Rolex Lady-Datejust Yellow Rolesor — Champagne Index Dial | Ref. 279163 (2)

The Lady-Datejust 28 reference 279163 in Yellow Rolesor is one of the more traditional expressions of the 28mm case — a watch that draws on the long heritage of yellow gold in the Datejust lineage without the cost of a fully solid gold construction. Yellow Rolesor pairs Oystersteel case flanks and caseback with 18k yellow gold on the bezel and crown, producing the bicolour visual that has been a Rolex staple since the Rolesor concept was formalised in the 1930s. The champagne index dial ties the palette together, its warm hue echoing the yellow gold elements throughout.

Driving the 28mm Oyster case is the Calibre 2236, the current in-house movement for this case size. The Syloxi hairspring — manufactured from a silicon-based alloy developed by Rolex — provides resistance to magnetic fields and temperature variation beyond what conventional Nivarox hairsprings can offer. A 55-hour power reserve serves the Lady-Datejust's role as an everyday watch, ensuring reliable timekeeping across a standard weekend without winding. The Jubilee bracelet in matching Rolesor steel and yellow gold carries the five-piece link construction that has defined the Datejust bracelet since 1945.

For the prospective buyer, the 279163 in Yellow Rolesor occupies a sweet spot: accessible compared to fully solid gold references, yet visually distinct from all-steel configurations. Champagne index dials maintain consistent demand in the secondary market because of their broad wearability and tonal versatility — complementing both warm and neutral wardrobes equally well. Pre-owned examples from the current 279xxx generation benefit from the updated calibre and any remaining transferable warranty from the original purchase date.
