Armin Strom Orbit – First Edition

Independent Swiss watchmaker Armin Strom presents Orbit, a brand-new mechanical timepiece featuring the world’s first date function displayed on a bezel.

This new creation features a highly legible date driven by a column-wheel that can be activated and deactivated with the push of a button. The “Orbit” first edition is limited to 25 pieces.

Armin Strom Orbit - First Edition

With its System 78 collection, the independent Armin Strom manufacture seeks to create new and innovative expressions of fine watchmaking, with ingenious and practical world firsts executed in an unmistakable language of design. The latest addition to the line, the Orbit first edition, reinterprets the date – one of the most common watchmaking functions – by combining several complications in one in a totally new way.

Armin Strom Orbit - First Edition

The Orbit’s most outstanding feature is its unprecedented and playfully imaginative date function. Entirely conceived, developed and built by the Armin Strom manufacture, the unique complication has been dubbed the “Column-Wheel Date”.

As its name implies, the column-wheel drives the date mechanism, which is visible from the dial side. This system, typically found in chronograph mechanisms, enhances the date indicator’s stability and performance while also providing a satisfying and reassuring tactile experience when engaging and disengaging the date function.

Armin Strom Orbit - First Edition

The date is indicated on the bezel by a large central hand with a red “A” tip for Armin. The days of the month – 1 through 31 – are engraved in white around the circumference of the polished black ceramic bezel for a high-contrast and instantly readable effect.

The date hand essentially has two modes: stationary and active.

When the date hand is in the stationary mode, it is essentially “off” and remains in its fixed position pointing at 12 o’clock, leaving the off-centred dial unobstructed. Using the pusher on the left side of the case, the date hand is engaged and jumps to point at the correct date. In this mode, the date automatically advances once a day, at midnight. With another push of the button, the hand returns to its stationary position, with a mechanical memory allowing it to jump back to the correct date when required by the wearer.

Armin Strom Orbit - First Edition

The retrograde mechanism allows the date hand to jump back from 31 to 1, avoiding any confusion with the hand’s position when in the stationary mode. The date can be rapidly set using a corrector button on the 8 o’clock position of the case or can be advanced manually via the crown by advancing the time.

Based on the development of the Gravity Equal Force that was unveiled in 2019 as the world’s first automatic watch with equal force transmission, the Orbit’s movement delivers consistent power to the balance, with a power reserve of 72 hours. Its “stop-work” mechanism within the barrel prevents the mainspring from fully unwinding, thus leveraging only the part of the mainspring’s unwinding process that can deliver power most consistently.

Armin Strom Orbit - First Edition

And true to the manufacture’s unwavering commitment to offering true haute-horology craftsmanship across its entire collection, the movement is fully hand-finished and decorated with features such as chamfered and polished edges, polished chatons and perlage graining.

Armin Strom Orbit - First Edition

Housed in a 43.4 mm stainless-steel case paired with an integrated steel bracelet, the design of the Orbit allows for the technical prowess of the unique column-wheel date complication as well as the micro-rotor mechanism and equal force barrel to take centre stage, all while adding a sporty allure.

Armin Strom Orbit - First Edition

The bezel immediately conveys a sense of performance and utility while remaining visually sleek. Perfectly smooth to the touch yet highly resistant to scratches, the bezel framing the micro-mechanical spectacle within is crafted in ultra-hard black ceramic, which is engraved and painted with the dates.

The offset dial is a black-gold colour, indicating the hours and minutes as well as the seconds on a separate counter. The numerals, hour markers and the hour and minute hands are filled with off-white Super-LumiNova® for optimal legibility in the dark. A rare feat for most watch manufactures, the steel hands are manufactured by Armin Strom and, like all the visible parts of the movement, are meticulously hand-finished in-house.

Armin Strom Orbit - First Edition

This first iteration of Orbit is further distinguished by the fact that the three bridges– the barrel, the micro-rotor and winding bridges– are specially coated in black gold.

This timepiece is offered with a 10-year year warranty–twice as long as Armin Strom’s standard warranty.

Armin Strom Tribute 1 California

A new addition to Armin Strom’s System 78 Collection, the Tribute 1 California watch features a California-style dial created in a choice of five fumé colours that offer a striking contrast to the black guilloché plate. Each colour option has been produced in a limited edition of five pieces.

The newest interpretation of the Armin Strom Tribute 1, the brand’s popular modern dress watch, takes its name from the so-called California dial, which is distinguished by its alternating Roman and Arabic numerals. The dial, which is offered in five different colours, also features bar markers and a railway track minute ring.

Armin Strom Tribute 1 California

Once again, Armin Strom’s Master Watchmaker Claude Greisler has revealed his passion for his industry’s heritage: the California dial design, which is a favourite among watch aficionados, dates back to the 1930s and with its distinct presentation on the coloured dials, it offers each proud owner a timepiece of distinction and a touch of exclusivity. The visibility of the barrel on the dial makes the Tribute 1 California resolutely modern while the California dial gives it a pleasing vintage flair.

Armin Strom Tribute 1 California

With its Tribute 1 California, the independent Swiss luxury brand Armin Strom has introduced five compelling new takes on the classic manually-wound dress watch. With dials in five different colours – blue, light blue, green, burgundy and black – it is available in editions limited to five per colour, meaning that the total edition size for the Tribute 1 California is 25.

Armin Strom Tribute 1 California

The “fumé” dials in each of the colours incorporate a sunburst pattern with a gradient effect: towards the centre of the dial, the colour is quite light and becomes deeper and darker towards the outer edge. The effect in all five colours is at once understated and dramatic and is complemented by the dial’s contrast to the black guilloché plate.

Armin Strom Tribute 1 California

The black guilloché plate was created by hand by Finnish watchmaker and close friend of the brand, Kari Voutilainen. The movement and hands, designed and manufactured in-house at Armin Strom, feature exceptional hand finishing.

The barrel, which is prominently displayed on the dial side of the watch, is clearly the star of the movement. It has been meticulously hand-decorated, an extremely time-consuming process, and is engraved with the words “100 HOURS OF POWER RESERVE”, a testimony to that impressive part of its performance.

Armin Strom Tribute 1 California

Like every Armin Strom watch, the Tribute 1 California’s manually-wound Calibre AMW21 has been assembled twice. After its first assembly, the movement was painstakingly disassembled and each individual part was cleaned, dried, reassembled and lubricated before being meticulously regulated, tested, and returned to the case.

