 ARMIN STROM UNVEILS ENTIRELY NEW DUAL TIME GMT
RESONANCE TIMEPIECE

Biel/Bienne, Switzerland, 29 August 2024: Swiss independent watch brand Armin Strom celebrates the 15th anniversary of its fully-integrated Manufacture by reimagining its most historically significant innovation, the resonance complication, in an entirely new Dual Time GMT Resonance First Edition. The new timepiece is presented in a hotly-anticipated 39-mm case size made in 18-karat white gold and limited to 25 pieces.

Embracing a symmetrical design language with two identical time dials, this First Edition timepiece comes in an elegant 39-mm round 18-karat white gold case. And like all Armin Strom First Editions, it includes a 10-year extended warranty.

Armin Strom once again demonstrates its mastery of ‘the science of movement’ with a finely-proportioned Dual Time Resonance timepiece, delivering unprecedented resilience against disruption of the Resonance phenomenon.

Reflecting on Armin Strom’s new Dual Time GMT Resonance, founder Serge Michel noted:

“Having two completely independent watch movements in a single timepiece creates the logical demand for an iteration that displays two time zones. The success of our first Dual Time inspired us to build a smaller and more elegant Dual Time Resonance watch. To do this, we further developed our concept and arranged the two movements vertically. And we couldn’t be happier with the result.”

Two dial-side kinetic elements unite to form a mesmerizing spectacle

The kinetic spectacle of Resonance is on full display on the dial side of the timepiece. The synchronized motion of two balance wheels operating in a state of Resonance, combined with the hypnotic pulsation of the clutch spring ‘breathing’ as it transmits vibrations between them, offers their owner a mesmerizing spectacle that brings a sense of wonder to the everyday.

Two fully independent time zones

Another valued aspect of the timepiece is its ability to set the two time zones entirely independently. Most dual time zone movements only permit independent adjustment of the hours, with only a few allowing half-hour settings.

However, Armin Strom’s Dual Time GMT Resonance lets users set both the hours and minutes to any desired time on each of two identical dials.

Two movements in one new caliber

The Dual Time GMT Resonance First Edition is powered by the new Armin Strom manufacture caliber ARF22, a manually-wound Resonance movement and the 18th caliber designed and produced in-house under the direction of Claude Greisler, Armin Strom’s co-founder and master watchmaker.

Two independent, symmetrically mirrored oscillators operate in anti-phase to become synchronized mirror images of each other via the natural phenomenon of Resonance. The caliber features two mainspring barrels providing a power reserve of 42 hours, all wound by a single crown at 4 o’clock. Two separate gear trains drive the independent time displays.

The engraved and mirror-polished day/night indicators depicting the sun and moon are mounted on 24-hour wheels directly on the movement. Two crowns positioned on either side of the case allow for the independent setting of each dial.

While many of the most visually-intriguing features are visible on the dial side, the case back further reveals the distinctive symmetrical architecture of the movement. The Dual Time GMT Resonance movement also offers a unique winding experience with a corresponding dial-side animation. The ratchet click system on the dial side of the timepiece provides this animation on the watch face, transforming the winding of the movement into a multi-sensory experience.

Unlike traditional click mechanisms connected to ratchets, the Dual Time GMT Resonance’s three-dimensional ratchet mechanism is connected to a pinion that is positioned between the two barrels to distribute the load more evenly. This two-part system consists of a bottom gear with Breguet teeth fixed to the main plate, and a top element with a spring connected to the axis.

This approach provides more precise engagement and disengagement of the winding mechanism resulting in more consistent performance, more efficient energy transfer, reduced friction and wear on components, smoother operation and better overall durability for the winding system.

Two symmetric dials

The Dual Time GMT Resonance First Edition features two symmetric sky-blue dials, each with a grenage finish.

Armin Strom offers the only Resonance timepieces in active production with dual symmetric time dials.

Two symmetric day/night indicators

Dual engraved and mirror-polished day/night indicators depict the sun and moon to indicate AM/PM for each of the time dials.

Two symmetric crowns

Two crowns, positioned on either side of the case at 4 and 8 o’clock, allow each dial to be independently set.

Two straps

Secured by an 18-karat white gold pin buckle, the Dual Time GMT Resonance First Edition comes with two straps: A matte gray alligator strap with sky-blue stitching and a light gray alligator strap with pearl-gray stitching.

