The Resonance Watch Collection

A Resonance timepiece contains two independent movements whose balance wheels become synchronized due to mutual transfers of vibrational energy between them. The chronometric value of Resonance Synchronization lies in the opportunities it provides for improved timekeeping precision and unparalleled chronometric consistency. Two balance wheels oscillating together in natural synchronized harmony, regulating each other in real-time in a shared state of Resonance, can effectively counteract the negative influence of wrist motion, gravity, temperature changes, and shocks. The result is oscillation-rate stability, torque compensation, predictable chronometric precision and a consistently-maintained kinetic spectacle – but only if Resonance synchronization can be continuously maintained. For centuries, it couldn’t. First in the context of ‘Sea Clocks’ and later in the context of pocket watches and wristwatches, the pursuit of ‘stable’ Resonance remained an elusive goal. Resonance timepieces would intermittently drift in and out of Resonance in response to motion and mild shocks. Some of history’s most iconic watchmakers tried and failed to solve that problem. In fact, that challenge continues to be relevant even for modern timepieces that rely on the mainplate to act as a transmission medium for sharing vibrations between balance wheels. That’s the core watchmaking problem that Armin Strom Resonance timepieces solve.

Co-Founder and Master Watchmaker Claude Greisler spent three years developing our milestone solution with a built-for-purpose oscillation bridge suspension system that we call a ‘Resonance Clutch’; so named because it ‘clutches’ the twin balances of a Resonance timepiece to facilitate the efficient transmission of vibrations. It consistently transfers vibrations between the balance wheels to maintain Resonance Synchronization with unprecedented resiliency against disruption. Our ‘Resonance Clutch’ doesn’t tug, push, pull or coerce the balance wheels. The phenomenon of Resonance is generated and maintained in our Resonance timepieces solely via the consistent transmission and reception of almost imperceptible vibrations. The Centre Suisse d’Electronique et de Microtechnique (CESM) has confirmed and certified that Armin Strom’s approach to Resonance is “True Resonance” while also confirming its superior resiliency against disruption.
