Rolex Lady-Datejust 28 28 mm 279171CSO Steel/Rose Gold Chocolate

The Rolex Lady-Datejust 28 is one of the most enduring icons in watchmaking, representing over seven decades of continuous refinement since Rolex introduced the Datejust in 1945—the first self-winding wristwatch to display the date in a window on the dial. The Lady-Datejust line has long served as the definitive dress watch for women who demand both elegance and Swiss horological pedigree. Reference 279171CSO sits squarely at the heart of this tradition, delivering the full Rolex Datejust experience in an impeccably proportioned 28mm case built for the modern woman.

The 28mm case of the 279171CSO is crafted in Rolex's proprietary Oystersteel—a 904L stainless steel alloy prized for its exceptional resistance to corrosion and its ability to take an extraordinarily deep, lasting polish—paired with 18k rose gold on the bezel and integrated bracelet elements. This two-tone Rolesor configuration, blending steel and rose gold, is a Rolex hallmark that has defined luxury sports-dress watches for generations. The result is a case that feels precious without being ostentatious, and robust without sacrificing femininity.

The dial is the soul of this reference: a rich chocolate tone that radiates warmth and depth under any lighting condition. Chocolate dials have become among the most coveted in the Rolex catalog, prized for their ability to complement rose gold accents in a way that cooler dial colors simply cannot. The 18k rose gold fluted bezel frames that dial with architectural precision, its serrated profile catching the light and providing a visual rhythm that anchors the entire design. Together, dial and bezel create a color story that is cohesive, luxurious, and immediately recognizable.

Powering the Lady-Datejust 28 is an authentic Rolex automatic movement, a self-winding mechanical caliber manufactured and regulated in-house to Rolex's exacting Superlative Chronometer standards. The watch is fitted on a five-piece-link Oyster bracelet in matching Oystersteel and rose gold, secured by Rolex's fold-over Crownclasp. The Oyster bracelet is one of the most copied and widely admired bracelet designs in horological history, renowned for its comfort, durability, and fluid drape on the wrist.

On the wrist, the 279171CSO strikes an ideal balance: large enough to read clearly and project a confident presence, yet refined enough to slip beneath a cuffed sleeve or complement an evening gown. The 28mm diameter has long been the standard for ladies' Datejust watches, ensuring an elegance that never feels overwhelming. Whether worn as an heirloom daily companion or reserved for special occasions, this reference transitions effortlessly from boardroom to ballroom.
