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

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, having defined the standard for elegant women's timepieces since its introduction. The 31 mm case size sits at the heart of the Lady-Datejust lineup, offering a versatile and wrist-flattering proportion that suits a wide range of wearers. Reference 278341RBRRSJ represents one of the most luxurious expressions of this storied model, combining Oystersteel and 18k Everose gold with diamond embellishment for a watch that is simultaneously classic and genuinely glamorous.

The case of the 278341RBRRSJ measures 31 mm and is constructed from Rolex's proprietary Oystersteel — a high-performance 904L stainless steel alloy celebrated for its exceptional corrosion resistance and brilliant polish — paired with 18k Everose gold, Rolex's exclusive rose gold alloy engineered to maintain its warm, rosy hue over a lifetime of wear. The case architecture follows Rolex's Oyster design philosophy: robust, elegantly proportioned, and built to the highest standards of Swiss precision manufacturing.

At the center of the dial sits a slate-toned surface, a deeply modern and sophisticated color choice that reads as a near-neutral in many lighting conditions yet reveals rich depth and complexity in direct light. Slate pairs exceptionally well with the warmth of Everose gold and the brilliance of the diamond-set domed bezel, creating a watch that carries both daytime restraint and evening drama in equal measure. The index hour markers provide clean, legible timekeeping in a style that is unmistakably Rolex.

The domed bezel of the 278341RBRRSJ is set with diamonds in 18k Everose gold, adding a layer of haute joaillerie craftsmanship to what is already a highly engineered timepiece. The Jubilee bracelet — one of the most beloved bracelet designs in watchmaking, introduced by Rolex in 1945 — rounds out the package with its five-piece link construction, delivering a supple, refined drape on the wrist and an unmistakable sense of occasion. The watch is water resistant to 100 meters (330 feet), underscoring the functional integrity of the Oyster case beneath the jeweled exterior.

Powered by an automatic movement, the Lady-Datejust 31 requires no manual winding under normal daily wear and delivers the reliable, accurate timekeeping that has made Rolex synonymous with horological excellence worldwide. The self-winding mechanism keeps the watch running through the natural motion of the wearer's wrist, ensuring it is always ready to perform.
