From Theory to Mechanism: Armin Strom’s Approach to Resonance

Claude Greisler, Armin Strom Co-Founder and Master Watchmaker (Biel, Switzerland)

Resonance is one of the most fascinating physical phenomena explored in watchmaking, where two oscillators influence each other and eventually synchronize. Since Christiaan Huygens’ 17th‑century observations with pendulum clocks, watchmakers have sought to harness it in wristwatches.

At the May 2026 lecture of the Horological Society of New York (HSNY), Armin Strom Co-Founder and Master Watchmaker Claude Greisler will share how the brand successfully achieved resonance in 2016 with the calibre ARF15. Central to this innovation is the patented resonance clutch, which links the two hairsprings, allowing them to synchronize quickly and continuously average out rate deviations. Join Greisler as he explores the journey from theory to mechanism and the creation of a modern resonance system.

*Doors open at 5:30 PM ET, lecture to begin at 6 PM ET. RSVP is required.

** The lecture video will be available to members immediately, and to the general public following a two-month delay.
