A limited edition of Armin Strom’s remarkable travel watch to celebrate Revolution’s 20th anniversary.
Possibly the most practical complication for travellers, a GMT watch allows you to consult the time in two distinct time zones at a glance. Interpreted by countless brands, Armin Strom’s take on the GMT goes one step further by incorporating the phenomenon of resonance onboard its Dual Time GMT Resonance editions. Offering two independent time zones displayed on two separate dials powered by two independent but synchronised movements, Armin Strom has produced a limited edition of five Dual Time GMT Resonance Tremblage pieces with hand-engraved dials to celebrate Revolution’s 20th anniversary.
The phenomenon of resonance was discovered by Dutch scientist Christiaan Huygens in 1665 when he noticed how two independent pendulums attached to a wooden beam eventually synchronised. Armin Storm’s co-founder and master watchmaker, Claude Greisler, propelled Huygens’ concept into the 21st century with the groundbreaking Mirrored Force Resonance wristwatch of 2016. Greisler’s miniaturised version of the phenomenon, achieved by connecting twin oscillators with his patented resonance clutch spring, is considered a breakthrough in watchmaking.
After three years of work, Armin Strom successfully applied the concept of resonance to a GMT watch. Identical to the 39mm steel model released in 2025 with a slim height of just 9.05mm, the watch features two independent dials controlled by two separate 3.5Hz balance wheels that beat in unison, thanks to the clutch spring at noon. Ruled by impeccable symmetry, the beauty of this watch is that the hours and minutes on each dial can be set independently (each one has its own crown), taking into account unconventional offsets of 30 or 45 minutes.
The watch commissioned by Revolution has been entrusted to master engraver Juliane Gfeller, who has decorated the two gold dials using tremblage (trembling). Rising above the golden baseplate, the solid gold dials are engraved with a micro-etched pattern, producing a surface that seems to be trembling. The hand-engraved day/night indicators at their base are blackened for contrast and mounted directly on the 24-hour wheels. The peripheral chapter ring is snailed and set with polished, faceted indices. Positioned between the dials is the three-dimensional ratchet wheel supported by a circular-grained bridge. The frosted gold baseplate in the background contrasts with the mirror-polished balance bridges and clutch.
The reverse offers a view of the symmetrical and beautifully finished calibre ARF22, an in-house manual-winding movement with twin barrels and a 42-hour power reserve. While the separate crowns are used to adjust the time of the individual dials, the crown on the right is also used for winding. Two openworked black-polished steel bridges, inspired by those found inside marine chronometers, reveal the laser-engraved specifications.
The Dual Time GMT Resonance Tremblage is a limited edition of five pieces. It retails for CHF 100,000 (excl. tax) and is available exclusively on revolutionwatch.com starting from 2 September 2025 at 11PM SGT, 11AM EST or 5PM CET. More details about the model at arminstrom.com.

This right here is the hautest of horology.
If I had to spend 100K on a watch, I would consider this.
It’s not a resonance watch when the balances are connected through a clutch, period.
I see no reason why resonance couldn’t occur through a metal spring?
