Rolex Lady-Datejust 28 28 mm 279138RBRMDJ Yellow Gold/Diamonds White Mother of Pearl

The Rolex Lady-Datejust has been the definitive expression of feminine watchmaking elegance since Rolex introduced the Datejust family in 1945, making it the first self-winding waterproof wristwatch to display the date in a window at 3 o'clock. Over decades, the Lady-Datejust evolved into its current 28mm generation, refining every proportion and material to suit the modern wrist while honoring a legacy admired across generations. Reference 279138RBRMDJ sits at the very top of this storied lineage, uniting Rolex's horological heritage with the extravagance of precious materials.

The 28mm case of reference 279138RBRMDJ is fashioned entirely in 18k yellow gold, a warm and timeless choice that radiates prestige under any light. Yellow gold has long been synonymous with classic Rolex dress watches, and on the Lady-Datejust its polished and satin-brushed surfaces create a play of texture that underscores the case's refined architecture. At 28mm the watch sits with quiet authority on the wrist — substantial enough to be noticed, delicate enough to wear with the finest attire.

The dial is one of the most captivating elements of this reference. White mother-of-pearl is harvested from the inner shell of mollusks, and no two dials are ever identical; each surface shifts through iridescent hues of cream, ivory, and pale silver depending on the angle and quality of light. Diamond hour markers punctuate the dial with additional brilliance, ensuring the watch catches the eye whether it is a candlelit dinner or an afternoon in bright sun. The result is a dial that feels organic, luxurious, and unmistakably Rolex.

Framing that extraordinary dial is a factory diamond-set bezel, in which individually selected brilliant-cut diamonds are set into the gold bezel by Rolex's own gem-setting artisans. This level of gem-setting is performed in-house to the same exacting tolerances Rolex applies to its movements, ensuring every stone is secure, level, and brilliantly matched. The five-link Jubilee bracelet — introduced by Rolex in 1945 alongside the original Datejust — completes the ensemble, draping the wrist in articulated 18k yellow gold links that are as comfortable as they are beautiful.

Powering reference 279138RBRMDJ is a Rolex-certified automatic movement, reflecting the brand's commitment to precision and reliability in every piece it produces. Rolex movements undergo rigorous testing beyond standard COSC chronometer certification before leaving the manufacture, and the Lady-Datejust 28 benefits from this same philosophy. The watch also offers water resistance to 100 meters (330 feet), a practical feature that speaks to Rolex's insistence that even its most jeweled creations remain genuine instruments.
