Rolex Lady-Datejust 31 31 mm 278285RBRSVFLOMDP Rose Gold/Diamonds Silver Rolex Lady-Datejust 31 31 mm 278285RBRSVFLOMDP Rose…

The Rolex Lady-Datejust is one of the most storied watches in the brand's catalogue, tracing its lineage to 1957 when Rolex introduced a scaled version of the legendary Datejust — itself the world's first self-winding waterproof chronometer wristwatch with an automatic date-changing mechanism, launched in 1945. Over the decades the Lady-Datejust has remained the definitive Rolex dress watch for women, and reference 278285RBRSVFLOMDP represents the line at its most opulent: a 31mm case in 18k Everose gold, Rolex's proprietary rose-gold alloy formulated to resist fading, adorned with a factory diamond-set bezel and paired with the storied President bracelet.

The 31mm case size places this reference at the heart of the current Lady-Datejust collection. Neither too petite nor overpowering, 31mm provides a balanced wrist presence that suits a wide range of wrist sizes while still projecting the quiet authority that a fully gem-set Rolex commands. The case is crafted entirely in 18k Everose gold, Rolex's proprietary alloy developed in-house for its warm, enduring colour, and every surface — from the polished lugs to the brushed centre links of the President bracelet — reflects the brand's exacting finishing standards.

The dial of reference 278285RBRSVFLOMDP is a silver floral motif, a highly decorative treatment in which a delicate botanical pattern is rendered across the silver surface, catching light differently at every angle. This style of dial elevates the watch firmly into jewellery-watch territory, pairing naturally with the diamond-set bezel that frames it. The bezel itself is set with a continuous band of brilliant-cut diamonds in a graduated arrangement, a hallmark of Rolex's in-house gem-setting expertise and a feature that has defined the luxury tier of the Datejust family for generations.

Power comes from Rolex's automatic movement, a self-winding calibre that winds via the motion of the wearer's wrist and keeps the watch running reliably day after day without the need for manual winding. The watch is water resistant to 100 metres (330 feet), a specification that far exceeds what is required of a dress watch and speaks to the robustness built into every Rolex regardless of its aesthetic positioning. The Oyster case construction — including the screw-down Twinlock crown — seals the movement from the elements while the Cyclops lens over the date window at 3 o'clock magnifies the date 2.5 times for effortless legibility.

The President bracelet, originally introduced alongside the Day-Date in 1956 and named in honour of U.S. President Dwight D. Eisenhower, is composed of semi-circular three-piece links that give it a smooth, rounded profile unlike any other Rolex bracelet. Rendered here entirely in 18k Everose gold and fitted with Rolex's concealed Crown Clasp, it adds significant intrinsic value to the watch and contributes to the seamless, jewellery-like appearance that makes this reference so desirable.
