Rolex Datejust 31 31 mm 278384RBRBLURO Steel/White Gold/Diamonds Blue Rolex Datejust 31 31 mm 278384RBRBLURO Steel/White…

The Rolex Datejust is the archetype of the classic dress watch — introduced in 1945 as the first self-winding wristwatch to display the date in a window on the dial, it has remained in continuous production ever since and is widely regarded as the definitive reference point for elegant, everyday Swiss watchmaking. The 31mm size sits at the heart of Rolex's mid-size Datejust offerings, proportioned to suit a wide range of wrists while retaining every detail of the full-size collection. Reference 278384RBRBLURO represents the Datejust 31 at its most glamorous, combining precious materials and gem-setting with the robust Oyster DNA the line is built upon.

The case of the 278384RBRBLURO is crafted from a combination of Oystersteel — Rolex's proprietary 904L stainless steel, chosen for its exceptional corrosion resistance and ability to take a deep, enduring polish — and 18k white gold, a pairing that places this reference firmly in Rolex's two-tone luxury tier. At 31mm in diameter, the Oyster case is compact yet fully legible, and it carries a water resistance of 100 meters (330 feet), underscoring that Rolex never sacrifices utility for beauty.

The bright blue Roman numeral dial is the visual centerpiece of this reference. The rich, saturated blue creates an immediate impression of depth and luxury, while the Roman numerals lend a classical, almost formal register that distinguishes this dial configuration from the more common index-set alternatives. Blue dials have become among the most sought-after in the Datejust range, prized for their versatility — equally at home against a white dress shirt cuff or a casual sleeve.

Encircling the dial is a diamond-set bezel, one of the most coveted options in the Datejust 31 lineup. Each diamond is individually selected and set by Rolex craftspeople, adding a continuous arc of brilliance that catches and reflects light from every angle. The combination of the diamond bezel, white gold and steel case, and blue Roman dial makes the 278384RBRBLURO an exceptional piece for special occasions as well as elevated everyday wear. The watch is completed by the iconic Oyster bracelet, Rolex's most versatile and enduring bracelet design, renowned for its robustness, comfort, and seamless integration with the Oyster case.

Powering this Datejust 31 is a Rolex automatic movement, the product of the brand's in-house manufacture philosophy — every movement is developed, produced, and regulated entirely within Rolex's own facilities in Geneva and Bienne. Rolex movements are chronometer-certified by the COSC and subsequently tested to Rolex's own more stringent standards, ensuring precision and long-term reliability that underpins the brand's reputation.
