A Splash of Fresh Green: Moritz Grossmann Debuts the TEFNUT Silver-Plated by Friction Anniversary Watch

The year 2026 marks a historic milestone for the Moritz Grossmann manufactory in Glashütte, as it celebrates the 200th birthday of its visionary founder and namesake, born on March 27, 1826. A genius watchmaker, scientist, author, and initiator of the German Watchmaking School, Grossmann profoundly shaped the craft of horology and the fate of his hometown. Rather than merely imitating historical concepts, the modern manufactory honors his legacy by blending his cutting-edge philosophy with modern engineering. This dedication to technological perfection and exceptional aesthetics cements its place among the world's elite elite watchmakers.

To commemorate this bicentennial occasion, the brand has unveiled its third anniversary special edition: the TEFNUT Silver-Plated by Friction. Debuting on April 29, 2026, this launch presents an exclusive premiere for collectors—the very first time that the sleek TEFNUT model is made available in a stunning 750/000 yellow gold case, alongside a 750/000 white gold version. Both variations pay homage to their heritage by incorporating an "1826" engraving on the balance cock and showcasing a vintage 1875 "M. GROSSMANN" logo on the dial.

At the heart of the timepiece lies the ultra-flat manufactory calibre 102.1, a hand-wound movement measuring just 4 mm in height and 26 mm in diameter. This compact footprint enables the watch to retain its remarkably elegant, low-profile silhouette. The calibre embodies classic Grossmann pillar movement architecture with a 3/5 plate, incorporating his signature raised gold chatons, an optimized mainspring barrel with bilateral jewel bearings, and a stepped balance cock with a micrometer screw. Each component is meticulously hand-finished to ensure absolute technical and visual distinctiveness.

The defining aesthetic feature of this model is its striking dial, which boasts a rare "silver-plated by friction" finish. Executed entirely by hand in the brand's ateliers, a master artisan brushes a specialized paste of silver powder, salt, cream of tartar, and water onto the brass surface to create a velvety, fine-grained texture that beautifully diffuses light. To provide a contemporary contrast, the numerals, minute scale, and historic logo are rendered in a vibrant green hue. Hovering above are extraordinarily fine, hand-crafted lance-shaped hands, polished in gold for the yellow gold model and annealed to a brown-violet tone for the white gold edition. Each variation is strictly limited to just 12 pieces worldwide.

Opus Dakar Sundown: A Two-Tone Symphony of Desert Sunset and Fine Skeletonized Horology

Chronoswiss has officially introduced the Opus Dakar Sundown, a striking new interpretation of the celebrated Opus Dakar that captures the fleeting magic of sunset over the desert. Housed in a distinctive 41mm two-tone case crafted from stainless steel and 18ct red gold, the timepiece masterfully blends the rugged spirit of adventure with refined luxury. The warm glow of precious metal flows seamlessly into the robust steel construction, mirroring the final golden rays dancing across endless dunes. This ultimate celebration of contrasts is beautifully completed by a sand-colored nubuck leather strap that evokes the warm tones of sunlit, weathered terrain.

At the heart of the watch beats the Chronoswiss Manufacture Caliber C.741S, a fully skeletonized automatic chronograph movement that transforms every measurement of time into a visual spectacle.

A running small seconds display at 9 o'clock provides a constant indication of the movement's heartbeat, while a highly unique, analogue pointer date display at 3 o'clock enhances its everyday practicality.

The skeletonized, CVD-coated brown dial draws inspiration from the rich palette of the desert, where warm tones create a composition that is both timeless and adventurous. By exposing the intricate mechanics beneath the surface, every skeletonized bridge, wheel, and component directly contributes to a captivating, mechanical canvas. The hands are crafted in the elegant Breguet Losange shape and rhodium-plated to ensure striking contrast against the dark, galvanic black perlage of the base plate.

Crafted in solid 23 pieces, the 41mm case features an 18ct red gold bezel with partial knurling, a screw-down case back with a red gold coin-edge ring, and Chronoswiss’s iconic onion crown. The total weight of gold used in this exceptional construction is 21.4 grams. Offering a water resistance of 3 bar (30 meters), the watch is equipped with screw-in lugs utilizing the patented Autobloc system. For over three decades, the Opus collection has embodied the bold spirit of Chronoswiss; the Opus Dakar Sundown brilliantly reimagines this legacy, shaped by craftsmanship and illuminated by one of nature's most spectacular moments.

Armin Strom Unveils the Dual Time GMT Resonance Rose Gold

Armin Strom presents a refined and visually striking evolution of its celebrated Dual Time GMT Resonance collection with the debut of the Dual Time GMT Resonance Rose Gold. Rendered for the first time in a 39 mm 18K rose‑gold case, the timepiece introduces a warm and elegant reinterpretation of the brand’s technically driven design language. Limited to 50 pieces worldwide, this edition pairs the Maison’s signature resonance innovation with a rich new aesthetic personality, blending contemporary elegance with mechanical sophistication.

A New Expression of Design & Craftsmanship
The new Rose Gold edition distinguishes itself through its interplay of warm tones and finely executed textures. The 18K rose‑gold case forms a glowing frame around the black‑gold grenage dial, a surface enriched by depth, contrast, and granular refinement. The dial’s twin layouts—each dedicated to one time zone—are clearly defined by black azurage chapter rings, ensuring intuitive reading while maintaining the balanced symmetry that defines the Resonance line. The rose‑gold‑coloured, faceted and polished hands, together with matching applied indexes, elevate the aesthetic with a luxurious brightness. At six o’clock on each sub‑dial, polished and blackened steel sun-and-moon day/night discs add functional clarity and a poetic visual touch. Completing the ensemble is a matte anthracite alligator strap accented with grey stitching and secured with a matching 18K rose‑gold pin buckle, creating a cohesive, modern, and refined profile.