Armin Strom Tribute 1 California

Engraved on each case back, the legend “1 OUT OF 5” confirms the edition size. Every Armin Strom Tribute 1 California watch is presented on a black alligator leather strap with stitching that matches the colour of the dial. The Armin Strom Tribute 1 California will be available in December of 2021 at a price of CHF 17,900.

Armin Strom “Tribute 1” in Black and Blue

Swiss luxury watch brand Armin Strom has launched two new models of its cutting edge Tribute 1 wristwatch.

Armin Strom Tribute 1 Black

Armin Strom Tribute 1 represents a modern interpretation of the classic dress watch. It was introduced in June of this year in an edition featuring a grey dial with an 18k white gold barrel bridge. Limited to only 25 pieces, the Tribute 1 First Edition sold out quickly.

Armin Strom Tribute 1 Black

The new two references – one with a black dial and one with a blue dial – are available in limited editions of 100 each.

This classic manually-wound timepiece has an exquisitely proportioned 38 mm stainless steel case with a slender profile. Each Tribute 1 features extensive hand finishing, craftsmanship and decoration. It is presented on an elegant alligator strap.

Armin Strom Tribute 1 Black

Its understated off-centre dial displays hours, minutes and seconds. In attractively stark contrast to the dial is an adjacent plate whose grenage finish subtly transitions the hue of the dial from one shade to another as the light changes.

Armin Strom Tribute 1 Blue

The already distinctive face is rounded out with a barrel bridge, a feature that has become a hallmark in Armin Strom’s exclusive timepieces. The Tribute 1’s crown is located at 2 o’clock, a detail that enhances wearer comfort.

Armin Strom Tribute 1 Black

Equipped with a highly efficient motor barrel, the in-house Calibre AMW21 delivers a 100-hour power reserve. The legend “1 of 100” engraved on the caseback is a confirmation of the edition size.

Armin Strom Tribute 1 Blue

The “Tribute 1” in Black and Blue watches are available at an exciting retail price of CHF 13,900.

Armin Strom Tribute 1 Black

The Armin Strom Tribute 1 watches are part of the “System 78”collection, which offers fine watchmaking, impeccable hand-finishing and a number of innovative horological ‘firsts’ while maintaining an accessible price point.

Armin Strom The “Tribute 1”

Armin Strom presents the Tribute 1, a brand new classic luxury dress watch in a contemporary context. Contemporary, technically-innovative and beautifully finished, the “Tribute 1″ watch has classic dimensions. This stainless steel watch has a diameter of 38mm and a height of just 9mm. The crown is located at 2 o’clock; a nod to modern design that also enhances wearer comfort.

Armin Strom The "Tribute 1”

The “Tribute 1” belongs to Armin Strom’s System 78 Collection. Every detail of this timepiece reflects the high-standards of luxury watchmaking, particularly when it comes to finishing. Hand polishing the dial side of each barrel bridge takes over 12 hours to complete. To make the inaugural iteration even more special, the manufacture produced the barrel bridge in solid white gold.

Armin Strom The "Tribute 1”

The gear train bridge on the backside is beveled and polished in 60°. The polishing of the hands that I designed for this watch was also extremely time-consuming. The barrel is hand polished and provides 100 hours of autonomous operation.

Armin Strom The "Tribute 1”

The Caliber AMW21 is adorned with Côtes de Genève, the jewel sinks are polished to a gleaming conclusion and the mainplate is circular grained. The balance cock and the stepped escape wheel cock deliver a three-dimensional allure, while their edges are hand beveled to convey an overall sense of luxury.

Armin Strom The "Tribute 1”

The highly efficient motor barrel in the ‘Tribute 1’ is unusual in that the arbor turns around the mainspring within the barrel itself, which makes it more efficient while conserving space.

Armin Strom The "Tribute 1”

The first edition of the “Tribute 1” is available now and is limited to just 25 pieces. It is priced at an intentionally-accessible price point of CHF 13,900. This first iteration is further distinguished by its white gold barrel bridge and a 10-year warranty, exactly double the standard warranty typically offered by Armin Strom.

About The System 78 Collection

The “System 78”collection offers fine watchmaking, impeccable hand-finishing and a number of innovative horological ‘firsts’ while maintaining an accessible price point. Recognizing the passion for haute-horology among many that have historically been excluded from access to fine watchmaking, Armin Strom has committed itself to the consistently dedicating of a portion of its limited production capacity to democratizing access to haute horology timepieces. The collection embodies the watchmaking sensibilities of Claude Greisler and Serge Michel, co-founders of the revitalized Manufacture Armin Strom, who were both born in 1978.

Armin Strom Pure Resonance Sky Blue

The Armin Strom Pure Resonance Sky Blue watch was unveiled during the Watches and Wonders event in Shanghai in April 2021. This limited edition white gold watch features an off-centered blue guilloché dial made by Kari Voutilainen.

In general, Armin Strom carefully maintains a pared-down approach that keeps the brand’s style of watchmaking focused on its essence. How concentrated that style may be, this special-edition head further in that direction, squarely placing emphasis on the watch’s most remarkable feature: the visible dual balances oscillating in resonance. The special blue dial and the matt hand decorated finish are highlighting the Swiss German style of this timepiece.

Armin Strom Pure Resonance Sky Blue

The dial offers a “Kari Voutilainen hand Guilloché” subdial for time displays: Roman numerals dominate the off-center subdial displaying hours and minutes in white with steel hands, while a classic railroad track marks the exact minutes. The smaller subdial at 7 o’clock displays seconds using only a baton-shaped hand and a simple track.

The Sky blue colored hand made Guilloché dial from Kari Voutilainen has a special lack finishing (Email à froid) in order to reinforce the unique look of the dial. The Bridges are decorated with succinct, eye-catching côtes de Genève, applied for the first time in straight lines.

Armin Strom Pure Resonance Sky Blue

It’s absolutely spectacular movement finishing is often overlooked as the hypnotic pulsation of its clutch spring and the synchronized motion of its two balance wheels provide a mesmerizing distraction that invariably captures most of the attention.

The reason for this watch’s improved chronometry can be found in the straightforward approach to the movement: the fewer functions a timepiece must perform, the better it can concentrate on accuracy. In other words, with no superfluous functions this watch can focus fully on providing the time in marine chronometer precision. The time displays receive their portioned energy from the lower regulator, while the upper regulator remains in place to create resonance.

Armin Strom Pure Resonance Sky Blue

The outward design of the Pure Resonance perfectly reflects the purity of Caliber ARF16. It is housed in a slim 42 mm white gold case with reduced lugs and crown and practically no bezel, though the characteristic lip at 6 o’clock remains – an homage to the ability of Armin Strom to customize any of its watches as well as to founder Armin Strom, who offered this space to clients for personal engraving (and it can still be used for that).

