Armin Strom Dual Time GMT Resonance Manufacture Edition Blue: 50 Pieces

Early Impressions

• Blue PVD coating covers the entire ARF22 mainplate — carrying through to the hands, indexes, gear-train bridges and matte dark blue alligator strap with white stitching, making colour the organising principle of the whole composition.
• Reference ST26-DT.60 is a 50-piece worldwide limited edition, priced at CHF 95,000.
• Two independent regulating systems, linked by Armin Strom’s patented resonance clutch, each govern their own hours, minutes and day/night indicator — visible directly through the open-worked dial.
• The 39 mm stainless steel case houses calibre ARF22, manually wound, running at 3.5 Hz with a 42-hour power reserve.

Reference ST26-DT.60 arrived under embargo on 31 August 2026, and the first thing it communicates is confidence in restraint. Armin Strom has used blue before across the Dual Time GMT Resonance Aventurine and the Mirrored Force Resonance Ruby lines, but never with this particular chromatic discipline: a single colour, drawn consistently from mainplate to buckle, with white providing the only break. On the wrist, the effect is quieter than the specifications suggest, and more considered than any purely aesthetic reading of the colour choice would imply.

For GCC collectors accustomed to evaluating independent Swiss manufacture pieces against the output of much larger ateliers, the Edition Blue invites precisely the scrutiny the press release headline demands. Blue, here, is not decoration — it is structure.

Design & Mechanics

The open-worked architecture of calibre ARF22 means the blue PVD mainplate is not hidden behind a conventional dial; it defines the visual field. Two white grenage dials with azurage chapter rings occupy the upper portion of the movement face, their finely grained surface catching light in a way that amplifies, rather than masks, the blue beneath. Applied indexes in blue PVD-coated polished steel and facetted hands in the same treatment pick up the mainplate colour, creating a chromatic loop that tightens as the viewing angle changes.

Each dial carries a black-polished day/night indicator depicting sun rays and a crescent moon — the latter engraved with a crater-like texture that rewards magnification. Turning the case over reveals the reverse of the same mainplate, where laser-engraved relief lettering sits alongside two matching blue gear-train bridges. The polished bevels bordering the blue PVD surfaces become far more pronounced against the deep colour, catching light with every movement of the wrist. Côtes de Genève on the rhodium-coloured barrel bridge introduce a secondary texture, its linear finish contrasting with the depth of surrounding blue. Black-polished elements, circular graining and perlage complete the traditional hand-finishing across 231 components.

Movement & Materials

Calibre ARF22 is entirely designed, developed and produced in Biel/Bienne. Its defining characteristic is the patented resonance clutch: two independent regulating systems — each with its own balance wheel — oscillate in synchrony through physical resonance rather than mechanical linkage. The continuous interaction produces a kinetic display with three-dimensional depth; both balance wheels are visible from the dial side, their simultaneous motion giving the open-worked movement a rhythm that no single-oscillator construction can replicate.

Operating frequency is 3.5 Hz (25,200 vph), with a 42-hour power reserve from manual winding. Each time zone is assigned its own hours, minutes and day/night indicator — a practical GMT architecture that does not sacrifice complication legibility for visual theatrics. The 39.00 mm stainless steel case stands 9.05 mm tall with a lug-to-lug of 44.50 mm, remaining genuinely wearable for a two-oscillator manufacture piece. Water resistance is rated at 5 ATM, with sapphire crystal front and back, both anti-reflective treated.

On the Wrist

At 39 mm, the Dual Time GMT Resonance sits closer to a dress watch in footprint than to the broad-cased sports references that dominate GCC collector conversations. The matte dark blue alligator strap with white stitching and stainless steel pin buckle continues the chromatic logic of the movement all the way to the wrist — a rare instance where strap and calibre share a genuinely unified colour treatment rather than a merely compatible one.

For frequent travellers between Gulf cities and European financial centres, the dual-zone architecture with independent day/night indicators offers direct, unambiguous reading — no mental arithmetic required between Dubai and Geneva. The Tribute² Aurum sits above this reference in the Armin Strom hierarchy in terms of material, but the Edition Blue positions itself as the more wearable proposition within the resonance family.

Where It Sits in the Armin Strom Line-Up

Armin Strom has used its resonance platform across several chromatic editions. The Dual Time GMT Resonance Aventurine applied a mineral-inflected colour approach; the Mirrored Force Resonance Ruby pushed precious stone into the movement architecture. The Edition Blue takes a different position: classical watchmaking colour, applied with industrial consistency across every component that touches the eye. At CHF 95,000 across 50 pieces, it occupies the upper tier of independent Swiss manufacture GMT watches — comparable in price to complicated pieces from far larger ateliers, but offered in a quantity that makes secondary-market scarcity likely.

For GCC collectors building across Armin Strom’s resonance editions, the Edition Blue reads as the most wearable and arguably the most formally versatile of the series. Visit Armin Strom for authorised retailer details in the region.
