The idea behind the Mirrored Force Resonance was to create an innovative way of improving an old concept, one that is horology’s very reason for being: precision and accuracy.
The resonance clutch spring needed to realize the Mirrored Force Resonance’s twin display of seconds was so technical that the brand’s team, under the direction of technical director Claude Greisler, was left with no choice other than to create what it needed in house. Like Calibre ARF15, the resonance clutch spring comprises only a traditional horological material: steel. Greisler and his team spent fully three years perfecting the shape and characteristics of the spring: calculating, optimizing, simulating, testing, and improving again and again until the spring had the optimal, unique form needed to connect the two sets of oscillators, each comprising twin balance wheels and balance springs.
Resonance is a sophisticated and demanding horological technique that has rarely been attempted, let alone mastered. In the pursuit of horological accuracy, precision, and rate stability resonance has generally involved utilizing two independent mainsprings, gear trains, escapements, and balances, each connected by a rack and pinion to allow fine tuning of the distance between them. Precise adjustment of the distance between the two regulators is necessary to incite resonance, which sees the two balances finding a concurrent rhythm in opposite directions so as to continuously average out errors for maximum accuracy.
