For those who look closer.
Blue has long been part of watchmaking’s vocabulary. On the Dual Time GMT Resonance Manufacture Edition Blue, it feels familiar – but never expected. Drawn from classical watchmaking codes, the deep blue carries a subtle retro-chic character, moving from the mainplate to the hands and indexes before continuing onto the dark blue alligator strap. A classic colour, placed where Armin Strom has never taken it before.

The blue finds its counterpoint in two finely grained white dials with white azurage chapter rings. Their subtle texture catches the light while allowing the blue mainplate underneath to come through with greater contrast. The white dials are punctuated by blue PVD coated applied indexes and facetted hands, picking up the colour of the mainplate beneath. The closer the eye gets, the more the contrast reveals.
Two Oscillators. One Resonance.
Armin Strom’s manufacture calibre ARF22 features two independent time displays governed by the physical phenomenon of resonance. Entirely designed, developed and produced in-house, the groundbreaking mechanism incorporates the brand’s patented resonance clutch, enabling its two independent regulating systems to oscillate in resonance with one another. The continuous interaction of the two balance wheels creates a kinetic display with striking three-dimensional depth, offering a direct view of resonance at work. Each time zone features its own hours, minutes and day/night indicator, providing intuitive functionality for frequent travellers. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the ARF22 transforms the phenomenon of resonance into a functional complication.

A different kind of Blue.
Blue changes more than the colour of this calibre. It changes the way its hand-finishing reveals itself. On the dial side, the blue mainplate defines the open-worked architecture, framing the two white dials with their finely grained finish and blue facetted, polished indexes. Each dial incorporates a black-polished day/night indicator depicting sun rays and a crescent moon, the latter engraved with a crater-like texture.

Turning the watch over reveals the reverse of the same mainplate, featuring relief lettering created by laser engraving, together with two matching blue gear-train bridges. The polished bevels bordering the blue PVD mainplate and gear-train bridges appears brighter and more pronounced against the deep blue surfaces, catching the light with every change of angle. What is normally a subtle finishing detail becomes a defining visual feature of the movement. The Côtes de Genève on the rhodium coloured barrel bridge introduce another play of light, their linear finish contrasting with the depth of the surrounding blue. Black-polished elements, circular graining and perlage complete the traditional hand-finishing.
