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

The Rolex Lady-Datejust has held a singular place in horological history since Rolex introduced the Datejust line in 1945 — the world's first self-winding wristwatch to display the date in a window at 3 o'clock. The Lady-Datejust refined that legacy for a smaller wrist, and the 31mm case size of reference 278271ROSJ sits at the sweet spot between the classic 28mm and the full-size 36mm, offering a versatile mid-size silhouette that reads as genuinely contemporary without sacrificing any of the model's storied heritage. Today the Lady-Datejust 31 is one of Rolex's most enduring and recognized references worldwide, worn by collectors who appreciate understated luxury.

Reference 278271ROSJ is built from two of Rolex's signature materials: Oystersteel — the brand's proprietary 904L stainless steel, prized for its exceptional corrosion resistance and mirror-bright polish — and 18k Everose gold, Rolex's own rose-gold alloy formulated to resist fading over decades of wear. The two-tone combination is expressed most visibly on the fluted bezel, crafted entirely in 18k Everose gold, which catches the light with its precisely machined grooves and frames the dial with a warm, luminous rim. The interplay of cool steel and warm gold gives the watch a sophisticated dual-tone character that has remained fashionable across generations.

The rose dial is the visual centerpiece of the 278271ROSJ. Its warm blush hue creates an immediate sense of elegance and femininity, offering a color that is distinctive yet versatile enough to complement both casual and formal attire. Index hour markers — a hallmark of the Datejust aesthetic — are set into the dial, and the date aperture at 3 o'clock is framed by a Cyclops lens on the sapphire crystal for effortless legibility. The overall effect is a dial that feels luxurious without being ostentatious, a quality that defines the Lady-Datejust at its best.

The watch rides on Rolex's iconic Jubilee bracelet, a five-piece-link design first introduced alongside the original Datejust in 1945. The Jubilee is widely regarded as one of the most comfortable and elegant bracelets Rolex produces, its articulated links conforming naturally to the wrist for a supple, secure fit. On the 278271ROSJ the bracelet is rendered in matching Oystersteel and Everose gold, carrying the two-tone motif from case to clasp and ensuring a cohesive, polished appearance from every angle. The Oysterclasp with its Crownclasp system provides a secure and discreet closure.

An automatic movement powers the 278271ROSJ, offering the self-winding convenience and precision that Rolex movements are globally renowned for. The watch carries a water resistance rating of 100 meters (330 feet), underscoring the practicality of the Oyster case construction and making it a true everyday companion rather than merely a display piece. Whether worn to the office, a formal dinner, or weekend leisure, the Lady-Datejust 31 in this reference is engineered to perform reliably in the full spectrum of daily life.