Artisanal craftsmanship

For the First Edition, the dials feature a sky-blue grenage finish, surrounded by black azurage chapter rings set with applied polished baton indexes 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 from steel and designed with a flat surface that is hand-polished to achieve a mirror finish in accordance with the highest standards of traditional haute horlogerie decoration.

The lavish hand-finishing and decoration of this caliber includes hand-polished bevels, screws and countersinks, along with circular graining, perlage and Geneva stripes. The juxtaposition of anthracite and silvery tones further emphasizes the visual depth and dramatic contrast.

What is Resonance?

In watchmaking, a state of Resonance is generated by housing two movements in a single case in such a way that the balance wheels of both movements will naturally influence and regulate each other in real time via the mutual sharing of almost imperceptible vibrations. This sharing enables the twin balance wheels to become fully synchronized and regulate each other in a natural state of Resonance, thereby counteracting the negative effects of gravity and wrist movement on timekeeping. The key benefits of Resonance, in timepieces that can resiliently maintain the phenomenon, are its ability to maintain consistent timekeeping and to maximize timekeeping precision. Chronometric consistency means that a timepiece will gain or lose precisely the same number of seconds every day. Chronometric consistency was historically sought after for hundreds of years in order to solve the “Longitude Problem”, which required consistent timekeeping for more precise calculations of longitude in the context of maritime navigation.

How is Armin Strom’s approach to Resonance different from others?

Armin Strom’s approach to Resonance is fundamentally different from other Resonance timepieces in several key ways. Armin Strom Resonance timepieces utilize a patented, built-for-purpose suspension system known as a “clutch spring”, inspired by Antide Janvier’s Resonance Clock, to act as a vibrational intermediary between the balance wheels. This is in contrast to others who rely on legacy parts of the movement, such as a main-plate, to transmit vibrations.

By virtue of its resiliency against disruption, Armin Strom’s innovative approach can leverage Resonance to proactively prevent oscillation-rate deviations caused by external factors such as wrist motion, gravity and temperature changes rather than merely remediating oscillation-rate errors after-the-fact (when affected balance wheels would otherwise eventually drift back into a state of Resonance). For these reasons, alternative approaches cannot offer the same resilience, predictable chronometric benefits and chronometric consistency as does an Armin Strom Resonance timepiece. This differentiated approach very effectively ensures that the twin balance wheels of an Armin Strom Resonance timepiece will remain synchronized in all positions with resilience against disruption, thereby providing unparalleled chronometric consistency and precision.

As noted by master watchmaker and co-founder Claude Greisler:

“Huygens had his wood beam transmitting the necessary vibrations between his pendulum clocks and Antide Janvier had the shared suspension of his pendulums. Their accomplishments inspired us to develop a built-for-purpose suspension for the reliable transmission of vibrations between the two balance wheels of a Resonance wristwatch in order to achieve the resilience against disruption that Huygens had so ambitiously imagined in the year 1665.”

With an emphasis on transparency, as well as highlighting kinetic elements, the Gravity Equal Force stands out as a technical tour-de-force with an instantly recognisable look – outstanding in form and function, finished by meticulous hand decoration. Now, with the new ‘Purple’ Ultimate Sapphire Edition, Armin Strom is doubling down on integrating vibrant chromatic hues with exceptional mechanics.

Let it reign: Gravity Equal Force Purple

At once regal and electric, the latest edition of the Gravity Equal Force features a colour Armin Strom has never used before. Its base plate boasts a guilloché engraved motif with a barley grain pattern, expertly handcrafted in the atelier of acclaimed independent watchmaker Kari Voutilainen using a traditional rose engine lathe.

The striking purple colour is applied using a 3D PVD process, which reflects a wide spectrum of tones as it shifts with the light. Making this edition even more outstanding, the small off-centred dial is crafted from transparent sapphire crystal, which is reserved exclusively for the Gravity Equal Force’s Ultimate Sapphire Editions. The crowning glory is a light grey nubuck leather strap with purple stitching and keepers. The Gravity Equal Force Ultimate Sapphire Purple is limited to a run of 25 pieces per year.

Automatic: redefined

 The Gravity Equal Force stands out as the first automatic watch endowed with an equal force transmission integrated directly in the mainspring barrel - a patented mechanism by Armin Strom. It provides consistent power transmission to the regulating organ, ensuring unwavering precision throughout the watch’s autonomy. The power reserve indicator forms part of the barrel, which is entirely visible from the dial side, opposite the micro-rotor with a unique click system featuring two springs for better winding efficiency.

