Rolex Datejust 28 Yellow Rolesor — Champagne Diamond Dial | Ref. 279163

Reference 279163 is a Lady-Datejust 28 in Yellow Rolesor — Oystersteel combined with 18ct yellow gold — presenting a champagne dial set with diamond hour markers. The 279xxx reference block places this firmly in the current generation of Lady-Datejust production, introduced in 2016 alongside the Calibre 2236. At 28mm, this is Rolex's current dedicated women's Datejust case size, replacing the earlier 26mm format with a diameter that offers marginally improved legibility while maintaining the proportional elegance appropriate to the model's positioning. The champagne dial colour resonates naturally with yellow gold accents, the two warm tones creating a harmonious chromatic relationship that white or steel dials against yellow gold cannot replicate.

The Calibre 2236 is the defining technical feature of this generation. Rolex developed the 2236 to bring the advantages of the Syloxi silicon hairspring — superior antimagnetic performance, thermal stability, and insensitivity to lubricant degradation — to its smaller-cased models. The movement runs at 28,800 vph and provides a 55-hour power reserve, a substantial improvement over the Calibre 2235 it replaced. The 18ct yellow gold bezel (smooth or fluted depending on specific variant) and crown guards contrast against the steel case body, and the Jubilee bracelet in Oystersteel with yellow gold centre links provides the characteristic five-piece link wearing experience.

The 279163 occupies a sweet spot in the Lady-Datejust range: more accessible than a full yellow gold or diamond bezel variant, yet more distinguished than an all-steel configuration. Diamond hour markers on a champagne dial represent the most popular dial option within the yellow Rolesor 28mm range, which means secondary market availability is relatively consistent and pricing is well-established. Buyers seeking a current-generation women's Rolex that functions as both a precision timepiece and an everyday luxury accessory will find this reference squarely aligned with that brief.
