Rolex Lady-Datejust 31 31 mm 278288RBRDGRDVIP Yellow Gold/Diamonds Grey

The Rolex Lady-Datejust 31 is one of the most enduring icons in fine watchmaking—a timepiece that has graced the wrists of distinguished women since Rolex introduced the Datejust line in 1945, making it the first self-winding waterproof chronometer wristwatch to display the date. The 31mm mid-size case sits at the sweet spot of the Lady-Datejust family, offering a slightly more assertive presence than the classic 28mm while remaining elegantly proportioned. Reference 278288RBR represents the apex of this storied model, rendered entirely in 18k yellow gold and elevated by a factory diamond-set bezel that announces itself with quiet confidence.

The dark grey Roman dial of this reference is a masterclass in contrast and legibility. Against the warm luminosity of the yellow gold case and bracelet, the cool grey surface creates a sophisticated chromatic tension that reads as both contemporary and timeless. Roman numeral hour markers bring a classical gravitas to the dial, nodding to centuries of horological tradition while remaining unmistakably Rolex in their precision and refinement. Every detail—from the sweep of the hands to the cyclops lens magnifying the date window at three o'clock—is executed to the exacting standards that define the Rolex manufacture.

Powering the Lady-Datejust 31 is Rolex's in-house automatic movement, a self-winding caliber that reflects decades of continuous development and rigorous testing at the Rolex manufacture in Geneva. Rolex movements are certified Swiss chronometers, meaning they have passed the stringent accuracy standards set by the Contrôle Officiel Suisse des Chronomètres (COSC) and further regulated by Rolex's own internal standards. The result is a movement that delivers reliability and precision day after day without the need for manual winding.

The President bracelet—available exclusively on Day-Date and Lady-Datejust models—is one of the most recognizable and coveted bracelets in the watch world. Introduced in 1956 and named in honor of President Dwight D. Eisenhower, it features semi-circular three-piece links that create a fluid, almost organic drape around the wrist. In 18k yellow gold, the President bracelet transforms the watch into a piece of jewelry as much as an instrument of timekeeping. The concealed Crownclasp ensures a seamless aesthetic on the outside of the wrist while providing a secure and comfortable fit.

For collectors and first-time luxury watch buyers alike, the Rolex Lady-Datejust 31 ref. 278288RBR represents an exceptional acquisition. Yellow gold Rolex references with diamond bezels and President bracelets occupy a tier of desirability that has historically supported strong value retention.
