Roger Dubuis Excalibur Monotourbillon Grey DLC Titanium

Roger Dubuis presents the Excalibur Monotourbillon Grey DLC Titanium, reference RDDBEX0889, a 42 mm case in dark grey DLC titanium. The case measures 6.9 mm thick and carries the Poinçon de Genève certification. Sapphire crystal covers the dial and the open case back, giving a view onto the skeletonised movement. The manual-winding calibre RD512SQ runs with a flying tourbillon and stores 72 hours of power reserve. This limited edition is capped at 88 pieces. It comes on a black calf leather strap fitted with a titanium folding clasp and Quick Release System. The case holds a 100 metre water resistance rating, generous for a piece built around an open-worked tourbillon.
