t the heart of the Dual Time GMT Resonance Rose Gold is the manual-winding manufacture calibre ARF22, entirely designed, developed and produced in-house. Its defining feature is Armin Strom’s patented resonance clutch, which synchronises two independent regulating systems, allowing both time displays to oscillate in harmony.

The continuous interaction of the two balance wheels creates a dynamic, three-dimensional kinetic display that brings the resonance mechanism to life. Each time zone features its own hours, minutes and day/night indicator, offering intuitive functionality for frequent travellers. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the ARF22 transforms the resonance phenomenon into a functional complication.

Visible through sapphire crystals on both sides, the movement reveals a rich landscape of traditional hand-finishing and mechanical engineering. On the dial side, the engraved and mirror-polished day/night indicators showing the sun and moon located at 6 o’clock of each dial.

Hand-polished bevels, black-polished elements, circular graining and perlage enrich the architecture, while the back side features Côtes de Genève, further enhancing the movement’s refinement. Like all Armin Strom watches, the Dual Time GMT Resonance Rose Gold is assembled twice, ensuring both mechanical precision and flawless finishing.

Limited to 50 pieces worldwide, the Dual Time GMT Resonance Rose Gold stands as a focused expression of Armin Strom’s independent watchmaking.
