Introducing the Armin Strom Dual Time Resonance Sapphire

The Dual Time Resonance Sapphire by Armin Strom is a horological masterpiece: a chef d’œuvre combining the practicality of two completely independent time indications with the increased precision of two independent movements in resonance. And all that in 360° display within a dazzling transparent sapphire crystal case. While Armin Strom is known for not covering their movements with a dial to highlight the horology within, this sapphire crystal case takes transparency to a whole new dimension. Wearing the Dual Time Resonance Sapphire is like wearing a movement on the wrist, with all of Armin Strom’s meticulous hand finishing and inventive horology on full display. 

“This new Sapphire case sets the perfect stage for the detailed work and passion we put into the Dual Time Resonance. The total transparency does not allow for any mistakes and demands a finish on the highest level, which goes in line with our philosophy,” says Claude Greisler, co-founder of the manufacture.

Armin Strom began research and development into using the phenomenon of resonance in a wristwatch with two main goals: the first that any resonant complication should demonstrably improve timekeeping precision, and the second that people should be able to visually appreciate the phenomenon of resonance as it happens.

The Dual Time Resonance features two independent movements side by side, which even further emphasizes the fact that there are two completely separate movements synchronizing oscillations due to the phenomena of resonance.


The Dual Time Resonance Sapphire demystifies and highlights resonance to the extreme, the crystal-clear sapphire crystal case offering views of the movement from all angles. 

The patented Resonance Clutch Spring – the result of three years of intensive research and development – connects two individual movements arranged side by side, each independently displaying two time zones and each synchronized with the other through resonance for improved chronometric precision.

Independent movements enable the Dual Time Resonance Sapphire to indicate GMT, a second time zone, or function as a timer or countdown. Completing the indications are independent power reserve indicators and a 24-hour indication serving both displays.

The CSEM (Centre Suisse d’Electronique et de Microtechnique) has officially certified Armin Strom’s Resonance Clutch Spring system as being a true system in resonance. Armin Strom’s laboratory testing has revealed gains in precision of 15-20% for two COSC-certified chronometer-level regulated movements placed in resonance.

The Armin Strom Masterpiece 1 Dual Time Resonance Sapphire launches in a scratch-resistant limited edition of 8 pieces.
