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

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, tracing its lineage to 1957 when Rolex introduced a scaled version of the original Datejust for women. Across more than six decades the model has remained the definitive expression of understated luxury on a feminine wrist, combining the legendary reliability of the Oyster case with dial designs that range from restrained elegance to full haute-joaillerie splendor. Reference 278341RBR sits squarely at the glamorous end of that spectrum, bringing together precious metal, diamonds, and a deeply romantic color palette.

The 31 mm Oyster case of the Lady-Datejust 278341RBR is constructed from a combination of Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish — and 18k Everose gold, Rolex's exclusive rose-gold alloy engineered to resist fading over time. This two-tone architecture, sometimes called Rolesor in Rolex nomenclature, allows the warmth of rose gold to accentuate the lugs, crown, and bezel while keeping the overall watch accessible in weight and proportion for everyday wear.

The bezel is one of the most eye-catching elements of reference 278341RBR: a domed profile set with diamonds in 18k Everose gold that frames the dial with continuous sparkle. Beneath it lies a rose Roman numeral dial whose blush color and classical hour markers create an unmistakably romantic aesthetic. The combination of the diamond bezel and the Roman numerals gives the watch a sense of occasion without sacrificing legibility, a balance Rolex's designers have refined over generations.

Powering the Lady-Datejust 31 is a certified Swiss automatic movement, allowing the watch to be worn without ever needing to wind a battery. The Oyster case provides 100 meters (330 feet) of water resistance, sealing the movement behind the iconic screw-down Triplock crown and a caseback engineered to keep moisture out — meaning this is a watch you can wear from the pool to the boardroom without hesitation. The Oyster bracelet in matching Oystersteel and Everose gold echoes the case's two-tone palette and fastens with a secure folding Crownclasp for a confident fit.

For collectors and first-time luxury watch buyers alike, the Lady-Datejust 278341RBR represents exceptional long-term value. Rolex's commitment to in-house manufacturing, strict quality standards, and controlled supply has consistently supported strong residual values for diamond-bezel two-tone references.
