Expanding one of its most technically significant creations, Armin Strom introduces a new Dual Time GMT Resonance in a 39mm 18K rose gold case. For the first time, this compact resonance platform is rendered in warm rose gold, offering a richer visual expression of the brand’s signature complication.
First recognized by Galileo Galilei and later explored by Christiaan Huygens, Antide Janvier, and Abraham-Louis Breguet, resonance has long fascinated horologists. Armin Strom’s modern interpretation is built specifically for the wrist.
At its core is the manual-winding manufacture calibre ARF22, developed and produced in-house. Its purpose-built, patented Resonance Clutch Spring directly synchronizes two independent balance wheels rather than relying on vibration transfer through the mainplate. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the system enhances stability and transforms resonance into a practical chronometric solution.
The watch houses two fully independent movements in mirrored symmetry: two crowns, two dials, two balance wheels, two barrels, and two separate gear trains. Each time zone features its own hours, minutes, and engraved day/night indicator, making it ideal for frequent travelers.
Rose gold–colored hands and applied indices contrast against a black gold–toned grenage dial, framed by black azurage chapter rings separating the two displays. Through sapphire crystals on both sides, the movement reveals hand-polished bevels, black polishing, circular graining, perlage, and Côtes de Genève. Each piece is assembled twice to ensure precision and finishing.
Limited to 50 pieces worldwide, the Dual Time GMT Resonance Rose Gold is a focused expression of Armin Strom’s way – cutting-edge modern watchmaking.
