JUNE 05 2025    |    Novelties

Greubel Forsey unveils its new GMT Balancier Convexe. As the Earth takes centre stage within a newly reimagined amphitheatre, the hours, minutes, seconds, second time zone, and universal time indications become both companions and spectators to its quiet revolution.

– New 72-hour power reserve indicator seamlessly integrated into the dial.

Technical enhancements
– 496 components, 73 more than its predecessor.
– Inclined escapement suspended beneath polished steel bridge.
– Real-time rotating globe in layered amphitheatre.
– Sapphire disc on caseback with 24 cities, La Chaux-de-Fonds replaces Paris.

Exclusivity

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.

Chronoswiss Unveils the SPACE TIMER GRAVITY — A New Exploration of Mechanical Cosmos

Chronoswiss expands its avant‑garde Space Timer collection with the new SPACE TIMER GRAVITY, a 44mm mechanical creation inspired by the invisible yet powerful force of gravity. Limited to 50 pieces, the watch transforms cosmic phenomena into a visually architectural dial experience.

A Dial Where Light, Matter, and Mechanics Interact
The dial features a partly hand‑guilloché surface finished with a colour‑shifting CVD coating that transitions between deep green and oceanic blue depending on light — evoking the sensation of viewing a planet from orbit. A striking moon at 9 o’clock is produced through sophisticated laser work based on an original NASA photograph, revealing cratered textures with exceptional depth.

Floating above the landscape are transparent ITR2 hour and date rings that appear suspended in orbit. Beneath them, the exposed gear train is framed by a baby‑blue bridge, echoing the hue of the seconds hand and adding contemporary contrast to the cosmic scene.

A Case Built for Orbit
The 44mm matte‑grey stainless‑steel case delivers a modern, technical presence while allowing the dial’s dynamic surfaces to take centre stage. It pairs with a light grey nubuck leather strap for a refined, futuristic aesthetic.

The Engine Behind the Cosmos
Inside beats the Chronoswiss Caliber C.308, an automatic movement operating at 4 Hz with a 42‑hour power reserve. Mechanics remain proudly visible, emphasising the interplay between the unseen forces of gravity and the precise regulation of time.

A Limited Universe
Limited to 50 pieces worldwide, each SPACE TIMER GRAVITY captures the dance of light across its shifting dial, making every piece uniquely personal.

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.
