Armin Strom Mirrored Force Resonance Green



: Armin Strom’s Manufacture Edition of the Mirrored Force Resonance is now available with a green grenage dial and grey Alcantara strap. With a limited edition of 50 pieces for this watch, Armin Strom continues the design evolution of the horological revolution that is only fully achieved by the independent Biel/Bienne watch manufacture: the harnessing of the near-magical physical phenomenon of resonance.

The open-worked movement is the star of the Armin Strom Mirrored Force Resonance. It is yet another execution proving the fact that Armin Strom is the world’s only watch brand that has fully cracked the code of how to use resonance in a wristwatch. With unique technology, developed and manufactured entirely in-house, the independent watch brand is able to synchronise two movements in one timepiece in order to achieve higher chronometric precision and consistency.

But first, let’s take a look at the new off-centre, green dial featuring a textured grenage finish. The machine-green hue is inspired by some vintage equipment still used alongside contemporary state-of- the-art machines in Armin Strom’s fully integrated manufacture. “We chose this green because it harmonises with the polished and decorated parts of the open-worked movement. And the grenage finish gives a contrast to the polished indexes. This frizzy, kind of frosted surface reflects some light
– but it is not too loud. It doesn’t overwhelm your attention and it shouldn’t compete with the movement,” says Armin Strom’s Master Watchmaker and co-founder, Claude Greisler.

When it comes to the open-worked movement framing the green dial, it is really a showcase for the handmade decoration techniques that are mastered in-house by Armin Strom’s watchmakers. The 3D- shaped balance bridges and all chamfers are hand-polished, and the dial side surfaces are also hand- worked with frosted, perlaged or circular-grained finishes. All parts of the movement – even the invisible ones – are painstakingly decorated with artisanal mastery; a process that sometimes takes 10 times as long as manufacturing the part itself. In addition, the movement is assembled by hand twice to ensure an uncompromising commitment to quality.

Armin Strom is the only watch brand that has fully harnessed the power of resonance, which has mesmerised the world’s best watchmakers since the 17th century. This scientific phenomenon occurs naturally, since two bodies vibrating at a similar frequency automatically strive towards a common frequency. And when two bodies vibrate in resonance – be it radio waves, quantum physics or watchmaking – they are more precise, stronger and more stable and resilient than on their own. Instead of waiting for nature to reach a resonant state between the two balance wheels, Greisler and his team invented the Resonance Clutch Spring, which was first introduced in 2016 after years of research and experimentation. This patented, ingeniously bent spring directly connects the hairsprings, thus keeping the two balance wheels in a perfect resonant state. The swiftly undulating spring and two balance wheels moving to and from each other also make an unexpected and mesmerising dial-side kinetic spectacle.

The Armin Strom Mirrored Force Resonance Manufacture Edition is an extremely rare and complex union of science and Swiss watchmaking of the highest artisanal standards and superlative chronometric performance.

“This watch is all about achieving the highest precision possible. And for me as a watchmaker, hand decoration is very emotional – you can express yourself and add your signature to a watch movement,” said Claude Greisler. “It is not strictly necessary – but thanks to hand decorating and unusual details like the green grenage dial, a watch becomes a piece of art.”


Armin Strom’s patented Resonance Clutch Spring

With its groundbreaking and patented Resonance Clutch Spring, Armin Strom has attained the “holy grail” of watchmaking, by harnessing the physical phenomenon of resonance and thus enabling more regular timekeeping achieved through the synchronization of two balance wheels that oscillate in opposite directions simultaneously. Conceived, developed and produced entirely at the Armin Strom manufacture in Biel, the Resonance Clutch Spring is the result of years of intensive research by Claude Greisler and the manufacture. 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 that uses resonance and remaining in a resonant state longer than any other.

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 than standard mechanical movements. 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.
