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.

Moritz Grossmann Presents the New BENU Power Reserve: Tradition Refined

Moritz Grossmann, the independent Saxon manufacture celebrated for its uncompromising craftsmanship and technical ingenuity, introduces the latest evolution of its iconic BENU Power Reserve. This new interpretation embodies the brand’s guiding principle: progress in harmony with tradition.

A Dial That Captures Light and Time
The dial is the face of a watch — a canvas where heritage meets artistry. For the first time, the BENU Power Reserve combines its signature linear power reserve indicator with Azurage decoration. This intricate guilloché pattern of ultra-fine concentric grooves animates the outer chapter ring, creating a captivating interplay of light. The softly textured matte center in shimmering argenté silver contrasts with applied blue numerals and indices, while the brand logo and minute track appear in understated grey.

Completing this refined composition are newly designed hands, handcrafted from steel in the Glashütte atelier. Each hand is meticulously beveled, polished, and then heat-blued using traditional thermal treatment. Their elegant curvature and needle-fine tips exemplify the precision and artistry that define Moritz Grossmann.

The Poetry of Mechanics: Power Reserve Indicator
Mechanical timepieces invite interaction, and the power reserve display is a charming expression of this dialogue. Positioned beneath 12 o’clock, the linear indicator reveals a two-tone bar driven by a differential gear train. When fully wound, the bar appears white; as energy diminishes, a blue segment gradually advances — a subtle yet constant reminder of the living mechanism on the wrist.

Inside the Case: Calibre 100.2
At the heart of the BENU Power Reserve beats the Calibre 100.2, an evolution of the manufacture’s foundational movement. This hand-wound calibre incorporates a differential mechanism for the power reserve display and features the brand’s signature innovations: manual winding with a pusher, a cantilevered balance cock with micrometer screw adjustment, and a separately removable winding module. Through the sapphire crystal back, the movement reveals its artistry — broad Glashütte ribbing, hand-engraved cocks, and raised gold chatons secured by blued screws.

Classic Elegance in Every Detail
The BENU Power Reserve is offered in rose gold and white gold, each with a 41 mm case that reflects the brand’s commitment to timeless proportions. The case surfaces are finely brushed to a soft matte sheen, complemented by a cross-grooved crown and slender lugs. A grey hand-stitched leather strap with blue stitching echoes the dial’s accents, completing a harmonious design that speaks to connoisseurs of understated luxury.

A Legacy Reimagined
Founded in 1854 by visionary watchmaker Moritz Grossmann, the Glashütte tradition was revived in 2008 by master watchmaker Christine Hutter. Today, the manufactory continues to honor its heritage through innovation, artisanal excellence, and a dedication to the finest German craftsmanship.

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.

Neo Digiteur: Chronoswiss Revives the Mechanical Digital Icon

Chronoswiss proudly unveils the Neo Digiteur, a bold reinvention of an icon that first challenged convention two decades ago. Originally introduced in 2005 by founder Gerd-Rüdiger Lang, the Digiteur was a mechanical digital timepiece—a watch without hands—that defied expectations and celebrated horological artistry. Today, the Neo Digiteur returns sharper, stronger, and more modern than ever, crafted in stainless steel and infused with the pioneering spirit of its predecessor.

The design is architectural and tailored, with a rectangular case measuring 48 by 30 millimeters. Its sculptural lines are accentuated by sandblasted and polished finishes, while a reimagined onion-style crown ensures both elegance and ergonomics. At its heart lies a rare complication: a jumping hour regulator without hands. Time is displayed through three apertures—the jumping hour at twelve o’clock, digital minutes at center, and running seconds at six o’clock—creating a mechanical digital regulator that feels futuristic yet deeply analog.

Powering this display is the hand-wound Chronoswiss Caliber C.85757, beating at 3 Hz and offering a 48-hour power reserve. Developed entirely in-house, the movement features artisanal details such as hand-guilloché bridges and a sapphire crystal caseback that pays tribute to historic Fleurier calibers. Two limited editions express distinct personalities: Neo Digiteur Granit with an anthracite dial and Neo Digiteur Sand with a warm 4N sandblasted finish. Each version is limited to just 99 pieces, making the Neo Digiteur not a reproduction, but a true reinvention—a collector’s piece and a statement of mechanical artistry.
