When we look at the fans, we are relatively used to hearing about technical innovation. Typically, these benefit timekeeping accuracy, power reserve, or impact resistance. However, many of these watches use traditional mechanical motion. Armin Strom’s claim to fame is the mastery of the resonance movement. Today we’re going to outline the technology behind these calibers and make them very special.
Sometimes it can be difficult to understand the complex technical aspects of a wristwatch. That’s why Armin Strom’s resonance motion is so paradoxical. On the one hand, creating movements is extremely complicated and requires a huge breakthrough. On the other hand, once explained, the concept is relatively simple.
What is resonance?
Let’s take this slowly and start by defining “resonance.” Merriam-Webster, a longtime American dictionary, defines it as “a large amplitude vibration of a mechanical or electrical system caused by a relatively small periodic stimulus of the same or roughly the same period as the natural vibration period of the system.” He also states that it is a “condition of adjustment” that generates resonance in a mechanical or electrical system. It may seem rather confusing, but when applied to surveillance, the concept becomes easier, especially in the case of the Arminstrom resonance system.
Essentially, resonant touch is equipped with twin movements. Of course, each one includes a balance wheel. Both can be run independently, but are linked and send vibrations to each other. This transfer synchronizes the two and creates a resonance. It is a natural phenomenon that produces impressive overall accuracy. It can also self-correct the effects of impact, movement and temperature. However, periods of non-resonance pose challenges in timekeeping accuracy, showing a large gap between both movements.
Historically, Watchmakers, including the Abraham-Louis Breguet, used current clock components such as MainPlate and various bridges to transmit vibrations from both barrels. Armin Strom has designed a new method for more than three years for more robust and accurate timekeeping. The brand solved this problem with the invention of a resonant clutch. A thin metal spring with multiple loops is connected to both balance wheels to effectively transfer vibrations from each movement. The advantage is resistance to breakdown over other transmission methods.
Applications of resonance technology
Armin Strom released his first resonance work in 2016. Since then, the brand has miniaturized its movement and added complications. In particular, the company’s small team of watchmakers produces 97% of the components in-house at Beer/Bienne, Swiss. Dual-Time GMT, Minute Repeater, and Time-only models are available, with a twin-second display and flyback sync button. Unlike some very complicated movements, resonance in certain applications can fit a reasonable size of 39mm case.
Very detailed and beautiful
While technological advances like resonance are impressive, the Armin Strom can also make watches beautiful. Of course, the movement is on display. The resonant clutch took the central stage and was machined and polished from a single steel with a width similar to human hair in several places. But what works for the brand is to combine traditional finishes with modern designs. Techniques including hand poling, angling, black polishing, Geneva stripes, straight greying, penetration and more are used to remove all signs of machining. The contrasting finish also creates a visual showcase, distinguishing each component.
Final Thoughts on Arminstrom Resonance
I tend to collect watches that look simple. However, watches like the Armin Strom Dual Time GMT resonance have changed my opinion on more avant-garde watches. These watches combine technical skill with beautiful finishes and cohesive designs. Additionally, the brand continues to develop resonant calibur, making them smaller and thinner. The movement itself is surprising, indicating that there is still room for innovation in this traditional industry. If you have never seen any of these watches in person, we highly recommend doing so. Simply watching the movement is an engaging experience.
