Mirrored Force Resonance Guilloché
After the great success of the inaugural rose gold limited edition, followed by a visually technical stainless steel edition, ARMIN STROM’s most innovative piece to date, the Mirrored Force Resonance, will now be offered to collectors with superb, hand-executed guilloché dials, creating an outstanding synthesis of tradition and innovation – two values dear to the brand.
ARMIN STROM makes an elegant return to traditional craftsmanship, with the introduction of exclusive guilloché dials. Creating a striking contrast with the high-tech movement, the guilloché dials will be available in multiple colors (blue, black, anthracite, red or bi-color), and in several different pattern options (sun-ray, concentric waves or barleycorn), depending on the client’s wishes.
To ensure the best visual result and the highest level of quality, ARMIN STROM has teamed up with Master Watchmaker Kari Voutilainen for the creation of these guilloché dials. They are manufactured in his Môtiers-based workshop, on century-old engine-turning lathes, which can only be controlled by hand. The intricate patterns, obtained by chiseling a smooth metallic plate with extreme precision and care, are true pieces of art, reflective of the craftsmen’s skills and virtuosity.
Two oscillating bodies in close proximity influence each other and eventually synchronize; this is a phenomenon of physics known as resonance. Towards the end of the year 2016, Armin Strom introduced the Mirrored Force Resonance, a resonating dual regulator developed for maximum precision with its whole captivating mechanism on full display dial side.
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:
- A stabilizing effect on timekeeping (advantageous to accuracy).
- A conservation of energy (think of a professional cyclist riding in the shadow of anothercyclist in a racing situation).
- 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.
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. The Mirrored Force Resonance is the most complicated timepiece that Armin Strom manufactures and a patent has been registered.
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 resonance clutch spring provides the watch with a fascinating and patented “animation” of the way it functions. This remains in line with the philosophy of ARMIN STROM as a brand: no nonsense, just good, proprietary mechanics presented in an impeccably finished and interesting way. The resonance clutch spring is exciting in another way, too: it visually proves this timepiece’s resonance.
