DUAL TIME GMT Resonance First Edition

CHF 115'000

The wait is over. Armin Strom celebrates the 15th anniversary of our fully-integrated Manufacture by reimagining our most historically-important innovation in a slim 39mm white gold case. The Dual-Time Resonance GMT showcases our uniquely resilient approach to harnessing the Resonance phenomenon as well as our longstanding commitment to extraordinary hand-finishing; culminating in a dial-side kinetic spectacle that’s unlike anything else in contemporary watchmaking.

Functionally, the Dual-Time Resonance GMT displays two independent time zones, with indications of hours and minutes for each; while also supporting time zones that deviate from GMT by fractions of an hour. Day/Night indicators provide relevant AM/PM context for each time zone. The Dual-Time Resonance GMT First Edition includes two compelling strap options and is offered with a ten year warranty. Limited to 25 pieces.

A DIFFERENTIATED APPROACH

The resonance phenomenon is generated by housing two movements in a single case in such a way that the balance wheels of both movements naturally influence and regulate each other by sharing vibrations. As these balance wheels oscillate in anti-phase, they gradually become synchronized mirror images of each other – and ultimately regulate each other’s motion via the phenomenon of resonance. Watchmaking’s long fascination with resonance, which began in the year 1655, was based on the early recognition that it could eventually be leveraged to achieve both chronometric consistency and timekeeping precision.

The challenge of resonance, however, has always been to overcome its fragility and achieve resilience against the disruptive effects of gravity, temperature changes, and motion on timepiece oscillation rates. To that end, the Dual Time GMT Resonance offers a differentiated, patented, and purpose-built suspension system called a clutch spring, which maintains the resonance phenomenon with unparalleled resilience against disruption. Inspired by Antide Janvier’s Resonance Clock, which he called a “Double-Dial Regulator,” the clutch spring acts as an efficient vibrational intermediary between the Dual Time GMT Resonance’s twin balance wheels. The clutch spring’s consistent sharing of vibrations enables balance wheel synchronization to be maintained in adverse conditions (such as the rocking of a ship or the motion and the ever-changing positions of the human wrist). Operating in what scientists call a “shared mode of motion,” the balance wheels are empowered by their resilient synchronization to consistently prevent the oscillation-rate deviations that would ordinarily occur in response to real-world stimuli. The phenomenon of resonance is generated and maintained solely via the consistent transmission and reception of shared vibrations.

Armin Strom’s resonance is “true resonance” and is certified as such by CSEM, the Swiss Center for Electronics and Microtechnology.

A LONG HISTORY CULMINATING IN ULTIMATE TRIUMPH

For over 350 years, some of history’s most iconic watchmakers pursued the elusive ambition of maintaining resilient resonance in a timepiece. They hoped to improve timekeeping precision and achieve the milestone of “chronometric consistency” (the gain or loss of precisely the same number of seconds every day). They were motivated by the possibility of leveraging these chronometric benefits to improve the accuracy of longitude calculations − and very likely also by the promises of great wealth offered by various European governments who sought a solution for improved maritime navigation. Unfortunately, resonance proved to be too delicate a phenomenon to be harnessed effectively at the time as it was easily disrupted in real-world environments. As Sir Issac Newton advised the British Parliament in 1714, “Such a watch hath not yet been made.”

The horological journey to achieve chronometric consistency and timekeeping precision via resilient resonance was only completed in 2016 with the release of our first resonance timepiece. That milestone achievement is fully maintained in this smaller, thinner, and more elegantly proportioned Dual Time GMT Resonance.

ARTISANAL CRAFTSMANSHIP 

The twin dials of this timepiece feature a sky-blue grenage finish, surrounded by black azurage chapter rings set with applied polished baton indices that complement the faceted hands. The engraved and mirror-polished day/night indicators depicting the sun and moon are mounted on 24-hour wheels directly on the movement. For the first time, the twin balance bridge is crafted in steel with a flat surface that is hand-polished to achieve a mirror finish. The lavish hand-finishing and decoration of this calibre includes hand-polished bevels, screws, and countersinks along with circular graining, perlage, and Geneva stripes. The Dual Time GMT Resonance offers a unique winding experience, with a corresponding dial-side animation of its three-dimensional ratchet wheel at 6 o’clock.
