For the first time, the off-centre dial of Armin Strom's Mirrored Force Resonance carries a sunray guilloché, cut by hand on a rose engine lathe.
Armin Strom today introduces the Mirrored Force Resonance Ice Blue, limited to 15 pieces, its anthracite bridges set beneath the sapphire crystal inside a 43mm steel case.
The ice blue dial catches and reflects light, its new indexes and hands bevelled and polished for extra movement. On the left, two balances oscillate in opposite directions, connected by Armin Strom's patented Resonance Clutch, while twin seconds counters confirm they are in step. A pusher at 2 o'clock resets both counters at once, so the wearer can see the resonance at work.
Claude Greisler, the co-founder who built the calibre, explains the watch in a short video attached to the release. The bridges are hand-bevelled and black-polished, with perlage, Geneva stripes and circular graining, and every watch is assembled twice.
