Rolex Lady-Datejust 31 31 mm 278241RRO Steel/Rose Gold Rose

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, having introduced the world's first self-winding waterproof wristwatch with a date function sized for a woman's wrist when it debuted in 1957. Across more than six decades the line has evolved in materials, dial treatments, and bracelet options while retaining the instantly recognizable Datejust silhouette that made it famous. Reference 278241RRO represents the modern expression of this legacy, sitting at the contemporary 31 mm sweet spot that flatters a wide range of wrist sizes without sacrificing presence.

The case of the 278241RRO is crafted from Rolex's proprietary Oystersteel—a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish—paired with 18k Everose gold, Rolex's exclusive rose-gold alloy formulated to resist fading over time. This two-tone combination, sometimes called Rolesor, gives the watch a warm, luxurious character that a steel-only piece cannot replicate while remaining more accessible than a fully precious-metal reference. The smooth domed bezel in 18k Everose gold adds an uncluttered, classic profile that keeps the eye focused on the dial.

The rose dial with Roman numeral hour markers is the defining design choice of this reference and the detail that most drives buyer demand. The soft blush tone works harmoniously with the Everose gold bezel and bracelet center links, creating a cohesive, jewelry-like aesthetic without overwhelming the legibility that Rolex engineering demands. Roman numerals lend a formal, traditional elegance that sets this variant apart from index or diamond-set alternatives in the 278241 family.

Power comes from a Rolex automatic movement housed within the Oyster case, which is water-resistant to 100 meters (330 feet) thanks to the screw-down Triplock winding crown—a level of protection far exceeding the demands of daily wear, light swimming, or unexpected splashes. The Oyster bracelet, with its three-piece link construction and Rolex folding Oysterclasp, provides a secure, comfortable fit that resists stretching and maintains its proportions over years of wear. Together, case and bracelet form a unified, tool-proof package that belies the watch's delicate appearance.

On the wrist, the 31 mm diameter occupies a versatile middle ground: substantial enough to read confidently as a statement piece, yet refined enough to layer alongside fine jewelry or slip under a tailored cuff. The two-tone Rolesor finish means it pairs naturally with both yellow and white metal jewelry, expanding its styling versatility further. Few watches at this size command the same immediate recognition or hold their value as consistently as a Lady-Datejust.
