Rolex Lady-Datejust 31 31 mm 278383RBRCDO Steel/Yellow Gold/Diamonds Champagne

The Rolex Lady-Datejust 31 is one of the most storied dress watches in horological history, representing the refined continuation of the original Datejust—the world's first self-winding waterproof chronometer wristwatch to display the date in a window at 3 o'clock. Over decades, Rolex refined the Lady-Datejust into an ideal 31mm proposition that sits beautifully on a wide range of wrists, bridging the gap between the 28mm Lady-Datejust and the full 36mm Datejust. Reference 278383RBRCDO is a current-generation expression of that legacy, pairing Oystersteel with 18k yellow gold in the classic Rolesor combination that has defined aspirational watchmaking for generations.

At 31mm, the case strikes a confident yet delicate presence. The Oystersteel and 18k yellow gold construction means the midcase's cool, corrosion-resistant steel is warmed by gold crown, winding crown, and bracelet center links—a contrast that photographers and collectors alike find irresistible. The Oyster case itself is a sealed fortress, rated to 100 meters (330 feet) of water resistance, thanks to Rolex's screw-down Triplock crown and screwed case-back—engineering rarely found in watches of this dressy character.

The dial of ref. 278383RBRCDO is finished in champagne, a tone that shifts from pale gold to warm honey depending on the light, lending the watch an almost jewelry-like warmth. It complements the diamond-set bezel perfectly—a bezel in which precisely graded diamonds are pavé-set to catch and scatter light from every angle. Together, the champagne dial and diamond bezel create a watch that moves effortlessly from boardroom to black-tie.

Powering the watch is a Rolex automatic movement, the brand's hallmark of precision and self-sufficiency. Rolex automatic movements are built and certified as chronometers, meaning they meet or exceed COSC accuracy standards before receiving additional in-house testing. The result is a movement that requires no manual winding under normal wearing conditions and delivers the date complication the Datejust line is celebrated for.

The Oyster bracelet completes the package with its three-piece link architecture, offering a secure, comfortable fit. The bracelet's center links in 18k yellow gold mirror the case's Rolesor aesthetic, while the outer links in Oystersteel add structural resilience. The Oysterlock safety clasp ensures the bracelet stays firmly in place during any activity.
