Introduced as part of Rolex's 2018 expansion of the Lady-Datejust collection, the reference 279383RBR represents the convergence of classical proportions with contemporary diamond artistry in a perfectly scaled 28mm yellow gold case. This particular configuration pairs the timeless appeal of Roman numeral indices against a silver dial with the sparkling brilliance of a factory diamond-set bezel, creating one of the most sought-after variants within the Lady-Datejust lineup. The Rolesor construction—Rolex's proprietary term for steel and gold combination—elevates this Rolex Datejust 279383RBR beyond mere timekeeping into the realm of jewelry-grade horology, while the five-link Jubilee bracelet provides the sophisticated comfort that has defined the collection since 1945.
