Unleashing a horological spectacle at Watches and Wonders Geneva 2026, Roger Dubuis debuted seven new watches that captivated audiences with their artistry, innovation, and mechanical mastery. In grand, dramatic style, each debut ranged from world-first complications to audacious artistry, haute horlogerie decorations, and a fresh perspective on women’s timepieces. The 2026 novelties share a common theme: they are visually captivating benchmarks of watchmaking métiers.

Headlining the novelties is the Excalibur Perpetual Calendar Quatuor, a feat of engineering and craftsmanship limited to just eight pieces. This watch features Roger Dubuis’ signature four-balance-wheel Quatuor system combined with a Perpetual Calendar, a first. Encased in a 48mm Cobalt Chrome case, it houses the Calibre RD116, protected by three patents and composed of 758 components, offering instantaneous gravity compensation through four tilted balance wheels.

The Excalibur Moonlight, is powered by the Poinçon de Genève–certified Calibre RD115 and features a patented planetary gear train, resulting in time displayed on a rotating Murano-type glass disc. Inspired by the night sky, the 45mm black DLC titanium case display features astronomical motifs including zodiac constellations, lunar imagery, and a rotating moon appliqué; the sapphire caseback features an engraving of the Milky Way. 

Inspired by the mythical magic of the Arthurian forest, the Excalibur Brocéliande returns in two 38mm editions: Dawn Rose and Twilight Blue, both crafted in 18K rose gold. These women’s pieces, limited to 88 pieces per edition, are powered by the skeletonised automatic Calibre RD721SQ, developed specifically for this line. With a 72-hour power reserve, the sapphire dial is adorned with mother-of-pearl ivy-leaf motifs and rotating sapphire discs, evoking a woodland wanderlust. 

Drawing from the legend of Viviane, The Mysterious Lady of the Lake, Roger Dubuis introduces a 36mm rose-gold watch with a green mother-of-pearl mosaic dial reminiscent of the mystical waters of Brocéliande. The dial consists of hand-lacquered green fragments, complemented by a diamond-set bezel and the automatic Calibre RD830, visible through the sapphire case back. Another version, Excalibur Lady of the Lake, features a Sovereign Grey dial with sword-shaped hands and a 48-diamond bezel, symbolizing strength, armor, and independence.

Showcasing the Maison’s technical bravado, the Excalibur Biretrograde Perpetual Calendar features the complex RD850 calibre, powering a self-winding movement that tracks day, date, month, leap year, and an ultra-precise moonphase accurate for 122 years. Its 40mm pink-gold case houses a movement with a nine-layered Astral Blue dial and a 60-hour power reserve, making this timepiece a masterwork of horological technicality.

The Excalibur Biretrograde Calendar Steel offers a relaxed expression of the brand’s signature complication. Presented in a 40mm stainless steel case with a multi-link bracelet, the watch features the day and date displayed via the Maison’s patented biretrograde system. Set against a Cosmic Blue dial, the open-worked design reveals finely finished components, combining technical refinement with modern, versatile elegance.
