Roger Dubuis came to Watches and Wonders Geneva 2026 with a single, cohesive idea: “Movements of the Sky.” That theme runs through every new release, from an accessible steel calendar watch right up to a one-of-a-kind central tourbillon. Six novelties, six distinct personalities. Here is a short but detailed look at each.
Excalibur Biretrograde Calendar Cosmic Blue
The dial builds across seven levels, all united by the Maison’s new Cosmic Blue colour. A double-surface flange carries a broad azuré finish on top and opaline on the side, both coated in Cosmic Blue. Sun-brushed ecliptic counters display the day and date retrograde arcs, and rhodium-plated hour markers hold white Super-LumiNova inside their slots. A sun-brushed main plate module and a circular-brushed dial ring complete the layering effect.
Inside, the automatic RD840 calibre delivers 60 hours of power reserve. Its sculpted oscillating weight draws from the Maison‘s very first 1996 design. Every component receives hand-decoration across 14 finishing techniques, including wheel-bevelling, Côtes de Genève, perlage, and mirror polishing, earning Poinçon de Genève certification. The 40mm case is 316L stainless steel, finished with a combination of polishing, shot-blasting, and satin-brushing. It ships with a multi-link steel bracelet and a blue rubber strap as an alternative.
Excalibur Biretrograde Perpetual Calendar
Nine dial layers introduce the new Astral Blue colourway. Ecliptic counters cut in Astral Blue mother-of-pearl carry polished angles, and the month disc is also in mother-of-pearl. The main moon phase disc uses aventurine with a domed 18K pink gold moon that is laser-engraved for texture. Inner angle finishing, one of the rarest techniques in high horology, appears 14 times on the w-shaped retrograde bridges at 3 and 9 o’clock.
The new self-winding RD850 calibre counts 435 components, offers 60 hours of power reserve, and introduces a month corrector for easier regulation. Its astronomical moon phase follows the Moon’s orbit at 29 days, 12 hours, and 45 minutes, and stays accurate for approximately 122 years before needing its first single-click adjustment. Sixteen finishing techniques across the movement support Poinçon de Genève certification. The 40mm case is in 18K pink gold, paired with an Astral Blue calfskin strap.
Excalibur Perpetual Calendar Quatuor
The open-worked dial keeps the four balance wheels as the visual centrepiece, surrounded by a symmetrical perpetual calendar layout displaying days, date, months, and leap year counters. Blue accents on the flange and calendar counters nod directly to cobalt’s natural colour. The patented double-180° power reserve indication at 9 o’clock performs a theatrical sweep as both the hand and indicator move simultaneously at different speeds.
The RD116 calibre packs 758 components and three patents into one movement, combining gravity compensation via four balance wheels tilted in pairs at 90° and connected through five differentials, with a full perpetual calendar. Fourteen decoration techniques are performed by hand on each component at the Geneva Manufacture. Limited to just 8 pieces. The 48mm case uses Cobalt Chrome (Cartech® Micro-Melt® Biodur® CCM®), the same aerospace-grade alloy Roger Dubuis has used as a signature material since 2017. A blue calfskin strap with the Quick Release System completes the watch.
Excalibur Brocéliande: Dawn Rose & Twilight Blue
On the sapphire dial, craftspeople applied an ivy pattern in gold with leaves in finely cut and hand-polished mother-of-pearl. Three mobile parts of the movement, visible through the glass, also carry ivy decoration. Two freely rotating sapphire discs flank the micro-rotor, evoking wind moving through treetops. The Twilight Blue variant takes on a translucent blue varnish and white mother-of-pearl leaves, and the Dawn Rose version adds a diamond-set bezel with coloured varnished leaves in yellow, pink, and red.
The new RD721SQ is an automatic skeletonised calibre running at 28,800 vph with a 72-hour power reserve. Its tungsten-and-gold micro-rotor integrates cleanly into the open architecture. Bevelled and sandblasted bridges, rimmed wheels, rounded pinions, and rolled pivots all receive 14 hand-applied finishing techniques for Poinçon de Genève certification. The 38mm case is in 18K rose gold with the three signature Excalibur horns, a satin-finished body, crown guards, and polished bevelled lugs. Limited to 88 pieces per colourway.
Excalibur Lady of the Lake
The Sovereign Grey dial layers a white mother-of-pearl centre enclosed in gilded brass over a dark rhodium-coated plate with a sunray finish. Rose gold sword-shaped hands mark the time against a white-and-grey background. At 6 o’clock, a small seconds counter carries snailed decoration, and three-dimensional rose gold indexes with grey lacquer at centre create a tone-on-tone effect on the two-sided flange.
The automatic RD830 calibre has 183 components with Côtes de Genève on the main plate and snailed finishing throughout. An open-worked oscillating weight in 22k gold provides a visual focal point through the sapphire caseback. The jewel-shaped 36mm rose gold case holds a fluted bezel set with 48 diamonds. A Sovereign Grey alligator strap with a pearled effect and rose gold pin buckle is included and interchangeable.
Excalibur Moonlight – Rarities Programme
The four-level dial is a full celestial theatre. A blue CVD-treated brass flange at the periphery carries rhodium-plated indexes filled with black Super-LumiNova. A rotating hour disc in translucent Murano-type glass displays all twelve zodiac constellations in luminescent paint. The minute disc, also in Murano-type glass, carries astral motifs and a luminescent moon phase representation. A lunar surface appliqué on the 1-minute tourbillon cage rotates at the rhythm of the seconds. The sapphire caseback is laser-engraved with Milky Way-inspired dots, each hand-filled with luminescent material.
The Poinçon de Genève certified RD115 central mono-tourbillon has 283 components and 72 hours of power reserve, beating at 3Hz. Its planetary gear train with differential and its push-button clip-release time-setting mechanism are each protected by a separate patent. Nineteen decoration techniques are visible throughout the calibre, including perlage, Côtes de Genève, anglage, and constellation motifs in silver powdered varnish transfer on the barrel cover. The position of those constellations can be configured to match the owner’s birth date. The 45mm black DLC titanium case sits on a midnight blue calfskin strap. One unique piece.
Final Thoughts
Roger Dubuis confirmed at Watches and Wonders 2026 that its range covers a remarkably wide spectrum of ambition and price. The entry point is the Excalibur Lady of the Lake at €41,600, followed by the Cosmic Blue Biretrograde Calendar in steel at €45,500. The Excalibur Brocéliande sits at €97,500 for the Twilight Blue and €104,000 for the diamond-set Dawn Rose. Moving higher, the Biretrograde Perpetual Calendar in pink gold commands €113,000. The Excalibur Moonlight from the Rarities programme carries a price of €351,000 for its unique-piece status and central tourbillon complexity. Finally, the Excalibur Perpetual Calendar Quatuor, limited to 8 pieces and cased in aerospace-grade Cobalt Chrome, tops the collection at €676,000. Taken together, these six releases show Roger Dubuis in sharp form: technically bold, aesthetically distinct, and firmly guided by the sky above.
