The Roger Dubuis Excalibur Spider RDDBEX0479 is one of the brand’s most supercar-inspired designs, showcasing a strong motorsport aesthetic. This skeleton flying tourbillon watch reflects the iconic openworked style that defines Roger Dubuis timepieces.
It features a titanium case measuring 45mm × 13mm, consistent with the original specifications. The design incorporates a signature star-shaped skeleton structure along with a Celtic cross–inspired tourbillon cage, creating a bold and highly recognizable look.
The watch is powered by a Shanghai-customized RD505SQ manual-winding movement. Like the original, it is equipped with a gold balance wheel featuring adjustable weight screws. Compared to standard factory movements, it offers greater stability and improved accuracy, with an overall structural similarity of up to 98%. The movement is optimized with no extra gears at the 11 and 4 o’clock positions. The bridges are neatly arranged and finished with perlage decoration, and the redundant calendar position has been removed for a cleaner mechanical structure.
The watch is fitted with a scratch-resistant sapphire crystal and a premium rubber strap made from imported Thai natural materials, offering excellent flexibility and refined craftsmanship. It is paired with a folding clasp for a secure and comfortable fit.
Bold, aggressive, and visually striking, this model stands out with exceptional wrist presence. It has become a popular choice among supercar enthusiasts thanks to its high recognition and distinctive skeleton design.
JB Factory focuses on high-end tourbillon watches, delivering timepieces that combine mechanical precision with strong visual appeal.
