Rolex Lady-Datejust 28 28 mm 279138RBRSDIXP Yellow Gold/Diamonds Silver

The Rolex Lady-Datejust 28 ref. 279138RBRSDIXP is one of the most refined expressions of a lineage that stretches back to 1957, when Rolex introduced the Lady-Datejust as the first self-winding waterproof wristwatch designed specifically for women. Over the decades the model has remained the gold standard of feminine Swiss luxury watchmaking, admired for its disciplined proportions, enduring design language, and the technical credibility that only Rolex can provide. Reference 279138RBRSDIXP sits at the pinnacle of the current Lady-Datejust 28 collection, combining precious metal, high jewelry craftsmanship, and everyday wearability in a single 28mm package.

The case of the 279138RBRSDIXP is crafted entirely in 18k yellow gold, Rolex's own proprietary alloy produced in-house to exacting standards of color consistency and durability. At 28mm the Oyster case is sized with deliberate elegance, hugging the wrist without overpowering it, and the polished and brushed surfaces catch light in the characteristically sophisticated Rolex manner. Water resistance to 100 meters (330 feet) is guaranteed by the screw-down Twinlock crown and the Oysterlock caseback, giving this jewel-set watch a robustness that purely decorative pieces cannot match.

The bezel is lavishly set with brilliant-cut diamonds, each individually selected and set to ensure uniform brilliance around the full circumference of the case. The silver dial is clean and luminous, anchored by the signature diamond IX marker that gives this specific reference its "SDIXP" suffix designation. The dial's restrained layout allows the gem work to take center stage while preserving the immediate legibility that defines every Datejust, including the date window framed by Rolex's characteristic Cyclops lens on the crystal.

Power comes from a Rolex-certified automatic movement, a self-winding caliber manufactured entirely within Rolex's own manufacture in Geneva and Biel. Rolex movements at this tier are chronometer-certified by the Swiss Official Chronometer Testing Institute (COSC) and then subjected to Rolex's own even more stringent in-house precision testing before leaving the manufacture. The result is a movement whose daily accuracy is held to tolerances tighter than the COSC standard, housed in a case that protects it from dust, moisture, and the rigors of daily life.

On the wrist the 279138RBRSDIXP is completed by the President bracelet, an exclusively Rolex creation introduced in 1956 and reserved for the brand's highest-tier precious-metal references. Its three-piece semi-circular links in 18k yellow gold flow seamlessly from the lugs and secure via the concealed Crownclasp, combining the supple drape of a high jewelry bracelet with the security demanded of a daily wear timepiece. The overall effect is one of effortless luxury: diamonds, gold, and Rolex engineering unified in a watch that transcends trend.
