Earlier this month, we got to see horological rock star Kari Voutilainen team up with Armin Strom to release a limited run of the latter’s Mirrored Force Resonance. This week at SIHH, however, Armin Strom was back to announce the Pure Resonance, which the brand describes as being focused entirely on “purity and chronometry.”
The Armin Strom Pure Resonance.
Here’s a quick rundown on what a resonance watch is and how it functions.
Watches that utilize resonance are extremely rare due to the significant difficulties in production that go into making them. Resonance timepieces generally involve two independent mainsprings, gear trains, escapements, and balances that are connected by a rack and pinion to allow exact tuning of the distance between each of them. When the two oscillators (all of the above combined) are beating in sync, they are able to find a concurrent rhythm in opposite directions that continuously averages out errors. Basically, the two ?resonating? balances offer higher accuracy, energy conservation, and overall better stability. Close up on the two resonant regulators and resonant clutch spring.
The new Pure Resonance uses two off-centered subdials to display the time compared to the usual three. This was possible only after the Armin Strom team simplified the ARF15 caliber by removing the twin-seconds flyback mechanism. This allowed the placement of a smaller subdial near 7 o’clock that displays seconds using a baton-shaped whit...
