Armin Strom unveils entirely new DUal Time GMT Resonance timepiece

AUGUST 29 2024    |    Geneva Watch Days 2024

Swiss independent watch brand Armin Strom celebrates the 15th anniversary of its fully-integrated Manufacture by reimagining its most historically significant innovation, the resonance complication, in an entirely new Dual Time GMT Resonance First Edition. The new timepiece is presented in a hotly-anticipated 39-mm case size made in 18-karat white gold and limited to 25 pieces.

Embracing a symmetrical design language with two identical time dials, this First Edition timepiece comes in an elegant 39-mm round 18-karat white gold case. And like all Armin Strom First Editions, it includes a 10-year extended warranty.

Armin Strom once again demonstrates its mastery of ‘the science of movement’ with a finely-proportioned Dual Time Resonance timepiece, delivering unprecedented resilience against disruption of the Resonance phenomenon.

Reflecting on Armin Strom’s new Dual Time GMT Resonance, founder Serge Michel noted: “Having two completely independent watch movements in a single timepiece creates the logical demand for an iteration that displays two time zones. The success of our first Dual Time inspired us to build a smaller and more elegant Dual Time Resonance watch. To do this, we further developed our concept and arranged the two movements vertically. And we couldn’t be happier with the result.”

 

Two dial-side kinetic elements unite to form a mesmerizing spectacle

The kinetic spectacle of Resonance is on full display on the dial side of the timepiece. The synchronized motion of two balance wheels operating in a state of Resonance, combined with the hypnotic pulsation of the clutch spring ‘breathing’ as it transmits vibrations between them, offers their owner a mesmerizing spectacle that brings a sense of wonder to the everyday.

Two fully independent time zones

Another valued aspect of the timepiece is its ability to set the two time zones entirely independently. Most dual time zone movements only permit independent adjustment of the hours, with only a few allowing half-hour settings. However, Armin Strom’s Dual Time GMT Resonance lets users set both the hours and minutes to any desired time on each of two identical dials.

Two movements in one new caliber

The Dual Time GMT Resonance First Edition is powered by the new Armin Strom manufacture caliber ARF22, a manually-wound Resonance movement and the 18th caliber designed and produced in-house under the direction of Claude Greisler, Armin Strom’s co-founder and master watchmaker. Two independent, symmetrically mirrored oscillators operate in anti-phase to become synchronized mirror images of each other via the natural phenomenon of Resonance. The caliber features two mainspring barrels providing a power reserve of 42 hours, all wound by a single crown at 4 o’clock. Two separate gear trains drive the independent time displays. The engraved and mirror-polished day/night indicators depicting the sun and moon are mounted on 24-hour wheels directly on the movement. Two crowns positioned on either side of the case allow for the independent setting of each dial.

While many of the most visually-intriguing features are visible on the dial side, the case back further reveals the distinctive symmetrical architecture of the movement. The Dual Time GMT Resonance movement also offers a unique winding experience with a corresponding dial-side animation. The ratchet click system on the dial side of the timepiece provides this animation on the watch face, transforming the winding of the movement into a multi-sensory experience.

 

 

Unlike traditional click mechanisms connected to ratchets, the Dual Time GMT Resonance’s three-dimensional ratchet mechanism is connected to a pinion that is positioned between the two barrels to distribute the load more evenly. This two-part system consists of a bottom gear with Breguet teeth fixed to the main plate, and a top element with a spring connected to the axis. This approach provides more precise engagement and disengagement of the winding mechanism resulting in more consistent performance, more efficient energy transfer, reduced friction and wear on components, smoother operation and better overall durability for the winding system.

Two symmetric dials

The Dual Time GMT Resonance First Edition features two symmetric sky-blue dials, each with a grenage finish. Armin Strom offers the only Resonance timepieces in active production with dual symmetric time dials.

Two symmetric day/night indicators

Dual engraved and mirror-polished day/night indicators depict the sun and moon to indicate AM/PM for each of the time dials.

Two symmetric crowns

Two crowns, positioned on either side of the case at 4 and 8 o’clock, allow each dial to be independently set.

 

Two straps

Secured by an 18-karat white gold pin buckle, the Dual Time GMT Resonance First Edition comes with two straps: A matte gray alligator strap with sky-blue stitching and a light gray alligator strap with pearl-gray stitching.

Artisanal craftsmanship

For the First Edition, the dials feature a sky-blue grenage finish, surrounded by black azurage chapter rings set with applied polished baton indexes that complement the faceted hands. The engraved and mirror polished day/night indicators depicting the sun and moon are mounted on 24-hour wheels directly on the movement. For the first time, the twin balance bridge is crafted from steel and designed with a flat surface that is hand-polished to achieve a mirror finish in accordance with the highest standards of traditional haute horlogerie decoration.

The lavish hand-finishing and decoration of this caliber includes hand-polished bevels, screws and countersinks, along with circular graining, perlage and Geneva stripes. The juxtaposition of anthracite and silvery tones further emphasizes the visual depth and dramatic contrast.

Armin Strom Unveils the Dual Time GMT Resonance Rose Gold

Armin Strom presents a refined and visually striking evolution of its celebrated Dual Time GMT Resonance collection with the debut of the Dual Time GMT Resonance Rose Gold. Rendered for the first time in a 39 mm 18K rose‑gold case, the timepiece introduces a warm and elegant reinterpretation of the brand’s technically driven design language. Limited to 50 pieces worldwide, this edition pairs the Maison’s signature resonance innovation with a rich new aesthetic personality, blending contemporary elegance with mechanical sophistication.

A New Expression of Design & Craftsmanship
The new Rose Gold edition distinguishes itself through its interplay of warm tones and finely executed textures. The 18K rose‑gold case forms a glowing frame around the black‑gold grenage dial, a surface enriched by depth, contrast, and granular refinement. The dial’s twin layouts—each dedicated to one time zone—are clearly defined by black azurage chapter rings, ensuring intuitive reading while maintaining the balanced symmetry that defines the Resonance line. The rose‑gold‑coloured, faceted and polished hands, together with matching applied indexes, elevate the aesthetic with a luxurious brightness. At six o’clock on each sub‑dial, polished and blackened steel sun-and-moon day/night discs add functional clarity and a poetic visual touch. Completing the ensemble is a matte anthracite alligator strap accented with grey stitching and secured with a matching 18K rose‑gold pin buckle, creating a cohesive, modern, and refined profile.

The Science of Movement: Calibre ARF22
At the heart of the watch lies Armin Strom’s hand‑wound, in‑house Calibre ARF22, a movement defined by the brand’s patented resonance clutch system. This mechanism couples two independent balance wheels and allows them to synchronise through resonance, a natural physical phenomenon that enhances chronometric stability. What might otherwise remain a theoretical curiosity is transformed into a practical complication: each regulating organ governs its own time display, enabling two entirely independent time zones. Each dial also features a corresponding day/night indicator, making the watch particularly intuitive for world travellers. Operating at 3.5 Hz (25,200 vph) and offering a 42‑hour power reserve, the ARF22 movement brings a dynamic, kinetic quality to the dial, where the twin oscillators interact in real time. The aesthetic presentation of the movement reflects haute horlogerie values, with meticulous hand‑polished bevels, black‑polished steel components, circular graining, perlage, and Côtes de Genève on full display through sapphire crystals on both sides. In keeping with Armin Strom tradition, each watch is assembled twice, ensuring uncompromising mechanical integrity and flawless finishing.

The new Dual Time GMT Resonance Rose Gold is offered in a strictly limited edition of 50 pieces

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.

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.
