Pure Resonance Salmon

CHF 59'000

The purest execution of Armin Strom’s unrivalled resonance wristwatch, The Pure Resonance in stainless steel with a Salmon guilloché dial by Kari Voutilainen’s atelier is the result of years of intensive research by Claude Greisler and the Armin Strom manufacture. It ingeniously incorporates the physical phenomenon of resonance with its patented Resonance Clutch Spring, which directly connects the two hairsprings for the fastest and most regular resonant state ever witnessed in a wristwatch, resulting in exceptional chronometric stability.

A physical phenomenon that has intrigued the greatest watchmakers for centuries yet remains exceedingly rare, the principle of resonance allows for a more regular timekeeping rate by synchronizing two balance wheels that oscillate in opposite directions at the same time. The manufacture’s patented Resonance Clutch Spring is able to reach and remain in a state of resonance faster and for longer than any other resonance system in watchmaking, resulting in a consistent rate that’s more impervious to shocks and positional rate variances.

Armin Strom’s revolutionary resonance mechanism in its purest form, the Pure Resonance combines the patented technology – entirely observable from the dial side – with a classical time display featuring only the hours, minutes and seconds. True to the principle of resonance as applied in watchmaking, the second regulating organ serves to support the main one by coupling into a resonant state for superior rate stability. This is micro-mechanical, kinetic art of the highest order.


Watches incorporating the physical phenomenon are some of the rarest, with only a handful having been invented in the history of watchmaking. Yet none can match the performance of Armin Strom’s patented Resonance Clutch Spring, recognized as the quickest synchronizing and most reliable resonance watch mechanism ever made. It represents a total reimagining of the way resonance can be taken advantage of watchmaking and a truly groundbreaking technical innovation.
