Mirrored Force Resonance Manufacture Edition Blue

With its patented Resonance Clutch Spring, Armin Strom achieved what many consider the holy grail of mechanical watchmaking: stable, real-world resonance. Developed and produced entirely in Biel, this single-piece steel clutch spring transfers energy between two hairsprings, synchronizing twin balance wheels oscillating in opposite directions for more regular and consistent timekeeping.

This Manufacture Edition Blue showcases the manually wound Calibre ARF21 inside a refined 43 mm stainless steel case. Twin seconds counters offer a visual confirmation of resonance in action, while the off-centre dark blue dial — finished with a grenage centre and satin-brushed chapter ring — balances technical depth with restrained elegance. Designed for daily reliability, this generation of resonance is faster to synchronize and remains stable longer than any previous resonance system.

Limited to just 50 pieces, the Mirrored Force Resonance Manufacture Edition Blue is a clear expression of Armin Strom’s pursuit of precision, resilience, and mechanical honesty.
