Roger Dubuis Excalibur Spider Minute Repeater Tourbillon Carbon 47mm

Roger Dubuis presents the Excalibur Spider Minute Repeater Tourbillon Carbon 47mm, reference RDDBEX0774, in a 47 mm carbon case. The case measures 10 mm thick and pairs a titanium container with rubber inlays. A sapphire crystal with anti-reflective coating covers the skeletonised dial, and a matching sapphire panel on the caseback exposes the movement. Inside is the self-winding calibre RD107, a flying monotourbillon fitted with a minute repeater and certified with the Poinçon de Genève seal, offering 60 hours of power reserve. This is a limited edition of 558 pieces. The black rubber strap closes with a titanium folding clasp finished in black DLC. Rated to 30 metres, the case keeps a modest water resistance for a watch built around its complications rather than diving credentials.
