Roger Dubuis Excalibur Monobalancier Cobalt

Roger Dubuis presents the Excalibur Monobalancier Cobalt, reference RDDBEX0969, a 42 mm case made from cobalt chrome. The case measures 5.95 mm thick, with a matching cobalt crown against the cobalt chrome flanks. A sapphire crystal with anti-reflective coating covers the skeletonized blue dial, and an open case back shows the movement from behind. Inside runs the self-winding calibre RD720SQ, finished to Poinçon de Genève standards and good for 72 hours of power reserve. This piece is part of a limited edition, and its openworked construction lets the 178-component architecture stand visible. A blue rubber strap with Rubber Tech inlay closes on a steel triple folding clasp. Water resistance reaches 100 metres.
