Rolex Datejust 31 31 mm 278344RBRWMOPDJ Steel/White Gold/Diamonds White Mother of Pearl

The Rolex Datejust is one of the most enduring and recognizable watch families in horological history, introduced in 1945 as the first self-winding wristwatch to display the date in a window on the dial. Across eight decades the Datejust has remained the definitive expression of Swiss watchmaking elegance, evolving through generations of materials and sizes while preserving the unmistakable aesthetic that made it iconic. The 31mm Datejust occupies a sweet spot in the collection, sized to wear beautifully on a wide range of wrists and appealing equally to those who prefer a refined mid-size profile.

Reference 278344RBRWMOPDJ represents one of the most opulent expressions within the current Datejust 31 lineup. The case is built from Rolex's proprietary Oystersteel—an exceptionally corrosion-resistant 904L stainless steel—combined with 18k white gold on the bezel, crown, and mid-links of the bracelet, creating the signature Rolesor two-tone aesthetic in its coolest, most luminous form. Water resistance is rated to 100 meters (330 feet), underpinned by the screw-down Oyster crown that has protected Rolex movements since 1926.

The dial is the centerpiece of this reference: a white mother-of-pearl surface that shifts and shimmers with light, each example unique in its iridescent pattern. Diamond hour markers punctuate the dial with precision-set stones, and the domed 18k white gold bezel is fully set with brilliant-cut diamonds that encircle the dial in continuous sparkle. Together these elements create a watch that is simultaneously a serious timepiece and a piece of fine jewelry.

Powering the watch is a Rolex-certified automatic movement housed within the Oyster case, delivering the reliability and precision Rolex is globally renowned for. Like all modern Rolex movements it is chronometer-certified by the COSC and further regulated by Rolex to their own more stringent standards, ensuring accuracy well beyond industry norms day after day.

The five-piece Jubilee bracelet—an original Rolex design launched alongside the very first Datejust—completes the 278344RBRWMOPDJ with characteristic suppleness and elegance. Its alternating polished and brushed links echo the two-tone character of the case, and the concealed Crownclasp provides a clean, seamless profile on the wrist. For those searching for a Rolex Datejust 31 diamond bezel mother-of-pearl for sale, this reference is among the most coveted configurations available.
