Rolex Lady-Datejust 31 31 mm 278241WMDO Steel/Rose Gold White Mother of Pearl

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced in 1957 as the first self-winding waterproof watch created specifically for women. Over six decades later it remains the definitive dress-sport watch for women, admired for its balanced proportions, impeccable finishing, and the unmistakable date window at three o'clock that gives the collection its name. Reference 278241WMDO represents a thoroughly modern interpretation of that heritage, bringing together two of the most desirable materials in Rolex's catalogue—Oystersteel and 18k Everose Gold—in a 31mm case sized to sit gracefully on a wide range of wrists.

The case itself measures 31mm in diameter, a dimension Rolex has refined over many generations to achieve the ideal balance between visual impact and wearing comfort. Oystersteel, Rolex's proprietary 904L stainless steel alloy, forms the case body and Oyster bracelet, lending exceptional corrosion resistance and a brilliant, mirror-like polish that holds its lustre over years of daily wear. The crown and bezel are rendered in 18k Everose Gold, Rolex's exclusive rose-gold alloy formulated to resist fading and maintain its warm pinkish hue indefinitely—a permanence you simply cannot count on from standard rose gold.

The smooth domed bezel in 18k Everose Gold is one of the defining aesthetic choices of this reference. Its clean, unadorned arc draws the eye downward to the dial, where the real drama unfolds. The white mother of pearl dial is a naturally occurring gemstone material harvested from mollusk shells; each dial is unique, its surface shifting between cream, silver, and faint iridescent color depending on the angle of light. No two examples are identical, meaning the watch you wear is genuinely one of a kind. Hour markers and hands in matching rose gold complete the composition with understated luxury.

Power comes from a Rolex-certified automatic movement, a self-winding mechanical caliber that keeps the watch running through the natural motion of the wearer's wrist. The movement delivers the date complication that is synonymous with the Datejust name, displayed through the magnifying Cyclops lens Rolex pioneered. Water resistance is rated to 100 metres (330 feet), achieved through the screw-down Twinlock crown and the hermetically sealed Oyster case—a specification that far exceeds what most wearers will ever demand of a dress watch, and a reassuring measure of everyday robustness.

The three-link Oyster bracelet in Oystersteel with rose gold centre links completes the two-tone aesthetic and provides the secure, adjustable fit that Rolex bracelets are celebrated for worldwide. Whether worn to a formal occasion or through the routines of daily life, the Lady-Datejust 31 ref. 278241WMDO offers a level of versatility that few watches at any price can match. Its 31mm footprint reads as refined rather than understated, and the interplay of steel, rose gold, and mother of pearl gives it a presence that reads clearly from across a room.