Also this latest creation, part of Armin Strom’s perpetual quest for superior chronometric performance, was entirely developed, manufactured and decorated within the walls of the Bienne-based manufacturing site. Like all Armin Strom watches, the Gravity Equal Force Purple’s movement is assembled a first time to ensure it is in perfect working order and that it meets the brand’s exacting decorative standards, then taken apart and assembled a second time when it is ready to be cased in its final form.

Putting the ‘haute’ in ‘horlogerie’

What separates a mere tool from a work of art is craftsmanship. Like a canvas for artistic expression, superlative hand-finishing applied by specialised watchmakers and seasoned artisans can be appreciated throughout the Gravity Equal Force and its many proudly exposed layers and components. Polished bevels (anglage) on the bridges, black polished screws, polished countersinks, perlage and various types of graining, be it straight or circular, as well as Geneva stripes on the three-quarter bridge visible through the case’s back.

One of the Gravity Equal Force’s most distinctive elements is the triplet of dark grey ruthenium-plated bridges that occupy the right-hand portion of the open display. Inspired by the finger-style bridges found in pocket watches, it takes up to an entire day for these bridges to be embellished by hand. First, the undersides are given a matt finish, after which the sides are given a straight-graining finish by carefully sliding them on an abrasive paper to produce continuous, shimmering fine lines.

Then, the inner and outer chamfers of the bridges are bevelled with increasingly fine files and then finished with a flash polish using locally sourced gentian wood to remove even the finest lines. Finally, a straight-graining finish is applied to the top side for ultimate radiance.

Armin Strom : 15 years in the science of movement

In 2008, longtime friends and partners Serge Michel and Claude Greisler took the reins at Armin Strom and founded its very own manufacture in the watchmaking town of Biel in 2009. Just one year later, the duo presented their very first watch with a movement designed and manufactured in-house. Over the following years, Armin Strom would become a truly integrated and self-sufficient manufacture, creating 17 exclusive calibres and developing several world firsts in the domain of watchmaking. In 2016, it introduced the Mirrored Force Resonance, a game-changing resonating dual regulator developed for maximum chronometric precision with a captivating oscillation mechanism on the dial-side of the watch. In 2019, Armin Strom reinvented the automatic watch movement with the Gravity Equal Force, the first automatic watch to feature an equal force transmission mechanism within the barrel that had previously been found only in pocket watches.

ARMIN STROM – One Week – First Edition

 

ARMIN STROM –  One Week – First Edition 2023

 ARMIN STROM UNVEILS THE ONE WEEK FIRST EDITION – THE SUCCESSOR TO ITS FIRST-EVER MANUFACTURE MOVEMENT

Biel/Bienne, Switzerland, 29 August, 2023: More architectural, more open and housed in a new streamlined steel case with an integrated bracelet: Armin Strom completely reimagines one of its most seminal models from the last decade, the One Week, in an all-new form. Debuting as the One Week First Edition limited to 25 examples, it further solidifies Armin Strom’s position as a full-fledged independent manufacture producing unprecedented mechanical marvels.

Maker of movements. The true horology connoisseur’s manufacture. Armin Strom stands out as one of the handful of exclusive independent watch brands that can pride itself in conceiving, developing and building some of the most exceptional mechanical watches around. Back in 2010, the brand unveiled its very first watch called the One Week featuring a movement that was developed and manufactured in house. 

Click, to see the large size. ▶ BIG FOTO  

Equipped with a seven-day power reserve and designed with symmetrical harmony in mind, the One Week would lay the foundation for many of Armin Strom’s groundbreaking developments, placing the brand on the radar of discerning collectors. Now, Armin Strom is revisiting its very first calibre in an all-new design and construction that’s bound to make the One Week a staple model in the brand’s lineup.

Click, to see the large size. ▶ BIG FOTO  

As Armin Strom founder Serge Michel noted, “When we decided to revisit the One Week, we knew from the beginning that we wanted it to be an all-occasions watch: sporty yet sophisticated, intricate yet legible, and filled with immersive little details that even the most demanding collector can appreciate. It was also important for us that the new One Week be instantly recognizable as an Armin Strom by integrating and further refining many of the design elements that have become characteristic of our more recent creations.”

