Armin Strom’s Dual Time GMT Resonance gives travellers two time zones, each with its own hours, minutes and day/night indicator, and a new edition sets them on aventurine.
Armin Strom today introduces the Dual Time GMT Resonance Aventurine, limited to 15 pieces. It comes in a 39mm stainless steel case on a dark grey alligator strap.

The brand likens the aventurine dial to a star-filled sky. Rose gold-coloured hands, indexes and mainplate set warm tones against it. Inside is the manual-winding calibre ARF22, designed and produced in-house. Its patented resonance clutch links two independent regulating systems, so both balance wheels oscillate in harmony.
Revitalised in 2009 by watchmaker Claude Greisler and entrepreneur Serge Michel, the Biel/Bienne company assembles every watch twice. On the dial side, the mirror-polished steel balance bridge is hand-bevelled; Côtes de Genève decorate the reverse, seen through a sapphire case back.
Each of the two time zones keeps its own quiet rhythm, in harmony with the other.
