ARMIN STROM – Masterpiece 1 Dual Time Resonance Edition



















ARMIN STROMMASTERPIECE 1 Dual Time Resonance Titanium 59 mm Limited Edition


Dual Time Resonance
Masterpiece 1 by Armin Strom

The Dual Time Resonance 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. The Dual Time Resonance launches the Swiss manufacture’s new flagship Masterpiece collection, which highlights the Armin Storm’s extraordinary technical and artistic abilities.

Masterpiece 1 Dual Time Resonance shines a spotlight on Resonance: two independent movements sit side-by-side in a distinctive oval case, their regulators wedded by Armin Strom’s patented Resonance Clutch Spring performing a continually horological two-step between the dual eye-catching counter-oscillating balances.

The Resonance Clutch Spring is the key to Armin Strom’s mastery of resonance, and the was result of three-years of intensive research and development. Two independent movements display two independent time zones — not simply one movement with two displays.

Armin Strom Co-Founder and technical director Claude Greisler explains, “Developing a perpetual calendar or tourbillon would have been far easier than the years we spent calculating and validating the Resonance Clutch Springs, it was uncharted territory

Independent movements enable the Dual Time Resonance to indicate GMT, or a second time zone, as well as a function used as a timer or countdown. Power reserve indicators on each of the hand-guilloche dials and a 24-hour indication at 6 o’clock complete the indications.

While it has been long known that resonance in watch and clock movements with synchronized coupled oscillators improves accuracy by averaging slight differences in the precision of each movement and in wristwatches minimises adverse effects of shocks on precision. Less known is that resonance also conserves energy: vibrational energy that is normally be lost through the supports of the regulator is conserved in the system.

Armin Strom’s laboratory testing has revealed gains in precision of 15-20% for two COSC chronometer-level regulated movements placed in resonance.

“Form follows function” could have been written for the Dual Time Resonance: two movements side by side (rather than stacked vertically) naturally led to the oval-shaped case, while the increased space afforded by the movements in this configuration allowed for two barrels per movement and a longer power reserve. Gazing through the display back at all four barrels winding simultaneously is as mesmerising as the ballet of the dual regulators on the dial.

The Armin Strom Masterpiece 1 Dual Time Resonance launches in a limited edition of 8 pieces in Grade 5 titanium.



Dual Time Resonance: GMT inspiration and development

Masterpiece 1 Dual Time Resonance was developed as a showcase for Armin Strom’s technical and artistic excellence, bringing the phenomena of resonance front and centre.

The resonance clutch spring allows the mysterious force of resonance to be visualized in real time. It’s a visually entertaining complication as well as a technical tour de force; a performance-enhancing mechanism so obvious that you can see it.

Armin Strom did not set out to make a dual time watch; the principal aim was to showcase the resonance movement to the maximum. The movement architecture was a perfect meld of form and function: spreading the two movements apart horizontally in the Dual Time Resonance – compared to the two vertically stacked movements of the Armin Strom Mirrored Force Resonance – meant that a dial on each movement was a logical choice.

And with two time displays, dual time follows naturally. The independent second time display can also function as a countdown indicator or for tracking elapsed time. Two independent (aside from resonance) movements, two independent time displays, one 24-hour indicator, four mainspring barrels, and two conical power reserve indicators.

In the pursuit of horological accuracy, precision, and rate stability, resonance has usually involved using two independent movements connected to allow fine tuning of the distance between them. Until Armin Strom, precise adjustment of the distance between the two regulators has been necessary to incite resonance. However, Armin Strom Resonant Clutch Spring eliminates the necessity for fine tuning the distance and ensures a much more reliable and efficient resonant system.

 When starting out of resonance, the Armin Strom Resonant Clutch Spring can take up to 10 minutes to synchronise the two systems.

The idea of resonance has endured for three centuries for a reason, but that doesn’t mean you can’t improve upon it.

Armin Strom’s patented Resonance Clutch Spring is an innovative way of upgrading an old concept, one that is horology’s very reason for being: precision and accuracy.

Note that the CSEM (Centre Suisse d'Electronique et de Microtechnique) has officially certified Armin Strom’s resonance system based on the clutch spring as being a true system in resonance.



