Roger Dubuis Excalibur Spider Countach White Mineral Composite Fiber 47mm

The Roger Dubuis Excalibur Spider Countach White Mineral Composite Fiber 47mm, reference RDDBEX0988, has a 47 mm case built in mineral composite fibre. The case measures 10.4 mm thick. A sapphire crystal with anti-reflective coating covers the dial, and a titanium open case back reveals the movement in sapphire as well. Inside is the manual-winding calibre RD112, a skeletonized double flying tourbillon set at a 90 degree V-shape angle, carrying 72 hours of power reserve and certified with the Geneva Seal. Only 8 pieces of this limited edition were made. The watch is fitted to a white rubber strap with a folding titanium clasp. Rated to 50 metres, the case keeps its water resistance despite the open architecture of the dial.
