A micro-mechanical breakthrough, the Mirrored Force Resonance represents the culmination of years of intensive research by Claude Greisler and the Armin Strom manufacture, successfully mastering the physical phenomenon of resonance to achieve remarkable chronometric stability. At the heart of this innovation lies the patented Resonance Clutch Spring, an ingenious mechanism that directly connects the two hairsprings and enables the establishment of a stable and highly efficient resonant state within a wristwatch.

Presented beneath an elevated sapphire crystal 'glass box', the movement reveals an exceptional sense of depth and architectural transparency. The openworked construction was further refined through redesigned balance bridges, creating greater visual openness and perfectly balancing the display between the off-centre dial and the two synchronised regulating organs. A pusher positioned at 2 o’clock allows the wearer to simultaneously reset the twin seconds indications, rotating in mirrored clockwise and counterclockwise directions, providing a visual demonstration of the resonance state.

The technical and artistic sophistication of the movement continues on the reverse. The present timepiece bears the engraving 'FINAL EDITION', commemorating the final production of this celebrated model. Constructed around two entirely independent gear trains and energy sources, the calibre displays remarkable symmetry, with bridges and wheels arranged in mirrored formation to emphasise both mechanical logic and visual harmony.

Machined from a single piece of steel, the Resonance Clutch Spring plays a critical role in transferring energy between the two oscillators, allowing rapid synchronisation and sustained resonance. Compared with traditional resonance systems, this latest generation offers faster synchronisation, enhanced stability, and improved resistance to shocks and external disturbances through the direct mechanical coupling of the regulating organs. The result is one of the most advanced and efficient resonance mechanisms developed in contemporary watchmaking.
