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

The Rolex Lady-Datejust is one of the most enduring and recognizable luxury watches in horological history. Introduced as a smaller-cased evolution of the legendary Datejust family, the Lady-Datejust has long served as Rolex's definitive statement in refined feminine watchmaking. The 31mm case size strikes a balance between the classic 28mm Lady-Datejust and the full-size 36mm Datejust, offering a contemporary wrist presence that reads equally well dressed up or dressed down. Reference 278341RBRRDO represents the line at its most glamorous, combining two noble materials and brilliant-cut diamonds in a single cohesive design.

The 31mm Oyster case of ref. 278341RBRRDO is crafted in Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish — and paired with 18k Everose gold components. Everose gold is Rolex's exclusive rose-gold alloy, formulated to resist fading and maintain its warm blush tone across decades of wear. The combination gives the watch a two-tone character that has been a Datejust hallmark since the 1940s, here elevated by the addition of diamond accents throughout the case architecture.

The rose dial is the visual centerpiece of this reference. Rolex produces its dials in-house, and the rose-hued sunray finish interacts with ambient light to create a sense of depth and warmth that complements the Everose gold perfectly. The dial's clean layout is consistent with Datejust tradition: applied hour markers, refined hands, and the iconic date window at 3 o'clock framed by Rolex's signature Cyclops lens for easy legibility — all hallmarks that make the Datejust immediately identifiable across generations.

The domed bezel set with diamonds is what elevates ref. 278341RBRRDO into genuine jewellery-watch territory. Rolex's gem-setting artisans individually select and hand-set each brilliant-cut diamond for uniformity of color and brilliance before they are secured in the 18k Everose gold bezel. The result is a scintillating frame around the dial that adds drama without overpowering the watch's essential legibility. Completed by the robust three-link Oyster bracelet in matching Oystersteel and Everose gold, the watch is as comfortable and secure on the wrist as any sports Rolex, while looking unmistakably dressed.

At the heart of this Lady-Datejust beats a self-winding automatic movement, ensuring reliable, battery-free timekeeping entirely consistent with Rolex's manufacturing standards. The Oyster case provides water resistance to 100 meters (330 feet), making this not merely a showpiece but a watch capable of accompanying its owner through everyday life with total confidence. From a morning meeting to an evening event, the 278341RBRRDO transitions effortlessly.
