Roger Dubuis Quatuor Carbon 48mm

Roger Dubuis presents the Quatuor Carbon 48mm, reference RDDBEX0673, a limited edition with a 48 mm carbon case. The case measures 10.6 mm thick and pairs with a sapphire crystal treated with an antireflective coating. Inside, the manual-winding calibre RD101 drives four balances through a system of differentials designed to compensate for the effects of gravity, a construction protected by three patents. The movement is fully skeletonised and visible through a sapphire display back, with the power reserve of 40 hours shown on the dial. Only 590 components make up the calibre, which carries the Poinçon de Genève certification. The case closes on a stainless steel folding clasp finished in black DLC. Water resistance stands at 30 metres.
