Dual Time GMT Resonance Manufacture Edition ST26-DT.60

The ultimate indie triumph

Blue has long been part of watchmaking’s vocabulary. On the Armin Strom 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 color, 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.

At the core of this horological achievement is the ARF22 calibre — Armin Strom's 18th manufacture movement, designed, engineered, and built entirely in-house. Featuring two balance wheels that oscillate in resonance, its patented clutch mechanism allows the movement's oscillations to synchronize and regulate one another, ensuring unparalleled accuracy.

Comprising 231 meticulously crafted components, the ARF22 operates at 25,200 vibrations per hour, delivering a 42-hour power reserve. The GMT function of the timepiece features two independent displays, each with its own day/night indicator. Plus, with independently adjustable hour and minute hands, you can set time zones that deviate from GMT by fractional hours—Positioning the Dual Time GMT Resonance Manufacture Edition as the ideal companion, wherever your travels may lead.

But the true essence of this timepiece lies in its mechanical heart. Here, its patented clutch ensures that resonance remains stable, even against everyday shocks and impacts — marking a milestone in horological history and taking timekeeping to the next level of both art and science. The watch’s monochromatic aesthetic and its glossy taupe alligator strap are more than just visual appeal — they serve as a backdrop to the real stars: hundreds of hand-decorated components, many visible through Armin Strom's signature transparent mechanics. 

A physical phenomenon that has intrigued the greatest watchmakers for centuries yet remains exceedingly rare, the principle of resonance allows for a more regular timekeeping rate by synchronizing two balance wheels that oscillate in opposite directions at the same time. The manufacture’s patented Resonance Clutch Spring is able to reach and remain in a state of resonance faster and for longer than any other resonance system in watchmaking, resulting in a consistent rate that’s more impervious to shocks and positional rate variances. 

Watches incorporating the physical phenomenon are some of the rarest, with only a handful having been invented in the history of watchmaking. Yet none can match the performance of Armin Strom’s patented Resonance Clutch Spring, recognized as the quickest synchronizing and most reliable resonance watch mechanism ever made. It represents a total reimagining of the way resonance can be taken advantage of watchmaking and a truly groundbreaking technical innovation.
