Rolex Lady-Datejust 31 31 mm 278273SDO Steel/Yellow Gold Silver

The Rolex Lady-Datejust 31 is one of the most storied and recognizable watches in horological history, tracing its lineage back to the original Datejust introduced in 1945—the first self-winding wristwatch to display the date in a window at three o'clock. Over the decades the Lady-Datejust has evolved into the definitive expression of refined feminine watchmaking, balancing technical excellence with enduring aesthetic elegance. Reference 278273SDO continues that tradition, bringing the collection into the modern era with a 31mm case that sits beautifully on a wide range of wrist sizes.

The case of the 278273SDO is constructed in a two-tone combination of Oystersteel and 18k yellow gold, a pairing Rolex has mastered over generations. Oystersteel, Rolex's proprietary alloy from the 904L steel family, offers exceptional corrosion resistance and a brilliant polish that retains its luster under daily wear. The addition of 18k yellow gold on the bezel and select bracelet links introduces warmth and luxury, creating a watch that transitions effortlessly from a business setting to an evening occasion.

The silver dial is an exercise in understated refinement. Clean and luminous, it provides immediate legibility while lending the watch a light, airy character that pairs naturally with the warm tones of the yellow gold fluted bezel. The fluted bezel itself is one of Rolex's most iconic design signatures, its precise geometric grooves originally conceived as a functional screwback tool and now an enduring symbol of the brand's design language. Together, dial and bezel create a face that is instantly identifiable as a Rolex.

Beneath the Oyster case, an automatic movement drives the watch with the reliability and precision that Rolex is universally recognized for. The Oyster bracelet completes the package, its three-piece link construction offering a secure, comfortable fit and a polished-and-satin finishing that mirrors the two-tone aesthetic of the case. The watch is rated to 100 meters (330 feet) of water resistance, underscoring the robust Oyster architecture that protects the movement from dust, pressure, and moisture in everyday life.
