Rolex Lady-Datejust Yellow Rolesor — White Roman Dial | Ref. 279163

The Lady-Datejust 28 in Yellow Rolesor is among the most elegantly resolved pieces in Rolex's current catalogue, combining the warmth of 18k yellow gold with the durability of Oystersteel in a combination that has endured for decades as the definitive two-tone expression. Reference 279163 carries a white dial with Roman numeral hour markers, a pairing that conjures the spirit of classic dress watchmaking within a thoroughly modern, technically advanced case.

At 28mm, the Lady-Datejust 28 is powered by the Calibre 2236, a manufacture movement that represents Rolex's most recent development for this case size. The 2236 incorporates a Syloxi hairspring — a silicon component machined to micron tolerances — which dramatically improves resistance to magnetic fields and temperature variation while delivering COSC-certified chronometric precision. The Rolesor combination sees yellow gold applied to the bezel, crown, and bracelet centre links, while Oystersteel forms the case flanks and outer bracelet links.

Ref. 279163 sits at the heart of Rolex's lady's dress watch offering and enjoys strong collector recognition precisely because it represents the brand's most current movement technology in a historically celebrated format. The Roman numeral dial variant is particularly sought after for its legibility and classical character, making it a natural choice for those who wear their watches as much for personal expression as for timekeeping. Condition and originality of the dial are paramount when evaluating examples on the secondary market.
