Following the warm welcome given to its premier Resonance watch in rose gold which launched in 2016, Armin Strom extends the limited edition collection with a new stainless steel variant with a dark blue alligator skin strap. In light of the materials and color, and in keeping with its “elemental” theme, Armin Strom dubs this watch the Armin Strom Mirrored Force Resonance “Water.”
If you are new to this timepiece, let me quickly break it down for you. The Armin Strom “Mirrored Force Resonance” — built around a sophisticated resonating dual regulator system — is the most complicated timepiece that Armin Strom manufactures (and yes they do make tourbillons). The raison d’être of the Mirrored Force Resonance is to display the interesting functionality of the resonant balances while improving the watch’s overall precision. The concept of resonance is basically this: two oscillating bodies in close proximity influence each other and eventually synchronize. The advantages of resonance are three-fold, essentially being 1) advantageous to accuracy, 2) energy efficiency, and 3) rate stabilization (see “Did You Know?” below for more). Of course all this is easier said than done when it comes to watchmaking, which is why “resonance” watches are rarely seen coming out of Switzerland .
And of course, Armin Strom designers opted to place the entire captivating mechanism on full display on the dial side. Dial-side visibility of its calibers and complications is something Armin Strom does as well as anyone, and this watch is no exception.

Limited edition 50 pieces – 54,000 Swiss Francs per
43.4mm x 13mm steel case, manual winding manufacture caliber ARF15
Armin Strom’s caliber ARF 15 has two independent regulation systems that stabilize each other connected by a resonance clutch spring. The two visible, connected oscillators make their revolutions in opposite directions, one rotating clockwise and the other counterclockwise. After winding, the twin balance wheels need approximately 10 minutes to become synchronous. The case band pusher at 2 o’clock resets the luminous twin seconds’ displays to zero, simultaneously resetting the twin balance wheels. Power reserve runs to 48 hours.
Did You Know?
Resonance is a sophisticated and demanding horological technique that has rarely been attempted, let alone mastered in the pursuit of horological accuracy, precision, and rate stability. Christiaan Huygens (1629-1695), inventor of the pendulum clock, was the first to discover the resonance of two separate pendulum clocks, while in the eighteenth century Abraham-Louis Breguet demonstrated his mastery of the phenomenon. Since then, only a handful of watchmakers have attempted to harness the effects of resonance, whose advantages of resonance are threefold: 1. A stabilizing effect on timekeeping (advantageous to accuracy). 2. A conservation of energy (think of a professional cyclist riding in the shadow of another cyclist in a racing situation). 3. A reduction of negative effects on timekeeping accuracy due to outside perturbation such as shock to the balance staff, which in turn keeps the rate more stable and increases precision.