Armin Strom Pure Resonance Sky Blue

This special edition of the Pure Resonance remains in line with the philosophy of Armin Strom as a brand: just good, proprietary mechanics presented in an impeccably finished and interesting way. The Pure Resonance Sky Blue is limited to 3 pieces.

Armin Strom Lady Beat

Armin Strom presents Lady Beat, the very first model created specifically for women by the Biel-based luxury manufacture. This new watch belongs to Armin Strom’s recently released System 78 Collection, which highlights innovative watch making at a competitive price.

The Lady Beat is a decidedly feminine one, but one exuding the technical looks and feel of the genuine manufacture movement powering every Armin Strom timepiece. Instead of using the brand’s testosterone-influenced in-house design, Armin Strom has consulted two lady freelance designers to ensure authenticity and a decidedly feminine feel.

Armin Strom Lady Beat

Lady Beat features an off-center dial and slimmer new case with a much smaller diameter. The 38 mm case diameter of Lady Beat is a first at Armin Strom. The highlight of the front of this watch is the visible triplet of bridges echoing the pocket watch inspiration behind Caliber ALA20, just one of many mechanical elements visible on the dial.

Armin Strom Lady Beat watch movement

The contemporary dimensions maintain the essence of Armin Strom DNA while shaping a new aesthetic that showcases the brand’s love for reduction to the essential, enhancing legibility, and maximizing the user experience for discerning female collectors, enthusiasts, and casual wearers.

While the inspiration for this watch originated with Greisler and Michel, they wisely collaborated with two women very well acquainted with designing watches for other women.

Armin Strom Lady Beat movement rotor side

The watch’s winding is automatic for maximum comfort. The visible micro rotor from Gravity Equal Force was redeveloped into a full-sized central rotor on the back to ensure more winding power and a long power reserve.

Armin Strom Lady Beat

Working with the female design consultants, the Armin Strom team decided to orient Lady Beat’s look on Gravity Equal Force to both build on and highlight the freshly launched System 78 collection. While the base idea is rooted in Gravity Equal Force, and the movement remains the centrepiece of any Armin Strom watch, the mechanics have been reordered to ensure both the svelte, wearable character of the watch and to put the spotlight on mechanical dial animation.

The previous case design has been trimmed down even further from the already relatively lithe proportions of Gravity Equal Force (as compared to the rest of Armin Strom’s line) to create the first 38-millimeter case at Armin Strom.

Armin Strom Lady Beat automatic watch

Greisler and the two female designers very quickly settled on a watch filled with soft shapes: the normally very classic lugs of an Armin Strom watch were cast aside in favor of an integrated strap, and the overall look is filled with circles and semi-circles rather than the angular shapes generally associated with this classically male brand.

Another example is that the dial no longer has numerals, but rather more softness thanks to a reduced logo that simultaneously functions as the 12 o’clock marker. Visible screws holding the undulating, patterned dial to the plate below remain visible, though, reminding us unmistakably that this is a technical oeuvre by Armin Strom.

Armin Strom Lady Beat automatic watch black dial

The second hand, which can quickly turn a watch into more of an instrument, has also been foregone here in favor of a clean look. There is no shortage of technical elements on the dial: first and foremost, the visible balance with its mesmerizing rotations practically occupy the position of honor on the dial. The indications, on the other hand, are off-center, as is often the case at Armin Strom, and given less focus than the watch’s beating heart.

Conceived from the get-go to be a technical ladies’ watch, the movement was redeveloped to bring the balance, the beating heart of any watch, to the front of the watch where it is visible at any time. Its hypnotizing movement also allows the wearer to see at a glance whether the watch is running.

Additionally, the team removed the ingenious stop-works declutch system and motor barrel design crafted to transmit equal force to the balance from Gravity Equal Force’s movement to minimize Lady Beat’s movement height and keep its dimensions svelte. And, finally, the team decided to remove the running seconds, deciding that they distracted from the beauty of and focus on the balance in motion, the watch’s pulse.

The Armin Strom Lady Beat features a stainless-steel case and is priced at CHF 16,900.

Armin Strom Gravity Equal Force 18ct Rose Gold Version

After the great success of the Gravity Equal Force model in stainless steel, Swiss luxury watch manufacture Armin Strom has created a new edition in an 18ct rose gold case with black alligator leather strap. The black dial gives the remarkable timepiece an elegant retro character and highlights the new design of the watch with striking contrast.

Armin Strom Gravity Equal Force 18ct Rose Gold Version

Introduced in 2019, the Gravity Equal Force (in stainless steel) is the first model of the new System 78 Collection by Armin Strom. This innovative watch takes the traditional mainspring barrel and turns it on its head by adding a stop-work declutch mechanism combined with automatic winding to create consistent power delivery to the balance.

Armin Strom Gravity Equal Force

A perfect example of Armin Strom’s innovation and expertise in fine mechanical watchmaking, the new Gravity Equal Force watch takes the traditional mainspring barrel and turns it on its head by adding a stop-work declutch mechanism combined with automatic winding to create consistent power delivery to the balance. With a bold redesign of the movement, dial and case, Gravity Equal Force marks the launch of the new System 78 Collection, highlighting innovative watchmaking at a competitive price.

The inspiration behind Gravity Equal Force was a desire to transmit equal force to the balance, thereby increasing the consistency of rate. Building upon the classic stop-works mechanism, Armin Strom developed an ingenious stop-works declutch system that operates inside the mainspring barrel to limit the torque delivered to the balance, providing smooth power delivery. This represents the first time a stop-works declutch mechanism has been added to an automatic winding movement.

Not content with one innovation, Armin Strom found insight in a pocket watch in need of repair from a U.S. collector, which contained a motor barrel design showing clear advantages over the standard going barrel. Inspired, the watchmakers designed a barrel operating in the reverse of a traditional mainspring barrel by driving the going train via the barrel arbor and winding the barrel housing, which both improves functionality and reduces wear.

This state-of-the-art design creates a stable, low-friction axis of rotation for the mainspring to deliver power from the barrel arbor, supported by precision jewel bearings. Though using only a portion of the mainspring by preventing it from completely unwinding, Armin Strom still achieved a power reserve of 72 hours. Wound by a unidirectionally winding microrotor visible from the dial, the mainspring bears a power reserve indicator on the barrel cover for reference.

With numerous small improvements to the going train and winding mechanism, the new Caliber ASB19 demonstrates Armin Strom’s commitment to continually questioning established theory and using in-house R&D to advance horological technology.

