Rolex Lady-Datejust 31 31 mm 278245RSDP Rose Gold Rose

The Rolex Lady-Datejust has held a singular place in horological history since Rolex introduced the Datejust family as the world's first self-winding waterproof wristwatch to display the date in a magnified window on the dial. The Lady-Datejust brought those same hallmarks of precision and elegance to a smaller, feminine case, and the modern 31mm sizing of the 278245RSDP sits at the ideal crossover point—substantial enough to read with authority on the wrist yet perfectly proportioned for smaller wrists. Decades of refinement have made the Lady-Datejust one of the most recognized luxury watch silhouettes on earth.

Reference 278245RSDP is executed entirely in Rolex's proprietary 18k Everose gold, the brand's exclusive rose gold alloy developed in-house for exceptional resistance to fading and discoloration over time. The 31mm Oyster case carries that warm, burnished tone from lug to lug, and the smooth domed bezel—free of diamonds or fluting—keeps the design clean and quietly confident. Water resistance to 100 meters (330 feet) is provided by the screw-down Twinlock crown and the hermetically sealed Oyster case construction.

The rose dial of the 278245RSDP deepens the watch's monochromatic composition into something genuinely striking. Set against the warm gold of the case and bezel, the rose-toned dial creates a seamless, almost jewel-like effect that photographs beautifully and reads with equal elegance under natural daylight or evening candlelight. Hour indexes anchor the dial in classic Datejust fashion, and the Cyclops lens over the date aperture at three o'clock delivers the signature 2.5× magnification that has defined the Datejust since its earliest generations.

Power comes from a Rolex automatic movement, delivering the reliable self-winding performance the brand is celebrated for worldwide. Rolex movements in this family are chronometer-certified to COSC standards and benefit from the brand's Superlative Chronometer designation, reflecting precision testing performed in-house after casing. The result is a watch that requires no manual winding in regular daily wear and maintains accuracy that far exceeds industry benchmarks for its class.

The President bracelet—formally known as the Jubilee-successor reserved for Rolex's prestige models—completes the 278245RSDP with three semi-circular links that drape smoothly around the wrist. Rendered entirely in 18k Everose gold, the bracelet is fitted with a concealed folding Crownclasp for a clean profile and secure closure. The combination of case, dial, bezel, and bracelet in a single warm-rose palette gives this reference a dressed cohesion rarely achieved in watchmaking.