The Science of Movement: Calibre ARF22
At the heart of the watch lies Armin Strom’s hand‑wound, in‑house Calibre ARF22, a movement defined by the brand’s patented resonance clutch system. This mechanism couples two independent balance wheels and allows them to synchronise through resonance, a natural physical phenomenon that enhances chronometric stability. What might otherwise remain a theoretical curiosity is transformed into a practical complication: each regulating organ governs its own time display, enabling two entirely independent time zones. Each dial also features a corresponding day/night indicator, making the watch particularly intuitive for world travellers. Operating at 3.5 Hz (25,200 vph) and offering a 42‑hour power reserve, the ARF22 movement brings a dynamic, kinetic quality to the dial, where the twin oscillators interact in real time. The aesthetic presentation of the movement reflects haute horlogerie values, with meticulous hand‑polished bevels, black‑polished steel components, circular graining, perlage, and Côtes de Genève on full display through sapphire crystals on both sides. In keeping with Armin Strom tradition, each watch is assembled twice, ensuring uncompromising mechanical integrity and flawless finishing.

Celestial Contrast: Armin Strom Dual Time GMT Resonance Aventurine

Armin Strom presents a new interpretation of its Dual Time GMT Resonance, distinguished by a dial crafted from aventurine—a material that captures the richness and mystery of a star-filled sky. Formed through a meticulous process that blends centuries-old glassmaking with modern precision, aventurine reveals a surface alive with light. The result is a dial that evokes a night sky in motion, creating a refined contrast with the architectural symmetry of the resonance movement. This celestial texture is enhanced by the warm tones of the movement: the rose gold-coloured mainplate adds depth beneath the dial-side display, while rose gold-coloured hands and applied indexes introduce clarity and visual identity. Together, these elements create a balanced interplay between cool luminosity and warm mechanical presence. Housed in a 39 mm stainless steel case and paired with a dark grey alligator strap, the Aventurine edition offers a contemporary and restrained frame, allowing the dial's dimension and the movement's symmetry to take centre stage.

Resonance Across Time Zones
Powering the watch is the manual-winding manufacture calibre ARF22, entirely designed, developed and produced in-house. Its patented resonance clutch—a signature Armin Strom innovation—synchronises two independent regulating systems, allowing both balance wheels to oscillate in perfect harmony. This constant interaction elevates chronometric stability, transforming a rare physical phenomenon into a practical advantage. Each time zone features its own hours, minutes and day/night indicator, offering intuitive functionality for travellers. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the ARF22 unites scientific ingenuity with everyday usability.

Finishing in Depth
Visible through sapphire crystals on both sides, the movement reveals Armin Strom's signature open-worked architecture and hand-finishing. The rose gold-coloured mainplate establishes a warm, luminous foundation on the dial side, while matching gear-train bridges on the reverse side echo this tone, creating a cohesive visual language. This harmony of colour and structure accentuates depth and contrast, reinforcing the three-dimensional expression of the calibre and the brand's commitment to the Science of Movement. On the dial side, the mirror-polished balance bridge, finished with hand-bevelled edges, stands out as a focal point, its steel surface catching the light in striking counterpoint to the warm rose gold-coloured mainplate beneath. Rhodium-coated and steel components introduce a refined metallic grey tone, balancing the overall composition. Additional hand-polished bevels, black-polished elements, circular graining and perlage enrich the composition, while the reverse side features Côtes de Genève, further emphasising the movement's refinement. As with all Armin Strom timepieces, each watch is assembled twice to ensure both mechanical precision and finishing excellence.

The new Dual Time GMT Resonance Aventurine is offered in a strictly limited edition of 15 pieces.

Chronoswiss Unveils the Neo Digiteur Chronos: Time Carved in Solid Gold

Chronoswiss is proud to announce the launch of the Neo Digiteur Chronos, an extraordinary evolution of one of the brand’s most unconventional creations. Inspired by the original handless Digiteur introduced in the early 2000s by founder Gerd-Rüdiger Lang, this edition transforms a radical mechanical rebellion into a sculpted gold masterpiece. Housed in a tailored 48mm x 30mm rectangular case made from solid 5N gold (65g) and completely hand-engraved at the Atelier Lucerne, the watch depicts Chronos—the ancient Greek god of time—holding a mythological hourglass.

Rather than utilizing a traditional dial, the watch seamlessly integrates three precise apertures into the sculpted gold scene. The passage of time is visually poetized: the jumping hour appears in Chronos’ scythe at 12 o'clock, the sweeping minute disc flows through the upper chamber of the hourglass, and the continuous seconds rotate below in the lower chamber. Encircling the entire case and printed inside the black nubuck strap is a classic Greek meander pattern, an ancient symbol representing eternity and the infinite flow of time

At the heart of this handless digital regulator is the hand-wound Chronoswiss Caliber C.85757, equipped with an in-house developed jumping hour module. Visible through the rectangular sapphire crystal caseback, the movement operates at 3 Hz with a 48-hour power reserve and features exquisite rhodium plating, radial Côte de Genève, and hand-guilloché wheel bridges executed in Lucerne. Completed with a 5N gold pin buckle (4g), every technical detail underscores the brand's commitment to expressive high horology.

Strictly limited to only 33 pieces worldwide, each Neo Digiteur Chronos requires weeks of painstaking hand engraving, ensuring no two pieces are ever completely identical. As a rare fusion of ancient mythology, traditional hand craftsmanship, and avant-garde watchmaking, this collector’s creation represents a mechanical myth carved in gold. The Neo Digiteur Chronos is now available for inquiry through authorized Chronoswiss retailers and official channels.
