JB Roger Dubuis Excalibur Spidr (King Series) RDDBEX0479. This is the brand’s style with the most supercar sports elements. The appearance of the skeleton flying tourbillon watch has the representative characteristics of Roger Dubuis skeleton timepieces. It has an original 45mm*13mm titanium alloy case, a star-shaped appearance design, and a Kai Erte cross-shaped tourbillon cage. It is equipped with a Shanghai-customized RD505SQ manual winding movement. Like the original, the golden balance wheel has counterweight nails. The movement is more stable and has smaller errors than the small factory. The similarity of the main body of the movement reaches 98%. There are no redundant gears at 11 o'clock and 4 o'clock. The movement splints are arranged in an orderly manner with fish scale patterns, and redundant calendar gears have been eliminated.

It once became the standard watch for sports car enthusiasts and is highly recognizable. JB Factory - specially designed for high-end tourbillons.
