The physical phenomenon of resonance has long been a source of intrigue and fascination for watchmakers. It allows for a more regular timekeeping rate by synchronizing two balance wheels that oscillate in opposite directions at the same time. Even in modern watchmaking, watches incorporating the physical phenomenon are few and far between. In fact, only a handful of watchmakers in the entire history of watchmaking have attempted to harness the potential of this physical phenomenon, with varying levels of success and reproducible reliability.

With its ground-breaking and patented Resonance Clutch Spring, Armin Strom has succeeded where other watchmakers could not. The result of years of intensive research by Claude Greisler and the Armin Strom manufacture, it ingeniously incorporates the physical phenomenon of resonance by directly connecting two hairsprings for the fastest and most regular resonant state ever witnessed in a wristwatch, resulting in exceptional chronometric stability that is much more impervious to shocks and positional rate variances than traditionally built movements.
 

Conceived with the same approach as historical high-precision marine chronometers, where accuracy targets consistency as its sole goal and the device must gain or lose precisely the same number of seconds every single day without variation, the challenge is far greater in a wristwatch that is constantly in motion. In this regard, Armin Strom’s solution can be considered the “holy grail” of marine chronometry.

Armin Strom's revolutionary resonance mechanism executed in its most distilled form, the Pure Resonance, combines the Manufacture’s patented technology – which is entirely visible from the dial side – with a classic time display featuring only the hours, minutes and seconds. Lavishly hand-finished throughout with bevelled and polished edges and wide côtes-de-Genève stripes, this special edition is further embellished with a coppery-rose “salmon” coloured guilloché engraved dial, handcrafted by the celebrated independent and artisanal watchmaker Kari Voutilainen’s atelier using a traditional manual rose-engine lathe for a truly lavish touch. The salmon colour and radiant guilloché pattern add a touch of old-world chronometry to an otherwise cutting-edge piece of creative and highly technical independent watchmaking.
 

The Pure Resonance Salmon special edition will be produced in only five pieces and is available to order as of now.
