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

The Rolex Lady-Datejust is one of the most enduring and celebrated watches in horological history, introduced by Rolex in 1957 as the first self-winding, waterproof, and date-displaying wristwatch sized specifically for women. Across more than six decades, it has remained the definitive benchmark for feminine luxury watchmaking, worn by icons of culture, sport, and style the world over. The current 31mm generation refines proportions, materials, and aesthetics to suit the contemporary wrist while honoring every tradition that made the model legendary.

Reference 278243OGDJ pairs Oystersteel — Rolex's proprietary 904L stainless steel alloy, prized for its exceptional corrosion resistance and mirror-bright polish — with 18k yellow gold on the bezel and Jubilee bracelet center links. This two-tone combination, often called Rolesor in Rolex nomenclature, strikes a balance between understated durability and unambiguous luxury. The yellow gold domed bezel adds a refined arc of warmth that frames the dial beautifully without overwhelming the 31mm case diameter.

The green dial is the centerpiece of this reference and one of its most compelling attributes. Green has become a signature statement color across the Rolex collection, evoking prestige, vitality, and a certain sartorial confidence. On the Lady-Datejust 31, the rich green hue is rendered with the depth and finish that only Rolex's in-house dial manufacturing can achieve, complementing the yellow gold indices and hands for a cohesive, luminous presentation.

Powering the watch is a Rolex-certified automatic movement, guaranteeing the precision and reliability that the Superlative Chronometer designation demands. Rolex movements are assembled, regulated, and tested entirely in-house, and the automatic winding rotor ensures effortless daily timekeeping. The case carries a water resistance of 100 meters (330 feet) — a practical advantage that allows this elegant watch to accompany its owner through the full range of daily activities without compromise.

The five-piece Jubilee bracelet, originally designed alongside the Datejust in 1945, is widely regarded as one of the most comfortable and refined metal bracelets ever crafted. Its characteristic small, rounded links drape elegantly against the wrist and echo the warmth of the yellow gold accents throughout the watch. Every surface transition — from brushed center links to polished outer links — speaks to the obsessive craft Rolex brings to every component.
