Bokey TimeThe JB Roger Dubuis Excalibur Spider RDDBEX0479 is one of the most supercar-inspired designs in the Excalibur collection, featuring a fully skeletonized flying tourbillon with strong visual impact and a highly technical aesthetic.
It adopts a 45mm × 13mm titanium case consistent with original specifications, highlighted by a star-shaped structure and a Celtic cross–inspired tourbillon cage.
The watch is powered by a Shanghai-customized RD505SQ manual-winding movement. The gold balance wheel includes weighted screws, improving stability and timekeeping precision compared to standard versions. The movement achieves approximately 98% structural similarity to the original architecture.
The layout removes unnecessary gears at the 11 o’clock and 4 o’clock positions, while the bridges are decorated with orderly circular graining. Redundant calendar functions have been eliminated for a cleaner mechanical structure.
A scratch-resistant sapphire crystal protects the dial. The strap is made from imported Thai natural rubber, offering high flexibility and refined craftsmanship, paired with an original-style folding clasp.
Bold, aggressive, and highly recognizable, this model delivers strong wrist presence and has become a favorite among supercar enthusiasts.
