Roger Dubuis Excalibur Double Tourbillon

Roger Dubuis presents the Excalibur Double Tourbillon RDDBEX1131, a 45 mm case in white gold. The case measures 7.35 mm thick and is fitted with a sapphire crystal over an open, skeletonised dial. Baguette-cut diamonds cover the lugs, sides and crown, and the star-shaped bridge is set with diamonds as well. The manual-winding calibre RD108SQ drives a skeleton double flying tourbillon, with the two carriages linked by a differential and a power reserve of 72 hours; the movement carries the Poinçon de Genève certification. This example belongs to a limited edition of eight pieces. It is fitted to a black calf leather strap on a titanium folding clasp, itself set with diamonds. The case is water resistant to 30 metres.
