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

APRIL 29 2026    |    Novelties

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.

Celebrating 200 Years of Moritz Grossmann with the TREMBLAGE Gold

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.

Born of Tradition: Moritz Grossmann Unveils the HAMATIC Silver-Plated by Friction Anniversary Edition

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.

Mechanical Art Transversed: Moritz Grossmann Reveals the BACKPAGE Tremblage Anniversary Edition

The year 2026 marks a historic milestone for the Moritz Grossmann manufactory in Glashütte, celebrating the 200th birthday of its visionary founder and namesake, born on March 27, 1826. A genius watchmaker, scientist, author, and the initiator of the German Watchmaking School, Grossmann profoundly shaped the craft of horology and the fate of his hometown. Rather than merely duplicating 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 fourth anniversary special edition: the BACKPAGE Tremblage. Debuting on May 19, 2026, this launch presents an exclusive mechanical showcase for collectors—featuring a massive dial opening that reveals the magnificent inner workings of the movement from the front. Crafted with a luxurious three-part platinum case, the watch conceals a subtle celebratory nod on its reverse side: a balance cock delicately engraved with "1826", the birth year of Moritz Grossmann.

At the heart of this timepiece is the hand-wound manufactory calibre 107.0, a technical tour de force that essentially stands as a mirror image of the signature calibre 100.1. To allow components like the Grossmann balance, hand-engraved balance cock, and the triple-band snailing on the ratchet wheel to be admired on the dial side instead of being hidden on the back, the entire movement architecture had to be re-engineered. An additional wheel integrated between the crown wheel and the ratchet wheel reverses the rotation of the drive train, allowing the mirrored escapement and oscillation system to run perfectly in the correct direction.

The defining aesthetic highlight of this model is its German silver dial face, treated with the historic hand-worked tremblage engraving technique. By meticulously guiding a cutter back and forth in tiny trembling movements, master artisans create a vibrant, finely granulated, and uniform matt texture. The remaining dial elements define the watch's character, offered in either an expressive violet or a captivating "blue meteor" galvanized shade, framing the hour display from 11 to 5 o'clock. Strictly limited to 12 pieces per color variant worldwide, the models are completed with matching hand-annealed steel hands and hand-stitched alligator or kudu leather straps.
