Armin Strom is throwing a celebration for the 5 years anniversary for their resonance technology. What better way to celebrate this, than by releasing a rather jaw-dropping Pièce Unique.
The Zeitgeist puts Armin Strom’s patented Resonance Clutch Spring at the center of attention. The technology is showcased in the Zeitgeist by exposing the entire mechanism with an open dial architecture. Armin Strom nicely illustrates the principle behind their patented Resonance Clutch Spring in the video below:
As per Armin Strom ‘resonance relies on the ability of two oscillating mechanisms to transmit vibrational energy between each other, each affecting the other’s rate. When two pendulums or balance wheels are mounted to a common structure, small vibrations – literal waves of energy – are shared through the structure supporting the oscillators. A small force is either added to or subtracted from the opposite oscillator by this energy, averaging their rate by speeding the slower one up and slowing the faster one down. This continues until both rates perfectly synchronize and hold each other at a consistent rate. Based on Breguet’s early experiments, Armin Strom learned that the most effective way to create resonance was to link the two oscillators via the shared suspension. This allows the vibrations to be passed to the opposite balance wheel in the most direct possible way’. Implementing this in their caliber helps with shock resistance, precision and timekeeping consistency.
This technology being the star of the show, the rest of the dial has remained ‘relatively’ muted. Emphasis on relatively! When comparing to for example their previously released Mirrored Force Resonance Special edition Guilloché Dial, this particular release very openly invites you to observe the mechanics at work.
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. All of those mechanics fit in a case no thicker than 11.55mm which is impressive to say the least.
