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

Reference 279163 brings together Yellow Rolesor construction and a diamond-set silver dial in the current 28mm Lady-Datejust case, producing a configuration that balances Rolex's foundational elegance with deliberate luxury. Yellow Rolesor pairs 18k yellow gold lugs, crown, and centre bracelet links with an Oystersteel case and outer bracelet links, giving the watch its warm two-tone character without the heft of a solid gold case. Against that warm metal palette, the silver lacquer dial set with diamond hour markers achieves a result that is simultaneously understated and distinctly jewelled — an effect that Rolex has cultivated in this family for decades.

The Calibre 2236 provides the mechanical foundation, housed in the 28mm Oyster case with a water resistance rating of 100 metres. This manufacture movement represents Rolex's most recent engineering effort for its smaller-cased ladies' watches, incorporating a Syloxi silicon hairspring for improved precision and magnetic resistance over the previous 2235. The Jubilee bracelet is the standard complement for this reference, its five-piece construction in Yellow Rolesor following the mixed-metal logic of the case. Each diamond on the dial is individually graded by Rolex's internal gemological team and set to precise alignment standards.

On the collector and pre-owned market, diamond-dial Lady-Datejust pieces in Yellow Rolesor represent one of the more approachable entry points into Rolex's jewelled watch segment. The 28mm size suits a broad range of wrist dimensions, while the current-generation 279xxx reference designation indicates the newer movement and updated case finishing. Buyers should prioritise lug condition and bracelet stretch as primary indicators of wear on pre-owned examples, with original crown and correct case back codes serving as authenticity benchmarks.
