Roger Dubuis Excalibur Monotourbillon white gold

Roger Dubuis presents the Excalibur Monotourbillon white gold, reference RDDBEX0989, in a 42 mm white gold case. The case measures 6.9 mm thick and pairs with a sapphire crystal that also covers the display back. Inside, the manual-winding calibre RD512SQ carries a flying tourbillon and offers 72 hours of power reserve. The movement is fully skeletonised and bears the Geneva Seal, a mark of finishing reserved for movements made to that standard. This piece is part of a limited edition, a rare proposition even within the Excalibur line. A white calf leather strap closes on a titanium folding clasp with a white gold cover. Roger Dubuis rates the case to 100 metres.
