The new Oyster Perpetual Cosmograph Daytona, in 18 ct Everose gold, is adorned with gemstones.  In lieu of the emblematic tachymetric scale, the bezel features a gradation of 36 baguette-cut sapphires in rainbow hues. Eleven baguette-cut sapphire hour markers each match the colour of the corresponding gemstone on the bezel. The traditional chronograph counters are in pink Gold Crystals. The case is embellished with 56 brilliant-cut diamonds set into the lugs and crown guard. This new Cosmograph Daytona is equipped with calibre 4130, integrating a blue Parachrom hairspring produced by Rolex in an exclusive paramagnetic alloy, and offering a power reserve of approximately 72 hours.
