Rolex Lady-Datejust 31 31 mm 278271SDO Steel/Rose Gold Silver

The Rolex Lady-Datejust 31 is one of the most enduring icons in Swiss watchmaking, and reference 278271SDO represents the line at its most sophisticated. Introduced as the world's first self-winding waterproof wristwatch with a date display, the Datejust has been a cornerstone of the Rolex catalogue since 1945. The Lady-Datejust 31 occupies the sweet spot in the collection, offering a case diameter of 31mm that sits elegantly on a wide range of wrist sizes while retaining the full visual vocabulary of the Datejust design language.

The case of the 278271SDO is constructed in a combination of Oystersteel—Rolex's proprietary 904L stainless steel prized for its exceptional corrosion resistance and mirror-like polish—and 18k Everose Gold, the house's exclusive rose gold alloy formulated to maintain its warm blush hue over decades of wear. This two-tone configuration, often called Rolesor by the manufacture, has been a signature of the Datejust line for generations and signals effortless versatility: dressed up for an evening occasion or worn daily without a second thought.

The silver dial of this reference is a study in restrained luxury. Clean and luminous, a silver dial pairs naturally with both the cool brilliance of steel and the warm glow of rose gold, creating a dial face that reads crisply at a glance while exuding understated refinement. The iconic date aperture at three o'clock, framed by the characteristic Cyclops lens on the crystal, provides immediate legibility that has defined the Datejust since its inception.

Crowing the case is the fluted bezel rendered entirely in 18k Everose Gold, the detail that most clearly announces this watch's two-tone identity from across a room. The fluted bezel is not merely decorative; originally engineered to screw the bezel onto the case and reinforce waterproofness, it has become one of watchmaking's most recognizable motifs. Securing the case to the wrist is the three-link Oyster bracelet, arguably the world's most recognized watch bracelet, combining flat three-piece links for a structured, confident fit. Water resistance is rated to 100 meters, underscoring the Oyster case's robust hermetic sealing.

At its heart the Lady-Datejust 31 ref. 278271SDO is driven by a Rolex automatic movement, self-winding through the wearer's natural motion and engineered to the exacting tolerances that have earned Rolex its reputation for reliability. The movement is housed in the screw-down Oyster case, protecting it from dust, pressure, and moisture in daily life.
