Roger Dubuis Excalibur Biretrograde Perpetual Calendar

Roger Dubuis presents the Excalibur Biretrograde, reference RDDBEX1178, in a 40 mm rose gold case. The self-winding calibre RD850 drives the watch and holds a power reserve of 60 hours. The movement carries the Poinçon de Genève, and a sapphire display back reveals its finishing. This is a limited edition, produced in a run of 188 pieces. The watch is fitted to a blue calf leather strap secured by a rose gold folding clasp with Quick Release System. Rated to 100 metres, the case suits everyday wear without demanding special care.