The new Gravity Equal Force also differs from previous models with a new off-center dial and slimmer case with a smaller diameter. The highlight of the watch is now the triplet of bridges echoing the pocket watch inspiration behind the ASB19.

The 41-millimeter case, a first for Armin Strom, should appeal to the more classically-inclined collector. The contemporary dimensions maintain the essence of Armin Strom DNA while shaping a new aesthetic that showcases a reduction to the essential. Moving to an off-center dial, the Gravity Equal Force is more legible to maximize the user experience for discerning collectors.

The Armin Strom Gravity Equal Force is the first model of the new System 78 Collection. It features a stainless steel case and is priced at CHF 16,900.

Gravity Equal Force inspiration and development

Gravity Equal Force represents a drive to constantly improve Armin Strom watches with every model. As a creative watch brand focused on innovation, Armin Strom’s watchmakers and movement engineers routinely research and explore concepts across the horological landscape in search of ways to rethink theory and practice.

The Gravity Equal Force development began with a desire to deliver equal force to the regulating system. The result was a stop-works declutch mechanism incorporated into the barrel housing ensuring consistent power delivery to the balance and escapement.

Utilizing a Geneva wheel mounted to the barrel housing cover, the rotation of the mainspring barrel is limited to just 9 full turns out of a possible 12.5. This represents the central 72% of the mainspring’s potential torque curve, the flattest and most consistent portion. As the barrel housing unwinds around the arbor, a pin counts off the rotations on the Geneva wheel until it reaches the locked position and prevents further unwinding.

This limit keeps the power delivery to the balance as consistent as possible and the amplitude in optimal range. Once it reaches the upper limit, the declutch mechanism guarantees the slip of the mainspring and allows the microrotor to turn evenly when fully wound.

A small declutch lever is attached to the Geneva wheel that marks its rotation and power reserve from full to empty. Sitting atop the barrel cover, the power reserve location will change as the watch is wound, providing some playful variation in the dial display.

The new stop-works declutch mechanism coincides with a complete reassessment of the mainspring barrel construction. When a U.S. client brought a vintage pocket watch to Armin Strom for repair, it created an opportunity to explore techniques that were common in earlier watches and update them for use in a modern movement.

Upon inspection it was discovered that it bore a motor barrel whose barrel and winding mechanism are constructed opposite that of the standard going barrel. The standard design sees a central arbor often supported by jewel bearings rotating inside the barrel to wind the mainspring. Once fully wound, the arbor remains fixed while the mainspring pushes the barrel housing and so driving the going train.

A typical mainspring barrel doesn’t rotate in a precision jewel bearing but around the arbor, which means higher friction and less precise rotation. The Armin Strom motor barrel design reversed this so that the barrel housing stays locked after winding, allowing the well supported and more precise arbor to rotate and drive the going train.

This simple change goes against at least a century of tradition, yet, when assessed objectively, it is clear that it is a demonstrably better system as it is more precise and stable during operation of the movement. Armin Strom’s watchmakers built on this idea to create an entirely new watch that launches a brand-new collection.

The development of Caliber ASB19 sees continued improvement throughout all the components thanks to the technological advancement of the previous centuries. A new layout combined with improved geometry for the gear teeth and adjustments provides smoother operation and more robust functionality.

Armin Strom’s focus on innovation and development was kickstarted during the development of its ground breaking Resonance Clutch Spring and has led to the watchmakers rethinking everything in an attempt to innovate where others stagnate. This isn’t limited to mechanics alone; the entirety of Armin Strom’s design aesthetic is evolving to build a new core moving forward.

The previous open-worked display has been replaced by a dial offset from the center, providing a clear indication for the time to avoid any confusion. Retained are the visible barrel and microrotor, though now supported by clean geometric bridges harkening to pocket watches of the past. The entire presentation has the goal of reducing details to the essential for a cohesive package.

The previous case design has been trimmed down to create the first 41-millimeter case for Armin Strom. The iconic lip at 6o’clock, which can be traced back to Mr. Armin Strom himself, is still present, though in a much more streamlined form. Armin Strom has taken the opportunity to improve finishing on every component throughout the movement, creating a new standard for Armin Strom calibers.

The entire philosophy of development at Armin Strom is reorganizing to focus on updating the aesthetic design to signify a new chapter for the brand. The intention is to take every opportunity to rethink watchmaking theory, improve each new watch, and take Armin Strom’s level of finishing ever higher.

The System 78 Collection

The Gravity Equal Force signals a new direction for the brand, launching the System 78 collection to replace the Single Barrel Collection. The collection is intended to be the entry point for Armin Strom, an haute horlogerie collection at a reasonable price point with impeccable finishing and constant invention. The name displays what the brand hopes to create, a System of fine watchmaking available to all who desire it. Every piece will feature an innovation as well as showcasing the watchmaking philosophy of Serge Michel and Claude Greisler, co-founders of the modern Armin Strom, both born in the same year, 1978. Thus the System 78 collection is born.

Armin Strom Minute Repeater Resonance

Swiss luxury watch manufacture Armin Strom presents Minute Repeater Resonance, the world’s first and only resonance chiming wristwatch. This masterpiece combines two complications, resonance and minute repeater. It incorporates two vertically-stacked independent movements; two forms of resonance (oscillators and sound propagation) and two independent mainsprings in one barrel.

The Minute Repeater Resonance was jointly developed by two top development teams in Armin Strom (resonance) and Le Cercle des Horlogers (repeaters).

Inspired by the Bern’s centuries old chiming tower clock, the Minute Repeater Resonance is limited to just 10 pieces in celebration of the 10th anniversary of the Armin Strom manufacture. Masterpiece 2 highlights both the phenomenon of resonance and the sonorous chiming of the time by placing all of the action up front and center dial side.

Activated by a slider on the left side of the case band, two hand-polished hammers at 11 o’clock and 1 o’clock respectively chime the hours and minutes on two three-dimensionally curved gongs encircling the hour/minute subdial. The hammers are visually and technically balanced by the two independent regulators – one for each of the two movements– at 5 o’clock and 7 o’clock.

The case is in Grade 5 titanium for optimal sound transmission (and comfort), and its 47.7 mm diameter allows for a generous volume for the sound to propagate from. The sonorous chimes are also enhanced by attaching the gongs directly to the case.

A specially developed security system maximizes ease-of-use by protecting the minute repeater from accidental damage by blocking operation during time-setting and winding.


