Mirrored Force Resonance Manufacture Edition Green

A micro-mechanical revolution, the Mirrored Force Resonance in steel with a green dial is the result of years of intensive research by Claude Greisler and the Arm in Strom manufacture in incorporating the physical phenomenon of resonance in watchmaking for the ultimate chronometric stability. It works by means of the patented Resonance Clutch Spring, which directly connects the two hairsprings for the fastest and most regular resonant state ever witnessed in a wristwatch.
