Armin Strom Unveils Dual-Time Resonance Masterpiece 1 Watch (Prices)

Last week,  Swiss independent watch brand Armin Strom — a master at resonance  — unveiled  the Armin Strom Dual-Time Resonance Masterpiece 1 watch.  The complex timepiece — in both looks and technology — combines two independent movements that display two different time zones with increased  precision thanks to a highly technical watchmaking feat known as resonance.

I wrote about this watch on my Perfect Timing column on, but now I bring a more in-depth study, combining portions of that article with new information and description.

“Armin Strom has become a master at perfecting the concept of Resonance, wherein the natural frequency of each of the two movements in the watch are totally synchronized and that force is constant throughout the entire power reserve of the watch from fully wound to nearly expired.  The brand’s accomplishments are the result of more than three years of extensive research and development into this area.   As a result, Armin Strom has created and built  — totally in house —  a patented Resonance Clutch Spring that keeps both oscillating balances continually moving in counter directions.

While Armin Strom already has an extensive line of Mirrored Force Resonance watches, the new Dual Time Resonance offers GMT (second time zone), and the ability to act as a countdown timer. There is also a power-reserve indication for each of the two chronometer-level regulated movements.  Nestled between the two independent hand-guilloche’ dials is a third dial at 6 o’clock that offers a 24-hour indication.

With much of the important mechanics of this watch (they synchronized coupled dual regulators) visible on the dial side, the  horizontal oval watch offers three-dimensional and technical appeal. The movement is so precise that Armin Strom’s laboratory testing has achieved gains in precision of  15 to 20 percent.  Additionally, each movement has two barrels, affording for a longer power reserve:  110 hours each.  The  Centre Suisse d’Electronique et de Microtechnique (CSEM) testing laboratory in Switzerland, officially certifies the resonance system based on the clutch spring.

Armin Strom Dual Time Resonance Masterpiece 1 watch is crafted in platinum and retails for about $182,000.

So complex is the new manual wind caliber ARF17 that just eight pieces of the Masterpiece 1 Dual Time Resonance will be made in Grade 5 titanium. Each timepiece features a sapphire caseback for viewing of the two movements. Each movement is wound by its own crown, one at  2 o’clock and one at 10 o’clock.  The Armin Strom Dual Time Resonance Masterpiece 1, which measures 59mm in diameters and 43.4mm in height (including lugs), is finished with a black alligator strap.”