Fully visible between the two oscillating balances is Armin Strom’s patented Resonance Clutch Spring – the key to Armin Strom’s mastery of resonance – and the result of three years of intensive research and development.

While it has been long known that resonating coupled oscillators in watch and clock movements improves accuracy, less known is that resonance also conserves energy. Armin Strom’s laboratory testing has revealed gains in precision of 15-20%.

Under a virtually invisible sapphire crystal dial, the dual balances oscillating in synchronization and the two hammers striking the time, the Minute Repeater Resonance stages an unparalleled horological spectacle for both the eyes and the ears.

The Armin Strom Minute Repeater Resonance is a limited edition of 10 pieces in Grade 5 titanium in honor of the 10th anniversary of the manufacture. There will be no more editions.

Inspiration

For the 10th anniversary of its fully integrated manufacture, Armin Strom decided to develop a world-first masterpiece fully highlighting the brand’s savoir-faire. As the industry leaders in resonance, including the brand’s laboratory-certified resonance technology was an easy choice. But Armin Strom’s chief watchmaker Claude Greisler wanted something more: a grand complication.

Inspiration for a minute repeater came from an unusual source: a sixteenth-century tower clock. Armin Strom is based in Bienne in Switzerland’s canton of Bern, and Greisler wanted to pay homage to the region. While the French-speaking region of Switzerland is known for a multitude of famous historical timepieces, Bern has far fewer. But it does have one landmark clock that everyone in the region knows: the thirteenth-century Zytglogge. The clock in this tower has not only served as the city’s main clock for more than 500 years, the tower also served as the reference point for travel times indicated on stone markers along the main cantonal roads.

This clock tower supposedly helped Albert Einstein hone his special theory of relativity while working as a patent clerk in Bern.

The impressive tower clock is animated with automatons: four minutes before the change of the hour, a cock crows, a bear (the symbol of Bern) makes his rounds, and a jester takes the liberty of announcing the hour in advance. And at the top of the hour (and on the quarters), the clock chimes the time for all to hear.

Development

Armin Strom as masters of resonance movements wanted to work in partnership with masters of chiming watches, and Greisler knew the perfect person and team: his old friend Alain Schiesser, founder of Cercle des Horlogers, with whom he had worked with in the past at Christophe Claret. Working behind the scenes, Le Cercle des Horlogers has developed around half of the minute repeaters launched by prestigious Swiss brands over the last few years.

Originally the minute repeater mechanism had been envisaged to be in the traditional position at the back of watch, but the team decided that it deserved equal billing with the resonant regulators dial side where it could be appreciated by all. This brought many technical challenges of its own. Armin Strom not only wanted the resonant regulators and minute repeater hammers and gongs to be fully visible on top of the movement dial side; Greisler and his team did not want appreciation of the animated mechanisms to be potentially diluted by the associated gearing necessary to drive the repeater and going train for the time display. So the movements are inverted with the pinions driving the repeater hammers and hour and minutes transversing the two vertically stacked calibers.

They say necessity is the mother of invention and that’s certainly the case here. Space constraints meant that there was insufficient room for separate large mainspring barrels for each of the two movements, so Armin Strom developed an innovative single barrel with two independent mainsprings inside, each driving its own movement.

The high visibility of the complications dial side also dictates that the watchmakers have to pay very special attention when assembling and regulating the watch as the slightest scratch or mark on the beautifully hand-finished surfaces would be visible to all. Skeletonized bridges and plates (an Armin Strom specialty) allow visual access through the sapphire crystal dial deep into the movement.

While the vast majority of the components were produced in-house at the Armin Strom manufacture, the gongs were made by Le Cercle des Horlogers in a process involving more than 30 different stages including multiple thermic treatments. While the exact process is a closely guarded secret, it is said to be very similar to Patek Philippe’s process for making gongs.

All components are finished to the very highest level, but of special note is the tremblage hand-engraving on the large golden balance cocks supporting the two oscillating balances. While titanium is the perfect metal for both transmitting the resonating sound from the gongs to the ear and ensuring that the watch is relatively light and comfortable to wear, it is a ‘cold’ metal; this coolness is balanced by the warm gold.

Resonance

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, the Armin Strom Resonance Clutch Spring eliminates the necessity for fine tuning the distance, ensuring a much more reliable and efficient resonant system only taking up to 10 minutes to synchronize. 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.

Armin Strom Pure Resonance Edition for Only Watch

Armin Strom is presenting a unique piece of the Pure Resonance especially created for the Only Watch Auction.

Armin Strom carefully upholds the craftsmanship and tradition of Swiss watchmaking while pursuing technical innovation. A pared-down approach that keeps the brand’s style of watchmaking focused on its essence. How concentrated that style may be shows the unique piece created for Only Watch by squarely placing emphasis on the watch’s most remarkable feature: the visible dual balances oscillating in resonance. The groundbreaking movement is housed in a 42 mm stainless steel case with reduced lugs and crown and practically no bezel, though the characteristic lip at 6o’clock remains.

Roman numerals dominate the off-centered blue sunray subdial of the timepiece, displaying hours and minutes with the in-house manufactured steel hands, while a classic railroad track marks the exact minutes. The smaller seconds dial at 7 o’clock has the same coloring as the famous charity auction corporate colors from this year’s edition and uses a baton-shaped hand in steel.

This unique piece can focus fully on precisely providing the time. The time displays receive their portioned energy from the lower regulator, while the upper regulator remains in place to create resonance for improved chronometric precision.

The two beating hearts are synchronized and stands as a symbol and expression of support for the research on Duchenne muscular dystrophy. The Caliber ARF16 showcases the resonant regulators and playful patented resonance clutch spring. The bridges are hand decorated with succinct, eye-catching côtes de Genève which appears in straight lines.

Armin Strom Dual Time Resonance Sapphire Limited Edition

Independent Swiss watch manufacture Armin Strom presents a sapphire case version of its Dual Time Resonance mechanical watch.

The Dual Time Resonance is a horological masterpiece that combines the practicality of two completely independent time indications with the increased precision of two independent movements in resonance. While Armin Strom is known for not covering their movements with a dial to highlight the horology within, the new Dual Time Resonance edition with sapphire crystal case takes transparency to a whole new dimension.

Armin Strom began research and development into using the phenomenon of resonance in a wristwatch with two main goals: the first that any resonant complication should demonstrably improve timekeeping precision, and the second that people should be able to visually appreciate the phenomenon of resonance as it happens.

The Dual Time Resonance features two independent movements side by side, which even further emphasizes the fact that there are two completely separate movements synchronizing oscillations due to the phenomena of resonance.

