Introducing the Armin Strom Gravity Equal Force Ultimate Sapphire Blue

JUNE 25 2025    |    Novelties

We are thrilled to announce the launch of the Armin Strom Gravity Equal Force Ultimate Sapphire Blue, a masterpiece of Swiss horology that combines technical innovation with glacial elegance.

Design & Aesthetics

The watch features a 41 mm stainless steel case and an off-center transparent sapphire crystal dial with a subdial. The main plate, crafted by Kari Voutilainen, showcases a stunning glacial blue guilloché pattern. The color palette of silvery greys and soft blues is inspired by the serene beauty of Swiss glacial lakes. The watch is completed with a blue nubuck leather strap with ice blue stitching.

Movement & Mechanics

Powered by the proprietary Caliber ASB19, the Gravity Equal Force Ultimate Sapphire Blue is the world’s first automatic movement with a patented stop-work declutch mechanism and Geneva cross. This ensures consistent torque and precision across a 72-hour power reserve. The movement is visible through both the front and back sapphire crystals, and features hand-finished components with perlage, Geneva stripes, and circular graining.

Craftsmanship

Each watch is assembled twice to ensure reliability and refinement. Every component is hand-finished in Biel/Bienne, emphasizing traditional techniques and an open-worked design.

Brand Philosophy

Armin Strom celebrates Swiss horological tradition and innovation. Founded in 1967 and revitalized in 2009 by Claude Greisler and Serge Michel, the brand is known for exposing movement mechanics on the dial side. Their motto, “The Science of Movement,” reflects their dedication to precision and craftsmanship.

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.

Moritz Grossmann Presents the New BENU Power Reserve: Tradition Refined

Moritz Grossmann, the independent Saxon manufacture celebrated for its uncompromising craftsmanship and technical ingenuity, introduces the latest evolution of its iconic BENU Power Reserve. This new interpretation embodies the brand’s guiding principle: progress in harmony with tradition.

A Dial That Captures Light and Time
The dial is the face of a watch — a canvas where heritage meets artistry. For the first time, the BENU Power Reserve combines its signature linear power reserve indicator with Azurage decoration. This intricate guilloché pattern of ultra-fine concentric grooves animates the outer chapter ring, creating a captivating interplay of light. The softly textured matte center in shimmering argenté silver contrasts with applied blue numerals and indices, while the brand logo and minute track appear in understated grey.

Completing this refined composition are newly designed hands, handcrafted from steel in the Glashütte atelier. Each hand is meticulously beveled, polished, and then heat-blued using traditional thermal treatment. Their elegant curvature and needle-fine tips exemplify the precision and artistry that define Moritz Grossmann.

The Poetry of Mechanics: Power Reserve Indicator
Mechanical timepieces invite interaction, and the power reserve display is a charming expression of this dialogue. Positioned beneath 12 o’clock, the linear indicator reveals a two-tone bar driven by a differential gear train. When fully wound, the bar appears white; as energy diminishes, a blue segment gradually advances — a subtle yet constant reminder of the living mechanism on the wrist.

Inside the Case: Calibre 100.2
At the heart of the BENU Power Reserve beats the Calibre 100.2, an evolution of the manufacture’s foundational movement. This hand-wound calibre incorporates a differential mechanism for the power reserve display and features the brand’s signature innovations: manual winding with a pusher, a cantilevered balance cock with micrometer screw adjustment, and a separately removable winding module. Through the sapphire crystal back, the movement reveals its artistry — broad Glashütte ribbing, hand-engraved cocks, and raised gold chatons secured by blued screws.

Classic Elegance in Every Detail
The BENU Power Reserve is offered in rose gold and white gold, each with a 41 mm case that reflects the brand’s commitment to timeless proportions. The case surfaces are finely brushed to a soft matte sheen, complemented by a cross-grooved crown and slender lugs. A grey hand-stitched leather strap with blue stitching echoes the dial’s accents, completing a harmonious design that speaks to connoisseurs of understated luxury.

A Legacy Reimagined
Founded in 1854 by visionary watchmaker Moritz Grossmann, the Glashütte tradition was revived in 2008 by master watchmaker Christine Hutter. Today, the manufactory continues to honor its heritage through innovation, artisanal excellence, and a dedication to the finest German craftsmanship.

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.

Introducing the Armin Strom Mirrored Force Resonance Ruby

ARMIN STROM introduces a compelling new interpretation of its most emblematic complication with the debut of the Mirrored Force Resonance Ruby. This creation stands out through its extraordinary natural ruby dial, sourced and crafted by a local Swiss stone artisan. The brand selected only genuine ruby exhibiting depth of colour, fine inclusions, and naturally occurring variations—features that are not flaws but signatures of authenticity, shaped by geological processes over millions of years. As light moves across the dial, subtle tonal shifts appear, infusing the watch with a vibrant mineral presence that contrasts strikingly with the symmetry and modernity of the exposed mechanics.

Beyond its visual impact, this edition embodies ARMIN STROM’s belief that materials must carry meaning. While natural ruby asserts its aesthetic and symbolic presence on the dial, synthetic ruby jewels within the movement fulfil their longstanding horological role of reducing friction and ensuring long-term precision. It is a thoughtful dialogue between nature and engineering, where raw mineral beauty coexists with technical necessity.

At the core of the watch lies the hand-finished Calibre ARF21, a manufacture movement entirely designed and produced in-house. Its defining feature is the brand’s patented Resonance Clutch Spring, which connects two independent regulating systems, enabling the balance wheels to oscillate in harmonic resonance. This phenomenon enhances chronometric stability and is visually showcased by a pusher at 2 o’clock that resets both seconds hands simultaneously—a dramatic demonstration of mechanical synchronicity in action. Operating at 3.5 Hz (25,200 vph) and offering a 48-hour power reserve, the movement transforms a centuries-old scientific principle into contemporary watchmaking mastery.

Craftsmanship remains central to ARMIN STROM’s ethos. The bridges feature hand-polished bevels, black-polished screws, perlage, and circular graining, with Geneva stripes enriching the reverse side. As with every ARMIN STROM timepiece, each watch is assembled twice, ensuring absolute performance and finishing quality. This meticulous approach, combined with the vibrant ruby dial, creates a visually dynamic composition—a living interplay between stone, metal, and motion.

Encased in a 43 mm stainless steel case and fitted with a grey Alcantara strap featuring white stitching, the Mirrored Force Resonance Ruby delivers both presence and refinement. It is not merely a new dial variation, but an artistic expression grounded in horological integrity—an encounter between natural geology and mechanical resonance, distilled into a timepiece of exceptional character.
