Rolex Lady-Datejust 31 31 mm 278341RBRROSJ Steel/Rose Gold/Diamonds Rose

The Rolex Lady-Datejust 31 is one of the most enduring icons in fine watchmaking — a model that has graced the wrists of discerning women since Rolex pioneered the self-winding wristwatch with a date display. Reference 278341RBRROSJ represents a pinnacle expression of that heritage, combining the reliability of the calibrated Datejust platform with materials and finishing that belong unmistakably in the realm of luxury jewelry.

At 31 mm, the case occupies the sweet spot of the Lady-Datejust family: substantial enough to read with clarity throughout the day, yet elegant enough for a formal dinner or a refined weekend occasion. The case itself pairs Oystersteel — Rolex's proprietary 904L stainless steel prized for its corrosion resistance and mirror-bright polish — with 18k Everose gold, Rolex's exclusive rose-gold alloy formulated to maintain its warm blush color without fading over time. The result is a two-tone aesthetic that feels both contemporary and classically Rolex.

The rose dial is the quiet centerpiece of this reference. Presented in a warm, dusty-rose hue, it catches light differently as the day moves from morning to evening, lending the watch an almost chameleon-like quality on the wrist. Surrounding the dial is a domed bezel set with diamonds in 18k Everose gold — an addition that elevates the piece from a precision instrument to a true statement of feminine elegance, scattering light with every movement of the wrist. Hour markers on the dial complement this diamond story, ensuring visual cohesion throughout the design.

The Jubilee bracelet — one of Rolex's most celebrated bracelets, introduced alongside the original Datejust in 1945 — completes the look with its five-piece link construction that drapes softly and securely around the wrist. In the Oystersteel and Everose gold execution found on ref. 278341RBRROSJ, the bracelet picks up the two-tone theme of the case and creates a seamless, unified profile. It is secured by Rolex's Crownclasp, which blends invisibly with the bracelet for a clean, uninterrupted flow. Water resistance is rated to 100 meters, making this watch a practical daily companion as well as a luxurious one.

Powered by an automatic movement, the Lady-Datejust 31 winds itself through the motion of the wearer's wrist, requiring no battery and demanding minimal intervention. The movement reflects Rolex's philosophy that true luxury must also be supremely functional — a watch this beautiful should also tell precise, reliable time day after day. Rolex manufactures its movements in-house to the highest standards of chronometric precision, and the Lady-Datejust family benefits fully from that commitment.
