Rolex Lady-Datejust 28 28 mm 279384RBRSRJ Steel/White Gold/Diamonds Silver

The Rolex Lady-Datejust 28 ref. 279384RBRSRJ is a masterclass in refined femininity and watchmaking precision. Introduced as an evolution of the iconic Datejust lineage — itself dating back to 1945 as the first self-winding waterproof chronometer wristwatch to display the date — the Lady-Datejust 28 was updated to its current 28mm proportions to sit gracefully on smaller wrists without sacrificing any of the model's celebrated presence. Reference 279384RBRSRJ sits among the most luxuriously appointed references in the current Lady-Datejust catalogue.

The case of the 279384RBRSRJ is constructed in a blend of Oystersteel — Rolex's proprietary 904L stainless steel alloy prized for its superior corrosion resistance and high-polish luster — and 18k white gold, a combination that elevates the watch well beyond standard steel sports references. At 28mm in diameter the Oyster case is classically proportioned, engineered to Rolex's exacting tolerances and sealed to provide water resistance suited to daily wear. The fluted crown and characteristic Oyster architecture give the case its instantly recognizable silhouette.

The diamond-set bezel is the jewel of this reference, literally and figuratively. Individually selected brilliant-cut diamonds are set around the entire circumference of the bezel, catching light from every angle and framing the dial with an unbroken circle of scintillation. This level of stone setting demands painstaking craftsmanship — each diamond must meet Rolex's strict criteria for cut, color, and clarity before it is certified for use on an Official Rolex Timepiece.

Beneath the diamond bezel lies the silver dial with Roman numerals, a dial configuration that speaks directly to classical haute horlogerie tradition. The Roman indices lend a legible yet decorative quality that complements the overall jeweled aesthetic perfectly. The dial is protected by a scratch-resistant sapphire crystal and completed by the characteristic Rolex date window at three o'clock — the feature that defines every Datejust regardless of generation. The five-link Jubilee bracelet, developed by Rolex specifically for the Datejust in 1945, drapes elegantly from the case and is widely regarded as one of the most comfortable and beautifully finished bracelets in watchmaking.

Powering the Lady-Datejust 28 is a Swiss-made automatic movement, regulated to chronometer standard by the Swiss Official Chronometer Testing Institute (COSC) and subsequently certified by Rolex itself as a Superlative Chronometer — ensuring accuracy of plus or minus two seconds per day in real-world conditions. The movement is self-winding, meaning regular daily wear keeps it perpetually wound without any manual intervention.
