Rolex Lady-Datejust 31 31 mm 278381RBRCDO Steel/Rose Gold/Diamonds Chocolate

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced as the first self-winding waterproof wristwatch with an automatically changing date to be designed specifically for women. Over decades the collection has evolved in refinement and material sophistication while retaining the instantly recognizable Datejust silhouette—the fluted or jeweled bezel, the cyclops lens over the date, and the jubilant Oyster case that has defined Rolex's identity since the mid-twentieth century. The 31mm case size occupies a confident middle ground, generous enough to command attention yet scaled with elegance for the wrist.

Reference 278381RBRCDO brings together two of Rolex's most celebrated materials: Oystersteel, the brand's proprietary 904L stainless steel prized for its exceptional corrosion resistance and mirror-polish quality, and 18k Everose gold, Rolex's exclusive rose-gold alloy formulated to resist fading over time. The interplay of cool steel and warm rose gold across the case, crown, and Oyster bracelet creates a two-tone harmony that has been coveted by collectors for generations, here elevated further by the diamond-set bezel that frames the watch in continuous brilliant-cut sparkle.

The chocolate dial of the 278381RBRCDO is one of its most compelling features. Rich, deep, and unmistakably warm, the chocolate tone creates a striking contrast against the rose gold indices and hands while harmonizing beautifully with the Everose gold elements of the case. Diamond hour markers set into the dial add another dimension of brilliance, ensuring the watch captures light from every angle and reads as a true jewelry-watch hybrid rather than simply a dress timepiece.

Beneath the Oyster case, a Rolex automatic movement drives the watch with the precision and reliability that the brand's owners worldwide have come to expect. The Oyster case itself provides 100 meters (330 feet) of water resistance, sealed by a screw-down Triplock crown, making this Lady-Datejust genuinely versatile—equally at home at a formal dinner, a weekend brunch, or an afternoon at the pool. The Oyster bracelet, with its three flat links, integrates seamlessly with the case and offers robust comfort and security on the wrist.
