanical authenticity. Paired with a contemporary grey nubuck leather strap, the Lunar Chronograph Aurora combines classical provenance with renewed visual energy, offering collectors a sophisticated yet forward‑looking chronograph that bridges past and present with effortless elegance.

Mechanical Art Transversed: Moritz Grossmann Reveals the BACKPAGE Tremblage Anniversary Edition

The year 2026 marks a historic milestone for the Moritz Grossmann manufactory in Glashütte, celebrating the 200th birthday of its visionary founder and namesake, born on March 27, 1826. A genius watchmaker, scientist, author, and the initiator of the German Watchmaking School, Grossmann profoundly shaped the craft of horology and the fate of his hometown. Rather than merely duplicating historical concepts, the modern manufactory honors his legacy by blending his cutting-edge philosophy with modern engineering. This dedication to technological perfection and exceptional aesthetics cements its place among the world's elite elite watchmakers.

To commemorate this bicentennial occasion, the brand has unveiled its fourth anniversary special edition: the BACKPAGE Tremblage. Debuting on May 19, 2026, this launch presents an exclusive mechanical showcase for collectors—featuring a massive dial opening that reveals the magnificent inner workings of the movement from the front. Crafted with a luxurious three-part platinum case, the watch conceals a subtle celebratory nod on its reverse side: a balance cock delicately engraved with "1826", the birth year of Moritz Grossmann.

At the heart of this timepiece is the hand-wound manufactory calibre 107.0, a technical tour de force that essentially stands as a mirror image of the signature calibre 100.1. To allow components like the Grossmann balance, hand-engraved balance cock, and the triple-band snailing on the ratchet wheel to be admired on the dial side instead of being hidden on the back, the entire movement architecture had to be re-engineered. An additional wheel integrated between the crown wheel and the ratchet wheel reverses the rotation of the drive train, allowing the mirrored escapement and oscillation system to run perfectly in the correct direction.

The defining aesthetic highlight of this model is its German silver dial face, treated with the historic hand-worked tremblage engraving technique. By meticulously guiding a cutter back and forth in tiny trembling movements, master artisans create a vibrant, finely granulated, and uniform matt texture. The remaining dial elements define the watch's character, offered in either an expressive violet or a captivating "blue meteor" galvanized shade, framing the hour display from 11 to 5 o'clock. Strictly limited to 12 pieces per color variant worldwide, the models are completed with matching hand-annealed steel hands and hand-stitched alligator or kudu leather straps.