The Dual Time Resonance Sapphire demystifies and highlights resonance to the extreme, the crystal-clear sapphire crystal case offering views of the movement from all angles.

The patented Resonance Clutch Spring – the result of three years of intensive research and development – connects two individual movements arranged side by side, each independently displaying two time zones and each synchronized with the other through resonance for improved chronometric precision.

Independent movements enable the Dual Time Resonance Sapphire to indicate GMT, a second time zone, or function as a timer or countdown. Completing the indications are independent power reserve indicators and a 24-hour indication serving both displays.

The CSEM (Centre Suisse d’Electronique et de Microtechnique) has officially certified Armin Strom’s Resonance Clutch Spring system as being a true system in resonance. Armin Strom’s laboratory testing has revealed gains in precision of 15-20% for two COSC-certified chronometer-level regulated movements placed in resonance.

The Armin Strom Masterpiece 1 Dual Time Resonance Sapphire launches in a scratch-resistant limited edition of 8 pieces.

With the introduction of the Mirrored Force Resonance, Armin Strom revolutionized both the practical and aesthetical benefits of using the physical properties of resonance in wristwatches. The Mirrored Force Resonance demystified resonance by placing two oscillators resonating through the patented Resonant Clutch Spring front and center. Here, the dials and dual regulators sit on top of two vertically-stacked, independent movements.

To highlight the highest level of horology and micro-engineering, Dual Time Resonance highlights the duality of the two independent resonating movements by replacing the vertical ‘stacked’ movement architecture with horizontal side-by-side movements. This has the added attraction of enabling appreciation of even more of the impeccably finished movement.

Dual Time Resonance Sapphire now removes any and all barriers to appreciation: the case ‘disappears’ in an unabashed celebration of the reliably resonating calibre ARF17 movement seemingly floating between strap ends. The transparent case of Dual Time Resonance largely disappears from view, which amplifies the form-follows-function horizontal movement architecture of the caliber ARF17.

The attraction of sapphire crystal watch cases is (transparently) obvious; the difficulty, though, in cutting, milling, polishing, and assembling sapphire crystal case components is extreme, especially in relatively large — in this case 59 mm long — case components.

Sapphire crystal rates 9.0 on the Mohs scale, as opposed to 9.5 for moissanite and 10 for diamond. Diamond-coated tools spend days cutting, then milling the case components from massive sapphire crystal blocks. These are then left for a few days to allow any tension generated by the heat of machining to be evenly distributed throughout the crystal.

The case is then polished for days, transforming the opaque milled crystal into one that is crystal clear. Sapphire crystal’s main challenge is its extreme hardness. Like the less glamorous but equally contemporary ceramic cases, hardness is the cause of susceptibility to chipping, cracking, or shattering: sapphire crystal is fragile, and this creates a manufacturing process that is very long, and very complicated with a lot of breakage.

Masterpiece 1 Dual Time Resonance was developed as a showcase for Armin Strom’s technical and artistic excellence, bringing the phenomenon 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.

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 – it is less known that resonance also conserves vibrational energy normally lost through supporting the regulator.

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

But the manufacture 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 movements mean 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 connected independent movements 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, the Armin Strom Resonance Clutch Spring eliminates the necessity for fine tuning the distance, ensuring a much more reliable and efficient resonant system only needing up to 10 minutes to synchronise. 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.

The CSEM (Centre Suisse d’Electronique et de Microtechnique) has officially certified Armin Strom’s resonance system based on the Resonance Clutch Spring as being a true system in resonance.

Armin Strom GMT Resonance in Gold

Launched with the first Dual Time Resonance model in titanium, the Masterpiece collection from Armin Strom has now been extended to include versions in white gold and 18 carat rose gold, each in a limited edition of just 8 pieces.

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.

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 minimizes 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.

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 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.

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.

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.

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.

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.

Armin Strom Announces New Authorized Distribution Partner Swiss Prestige in Hong Kong and Macau

The Swiss independent watch manufacture ARMIN STROM has announced a new distributor partnership with Swiss Prestige. Swiss Prestige will bring attentive, personalized services and shopping experiences to Asian luxury consumers with a strong human touch.

“Our focus is on exceptional, luxurious products. With its distinctive designs featuring their in-house movements, all made in small quantities, ARMIN STROM is a terrific addition to our curated selection of watch brands,” said Jacqueline Ng CEO of Swiss Prestige.

This new partnership, an extension of the ARMIN STROM’s existing business network, is undoubtedly a tremendous achievement for the brand and recognition of the company’s creativity, brand value and unstinting effort. “We are talking about developing unique and ground-breaking services and products, all of which will make an incredible user experience” explained Serge Michel, owner of the brand.

ARMIN STROM watches are designed to reveal the inner mechanics of the movement on the front of the dial. “The magnificence of a timepiece is that it’s a tiny, perfectly built mechanical engine that keeps precise time,” explained Claude Greisler CEO of the brand. “The movement is the heart of the watch and being able to see it operate creates a dynamic piece of art. It reflects a centuries-old craft and is a true investment.”

With 20 employees in its Bienne headquarters, ARMIN STROM designs and creates all its own movements and cases. Every watch is hand finished by the company’s highly skilled watchmakers and with the innovative watch configurator the timepiece can be easily configured and personalized.

In watchmaking, skeletonizing is a term used to describe the removal of any extraneous metal from the workings of a timepiece. Founded by master skeletonizer Armin Strom in 1967, the Michel family purchased the company in 2006 and invested in facilities and equipment so the company could begin producing all its own movements for its timepieces.

Swiss prestige is firmly established as a leading distributor of fine Swiss watches throughout Asia. Through its head office and subsidiaries, Swiss Prestige represents well-known Swiss watch brands in Hong Kong, China, Taiwan and Australia. Jacqueline Ng for Swiss Prestige and Serge Michel from ARMIN STROM are extremely satisfied and are looking forward to a successful and cooperative partnership.

ARMIN STROM Mirrored Force Resonance with Handmade Guilloché Dials

After the success of limited edition rose gold and stainless steel models, ARMIN STROM’s Mirrored Force Resonance is now available in a new version with superb, hand-executed 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. Considering the complex production process of these guilloché dials, an extra cost of CHF 5,000 will be applied to the standard retail price of the ARMIN STROM Mirrored Force Resonance.

ARMIN STROM Pure Resonance

ARMIN STROM’s new Pure Resonance offers a more classic stylistic approach and improved accuracy.

