Roger Dubuis Quatuor Carbon 48mm

Roger Dubuis presents the Quatuor Carbon, reference RDDBEX0673, a limited edition of eight pieces with a 48 mm carbon case. Inside, the manual-winding calibre RD101 uses four balances and five differentials to average their rates. The skeletonised movement carries the Poinçon de Genève certification and has circular-grained plates and bridges with NAC coating. A power reserve display indicates the remaining energy from its 40 hour reserve. An anti-reflective sapphire crystal covers the front, and the black DLC titanium caseback has a sapphire window. Water resistance is rated to 30 metres.
