Datejust 31 Dark Grey Diamond Dial Diamond Bezel Steel 18KT Yellow Gold Oyster M278383RBR-0021

The Rolex Lady-Datejust 31 Reference M278383RBR-0021 is a luxurious and contemporary timepiece, perfectly balancing the classic two-tone aesthetic with dazzling diamond embellishment. This model features a sophisticated Dark Grey Dial set with diamonds, a magnificent Diamond-Set Bezel, and the robust Oyster bracelet, all presented in the iconic Rolesor Yellow Gold design (Oystersteel and 18K Yellow Gold).

The watch features a robust monobloc middle case in durable Oystersteel (Stainless Steel), ensuring reliability and strength in the mid-size 31 mm size. The case is water-resistant to 100 metres (330 feet), secured by the screw-down Twinlock winding crown.

The case is framed by the highly luxurious Diamond-Set Bezel. The ‘RBR’ (Rolex Briolette-cut Rims) or similar codes often indicate an enhanced diamond setting, where the brilliant-cut diamonds are precisely set edge-to-edge in solid 18K Yellow Gold, maximizing the watch’s brilliance and light reflection.

The timepiece is fitted with the robust, three-piece link Oyster bracelet, known for its strength and slightly sportier appearance compared to the Jubilee. Crafted in a two-tone Rolesor Yellow Gold style, the outer links are in satin-finished Oystersteel while the center links are in polished 18K Yellow Gold. The bracelet fastens securely with the folding Oysterclasp, which includes the Easylink 5 mm comfort extension link.

Key Features

The centerpiece is the sophisticated Dark Grey Diamond Dial. This deep, slate gray color is executed with a sunray finish, providing a dramatic and elegant backdrop for the gold elements and the diamond hour markers.

The hours are marked by 10 brilliant-cut Diamond Hour Markers (with the Rolex Crown at 12 o’clock and a date window at 3 o’clock), meticulously set in 18K Yellow Gold surrounds. The date is displayed at 3 o’clock, magnified beneath the Cyclops lens.

Under the dial lies the high-performance Calibre 2236 movement. This self-winding mechanical movement incorporates the patented Syloxi hairspring, providing exceptional performance, accuracy, and reliability, and is certified as a Superlative Chronometer, completing this distinguished timepiece.