The dial now offers just two subdials for time displays: Roman numerals dominate the off-center subdial displaying hours and minutes in black and blue with blued steel hands, while a classic railroad track marks the exact minutes. The smaller subdial at 7 o’clock displays seconds using only a baton-shaped white hand and a simple track.

The goal of the Pure Resonance has not changed: to display the interesting resonant balances while improving overall precision. To this end, brand director Claude Greisler has removed the twin seconds flyback mechanism of Caliber ARF15, replacing them with one clear-cut subsidiary seconds subdial.

The reason for this watch’s improved chronometry can be found in the straightforward approach to the movement: the fewer functions a timepiece must perform, the better it can concentrate on accuracy. The time displays receive their portioned energy from the lower regulator, while the upper regulator remains in place to create resonance.

This conceptual forthrightness is reflected in the design of the movement: state-of-the-art basic Caliber ARF16 showcases the resonant regulators and playful resonance clutch spring. New bridges are decorated with succinct, eye-catching côtes de Genève, applied for the first time at ARMIN STROM in straight lines.

The outward design of this new Pure Resonance perfectly reflects the purity of Caliber ARF16. It is housed in a slimmer 42 mm stainless steel or 18-karat rose gold case (1.4 mm smaller than the original version) with reduced lugs and crown and practically no bezel, though the characteristic lip at 6 o’clock remains – an homage to the ability of ARMIN STROM to customize any of its watches as well as to founder Armin Strom, who offered this space to clients for personal engraving.

ARMIN STROM Manual Hunt Slonem Edition for Only Watch

For the Only Watch Auction 2017, ARMIN STROM is presenting a unique timepiece in association with American artist Hunt Slonem.

The ARMIN STROM Manual Hunt Slonem Edition for Only Watch comes in a titanium case with a diameter of 43.4 mm featuring the manually wound AMW11 calibre manufactured in house with off-centre time display and seconds subdial. Its openwork spring barrel benefits from a remarkable 5 day power-reserve. It goes without saying that the bottom plate and bridges are finely decorated and hand-engraved.

The dial side is a screen onto which Hunt Slonem’s contemporary art has been transferred. A composition of pastel hues and powerful lines continues the artist’s famous “bunny paintings” series. Together with the watch, the successful future bidder will be acquiring a hand-signed original which takes up the colours and motifs of the timepiece in a 46 cm x 31 cm format. For his work entitled “Rex”, the artist has used metal pigments in oil paint as the base for his characteristic linear styling.

Serge Michel, the art lover and proprietor of ARMIN STROM, has long been a fan of Slonem’s work. He was therefore delighted to acquire the world-renowned New York artist for this cooperative venture. The sought-after works which are currently on show in some 250 museums all over the world are created in Slonem’s Brooklyn studio. Apart from his interpretations of tropical fauna and flora, Slonem’s preferred subjects include those “bunny paintings” with which he sets the stage for the Chinese zodiacal sign of his birth year, the hare, and has been doing so since the early 1980s.

ARMIN STROM Mirrored Force Resonance in Stainless Steel

After the great success of the rose gold premier model, the limited edition Mirrored Force Resonance has now been augmented by a stainless steel variant with a dark blue alligator strap dedicated to the element of water. The white dial endows this exceptional timepiece with an elegant retro character and sets the stage for the resonance mechanism with striking contrasts.

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:
1. A stabilizing effect on timekeeping (advantageous to accuracy).
2. A conservation of energy (think of a professional cyclist riding in the shadow of anothercyclist in a racing situation).
3. 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 counter clockwise. 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.

Armin Strom’s Mirrored Force Resonance Wins the Prestigious International Red Dot Design Award

The independent Swiss watch manufacturer ARMIN STROM has won the Red Dot Design Award 2017 for excellence in product design.

ARMIN STROM’s Mirrored Force Resonance contains more than just great mechanical design; this groundbreaking timepiece comprises an innovative, sophisticated mechanism created for the pursuit of precision in a way that has never before been seen in a wristwatch: the eminently visible animated resonance clutch spring that connects two oscillators, the most sensitive part of a watch’s movement.

Thus, the top of the movement becomes a stage for the stars of the timekeeping show underneath a transparent dome of scratch-resistant sapphire crystal, putting the fascinating functionality of the oscillating balances squarely in the spotlight while simultaneously improving the watch’s precision using the phenomenon of resonance.

The international award, which is already celebrating its 60th anniversary, pays tribute to outstanding international product design in 31 different categories. In 2017, the prize winners were selected by a prestigious jury with some 40 members. It is made up of independent designers, professors and professional journalists who assess the products in an evaluation process lasting for several days.  More than 5,500 products from 54 different countries were entered this year. The winners were officially announced at a prize ceremony and gala on 3 July in Essen Opera House.

Armin Strom Mirrored Force Resonance Fire Limited Edition

ARMIN STROM presents Mirrored Force Resonance Fire, a resonating dual regulator complication based on a phenomenon of physics known as resonance.

Two oscillating bodies in close proximity influence each other and eventually synchronize; this phenomenon is known as resonance. In traditional watchmaking, with resonance techniques the accuracy and precision of mechanical timepieces can be improved.

However, this sophisticated and demanding horological technique has rarely been attempted, let alone mastered. 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.”

Christiaan Huygens (1629-1695), 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:-

  1. A stabilizing effect on timekeeping (advantageous to accuracy).
  2. A conservation of energy (think of a professional cyclist riding in the shadow of another cyclist in a racing situation).
  3. 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.

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.

ARMIN STROM, a full-fledged manufacture with in-house manufacturing capability, has developed a special mechanical movement incorporating resonance techniques. The resonant Caliber ARF15 is a classically constructed manually wound movement that was conceived, manufactured, assembled, and regulated in-house. It 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, with a novel, yet impeccably executed finish providing a roomy and stable stage for the real show: the symmetrical twin display of seconds, which are bound by a single spring.

The resonance clutch spring needed to realize the 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. 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 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 watch, one rotating clockwise and the other counter-clockwise, 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 Mirrored Force Resonance is the most complicated timepiece that Armin Strom manufactures and a patent has been registered on it.

Claude Greisler’s idea behind the 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. ARMIN STROM’s Mirrored Force Resonance is a new, better, and more interesting way of executing and displaying an old idea. 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.

The Mirrored Force Resonance is set to premier at London’s SalonQP, which takes place November 3-5, 2016. After that it will embark upon a world tour, starting with the Salon des Grandes Complications in Dubai with subsequent stops spanning the globe from west to east before returning to Switzerland.

Armin Strom Edge Double Barrel Rose Gold Limited Edition

Armin Strom’s Edge Double Barrel, the first model in the brand’s new Edge collection, is now available in 18k rose gold.