What is resonance?

Any body in motion causes vibrations in its surroundings. When another body with a similar natural resonant frequency to the first receives these vibrations, it absorbs energy from it and starts vibrating at the same frequency in a sympathetic manner.

For example, a trained singer can hold a note causing a tuning fork tuned to the same frequency to vibrate. For the oscillators to be able to synchronize with each other, they have to be closely tuned. A small child trying to synchronize steps with an adult is unlikely to synchronise for more than a few steps as the systems are two dissimilar to resonate.

Imagine yourself pushing a child on a swing: the child and the swing make a natural pendulum, which will have an inherent natural frequency (speed of swing back and forth). If you push at the wrong frequency (too fast or too slow) then you are likely to block the motion and slow the swing down; however, if you push at or near the natural frequency of the swing then you will increase the amplitude (distance the swing moves) of the child/swing system.

In horology, the phenomenon of synchronized motion 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 physics with his double pendulum resonance clock.

An outside shock slowing down one of them increases the speed of the other one by the same amount; but both will strive to get back in resonance, averaging and minimizing the effects of the outside influence as they find their rhythm. What was true for Huygens and Breguet’s clocks is just as true for Armin Strom’s wristwatch.

 The advantages of resonance are threefold: 1) stabilizing effect on timekeeping (better accuracy); 2) conservation of energy (think of a professional cyclist riding in the shadow of another cyclist in a racing situation); and 3) 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 (better accuracy).

While the advantages of resonance have been known for centuries, only a handful of clockmakers and watchmakers have created timepieces deliberately and successfully exploiting the phenomenon of resonance, including Antide Janvier (1751-1855) and Abraham-Louis Breguet (1747-1823). And, now, Armin Strom.

AkriviA – Rexhep Rexhepi Chronometre Contemporain Gold Edition


AkriviARexhep Rexhepi Chronomètre Contemporain Grand Feu Enamel Dial Pink Gold 38mm Limited Edition



Chronomètre Contemporain

The new Chronomètre is available with in white or in black grand feu enamel dial with Art Deco inspired asymmetrical gold or blue lines. These lines frame and segment the Roman numbers in a rhythmic fashion, providing the traditionally handmade grand feu enamel dial with a contemporary touch. The large diameter of the sub-seconds counter at 6 o’clock is a tribute to the officer’s watch of the 1940’s.

The novel case of the Chronomètre Contemporain, creates a fascinating visual tension through the interweaving of symmetrical and asymmetrical forms, as well as concave and convex details visible in the case sides and lugs.

These aspects are enhanced by the alternation of brushed and polished surfaces. Following the purest tradition, the delicate and elongated lugs have been hand-soldered to the case in order to highlight the beauty of this expertly detailed and hand-finished case design.

I have also given special attention to the strap, so that it follows the fine lugs, to allow the design of the case to ‘breathe’ on the wrist. Last but not least, with an eye to modern lifestyles, the case and lugs have been specifically designed to be ergonomic, easy to wear and equally comfortable on large or small wrists.

Movement RR-01

The Chronomètre Contemporain is officially certified by the Besançon Chronometer Observatory and indicates the hours, minutes and seconds.

The movement also features a stop seconds and zero-reset mechanism to allow a precise time setting. As soon as the crown is pulled out to the time setting position, the mechanism implanted stops the balance and instantly returns the second hand to zero.

The new caliber RR-01 embodies all the values I cherish in watchmaking: the attention to every visible and invisible detail, purity, symmetry and functional reduction to the essential. The movement of the Chronomètre Contemporain relates directly to the essence of chronometrical timekeeping instruments.

The winding of this watch will be a sheer pleasure for its owner thanks to the click ratchet inspired by old the pocket watches winding mechanisms.

This provides a smooth winding underlined by a discreet mechanical sound. On the functional side, I have deliberately provided a very long power reserve of 100 hours with only one barrel.

It goes without saying that the entire, in house designed RR-01 movement, is a landmark of precision, fully embellished with handmade traditional finishing techniques such as anglage, black polish and Côtes de Genève. All this represents months of painstaking work requiring the expertise of highly trained experienced watchmakers.
