Roger Dubuis Excalibur Spider Flyback Chronograph

Roger Dubuis presents the Excalibur Spider Flyback Chronograph, reference RDDBEX1046, a 45 mm case in carbon. The dial sits under a sapphire crystal, with a black ceramic bezel carrying lacquered markings. Inside is the self-winding calibre RD780, a skeletonized chronograph movement with a column wheel and vertical coupling clutch, offering 72 hours of power reserve. Beyond the flyback function, the calibre drives a 120-degree rotating minute counter at 3 o'clock, an unusual departure from a conventional subdial. The movement carries the Geneva Seal and this piece belongs to a limited edition. A display back shows the finishing on the plate and bridges. Fitted to a black rubber strap with a titanium folding clasp, the case is rated to 100 metres of water resistance.
