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

Reference 279163 in Yellow Rolesor — the combination of Oystersteel with 18-carat yellow gold — brings the Lady-Datejust 28 into territory that balances everyday wearability with genuine precious-metal warmth. Yellow Rolesor is among the oldest configurations in the Datejust lineage, the original two-tone specification that Rolex introduced in the 1940s, and it remains the most immediately recognisable. In the 279163, the yellow gold elements appear at the bezel, crown, and Oyster bracelet centre links, creating a harmonious interplay with the steel's cooler flanks.

The champagne diamond dial presents hour markers as individually set brilliant-cut diamonds against a warm champagne — or golden-beige — ground. The dial's surface colour is achieved through controlled lacquer application and in some configurations through gold powder saturation, creating the impression of a warm, luminous field that complements the yellow Rolesor aesthetic precisely. The domed bezel of this reference, in yellow gold, differs from gem-set variants and maintains a cleaner architectural line around the dial.

Inside runs Calibre 2236, the movement Rolex introduced specifically for the 28 mm Lady-Datejust. Its centrepiece is the Syloxi hairspring — a silicon component produced using LIGA microfabrication techniques, delivering thermal stability and magnetic immunity superior to conventional Nivarox alloys. At 55 hours of power reserve, it exceeds the previous generation Calibre 2235 by a meaningful margin. The Oyster bracelet with Easylink extension provides a practical convenience Rolex introduced across the Datejust family for all-day comfort, making the 279163 as suited to daily wear as to special occasions.
