SEPTEMBER 13 2024 | Novelties

Embark on a journey beyond the stars with Chronoswiss’ latest horological marvels: The Space Timer Deep Space and Space Timer Supernova. At Chronoswiss, the allure of the cosmos has always been more than just a distant fascination - it’s a canvas for innovation and creativity. This year, the journey continues as we push the boundaries of watchmaking with two new models that capture the awe-inspiring vastness of space: the Space Timer Deep Space and the Space Timer Super Nova.

A Journey Through the Cosmos: Space Timer Deep Space
The Space Timer Deep Space is a masterclass in blending artistry with technical prowess. Encased in a 44mm stainless-steel case, bathed in a striking blue CVD coating, this timepiece invites the wearer to venture into the unknown. Its matching blue hornback alligator leather strap is not just an accessory, but a continuation of the deep, serene hues that define this cosmic masterpiece.

The dial of the Space Timer Deep Space is a marvel of contrasts and textures. On one side, a meticulously printed depiction of Jupiter and its fiery moon, IO - the most volcanically active world in our solar system - unfolds across seven layers of vivid detail. The other half of the dial, divided by an elegant guilloche-line, is a symphony of hand-guilloché patterns, also finished in a deep blue CVD coating, representing the boundless mystery of deep space. The 3-dimensional dial, with its hovering bridge beneath the translucent ITR-2 hour, minute and date rings, create a microcosm of the universe right on your wrist.

A Stellar Explosion: Space Timer Supernova
The Space Timer Supernova captures the cataclysmic beauty of a star’s explosive death, transforming it into a wearable work of art. Housed in a matte grey stainless-steel case and complemented by a black calf leather strap, this timepiece evokes the raw power and elegance of a supernova.

Its dial is a study in contrast and motion. The two-toned surface, split between galvanic black and galvanic silver, symbolizing the last evolutionary stage of a planet in the endless darkness of space. The hand-guillochéd textures bring depth and dimension to the dial, while the red ITR-2 hour, minute and date rings, along with the seemingly floating titanium moonphase at 6 o’clock, add a striking vibrancy to the scene. It’s a watch that tells a story of cosmic creation, where every glance at the dial is like peering into the depths of a galaxy.

The Engine Behind the Stars
Both the Space Timer Deep Space and the Space Timer Supernova are powered by the Chronoswiss C.308 caliber, a movement as precise and powerful as the celestial bodies it emulates. With a 42-hour power reserve and a frequency of 4Hz, this caliber ensures that time is not just kept but mastered, like the galaxies themselves.

A Limited Odyssey
In the vast expanse of the universe, uniqueness is rare. The Space Timer Deep Space and Supernova are no exceptions. Both models are limited editions of 50, offering a select few the chance to wear a piece of the cosmos on their wrist. These timepieces are not just watches; they are journeys—expeditions into the unknown, where artistry, innovation, and the infinite wonders of the universe converge.

Chronoswiss invites you to step beyond the boundaries of Earth, to explore the depths of space and the power of a supernova, all within the confines of a watch. These are not just timepieces—they are the embodiment of mankind’s eternal quest to reach for the stars.

Fully-integrated manufacture brand Armin Strom celebrates 15 years and heads into the future

Armin Strom co-founders Serge Michel and Claude Greisler look back on 15 years of achievements including 17 exclusive movements, patents, unique designs and 97% in-house production depth. 15 years ago, Armin Strom transformed from a one-man show to a fully integrated manufacture brand when entrepreneur Serge Michel and master watchmaker Claude Greisler took over the reins.

Since 2009, the two childhood friends have been dedicating their lives to the science of movement, building up an independent manufacture with a team of 38, including 22 skilled watchmakers able to turn raw steel bars into hundreds of complex, interconnected watch components. So far, this has resulted in 17 brand-unique different calibres with a signature open-worked design divided among the brand’s three main pillars: System 78, Resonance and Masterpiece.

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.

Chronoswiss Celebrates 30 Years of Horological Innovation with the Opus Purple Rain Limited Edition

Chronoswiss celebrates three decades of horological mastery with the launch of the Opus Purple Rain, a bold and limited edition chronograph that reimagines the brand’s iconic skeletonized timepiece. Limited to just 30 pieces worldwide, this anniversary edition marks a milestone in modern independent watchmaking, honoring the legacy of the original Opus while pushing the boundaries of design and mechanical transparency.

First introduced in 1995 by Chronoswiss founder Gerd-Rüdiger Lang, the Opus revolutionized the chronograph landscape by exposing its intricate movement architecture on the dial side—a radical departure from the traditionally closed and utilitarian chronographs of the time. The Opus became a symbol of mechanical artistry and a signature of the brand’s avant-garde spirit.

The Opus Purple Rain carries this legacy into the future with unapologetic flair. Encased in Grade 5 titanium and finished with a radiant purple CVD coating, the watch is both lightweight and visually arresting. Its skeletonized dial, also rendered in ultraviolet hues, reveals the ruthenium-coated Chronoswiss C.741S automatic chronograph caliber, offering a 46-hour power reserve and a full suite of chronograph functions including central seconds, 30-minute and 12-hour counters, small seconds, and date.

Adding to its rebellious character is a white UV-reactive leather strap that transforms into glowing purple when exposed to sunlight—an unexpected and surreal tribute to the energy behind this creation. Signature Chronoswiss elements such as the onion crown, coin-edged bezel, and patented Autobloc screw-in lugs remain intact, anchoring the watch in its heritage while embracing a futuristic aesthetic.

“The Opus Purple Rain is not just a commemorative piece—it’s a statement,” said Chronoswiss CEO Oliver Ebstein. “It embodies the spirit of mechanical transparency and innovation that has defined Chronoswiss for 30 years. This is a watch for those who dare to see how far precision and design can be pushed.”

With only 30 pieces produced, the Opus Purple Rain is destined to become a collector’s treasure—a celebration of the past, a vision of the future, and a mechanical theatre on the wrist.

The Armin Strom One Week Titanium Skeleton, an openworked masterpiece now fully skeletonized to reveal the intricate heart of its mechanics, combines striking design with precision engineering. Encased in lightweight titanium grade 5, it balances strength with comfort, providing a feeling of lightness that makes it easy to wear all week long.

The Armin Strom One Week Titanium Skeleton is a showcase of skeletonization, a technique that is rooted in Mr. Armin Strom’s philosophy and heritage. He sought to enhance depth and three-dimensionality while avoiding see-through to maintain elegance.

The 2023 One Week was already openworked by nature, but this version goes even further, removing more material to highlight the movement’s complexity. Few watches combine openworking and skeletonization at this level. The small seconds dial is skeletonized, revealing the power reserve level and the escapement wheel for a 3D mechanical animation. The mainplate and the barrels are also skeletonized enhancing aesthetics. Thanks to this skeletonization, the power reserve indicator is highlighted as well as the cone mechanism, reminiscent of ancient pocket watches. A major highlight is the case back, offering a mesmerizing view of the entire mechanism.

With a 7-day power reserve, this watch keeps time accurate for an entire week without needing winding. The hand-finished details reflect the level of craftsmanship behind its design. Limited to 100 pieces, the One Week Titanium Skeleton offers a refined, functional timepiece that blends robustness and comfort in a minimalist package.

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.
