A Star-Filled Sky Over Twin Balance Wheels

Armin Strom reinterprets its Dual Time GMT Resonance with a dial cut from aventurine, a glass material whose flecked, light-catching surface evokes a night sky in motion. The cool celestial dial plays against the warm tones of a rose gold–coloured mainplate and matching hands and indexes, with the architectural symmetry of the resonance movement on full display through sapphire on both sides. At its heart is the in-house manual-winding calibre ARF22 and its patented resonance clutch, which links two independent regulating systems so both balance wheels oscillate in harmony, while each time zone keeps its own hours, minutes, and day/night indicator. Limited to 15 pieces.
