Armin Strom Unveils the Gravity Equal Force Ultimate Sapphire Rose Gold — A Masterpiece of Mechanics and Elegance

JUNE 18 2025    |    Novelties

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.

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.

Greubel Forsey Introduces the Balancier QM: A New Pinnacle of Haute Horlogerie

Independent manufacture Greubel Forsey has unveiled the Balancier QM ($GF09cm$), marking a historic milestone for the workshop by officially naming its highest, most uncompromising hand-finishing standard: Qualité Musée (Museum Quality). While this meticulous level of execution has been quietly embedded into every single timepiece crafted by the Atelier since its founding in 2004, the Balancier QM is the first model to formally carry the designation. Driven forward by a dedicated research wing within the brand’s proprietary EWT (Experimental Watch Technology) Laboratory, this standard mandates that every individual component, whether fully visible through the sapphire crystals or buried deep within the gear train, must hold up as a standalone work of art.

The mechanical architecture of the Balancier QM is a tour de force of in-house micro-engineering and innovation. Most notably, the timepiece features a specialized hairspring manufactured entirely in-house from the raw alloy stage up—a rarity in modern watchmaking accomplished via restored antique machinery. This is paired with an impressive $12.60\text{ mm}$ variable-inertia balance wheel and a cutting-edge bi-level escapement system that utilizes unique convex pallet-jewels, allowing light to softly diffuse through the rubies rather than abruptly reflecting off flat surfaces. Illustrating the immense labor required for the Qualité Musée standard, the steel balance wheel bridge alone requires seven distinct hand-finishing techniques, ranging from flawless mirror barrel polishing to extra-large $0.40\text{ mm}$ hand-polished bevels.

Visually, the timepiece presents an intricately layered, three-dimensional landscape neatly organized within a highly compact 39.60mm white gold case. The movement architecture encourages deep visual exploration; the escapement is nestled into the lowermost depths of the chassis, while the eye naturally ascends past a high-set small seconds sub-dial, flame-blued polished steel hands, and a raised chapter ring. Beneath this upper track, a power-reserve indicator slips mysteriously across a dedicated sector to track the watch's 72-hour chronometric power delivery, sustained by two fast-rotating, series-coupled mainspring barrels. True to Greubel Forsey’s signature underplayed luxury, the words "Qualité Musée" are entirely absent from the dial, hidden instead on a secret internal plate deep inside the movement.

Limited to just 33 exclusive timepieces worldwide, the Balancier QM represents a deliberate strategic pivot for Greubel Forsey toward smaller, more wearable case dimensions without sacrificing an ounce of technical complexity. The manufacture openly acknowledges that achieving this level of structural perfection across all 298 movement parts demands an extraordinary expenditure of time, which will intentionally reduce the company's overall production volume heading into 2027. Looking ahead, the Qualité Musée standard will serve as the foundation for a series of compact releases, including a highly anticipated movement under development at the EWT lab featuring a gear train crafted entirely from solid gold.
