Rolex Lady-Datejust 31 31 mm 278343RBROGDJ Steel/Yellow Gold/Diamonds Green

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking, having introduced the world to the self-winding wristwatch with a date display in a slender, feminine case size. Launched in 1957 as a companion to the original Datejust introduced a decade earlier, the Lady-Datejust has evolved continuously while preserving the architectural proportions and finishing standards that define the family. The 31mm case size sits between the classic 28mm and the full 36mm, offering a versatile fit that reads equally well on a wide range of wrist sizes and suits both everyday elegance and dressed-up occasions.

Reference 278343RBROGDJ represents the current generation of the Lady-Datejust 31 and showcases one of the most compelling dial and bezel combinations in the lineup. The 31mm case is crafted in Rolex's proprietary Oystersteel — a highly corrosion-resistant 904L stainless steel — contrasted with 18k yellow gold on the bezel, crown, and bracelet center links, producing the classic two-tone aesthetic known in Rolex parlance as the Rolesor configuration. The result is a case that feels simultaneously sporty and luxurious, catching light from every angle.

The olive green dial is the undisputed focal point of this reference. Rich, deep, and slightly warm in tone, the olive green surface offers a sophisticated alternative to the neutral dials that dominated the Datejust family for generations. Paired with the yellow gold domed bezel set with brilliant-cut diamonds, the dial color creates a jewel-like depth that is impossible to replicate in photographs. Hour markers and hands in yellow gold complete the harmonious warm-cool balance across the dial.

The yellow gold domed bezel is set with a single row of brilliant-cut diamonds, adding a layer of haute joaillerie to what is already an exceptional watch. Rolex sets these diamonds in-house to exacting standards, selecting stones for color, cut, and brilliance consistency. The domed profile of the bezel is a design cue borrowed from early Datejust references, giving the case a softer, more sculptural silhouette than the flat bezels found on sportier Rolex models. Completing the package is the five-piece-link Jubilee bracelet in Oystersteel and yellow gold — one of Rolex's most celebrated bracelets, renowned for its suppleness and comfort on the wrist.

Powered by a Rolex automatic movement, reference 278343RBROGDJ delivers the reliable, self-winding precision that has made Rolex synonymous with accuracy. The Oyster case provides water resistance to 100 meters (330 feet), protecting the movement in conditions well beyond what a dress watch encounter demands. This speaks to the dual nature of the Lady-Datejust: it is beautiful enough for a black-tie evening yet robust enough to accompany an active lifestyle without hesitation.
