Armin Strom has unveiled the Dual Time GMT Resonance Manufacture Edition Blue, a limited edition that brings a deep blue treatment to the independent Swiss watchmaker’s distinctive resonance-based dual-time architecture.
Limited to 50 pieces, the new version combines two white textured displays with a blue PVD-coated mainplate and matching details throughout the movement and dial.
The model builds on the Dual Time GMT Resonance that we reviewed in 2025, retaining its fundamental architecture while introducing a new colour treatment that changes the character of both the dial and the movement.
At the centre of the watch is Armin Strom’s manufacture Calibre ARF22, which uses two independent regulating systems connected by the brand’s patented resonance clutch.
The two balance wheels interact continuously, allowing them to oscillate in resonance and creating a visible kinetic element beneath the open architecture of the dial.
Each time zone has its own hours, minutes and day/night indication, making the resonance mechanism part of a practical dual-time display rather than a purely technical feature.
The ARF22 is manually wound and measures 34.15 mm in diameter and 4.92 mm in thickness. It comprises 231 components and 40 jewels, operates at 3.5 Hz, or 25,200 vibrations per hour, and provides a power reserve of 42 hours. The movement is entirely designed, developed and produced in-house.
For this edition, the mainplate and gear-train bridges are finished in blue PVD, creating a strong visual contrast with the two white grené dials.
Their finely grained surfaces are framed by white azurage chapter rings, while blue PVD-coated applied indexes and faceted hands continue the colour theme.
Each dial incorporates a black-polished day/night indicator, with sun rays and a crescent moon, the latter carrying a textured surface.
The blue treatment also extends to the reverse side of the movement. Relief lettering is laser engraved into the mainplate, while polished bevels around the blue surfaces catch the light as the watch moves.
A rhodium-coloured barrel bridge with Côtes de Genève provides another layer of contrast, complemented by black-polished components, circular graining and perlage.
The watch is housed in a 39 mm stainless-steel case measuring 9.05 mm in height, with a lug-to-lug length of 44.50 mm.
Sapphire crystals with anti-reflective treatment are fitted on both sides, and water resistance is rated to 5 ATM. The case is paired with a matte dark blue alligator strap with white stitching and a stainless-steel pin buckle.
The Armin Strom Dual Time GMT Resonance Manufacture Edition Blue, reference ST26-DT.60, is limited to 50 pieces worldwide and is priced at CHF 95,000. arminstrom.com
