Rolex Lady-Datejust 31 31 mm 278383RBROGDO Steel/Yellow Gold/Diamonds Green

The Rolex Lady-Datejust 31 ref. 278383RBR is one of the most coveted expressions of a watch lineage that has defined feminine luxury watchmaking for decades. Introduced in 1957 as a scaled counterpart to the original Datejust, the Lady-Datejust has always balanced the iconic design language of the Datejust family with proportions tailored for a broader range of wrists. The 31mm case size sits at a sweet spot between Rolex's 28mm Ladies Datejust and the full 36mm Datejust, making ref. 278383RBR especially versatile and highly sought after on the pre-owned market.

The case and bracelet of the 278383RBR are constructed in Rolex's proprietary Oystersteel — a 904L stainless steel alloy celebrated for its exceptional corrosion resistance and mirror-bright polish — complemented by 18k yellow gold accents on the bezel setting, crown, and Oyster bracelet center links. This two-tone Rolesor construction, a Rolex hallmark, adds warmth and visual depth that pure steel references cannot achieve, and it harmonizes beautifully with the rich olive green dial at the heart of this watch.

The olive green dial is one of the most distinctive and fashionable color choices in the current Lady-Datejust range. Its depth shifts under different lighting conditions, appearing almost forest-toned in shade and luminously warm in sunlight. The diamond-set bezel crowns the dial with a continuous ring of brilliant-cut diamonds, intensifying the interplay of light and color and elevating this reference firmly into jewellery-watch territory without sacrificing the everyday wearability for which Rolex is renowned.

Beneath the Oyster case, an automatic movement keeps precise time with the reliability that Rolex owners expect. The Oyster case itself — sealed by a screw-down Triplock winding crown — provides meaningful water resistance, making the 278383RBR a watch that can be worn confidently in everyday situations. The three-link Oyster bracelet, fitted with Rolex's Oysterclasp, ensures a secure and comfortable fit on the wrist, completing a package that is as practical as it is luxurious.

For collectors and first-time Rolex buyers alike, the Lady-Datejust 31 278383RBR represents exceptional long-term value. Rolex's combination of proprietary materials, in-house movements, and timeless design has historically supported strong resale values, and diamond-bezel two-tone references in desirable dial colors like olive green are perennially popular.
