Roger Dubuis Excalibur Spider Minute Repeater Monotourbillon carbon 47 mm

Roger Dubuis presents the Excalibur Spider Minute Repeater Monotourbillon carbon 47 mm, reference RDDBEX1042, in a 47 mm carbon case. The case measures 10 mm thick and pairs with a sapphire crystal treated with an anti-reflective coating. Self-winding calibre RD107 drives the watch, combining a flying tourbillon with a minute repeater and running on a double micro-rotor for 60 hours of power reserve. The movement carries the Geneva Seal, a mark reserved for the most demanding finishing standards in Haute Horlogerie. This example is a limited edition, one of 558 pieces, and its display back shows the mechanism through sapphire. The black rubber strap closes with a titanium folding clasp finished in black DLC. Roger Dubuis rates the case to 30 metres.
