Rolex Lady-Datejust 31 31 mm 278381RBRRDO Steel/Rose Gold/Diamonds Rose

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history — the first waterproof wristwatch to feature a date display on the dial, and the first to be sized expressly for women. Introduced in 1957 as a feminine counterpart to the Datejust, the Lady-Datejust has evolved across decades while retaining its signature elegance, balance, and horological integrity. Reference 278381RBRRDO represents the 31mm generation of this lineage, a size that sits beautifully on the wrist while accommodating all the refinement Rolex builds into every case.

The case of the 278381RBRRDO is constructed in a two-tone combination of Oystersteel — Rolex's proprietary 904L stainless steel, renowned for its exceptional corrosion resistance and mirror-polish depth — and 18k Everose gold, Rolex's exclusive rose gold alloy formulated to resist fading over time. At 31mm in diameter, the Oyster case strikes the ideal balance between presence and delicacy, wearing comfortably on a wide range of wrist sizes without ever feeling oversized or understated.

The rose diamond dial is the visual centerpiece of this reference. Rich in color and texture, the rose dial is elevated by diamond hour markers that catch light from every angle, transforming a precision instrument into a piece of fine jewelry. The diamond-set bezel — a hallmark of Rolex's most glamorous Datejust configurations — encircles the dial with a continuous ring of brilliant-cut diamonds, amplifying the watch's luminosity and its identity as a statement of refined taste.

Powering this Lady-Datejust 31 is a Rolex automatic movement, delivering the reliable self-winding performance and date complication that have defined the Datejust for over six decades. The Oyster bracelet, with its signature three-link design and blend of polished and satin-finished surfaces, integrates seamlessly with the two-tone case and fastens with Rolex's folding Crownclasp for a secure, comfortable fit. The Oyster case construction also provides water resistance to 100 meters (330 feet), meaning this watch is built to accompany an active lifestyle without compromise.

For collectors and first-time luxury watch buyers alike, the Lady-Datejust 31 ref. 278381RBRRDO occupies a uniquely compelling position in the market. It is simultaneously a status symbol, a fine jewelry piece, and a serious mechanical timepiece — versatile enough for daily wear yet polished enough for formal occasions. Demand for diamond-dial, diamond-bezel Datejust references in Everose gold and steel consistently remains strong, making this reference not only a pleasure to wear but a wise addition to any collection.
