Rolex Lady-Datejust 28 28 mm 279383RBRWMDO Steel/Yellow Gold/Diamonds White Mother of Pearl

The Rolex Lady-Datejust 28 is one of the most enduring icons in fine watchmaking, a lineage that traces its roots to the original Datejust introduced in 1945 — the first self-winding wristwatch to display the date in a window on the dial. Over the decades, Rolex refined the Lady-Datejust into a 28 mm expression purpose-built for those who demand both horological excellence and understated luxury. Reference 279383RBRWMDO represents the current pinnacle of that evolution, combining every hallmark of the collection in a single, cohesive package.

The case of the 279383RBRWMDO measures a perfectly proportioned 28 mm in diameter and is constructed in Rolex's signature two-tone Rolesor — Oystersteel on the case flanks and Oyster bracelet center links, and 18k yellow gold on the bezel setting, crown, and bracelet outer links. Oystersteel is Rolex's proprietary 904L stainless steel alloy, renowned for its exceptional resistance to corrosion and its ability to take a mirror-bright polish that rivals precious metal. The combination creates a watch that is simultaneously sporty and opulent.

The diamond-set bezel is among the most captivating details of this reference. Rolex's skilled gem-setters hand-select and individually set each diamond for uniform brilliance, ensuring that the graduated sparkle around the bezel frames the dial with maximum impact. The dial itself is rendered in white mother-of-pearl, a material prized for its soft iridescent play of light that shifts subtly with every movement of the wrist. Together, the diamond bezel and mother-of-pearl dial create a watch that catches light from every angle, day or night.

Powering the Lady-Datejust 28 is a certified Swiss-made automatic movement regulated to Rolex's exacting Superlative Chronometer standards, which require accuracy to within plus or minus two seconds per day — a benchmark considerably more stringent than the official COSC chronometer certification. The movement is housed within the legendary Oyster case, which provides water resistance to 100 metres (330 feet), making this watch equally at home at a board meeting, a black-tie event, or an afternoon on the water. The Triplock crown ensures the case seals securely each time it is screwed down.

Worn on Rolex's classic Oyster bracelet — a three-link design that has defined wristwatch elegance since 1931 — the Lady-Datejust 28 ref. 279383RBRWMDO sits flat and secure on even the most slender wrist. The Oyster bracelet's alternating brushed and polished links mirror the two-tone Rolesor aesthetic of the case, and the concealed Crownclasp ensures a clean, uninterrupted look from every angle. The result is a watch of extraordinary wrist presence that feels effortlessly refined rather than ostentatious.
