Elegant Replica Cheap Swiss made Armin Strom Mirrored Force Resonance Watch

armin strom mirrored force resonance watch

Replica ARMIN STROM Mirrored Force Resonance is an innovative resonating dual regulator watch with a highly original caliber design that is on full display dial side.  Head of watchmaking & technical director Claude Greisler, along with the rest of the Armin Strom team, have really outdone themselves with this new and innovative take on the resonance concept.   Claude Greisler’s idea behind the fake Mirrored Force Resonance was to create an innovative way of improving an old concept, one that is horology’s very reason for being: precision and accuracy.

In horology, resonance is a sophisticated, demanding — and obscure technique. But it is not new — in fact resonance has enchanted many a watchmaker over the past several centuries, including some of horology’s finest such as Abraham-Louis Breguet.  Which makes this new watch from Armin Strom — made entirely in-house and with its symmetrical twin display of seconds bound by a single spring — all the more intriguing. I think its safe to say that the fake Mirrored Force Resonance is now the most complicated timepiece that Armin Strom manufactures.  And no surprise then that this innovation is also patent-pending.

Unlike the majority of watch companies operating today, ARMIN STROM is a full-fledged manufacture with in-house manufacturing capability.   Not surprising then that the resonant Caliber ARF15 (a classically constructed manually wound movement) was conceived, manufactured, assembled, and regulated in-house. In fact it was a necessity: the resonance clutch spring needed to realize the fake Mirrored Force Resonance’s twin display of seconds was so technical that the brand’s team, under the direction of technical director Claude Greisler, was left with no choice other than to create what it needed in house.   The ARF 15 beats at a 3.5 Hertz (25,200 vph) frequency, allowing the observer to really appreciate the patented, resonant regulators in action.  The movement is resolutely modern and finely finished — entirely consistent with the existing Armin Strom caliber design aesthetic.

Like Calibre ARF15, the resonance clutch spring comprises only a traditional horological material: steel.  Greisler and his team spent fully two and a half years perfecting the shape and characteristics of the spring: calculating, optimizing, simulating, testing, and improving again and again until the spring had the optimal, unique form needed to connect  replica ARMIN STROM’s two sets of oscillators, each comprising twin balance wheels and balance springs.  Since the two connected oscillators make their revolutions in opposite directions, which is eminently visible on the dial side of the fake watch, one rotating clockwise and the other counterclockwise, the animated elements look much like they are performing a magic trick. If the 48-hour power reserve has been exhausted and the movement requires a fresh injection of energy through winding, the twin balance wheels need approximately 10 minutes to become synchronous. In case of any outside influence in the form of shock, it takes only a few minutes for the two balances to find their resonant rhythm once again.  This is because it is not the balance wheels that Armin Strom’s technical team has connected using the resonance clutch spring, but rather the balance spring studs, which receive the impulses.  The case band pusher at 2 o’clock resets the luminous twin seconds’ displays to zero, simultaneously resetting the twin balance wheels.

The Concept of Resonance

In the pursuit of horological accuracy, precision, and rate stability resonance has generally involved utilizing two independent mainsprings, gear trains, escapements, and balances, each connected by a rack and pinion to allow fine tuning of the distance between them. Precise adjustment of the distance between the two regulators is necessary to incite resonance, which sees the two balances finding a concurrent rhythm in opposite directions so as to continuously average out errors for maximum accuracy.

One body in motion relays its vibrations to its surroundings. When another body with a similar natural resonant frequency to the first receives these vibrations, it will absorb energy from the first and start vibrating at the same frequency in a sympathetic manner.  The first body acts as the “exciter,” while the second acts as the “resonator.”

The phenomenon of synchronized motion in horology has fascinated watchmakers since the time of Christiaan Huygens (1629-1695). Huygens, inventor of the pendulum clock, was the first to discover the resonance of two separate pendulum clocks, which he logically surmised should keep slightly different time. When hung from a common beam, however, the pendulums of the adjacent clocks synchronized; subsequent researchers confirmed that the common wooden beam coupled the vibrations and created resonance. The two pendulums functioned as one in a synchronous manner. In the eighteenth century, Abraham-Louis Breguet demonstrated his mastery of the phenomenon with his double pendulum resonance clock.

The advantages of resonance are threefold:

A stabilizing effect on timekeeping (advantageous to accuracy).

  1. A conservation of energy (think of a professional cyclist riding in the shadow of another cyclist in a racing situation).
  2. 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.
  3. An outside shock that slows one of the balances down increases the speed of the other one by the same amount; both balances will strive to get back in resonance, thereby averaging and minimizing the effects of the outside influence as they find their rhythm.

To provide an idea of how difficult the horological execution of this concept is, an exhaustive list of watchmakers that have successfully used resonance in an extremely limited number of timepieces includes Antide Janvier (1751-1855), Abraham-Louis Breguet (1747-1823), so few modern clock- and watchmakers that they can likely be counted on one hand.

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.
