Horological Society of New York to Host Claude Greisler for Resonance Lecture

The captivating principle of resonance, where two oscillating systems interact and synchronize, has long intrigued watchmakers. Since Christiaan Huygens' initial observations in the 17th century with pendulum clocks, the ambition to harness this phenomenon within wristwatches has been a persistent pursuit. Now, a renowned expert is set to illuminate this intricate subject.

Master Watchmaker Claude Greisler to Demystify Resonance at HSNY Event

In May 2026, the esteemed Horological Society of New York (HSNY) will host Claude Greisler, the visionary co-founder and master watchmaker of Armin Strom. Mr. Greisler is poised to deliver an insightful lecture on the brand's groundbreaking success in achieving true resonance in watchmaking with their innovative ARF15 caliber, first introduced in 2016. A key highlight of his presentation will be a deep dive into the patented resonance clutch, a mechanism ingeniously designed to link two hairsprings, enabling them to synchronize swiftly and continually correct rate deviations. Attendees will gain a comprehensive understanding of the intricate process, tracing the evolution from theoretical concepts to the meticulous engineering of a contemporary resonance system.

Claude Greisler, a scion of a distinguished watchmaking lineage, embarked on his formal horological education at a specialized school in Solothurn, Switzerland, followed by advanced studies at the Centre Interrégional de Formation des Montagnes (CIFOM) in Le Locle. His extensive eight-year training encompassed both classical restoration techniques and the intricate design and construction of complex timepieces. Before co-founding ARMIN STROM to actualize his unique vision for watchmaking, he honed his expertise at Christophe Claret, a brand celebrated for its highly complicated movements. Mr. Greisler's unwavering commitment to "transparent mechanics" — a philosophy that not only reveals the aesthetic beauty but also the mechanical genius of each movement — defines his work. At ARMIN STROM, he has spearheaded numerous horological breakthroughs, most notably the Mirrored Force Resonance system, a testament to his dedication to pushing the boundaries of precision, performance, and visual clarity through meticulous finishing and inventive mechanical design.

The eagerly anticipated HSNY lecture is scheduled for May 4, 2026, at the historic General Society Library, nestled in the heart of Midtown Manhattan at 20 West 44th Street, New York, NY, 10036. Admission to this enlightening event is free, though advance tickets are mandatory. Doors will open promptly at 5:30 PM, with the lecture commencing at 6 PM. As with all HSNY lectures, the event is open to the public and will be video-recorded. These recordings are made available to HSNY members immediately, with public access granted after a two-month period.

This event offers a rare opportunity for enthusiasts and professionals alike to engage with a master of horology and gain profound insights into one of watchmaking's most intricate and captivating principles. The lecture promises to be a journey through the historical pursuit of resonance and its modern realization, underscoring the enduring spirit of innovation in the world of fine timepieces. Such discussions contribute significantly to the advancement and appreciation of horological science.
