Biel/Bienne, Switzerland – March 28, 2025 – Swiss independent watchmaker Armin Strom has once again pushed the boundaries of haute horlogerie with the debut of the Dual Time GMT Resonance – Manufacture Edition Black, a striking timepiece that harmonizes cutting-edge mechanics with refined aesthetics. Encased in stainless steel and paired with a glossy taupe alligator strap, this limited-edition watch exemplifies the brand’s dedication to precision, innovation, and artisanal craftsmanship.
At the heart of this horological marvel lies the ARF22 calibre, Armin Strom’s 18th in-house movement, designed, engineered, and assembled entirely within its Biel/Bienne manufacture. The movement’s standout feature is its dual balance wheels, which oscillate in resonance—a rare phenomenon in watchmaking where two regulators synchronize to enhance accuracy.
Armin Strom’s patented clutch mechanism ensures that the balance wheels remain stable, even against shocks and vibrations, setting a new benchmark in precision timekeeping. This innovation not only marks a milestone in horological history but also elevates the watch to a fusion of art and science.
Beyond its resonance technology, the Dual Time GMT Resonance excels in functionality. It features two independent time displays, each with its own day/night indicator, allowing wearers to track multiple time zones effortlessly. Unlike conventional GMT watches, this model permits adjustment of fractional time differences, making it an ideal companion for travelers navigating time zones that deviate from standard GMT offsets.
The manual-winding ARF22 movement comprises 231 meticulously finished components, operating at 25,200 vibrations per hour (3.5 Hz) and offering a 42-hour power reserve. Every element is hand-decorated, with many visible through the watch’s signature openworked dial, showcasing the intricate mechanics that define Armin Strom’s philosophy: "Every tiny gear deserves to be seen."
The Manufacture Edition Black embraces a sleek, monochromatic aesthetic, with a black grenage dial, azurage chapter rings, and polished rhodium hands ensuring legibility and sophistication. The glossy taupe alligator strap complements the stainless steel case, while the sapphire crystal case back reveals the mesmerizing resonance mechanism in action.
Limited to just 50 pieces, this exclusive timepiece is priced at CHF 95,000, making it a coveted collector’s item for connoisseurs of high watchmaking.
