Back in sleek anthracite: Armin Strom unveils the One Week Manufacture Edition

JUNE 25 2024    |    Novelties

Biel/Bienne, Switzerland, 26 June 2024: Following the inaugural redesigned One Week First Edition that made its debut in 2023, Armin Strom unveils a new version of the successor to its first-ever manufacture movement with the One Week Manufacture Edition. The highly architectural openworked movement, housed in a sleek and sporty steel case with an integrated bracelet, is now presented in a range of grey and anthracite hues. Limited to 100 pieces, the One Week Manufacture Edition foregoes colour to bring out the beauty of its uniquely constructed manual calibre.

15 years ago, independent watchmaking brand Armin Strom took a major leap that would forever change its trajectory. Realising that the path to true independence lies in mastering every step of the process, it established its very own manufacture in Biel. A year later, the first timepiece produced by its vertically integrated manufacture was unveiled: the One Week. Entirely developed and manufactured in-house and designed with symmetrical harmony in mind, it stood out thanks to its unique movement architecture featuring two barrels that together provide a seven-day power reserve. This milestone marked the beginning of many new calibres and innovations by the Armin Strom manufacture, showcasing their dedication to the science of movement and garnering the admiration and respect of even the most discerning and seasoned collectors.

The new One Week Manufacture Edition completely reimagines this milestone calibre in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.

As Armin Strom founder Serge Michel notes: “Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.”

Sporty yet classy, this model exudes calmness and serenity with its anthracite tones and the symmetrical harmony of its in-house movement.

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.

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.

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.

Greubel Forsey Unveils Final Editions of the Balancier Convexe S² in White and Black Ceramic

Greubel Forsey introduces the final and most exclusive editions of the Balancier Convexe S²: one in black ceramic with 5N red gold, and one in white ceramic, each strictly limited to 11 pieces.
These editions conclude a calibre developed through five years of mechanical and architectural exploration, with production set to cease permanently in 2026.

The Convexe case (41.5 mm) and movement were conceived as a single architectural whole, integrating Greubel Forsey’s signature 30° inclined balance wheel system as the visual and chronometric centre. The openworked movement features 301 components, including a 68‑part escapement platform, and is 
powered by two rapid-rotation coaxial barrels delivering a 72‑hour chronometric reserve.

Finishing remains uncompromising: frosted titanium bridges, polished bevels, hand‑finished countersinks, and meticulous transitions — even on invisible components.

Two Final Interpretations
Black Ceramic & 5N Red Gold
A dramatic contrast of dark architecture framed by ceramic, with red gold adding warmth and sculptural depth.The interplay of matte and polished surfaces enhances the piece’s three‑dimensional form

White Ceramic
A purist, graphic expression that highlights the structural geometry of the movement through light and shadow.The monochromatic case offers clarity, openness and a distinctly technical aesthetic.

Both editions preserve the characteristic S² display: suspended hours/minutes bridge, small seconds, and sector power‑reserve indication beneath a curved sapphire crystal.

This launch marks the concluding chapter of the Balancier Convexe S²’s five‑year evolution — not an iteration, but a final statement. As of 2026, Greubel Forsey will begin a gradual shift toward an almost entirely new collection, retiring earlier calibres with intention and ceremony rather than quiet discontinuation.
