Lunar Chronograph Aurora

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 the HAMATIC Silver-Plated by Friction anniversary edition. This special timepiece introduces exclusive design details that pay tribute to the brand's origins, including an "1826" engraving on the balance cock and a vintage 1875 "M. GROSSMANN" logo on the dial. For the first time on a Hamatic model, clean Arabic numerals represent the hours, gracefully stepping in to replace the Roman numerals traditionally favored in previous iterations.

At the heart of the watch lies the exquisite manufactory calibre 106.0, which features a highly effective automatic winding system driven by a pendulum-style hammer weight. This "hammer automatic" mechanism masterfully reinterprets a historical concept with contemporary engineering, incorporating custom features like stop seconds for precise time setting and hand-finished decorations. The movement also proudly mirrors Grossmann’s original ingenuity through traditional hallmarks, such as a large balance wheel, raised screws, and fine handcrafted hands made of blue annealed steel.

The standout aesthetic achievement of this anniversary edition is its rare "silver-plated by friction" dial finish. This painstaking, entirely manual technique requires a master artisan to delicately brush the dial surface with specialized pastes and powders to achieve a fine-grained, velvet-like texture that softly diffuses light. Set in an elegant white gold case paired with a blue kudu leather strap, the HAMATIC Silver-Plated by Friction will be released on March 26, 2026, and is strictly limited to just 18 pieces worldwide.

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.

Following its global debut last night, Greubel Forsey is proud to unveil a new expression of the Balancier 3. Limited to just 22 timepieces, this latest edition continues the evolution of the movement first introduced in 2023, pushing the boundaries of hand-finishing by introducing a treatment never before executed at the Atelier: a frosted titanium bridge, hand-finished with a steel brush across its entire curved surface.

Housed in the signature 41.50mm Convexe titanium case, the Balancier 3 combines this innovative finishing with vibrant blue tones to create a three-dimensional landscape where high-performance chronometry meets unparalleled ergonomic design. The variable geometry of the case is engineered to follow the natural curvature of the wrist, while the multi-level openworked bridges provide a sense of visual lightness despite the movement's technical density.

Performance without compromise defines the heart of the Balancier 3, where technical density meets a striking sense of visual openness. This hand-wound movement is composed of 282 individual parts, featuring two series-coupled fast-rotating barrels that deliver a 72-hour chronometric power reserve. At its core, the in-house variable-inertia balance wheel measures 12.60mm in diameter and is meticulously fitted with six gold mean-time screws to ensure absolute precision.

The functional layout remains faithful to its original architectural concept, displaying hours and minutes on a suspended central bridge alongside a rotating small seconds disc. While the dial side offers a three-dimensional view of the mechanics, the movement side reveals a power-reserve indication integrated into the frosted titanium bridges. Every element, from the involute circle profile gearing to the olived-domed jewels, represents a singular vision of horological excellence and the "Art of Invention."

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.
