Rolex Lady-Datejust 31 31 mm 278271ROSO Steel/Rose Gold Rose

The Rolex Lady-Datejust is arguably the most enduring women's luxury watch ever made, tracing its lineage to 1957 when Rolex introduced the first Datejust scaled for a woman's wrist. Over decades it has remained the definitive reference point for elegant, date-displaying mechanical watchmaking, worn by generations of accomplished women worldwide. Reference 278271ROSO represents the current 31mm expression of that heritage, combining the timeless Datejust architecture with the warmth of Rolex's proprietary 18k Everose gold alloy.

At 31mm, the case occupies a versatile middle ground—larger than the original 26mm Lady-Datejust yet refined enough to sit gracefully on a range of wrist sizes. The case is built in Oystersteel, Rolex's proprietary 904L stainless steel alloy renowned for its exceptional corrosion resistance and mirror-polish retention, while the crown, bezel, and bracelet centre links are rendered in 18k Everose gold, a rose-gold formula Rolex developed to resist fading over decades of wear. Together they produce the brand's signature two-tone Rolesor aesthetic in its most romantic expression.

The rose dial is the centrepiece of this reference. Its warm, blush-toned surface creates an immediate visual harmony with the Everose gold fluted bezel, whose faceted grooves catch light from every angle and remain a hallmark of Datejust design dating back to 1945. Index hour markers in matching gold tones and slender dauphine hands ensure legibility without disturbing the dial's soft, unified colour story.

Power comes from Rolex's self-winding automatic movement, a certified Swiss chronometer held to tolerances far tighter than the industry standard, ensuring the date display and timekeeping accuracy that have made the Datejust a trusted daily companion for nearly eight decades. The movement is sealed inside the Oyster case, which provides water resistance to 100 metres (330 feet)—more than sufficient for swimming and everyday exposure to water—secured by the screw-down Triplock winding crown.

The Oyster bracelet on the 278271ROSO is one of the most copied and least equalled bracelet designs in horology. Its three-link construction in alternating Oystersteel and Everose gold is secured by Rolex's Crownadjust extension system concealed within the folding Oysterclasp, allowing a precise half-millimetre fit adjustment without tools. The result is a bracelet that feels as considered as the watch itself.
