Rolex Lady-Datejust 28 28 mm 279173SDRIXJ Steel/Yellow Gold Silver

The Rolex Lady-Datejust is one of the most storied and recognizable watches in horological history, having defined the category of the elegant, date-displaying ladies' timepiece since its introduction in 1957—the first waterproof, self-winding, date-showing wristwatch sized specifically for women. Reference 279173SDRIXJ belongs to the current 28mm generation, which updated the Lady-Datejust line with a slightly larger case that strikes the ideal balance between refined proportion and contemporary wrist presence. The Oystersteel and 18k yellow gold construction—known within the Rolex catalog as Rolesor—has long been a signature combination, lending the watch both durability and warmth.

The case of the 279173SDRIXJ measures a delicate yet confident 28mm in diameter and is rendered in Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional corrosion resistance and high-polish potential. The yellow gold elements—most prominently the fluted bezel and bracelet center links—are crafted in 18k yellow gold, providing the luminous contrast that defines the two-tone Rolesor aesthetic. The fluted bezel itself is one of Rolex's most iconic design signatures, originally conceived as a functional tool for tightening the case and now a symbol of prestige recognized worldwide.

The silver dial of reference 279173SDRIXJ is a study in understated luxury. Its most distinctive feature is the diamond-set IX marker—a single brilliant-cut diamond replacing the nine o'clock index—which introduces a touch of fine jewelry sensibility without overwhelming the dial's clean architecture. The remaining hour markers and the date aperture at three o'clock maintain the classic Datejust legibility that professionals and collectors have relied upon for decades. The overall dial composition is polished, versatile, and unmistakably Rolex.

Powering the Lady-Datejust 28 is an automatic movement, ensuring the watch winds itself through the natural motion of the wearer's wrist. The Oyster case provides water resistance to 100 meters (330 feet), a practical specification that far exceeds the demands of everyday wear. The five-link Jubilee bracelet—invented by Rolex and debuted alongside the original Datejust in 1945—completes the watch with its characteristic elegance, draping gracefully around the wrist and echoing the two-tone materiality of the case.

From an investment and collecting perspective, the Lady-Datejust 28 in Rolesor with a fluted bezel and diamond marker occupies a sweet spot: it is a genuine Rolex with precious metal content and a diamond detail, yet it wears with the effortless versatility of a daily watch.
