Roger Dubuis Excalibur The Kabuto Legacy: Twelve Samurai in 28 Pieces

A Considered Look

• Roger Dubuis Excalibur The Kabuto Legacy is a 45mm 18K pink gold timepiece limited to 28 pieces, featuring twelve individually hand-engraved samurai helmets in pink gold arranged around the dial, a central Edo Castle structure in deep blue CVD coating, and the in-house RD821 automatic calibre certified by the Poinçon de Genève.
• Each micro-sculpted Kabuto takes two to three days of skilled Métiers d’Art work to complete, with the front ornaments representing the most demanding elements of the craft.
• The RD821 calibre delivers 48 hours of power reserve, 172 components, and 14 distinct finishing techniques across every surface.
• Historical accuracy was guided by Professor Frederik Cryns, consultant on the Emmy-winning TV series Shōgun.

Design & Métiers d’Art

Twelve positions on the dial correspond to twelve bushō — samurai commanders whose alliance shaped Japan’s political order for over 250 years. Beginning at 12 o’clock with shōgun Tokugawa Ieyasu, whose Kabuto bears a fern frond symbolising prosperity and longevity, the circle continues clockwise through figures including Honda Tadakatsu (deer antlers at 1 o’clock, invoking divine protection) and Ii Naomasa (the crimson commander at 9 o’clock, whose towering golden tenshō crests identified him in the thick of battle). Each helmet is micro-sculpted in 18K pink gold with hand-engraved detail; the front ornaments, the most visible signatures of each bushō, are the most demanding elements to produce.

At the centre of the composition, Roger Dubuis has rendered Edo Castle in an abstract, layered construction. A deep blue CVD coating references the indigo dyes used in samurai garments and, later, in the wider tradition of Japanese textiles and art. The castle structure is built from 17 elements, combining polishing, bright polishing, circular brushing, and shot-blasting across every facet. Seven roof elements carry the blue CVD treatment; six receive a black PVD finish. The visual result is architectural rather than decorative.

Movement & Materials

The RD821 automatic calibre was chosen precisely because its open-worked architecture creates the space required to display the dial’s full sculptural content without obstruction. At 172 components and 33 jewels, it oscillates at 4 Hz and provides 48 hours of power reserve. Fourteen finishing techniques are applied across every component surface, satisfying the criteria of the Poinçon de Genève — the seal that defines Genevan haute horlogerie standards, recognised by the Fondation Haute Horlogerie community.

The 45mm pink gold case (18K, 750/1000) measures 16.87mm in thickness and is rated to 3 BAR. A blue enamel ring encircles the crown, and the bezel integrates a sapphire crystal ring. On the caseback, a blue-coated pink gold ring carries the twelve Kamon (clan crests) of the bushō, laser-engraved and protected by a sapphire glass that reveals the elaborately finished rotor. The blue calf-skin leather strap is constructed with stitched tiles to evoke samurai armour plate; it is interchangeable via Roger Dubuis’s Quick Release System, and a second strap is included.

Heritage & Academic Grounding

To ground the design in historical fact, Roger Dubuis worked directly with Frederik Cryns, Professor of Japanese History and academic consultant on the Emmy-winning television series Shōgun. His involvement shaped both the selection of the twelve commanders and the accuracy of each Kabuto’s iconography. As Professor Cryns states: “Samurai culture produced some of the most extraordinary wearable art in human history. That this tradition of master craftsmanship now meets the art of haute horlogerie feels entirely fitting. Both disciplines demand the same uncompromising pursuit of excellence.”

Roger Dubuis, established in Geneva in 1995 and operating as a fully integrated manufacture within the Richemont group, has built its identity on what it calls Hyper Horology: the conviction that technical achievement and expressive design are not competing values. The Kabuto Legacy extends that position into the territory of cultural scholarship, a step that sits credibly within the Excalibur collection’s established ambition.

Edition Context

The limitation to 28 pieces places this squarely in collector territory rather than the broader Excalibur range. For the GCC collector, the combination of Poinçon de Genève assurance, a fully documented historical narrative, and the visual scale of a 45mm pink gold case creates a clear proposition. The strap patina treatment, which the brand describes as resembling used armour, adds a material texture that distinguishes the piece further from the standard Excalibur line in both look and feel.
