Roger Dubuis Excalibur Spider Minute Repeater Monotourbillon carbon 47 mm

Roger Dubuis presents the Excalibur Spider Minute Repeater Monotourbillon Carbon, reference RDDBEX1042, in a 47 mm carbon case. The self-winding calibre RD107 combines a flying tourbillon with a minute repeater and uses a double micro-rotor. The movement carries Poinçon de Genève certification. A sapphire crystal with anti-reflective coating covers the dial, and a sapphire display back reveals the mechanism. The black rubber strap has a Rubber Tech inlay, black and blue stitching, and a titanium triple folding clasp with a black DLC cover. This is a unique piece. Water resistance is rated to 30 metres.
