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

The Rolex Lady-Datejust 31 is one of the most enduring icons in watchmaking — a timepiece that has defined elegance on the wrist since the Datejust family first introduced the date-display complication in 1945. Reference 278241ROSJ represents the modern interpretation of this legacy: a 31mm case that sits with exceptional refinement on the wrist, sized perfectly for those who prefer a mid-size presence without sacrificing the bold identity of the Datejust line. This is a watch that bridges generations, equally at home at a formal dinner or a casual weekend afternoon.

The case of the 278241ROSJ is constructed from a combination of Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its superior corrosion resistance and mirror-bright polish — and 18k Everose gold, Rolex's exclusive rose gold alloy formulated to resist fading over time. This two-tone configuration, sometimes referred to in the collector community as a "Rolesor" combination, gives the watch its warm, luxurious character while grounding it with the practicality of steel. The result is a timepiece that feels both precious and wearable.

At the heart of the dial experience is the rose-toned face, which harmonizes beautifully with the Everose gold accents throughout the watch. The smooth domed bezel in rose gold frames the dial with quiet confidence, forgoing gem-setting in favor of clean, architectural lines that allow the dial's warmth to take center stage. This restraint is characteristic of the best Datejust references — a design philosophy that trusts the quality of materials to speak for themselves rather than relying on ornament.

The Jubilee bracelet — one of the most recognizable and celebrated bracelets in horological history — completes the look. Introduced alongside the original Datejust in 1945, the five-piece link Jubilee construction delivers a supple, fluid drape on the wrist that is instantly recognizable. In the two-tone Oystersteel and Everose gold configuration of the 278241ROSJ, the bracelet ties together the case and dial into a cohesive, polished whole. The watch is water resistant to 100 meters (330 feet), courtesy of the Oyster case's screw-down crown, making it genuinely suitable for everyday wear.

The Lady-Datejust 31 ref. 278241ROSJ is powered by an automatic movement, reflecting Rolex's commitment to self-winding mechanical excellence that has defined the brand for decades. A Rolex automatic caliber winds itself continuously through the motion of the wearer's wrist via the Perpetual rotor, ensuring the watch is always ready when you reach for it. This mechanical heart, combined with Rolex's legendary manufacturing standards, means the 278241ROSJ is built to perform reliably for a lifetime.
