Roger Dubuis Excalibur Spider Huracán White Ceramic RDDBEX0947 Limited Edition 88 Pieces White Dial

Opening Context
The Roger Dubuis Excalibur collection represents one of the most expressive interpretations of contemporary haute horlogerie, combining traditional Swiss watchmaking with unconventional materials, architectural movements and a distinctly modern design language. Since its establishment in 1995, Roger Dubuis has developed an identity rooted in mechanical creativity and technical experimentation, often making the movement itself central to the appearance of the watch. The Excalibur Spider Huracán extends this philosophy through the manufacture’s collaboration with Lamborghini Squadra Corse, drawing inspiration from the engineering, materials and structural design of high-performance sports cars. The Ref. RDDBEX0947 captures this relationship particularly well, combining a 45 mm white ceramic composite fibre and titanium case with a skeletonised dial and automatic movement. Limited to 88 pieces, it represents a distinctive expression of Roger Dubuis’ approach to contemporary mechanical watchmaking.

Why This Reference Matters
The defining appeal of the Ref. RDDBEX0947 lies in the relationship between its automotive-inspired architecture and its exposed mechanical construction. Rather than treating the dial as a conventional surface, Roger Dubuis uses an openworked design that reveals the intricate structure of the movement beneath. The white skeletonised display creates a layered composition, with luminous hour markers providing clarity against the surrounding mechanical components. A date indication introduces practical functionality without significantly compromising the open architecture. The white ceramic composite fibre and titanium construction reinforces the technical identity of the watch, bringing together materials selected for their distinctive physical and visual properties. Beneath the dial sits the automatic Calibre RD630, an engine-inspired movement developed within the Excalibur Huracán family. Its twin-barrel construction provides an approximately 60-hour power reserve, while the distinctive movement architecture reflects the manufacture’s commitment to making mechanical engineering an integral part of the design. Produced as a limited edition of 88 pieces, the reference offers a particularly focused interpretation of the Excalibur Spider Huracán concept.

On the Wrist
At 45 mm, the Excalibur Spider Huracán has an unmistakably substantial presence, although its lightweight composite and titanium construction helps moderate the wearing experience. The broad case, openworked architecture and sharply defined surfaces create a watch that feels distinctly technical rather than conventionally elegant. Its white colour scheme gives the design a particularly striking appearance, with the skeletonised dial introducing depth and contrast as the exposed components interact with changing light. The luminous hour markers provide a practical reference against the complex mechanical background, while the date display adds everyday utility. A white rubber strap reinforces the sporting character of the watch, offering flexibility and comfort against the wrist. Secured by a titanium deployant clasp, the overall presentation feels cohesive, with the case, dial and strap working together as elements of a single contemporary design. It is a watch that makes no attempt to disguise its mechanical personality, instead inviting the wearer to appreciate the movement and structure from every angle.

Condition & Transparency
This example is configured with a 45 mm white ceramic composite fibre and titanium case, white skeletonised dial and white rubber strap with a titanium deployant clasp. The dial features luminous hour markers and a date display, with the exposed mechanical architecture forming an important part of its visual identity. It is powered by the automatic Calibre RD630, with an approximately 60-hour power reserve. The reference is described as a limited edition of 88 pieces, although the individual edition number and supporting documentation for this example have not been provided. No specific information regarding cosmetic condition, case refinishing, dial and movement originality, box and papers, provenance or previous servicing has been supplied, and these details therefore remain unconfirmed rather than assumed. For a watch of this construction, particular attention should be given to the condition of the composite case surfaces, integrity of the titanium components, preservation of the openworked movement architecture and correct operation of the date mechanism. The condition of the rubber strap, deployant clasp and documented mechanical history are also meaningful considerations. Water resistance should not be assumed without appropriate testing.

Why It Belongs in a Collection
The Ref. RDDBEX0947 suits a collector who appreciates the more experimental side of contemporary haute horlogerie, where traditional mechanical craftsmanship is expressed through unconventional materials and bold architectural design. Its appeal lies in the connection between the skeletonised movement, automotive-inspired construction and the distinct visual identity of the Excalibur Spider Huracán family. Unlike classical dress watches that emphasize restraint and traditional finishing, this reference celebrates exposed mechanics, technical surfaces and the relationship between watchmaking and high-performance engineering. Within a broader collection, it offers a strong contrast to more conventional sports watches and complicated timepieces, demonstrating how Roger Dubuis has developed a recognizable approach to modern mechanical design. Its limited production of 88 pieces adds specificity to the reference, although its lasting attraction rests primarily in the distinctive way it brings together material experimentation, mechanical architecture and contemporary styling.

Closing
The Roger Dubuis Excalibur Spider Huracán Ref. RDDBEX0947 demonstrates how contemporary watchmaking can draw inspiration from automotive engineering while maintaining a clear mechanical identity. Its white ceramic composite fibre and titanium case provide a technical foundation, while the skeletonised dial reveals the architecture of the automatic Calibre RD630 beneath. The white rubber strap completes the cohesive, performance-inspired design. Limited to 88 pieces, it represents a distinctive chapter in the Excalibur Spider Huracán collection, where mechanical creativity, unconventional materials and an unapologetically modern approach to watchmaking come together naturally.
