Dual Time GMT Resonance Manufacture Edition

When two oscillators beat as one.

At the core of this horological achievement is the ARF22 calibre—our 18th movement, designed, engineered, and built entirely within our Manufacture. Featuring two balance wheels that oscillate in resonance, our patented clutch mechanism allows their vibrations 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, our 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 our signature transparent mechanics. At Armin Strom, we believe every tiny gear deserves to be seen, as they each play a vital part in the precision and beauty of the movement.
