Roger Dubuis Excalibur Double Tourbillon

Roger Dubuis presents the Excalibur Double Tourbillon, reference RDDBEX1131, with a 45 mm white gold case measuring 14.66 mm thick. Baguette-cut diamonds cover the bezel, lugs, case sides, crown and star-shaped bridge. The manual-winding calibre RD108SQ is skeletonised and has two flying tourbillons linked by a differential. It carries Poinçon de Genève certification and provides a 72-hour power reserve. A sapphire display back reveals the movement from the reverse. A black calf leather strap closes with a triple folding clasp with a white gold cover and titanium blades. Limited to eight pieces, the watch is rated to 30 metres of water resistance.
