DANIEL ROTH Extra Plat Rose Gold Skeleton

The year 2026 marks a momentous milestone for Moritz Grossmann as we celebrate the 200th anniversary of our founder’s birth. Moritz Grossmann was not only a master horologist but a visionary scientist and author who forever changed the landscape of Glashütte watchmaking. To commemorate his bicentenary, we are proud to unveil the TREMBLAGE Gold anniversary edition, a tribute that bridges his 19th-century spirit with the pinnacle of modern artisanal watchmaking.

This exceptional release introduces two limited editions, crafted in 750/000 rose gold and 950 platinum, with each variant strictly limited to just eight pieces worldwide. The soul of these timepieces lies in the solid rose gold dial, which has been meticulously hand-engraved using the rare "tremblage" technique. This traditional method involves a master engraver using a specialized burin to create a multi-directional, finely textured matte surface, resulting in a mesmerizing play of light that serves as a backdrop for the raised, hand-polished numerals.

The movement powering these anniversary models is the exquisitely finished Calibre 100.1 manual-winding movement. In a direct nod to the founder's legacy, the balance cock features a unique hand-engraved "1826," marking the year of Grossmann’s birth. Every component, from the heat-annealed brown-violet screws to the hand-carved pillars and German silver plates, reflects our commitment to "Schönstes deutsches Handwerk"—the finest German craftsmanship.

With the TREMBLAGE Gold edition, we do not simply replicate history; we evolve it. These watches embody the same pursuit of technological perfection and aesthetic brilliance that Moritz Grossmann championed two centuries ago. We invite you to discover these masterpieces, which stand as a testament to a heritage that continues to inspire every movement we create and every hand-finished detail we produce in our Glashütte manufactory.

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.

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.
