Roger Dubuis Excalibur Spider Carbon 45mm

Roger Dubuis presents the Excalibur Spider Carbon 45mm, reference RDDBEX0752, a limited edition with a 45 mm carbon case. The case measures 4.28 mm thick, and the dial sits under a sapphire crystal treated with anti-reflective coating. A skeletonised RD509SQ movement drives the watch, wound by hand and carrying a flying tourbillon built from multilayer carbon, with 90 hours of power reserve. The construction bears the Genevian Seal, a mark few manufacturers can claim. A sapphire display back on the black DLC titanium caseback shows the open-worked plate and bridges. The watch rides on a black rubber strap with white Rubber Tech inlay, secured by a titanium folding clasp. Its rubber crown with carbon cover holds the case to a 50 metre rating.
