With this unique timepiece, independent Swiss manufacture Armin Strom celebrates the fifth anniversary of the brand’s resonance technology.
Armin Strom’s ingenious technology is dramatically showcased in the Zeitgeist by exposing the entire mechanism.
The Armin Strom Resonance Zeitgeist watch elevates the patented, time-tested and scientifically-proven Resonance Clutch Spring in a new caliber, giving the technology a facelift and offering an understated aesthetic profile.
The 43mm case has been crafted from platinum and the movement, created in-house by Armin Strom’s specialists, has been produced in traditional watchmaking metals including German silver, steel, and brass.
The movement is clearly at the center of this distinctive timepiece, which offers minimalist dial components and subtle decoration. Staying true to the concept, the Resonance Clutch Spring and dual balance wheels cantilever off the edge of the movement, drawing the eye to Armin Strom’s technical innovation.
Crafted from a single piece of steel, the Resonance Clutch Spring is designed to transfer energy between both hairsprings and quickly bring the balance wheels into resonance. Armin Strom’s newest generation of resonance is the quickest and most reliable on the market, synchronizing faster than any other watch using resonance.
Thanks to the Resonance Clutch Spring, a flexible suspension connecting the two hairsprings with its balance wheels, all of Armin Strom’s Resonance watches are more resistant to shocks or vibrations.
The Resonance Clutch Spring is made of steel and performs more consistently than high-tech materials like silicon, and it withstands temperature fluctuations well. It also makes the Resonance Clutch Spring future proof by using proven materials and modern methods to increase longevity and aid in serviceability.
Armin Strom’s resonance technology was launched just seven years after Serge Michel and Claude Greisler transformed the brand into a full manufacture.
In that time span, the brand has produced four resonance models, beginning in 2016 with the Mirrored Force Resonance and followed by the Pure Resonance and Dual Time Resonance in 2018 and the world’s first resonance chiming watch in 2019, the Minute Repeater Resonance.
Created to celebrate the fifth anniversary of the brand’s ingenious invention, the one-of-a-kind Zeitgeist is the fifth Armin Strom resonance watch.
