Roger Dubuis Excalibur Monotourbillon Cobalt 42mm

Roger Dubuis presents the Excalibur Monotourbillon Cobalt 42mm, reference RDDBEX0838, a 42 mm case with a triple-lug design. The case measures 6.9 mm thick and carries the Poinçon de Genève seal, a mark reserved for movements finished to Geneva's own standard. Inside is the manual-winding calibre RD512SQ, openworked and hand-finished, running with 72 hours of power reserve. The skeletonised construction leaves the flying tourbillon fully exposed at the dial, its blue CVD coating and cobalt main material giving the movement a distinct tone. This is a limited edition, one of 88 pieces made. The blue calf leather strap closes with a titanium folding clasp fitted with the Quick Release System.