A RADICAL CONSTRUCTION

As devotees of transparent horology, Armin Strom makes it a point to always feature kinetic mechanical elements on the dial side. The One Week First Edition takes this core Armin Strom trait a step further. Completely reengineered and redesigned, the manual-winding movement is as sculptural as it gets. Form, function, aesthetics and ergonomics are all harmoniously brought into the foreground, resulting in a piece of otherwise traditional horology executed in a dynamic, radical way.

“The One Week from 2010 holds a special place for the Armin Strom manufacture as it was the first movement we completely developed and built in-house. We went far beyond simply giving it a facelift, as it is in fact an entirely redesigned and reengineered movement. From the two barrels working in series for better isochronism to the 3D power reserve display and the increased beat rate, the new One Week is definitely a milestone achievement for our team in Biel,” remarked Claude Greisler, master watchmaker and co-founder of the revitalised Armin Strom.

FAR MORE THAN A REMAKE

True to its name and just like its predecessor, the One Week delivers an impressive seven-day power reserve. But that’s where the similarities end. The new manual-winding ARM21 calibre features two mainspring barrels, which work in series to provide consistent levels of energy to the gear train. 

Click, to see the large size. ▶ BIG FOTO  

Held by two finger-style bridges, the barrels are symmetrically arranged on the right portion of the completely open dial. The manual winding ritual takes on a hypnotic choreography, as the motion of two ratchet wheels winding up the two barrels in opposite directions is entirely visible from the dial side.

Click, to see the large size. ▶ BIG FOTO  

One of the most distinctive features of the new One Week is its power reserve indicator. Keeping with the architectural depth of the movement, the power reserve is indicated by a cone system, inspired by pocket watches. This consists of a mirror-polished cone, which is driven by a conical gear on the opposite side of the dial.

Click, to see the large size. ▶ BIG FOTO  

New movement, new beat rate. Another major evolution in the new One Week is the oscillating frequency of the regulating organ. As it is designed as an all-occasions watch that can take on dynamic activities, the beat rate has been increased from 2.5 Hz to 3.5 Hz (25,200 vph). This higher frequency, which offers a more stable chronometric performance, meant that the entire gear train had to be recalculated and reconfigured.

THE PURSUIT OF BALANCE AND DEPTH

Another surprising first for Armin Strom is the placement of the hour and minute hands. Normally, Armin Strom watches feature offset hour and minute hands, either on a subsidiary dial as small hands or slightly off from the centre as large hands. In the One Week, the faceted hour and minute hands filled with Super-LumiNova are perfectly positioned in the centre of the open dial, further enhancing its visual balance.

Click, to see the large size. ▶ BIG FOTO 

In fact, compared to the previous generation of the One Week, which featured a partially open dial to expose the movement, the new One Week was conceived to be much more three-dimensional. It totally foregoes a traditional dial, instead adopting a contemporary architecture, with various movement elements positioned in such a way that they can be explored from many angles. The bridge holding the hands has been designed with a geometric form to rise above the mainplate.

Keeping legibility optimal, the movement is surrounded by a chapter ring set with baton indices filled with Super-LumiNova. The small seconds at 9 o’clock are displayed on a small black dial, emblazoned with the brand’s “AS” logo.

ALL IN THE EXECUTION

Like all Armin Strom creations, from the purest to the most complex, the One Week is a masterclass in haute horlogerie hand-finishing. Straight and circular grained surfaces, chamfered and polished bevels, Geneva-striped plates and polished screws and sinks are clearly applied by expert hands. The One Week First Edition stands out in particular with its cool light blue PVD-coloured mainplate and bridges.

Click, to see the large size. ▶ BIG FOTO  

The One Week’s micromechanical sculpture of a movement is housed in a suitably contemporary case. Crafted in stainless steel, it measures 41 mm in width and only 10.6 mm in height, surprisingly compact proportions for a calibre of such intense depth. Paired with an integrated steel bracelet consisting of “H”-shaped satin-brushed and polished links, the overall design is holistic with an emphasis on ergonomics to make for a perfect everyday wear piece full of mechanical intrigue.

Click, to see the large size. ▶ BIG FOTO  

The One Week First Edition is limited to 25 pieces and will be delivered with an extended warranty period of 10 years, instead of Armin Strom’s usual 5-year warranty. It will also be distinguished from future editions with its light blue PVD coloured mainplate and bridges.
