Armin Strom Dual Time GMT Resonance Aventurine

Expanding one of its most technically significant creations, Armin Strom introduces the Dual Time GMT Resonance Aventurine in a compact 39mm stainless steel case. Defined by a shimmering aventurine dial inspired by a star-filled night sky, the latest interpretation brings a celestial dimension to the brand’s signature resonance complication.

First explored by horological pioneers including Christiaan Huygens and Abraham-Louis Breguet, resonance remains one of watchmaking’s most fascinating phenomena. Armin Strom’s modern interpretation is built specifically for the wrist.

Powering the watch is the manual-winding manufacture calibre ARF22, developed entirely in-house. Its patented Resonance Clutch Spring directly synchronizes two independent balance wheels, enhancing chronometric stability and transforming resonance into a practical everyday advantage. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the movement features two fully independent time displays, each with its own hours, minutes, and day/night indicator.

The aventurine dial contrasts against the movement’s warm rose gold-coloured mainplate, while rose gold-coloured hands and applied indexes enhance legibility. Black azurage chapter rings frame the dual displays, complemented by a matte grey alligator strap.

Visible through sapphire crystals on both sides, the open-worked movement showcases hand-polished bevels, black polishing, perlage, circular graining, and Côtes de Genève. Each watch is assembled twice to ensure both mechanical precision and finishing excellence.

Limited to 15 pieces, the Dual Time GMT Resonance Aventurine is a refined expression of Armin Strom’s dedication to ultra-complicated, modern watchmaking.
