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

The Rolex Lady-Datejust 28 is one of the most enduring icons in watchmaking history, tracing its lineage directly 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 the Lady-Datejust has refined that blueprint into a proportionally precise 28mm case designed specifically for the wrist, preserving every functional and aesthetic virtue of its larger siblings while delivering an unmistakably feminine presence. Reference 279384RBRSDO represents the current generation of that tradition, combining Rolex's proprietary Oystersteel with 18k white gold to create a case that is simultaneously sporty and luxurious.

The 28mm Oyster case of the 279384RBRSDO is a study in Rolex engineering discipline. Oystersteel, drawn from the 904L family of alloys, resists corrosion and polishes to a brilliance that ordinary stainless steels cannot match. White gold accents on the crown and case architecture introduce warmth and contrast, while the screw-down Oyster crown—a Rolex hallmark—ensures the movement remains sealed against the elements. The result is a watch that can move from boardroom to weekend without hesitation.

At the heart of the dial, the silver surface is clean and luminous, punctuated by the signature diamond IX marker that gives reference 279384RBRSDO its distinctive identity. The diamond-set bezel frames the dial in a continuous ring of brilliant-cut stones, catching light from every angle and elevating the piece unmistakably into the luxury tier. Rolex's gem-setting ateliers select and place each stone individually, holding them to strict standards of cut, clarity, and uniformity—a level of craft that is visible the moment you see the watch under natural light.

Powering the Lady-Datejust 28 is a Rolex-certified automatic movement, a self-winding caliber that keeps time with chronometric precision. Rolex submits every movement to rigorous in-house testing before casing, ensuring the watch meets its standard of accuracy. The Oyster bracelet—iconic in its three-link construction—integrates seamlessly with the case and is fitted with a concealed folding clasp, delivering security and comfort in equal measure. On the wrist, the 28mm diameter sits elegantly without overwhelming smaller proportions, making it a natural choice for daily wear or special occasions.
