Rolex delivers spectacular design by combining the illumination of rainbow jewels with rose gold Rolex architecture. The Cosmograph Daytona was created to master the speed of timekeeping by featuring a chronograph, a 30-minute counter, and stop-seconds for a precise time setting. It comes with a 40mm rose gold case that has a screw-down case back, a scratch-resistant sapphire and features a bejeweled 18K rose gold bezel. Enclosed in the case are the 4130 Caliber that has bidirectional self-winding via Perpetual rotor, a-2/+2 sec/day precision and a 72-hour power reserve. The dial is rose gold, diamond-encrusted with rainbow-jeweled index hour indicators and three rose gold sub-dials. The bezel features a pave design of rainbow-colored jewels. The oyster bracelet is made of 18-carat rose gold and the center links are encrusted with diamonds. It is topped off by a bedecked rose gold oyster lock safety clasp. It has a water resistance of 100 meters (330 feet).