Introduced at BaselWorld 2016, manual-wind Edge Double Barrel is powered by an innovative new Armin Strom movement housed in the 46.80mm case. The ARM16 caliber is composed of unusual polygon and angular-shaped components.

The large case size deepens the sense of dimensionality of the open-worked movement, which is visible from the front and back of the timepiece. The hand-beveled bridges contrast with a cross-grinding surface decoration, adding to the watch’s industrial appearance. Altogether, the mechanical elements and design create a captivating aesthetic.

A close look reveals that Mr. Edge, official ambassador of the collection, is composed of many of the same individual components as the ARM16 movement. He’s the creation of the brand and Biel artist Herbert Krake, aka Tarkin, to serve as a communications tool.

With his Transformer-like, brawny physique, the futuristic Mr. Edge makes an intense impression, matching the bold statement and design language of the Edge collection. The robot’s likeness will appear on advertising and marketing support for the collection, which Armin Strom plans to extend with forthcoming new models.

Armin Strom Gravity Sailing Limited Edition

To celebrate the exciting and successful second season of the Armin Strom Sailing Team, Armin Strom created a limited commemorative edition of its Gravity collection and gave the team’s skipper Flavio Marazzi the first of 32 watches produced for the series. Armin Strom owner Serge Michel presented the special timepiece to Marazzi during a ceremony on July 10at the Lake Garda competition in Malcesine, Italy.

Striking black and orange colorations on Gravity Sailing’s dial and strap match the design of the team’s catamaran and its sail. The micro rotor of the automatic timepiece is visible from the dial side.

Currently the Armin Strom Sailing Team is in fourth place in the 2016 Great Cup 32 Sailing Series, which is held across Europe. The catamaran reaches speeds of up to 40 knots and appears to soar airborne when at top velocity. Skipper and helmsman Marazzi is Switzerland’s most successful sailing competitor, a four-time Olympian, and an Armin Strom ambassador. There are two more races before the series concludes in Marseille, France on October 13-16.

Armin Strom Max Chilton Edition Edge Double Barrel

The independent Swiss watch brand ARMIN STROM has created a custom edition of its Edge Double Barrel  wristwatch together with pro driver Max Chilton, a friend and brand ambassador. The Max Chilton Edition Edge Double Barrel commemorates his competition in the North American Verizon IndyCar Series this year.

Drawing on Chilton’s number and IndyCar, ARMIN STROM’s designers integrated a number of eye-catching details. On the dial side, Chilton’s numeral 8 appears in the small seconds register. Striking blue hour numbers match the blue on his turbocharged Chevrolet race car. A special plate on the back is etched with Chilton’s “Max” logo and notes this special series is limited to just eight timepieces.

Along with the Chilton design additions, ARM16 caliber features the timepiece’s unusual geometric and angular components. Unconventional cross-grinding decoration of the hand beveled bridges intensifies the watch’s industrial feel. The bezel is enhanced with a series of cutouts. The larger 46.80mm diameter provides more depth and dimensionality to the caliber, with the time indications positioned slightly off-center, an ARMIN STROM signature.

ARMIN STROM Cognac Watch

To commemorate its new partnership with Wealth Solutions in Poland, Armin Strom created a highly unusual wristwatch. The movement of the mechanical timepiece features a small capsule containing a 1762 Gautier Cognac, which was owned by Wealth Solutions.

Armin Strom chief horologist Claude Greisler devised a concept that protects the movement while incorporating the rare spirit. A sealed sapphire crystal disc positioned at 5 o’clock captures the rare Cognac. Manual wind with a five-day power reserve, the watch will be produced in stainless steel, 18k rose gold and titanium cases. On the backside, a hand engraved design of a bunch of grapes decorates the base plate.

Founded in 2007, Wealth Solutions curates and sells exceptional products, such as art, fine wine and spirits, and watches, to Polish collectors and other clients. In April 2014 Wealth Solutions purchased the oldest authenticated bottle of Cognac- a 1762 Gaultier Cognac bottled in 1840—ever sold at a public auction.

In a ceremony on November 4, 2015, announcing Wealth Solutions as the new Armin Strom distributor in Poland, the rare bottle was opened, decanted and sealed in flacons. Armin Strom designed a disc capsule of sapphire crystal that is sealed to contain drops of the prized Cognac.

The manual-wind Cognac Watch, with the capsule at 5 o’clock and the hand engraving on the base plate, exemplifies Armin Strom’s philosophy of innovation while maintaining the traditions of Swiss watchmaking.

ARMIN STROM Tourbillon Skeleton Earth

ARMIN STROM’s new Tourbillon Skeleton Earth model is specially designed to highlight its technical prowess. With this new model, the skeletonizing of the tourbillon compounded the technical challenge for Armin Strom.

Ultimately the skeletonizing enhances the movement’s mechanical artistry, with PVD colorization of the main plate emphasizing the caliber’s layered construction. Along with the constant rotation of the tourbillon, owners will observe the animation of the double going barrel while the watch is wound.

The ARMIN STROM Tourbillon Skeleton Collection will be produced in the brand’s signature elements of Fire (18k rose gold), Water (stainless steel), Air (titanium) and Earth (black PVD coated stainless steel). It will feature an alligator horn-back strap as well as an alternate rubber strap.

ARMIN STROM Tourbillon Skeleton

Swiss watch manufacture ARMIN STROM’S new Tourbillon Skeleton celebrates the mechanical artistry of the most complex and prestigious horology complication. With this introduction, the independent Swiss manufacture continues to propel the brand into future while honoring the vision and passion of the brand’s founder, master skeletonizer Armin Strom.

Tourbillon Skeleton is a new timepiece specially designed to highlight its technical prowess. An elite circle of watch Manufactures are capable of producing a tourbillon. With Tourbillon Skeleton, the skeletonizing of the tourbillon compounded the technical challenge for Armin Strom. Ultimately the skeletonizing enhances the movement’s mechanical artistry, with PVD colorization of the main plate emphasizing the caliber’s layered construction. Along with the constant rotation of the tourbillon, owners will observe the animation of the double going barrel while the watch is wound.

Armin Strom founded his eponymous brand in 1967 and retired in 2011, after selling the company to the Michel family. Owner Serge Michel and chief horologist Claude Greisler have enhanced the brand’s capabilities by establishing an independent Manufacture in Biel/Bienne that opened in 2009 to develop and produce movements. The company introduced its first manual-wind tourbillon in 2012 and a micro-rotor tourbillon in 2013.
