Bokey TimeJB Roger Dubuis Excalibur Spider RDDBEX0479 is one of the brand’s most supercar-inspired models. This skeleton flying tourbillon watch features the representative openworked design of the Excalibur collection.
It adopts a 45mm × 13mm titanium case consistent with the original specifications, featuring a star-shaped structure and a Celtic cross–inspired tourbillon cage.
It is equipped with a Shanghai-customized RD505SQ manual-winding movement. The gold balance wheel includes weighted screws, providing improved stability and accuracy compared to standard versions. The movement achieves approximately 98% structural similarity to the original design.
The layout removes unnecessary gears at the 11 o’clock and 4 o’clock positions. The bridges are decorated with orderly circular graining, and redundant calendar components have been removed 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 a folding clasp.
This watch is bold, aggressive, and highly recognizable, making it a favorite among supercar enthusiasts for its strong wrist presence and distinctive design.
