Carefully selected and passing rigorous tests, the gemstones used for these watches, along with the gold alloys from Rolex’s own foundry, the new Datejust Pearlmaster is set to shine with unique radiance. The new 39mm Oyster case made of 18K white gold guarantees water resistance to 100m, thanks to its fluted screw-down back and Twinlock double waterproof system for the screw-down crown. The scratch-resistant sapphire features Cyclops lens over the date, while bezel is set with a blue to fuchsia gradient of 48 baguette-cut sapphires. Complementing the bezel harmoniously, the astonishing red grape dial is set with diamonds in 18K gold settings, featuring center hour, minute and second hands, as well as instantaneous date in an aperture. Rolex’s newly developed automatic Perpetual 3235 caliber features blue Parachrom hairspring and new Chronergy escapement, as well the Perpetual rotor for bidirectional self-winding. The watch is held in place with the 18K white gold Pearlmaster bracelet with rounded five-piece links and a concealed deployment Crown-clasp.
