To celebrate the fifth anniversary of the Armin Strom Resonance watches, the manufacture from Biel/Bienne presents this new unique piece named “Zeitgeist” —which translates into a collective outlook of people or culture at a specific point in time. The new Armin Strom Zeitgeist Unique Piece is the fifth piece in the Armin Strom Resonance saga that started with the Mirrored Force Resonance watch. The Zeitgeist Unique Piece marks the next chapter for resonance watches.

Armin Strom’s ingenious technology is dramatically showcased in the Zeitgeist by exposing the entire mechanism. The Zeitgeist 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.

Armin Strom began working with resonance by learning from what Christiaan Huygens, Abraham-Louis Breguet, and Antide Janvier had already discovered centuries ago: resonance is incredibly valuable for consistency, employing scientific principles to regulate rate precision over time. The old masters were engineers who sought to create the most precise and consistent timekeepers for use as scientific instruments, performing tests to discover new principles. The phenomenon of resonance on oscillating systems was successfully applied to horology but has remained very rare due to the difficulty of its implementation. Armin Strom’s Resonance Clutch Spring makes this possible. 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. Precision and consistency are, of course, the ultimate goals of mechanical watchmaking, and resonance plays a crucial role in helping these amazing watches keep time consistently over days, weeks, and months. Armin Strom’s goal is a watch that the owner knows will tell the time consistently, day in and day out.

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. Simply put, Zeitgeist is built to last.

For this unique piece, the 43 mm 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.

“We decided to create something unique for this fifth anniversary: a work of art that honors our resonance technology and pays tribute to our roots in skeletonization. Zeitgeist’s movement was painstakingly produced, piece by piece, clearly emphasizes the resonance mechanism. This has never been done before so we’re all very excited” says Claude Greisler, Armin Strom’s Co-Founder and Master Watchmaker.

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.

As Armin Strom Founder Serge Michel points out, “Zeitgeist honors our resonance technology, which plays a very important part in the history and the future of our brand. It stands for our belief in the evolution of watchmaking and it clearly marks the next chapter in resonance for our manufacture.”

Cased in platinum, the Armin Strom Zeitgeist features an 18K white gold “vernis laqué poli” dial with open-worked hands in stainless steel.

This fifth example of the Armin Strom Resonance watches is powered by Armin Strom manufacture calibre ARF21_ZG. This manual movement features a patented resonance clutch spring, two mainspring barrels and regulating system with two independent regulation systems connected by a resonance clutch spring, and features a twin second flyback pusher. This 39-jewel movement is composed of 260 parts and provides a power reserve of 80 hours when fully wound.

The Armin Strom Zeitgeist Unique Piece is delivered on a black alligator leather strap with a double folding clasp.
