Roger Dubuis Excalibur Sorayama Monobalancier

Roger Dubuis presents the Excalibur Sorayama Monobalancier, reference RDDBEX1013, a titanium watch measuring 42 mm across. The case stands 5.95 mm thick and pairs with a sapphire crystal treated with anti-reflective coating. Inside is the self-winding calibre RD720SQ, a skeletonised movement bearing the Geneva Seal and offering 72 hours of power reserve. The open case back in sapphire crystal lets the sand-blasted plate and bridges show through. This is a limited edition, one of 178 pieces, with the skeleton architecture serving as its main visual complication. A full titanium bracelet completes the watch. Water resistance reaches 100 metres, courtesy of the titanium crown and case construction.
