Armin Strom Dual Time GMT Resonance First Edition

Armin Strom unveils entirely new DUal Time GMT Resonance timepiece

AUGUST 29 2024 | Geneva Watch Days 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.

Tinkler 1958: Precision at a Quarter Turn

A faithful tribute to the original model, the Tinkler 1958 repeater celebrates Angelus’s rich heritage of striking watches. Driven by a self-winding quarter-repeater movement, this double limited edition, available in gold or steel, continues the tradition of measuring instruments that built the manufacture’s reputation. From its establishment in 1891, the name Angelus has been synonymous with the chiming of a bell, a legacy reinforced by one of the Maison's first patents for a silent strike governor in 1896. Since then, repeater mechanisms have remained at the heart of Angelus collections, even being adapted into Braille-repeating watches for blinded soldiers during the First World War.

Inspired by this glorious history, Angelus is reissuing one of its rarest and most refined models: the Tinkler, based on the original 1958 edition. In 1958, Angelus filed a patent for a striking wristwatch, which was immediately followed by the original Tinkler—a pioneer of water-resistant, self-winding quarter-repeater watches. The new 38-mm case charms with a decidedly 1950s aesthetic that is clean, understated, and elegant. At 9 o’clock, the crown is balanced by a pusher that activates the quarter repeater, serving as a functional and historical hallmark of this legendary model.

The Tinkler 1958 edition is driven by the new Angelus A600 calibre, a mechanical self-winding movement that beats at 4Hz and offers a 70-hour power reserve. On request, the pusher at 9 o’clock triggers a sequence where each hour is marked by a clear strike on the first gong, followed by a double strike on two gongs to signal each quarter hour. The movement's finishing demonstrates the watchmaker's extreme attention to detail, featuring a snail-finished main plate, palladium-plated bridges adorned with Côtes de Genève, and a tungsten sunburst oscillating weight.

This new release is part of the La Fabrique line, where Angelus continues its legacy as a maker of specialty watches designed for specific activities or professional uses. The Tinkler 1958 is limited to 15 pieces in 18-carat yellow gold and 25 pieces in stainless steel, each paired with an alligator flank leather strap—ink blue for the gold version and saddle brown for the steel. Combining a modernist-style numeral 12 with exclamation-shaped hour markers at the quarter positions, the watch serves as a modern embodiment of a daring yet functional tradition.

Angelus Instrument de Vitesse - 60 Seconds Flat

Instrument de Vitesse, a new opus in the La Fabrique collection, revives the golden age of timed races. This single push-piece chronograph seems to have been plucked from the dashboard of a vintage GT car. It is equipped with a single timing hand – the centre seconds hand – and can time a maximum of one minute. With its sleek and refined retro sports look, Instrument de Vitesse is intended for enthusiasts of watchmaking history and culture. Housed in a 39-mm steel case, its 4.20 mm manually wound Manufacture calibre ensures that the finished timepiece is less than 10 mm thick. Instrument de Vitesse is available with an ivory-white or ebony-black dial in two limited series of 25 timepieces each.

Appearances can sometimes be deceptive. At first glance, Instrument de Vitesse does not appear to be a classic chronograph. With its three central hands, it looks like a watch... with three hands, but the tachymeter scale running around the outer edge of the dial reveals its chronometric function. For this is a chronograph presented in its purest expression, dedicated to timing short bursts – a measuring instrument designed to take average speed readings over a maximum of 60 seconds. This, in turn, casts new light on the crown, which also acts as the chronograph’s single push-piece to set the slender centre seconds hand in motion.

Chronoswiss presents the ReSec Snake: A Venomous Twist on Modern Mechanical

Known for bold evolutions of mechanical wristwatches and daring designs, Chronoswiss unveils its latest creature: the ReSec Snake. Slithering between heritage and rebellion, this timepiece is a hypnotic blend of color, contrast, and kinetic energy — proof that modern mechanical watchmaking still has a few fangs to bear.

The Snake’s Bite

The ReSec Snake coils into view within a 42mm titanium case, coated with a mesmerizing color-changing PVD-coating that shifts from emerald green to turquoise, depending on the light. It’s not just a case — it’s iridescent armor, capturing the reptilian allure of a serpent in motion. Paired with a contrasting white rubber strap, the Snake wraps around the wrist with smooth, tactile elegance.

But the true venom lies beneath the sapphire crystal. A green CVD-coated dial, hand-guillochéd in the Lucerne Atelier, pulses with depth and hypnotic texture. It’s a dial that doesn’t just tell time — it seduces it.

Take a closer look, and the architecture reveals itself: the iconic 3D regulator layout of the ReSec series slithers across the dial, framed by green hour and minute rings and a retrograde second display, like the flick of a serpent’s tongue. Underneath, the exposed gear train glimmers in contrasting tones — a mechanical exoskeleton that moves with silent precision.

Fangs Beneath the Surface

Powering this cold-blooded beauty is the Chronoswiss Manufacture Caliber C.6005, featuring a 55-hour power reserve, ruthenium-plated finishing, and a radial Côtes de Genève motif. It’s mechanical watchmaking at its sharpest: sleek, silent, and engineered to strike.

Limited. Lethal.

Only 100 pieces of the ReSec Snake will ever exist — a rare breed for collectors with a taste for the untamed. The ReSec Snake is a statement: of daring, of detail, and of defiance — proving once again that at Chronoswiss, we don’t follow rules. We shed them.
