Rolex Lady-Datejust 31 31 mm 278243OGDO Steel/Yellow Gold Green

The Rolex Lady-Datejust is one of the most storied women's watch families in horological history, a lineage that traces its roots to 1957 when Rolex introduced the first Lady-Datejust as the world's first self-winding waterproof watch with a date display scaled expressly for a woman's wrist. Across decades the model has remained the definitive benchmark of elegant, purposeful Swiss watchmaking for women — refined enough for a formal occasion, robust enough for daily life. The 31mm case size occupies the sweet spot of the current Lady-Datejust collection, offering a presence that reads clearly on the wrist without ever overpowering a refined silhouette.

Reference 278243OGDO is finished in Oystersteel — Rolex's proprietary 904L stainless steel prized for its exceptional corrosion resistance and mirror-bright polish — blended with 18k yellow gold on the bezel and bracelet centre links. This two-tone architecture, sometimes called Rolesor in Rolex nomenclature, has been a cornerstone of the Datejust aesthetic for generations: the interplay of cool steel and warm gold gives the watch a versatility that a fully precious-metal watch cannot match, transitioning effortlessly from boardroom to weekend.

The crown jewel of this reference is its green dial. Deep, saturated greens have become among the most coveted dial colours in contemporary watchmaking, and on the Lady-Datejust the shade brings a sense of organic richness that pairs beautifully with the warm tones of the yellow gold domed bezel. The domed profile of that bezel is a classical Datejust silhouette, echoing the earliest references of the model and lending the watch a graceful, feminine arc that catches light from every angle.

Beneath the Oyster case the watch is driven by an automatic movement, providing the self-winding convenience that Rolex has championed since the invention of the Perpetual rotor. The Oyster case itself is a feat of engineering: its monobloc middle case, screwed-down caseback, and Twinlock crown combine to achieve 100 meters (330 feet) of water resistance, making this Lady-Datejust genuinely resistant to swimming and everyday splashes — not merely a desk diver but a true Oyster in every sense. The Oyster bracelet completes the package, its three-link construction offering a supple, secure fit with the legendary durability that Rolex bracelets are known for.
