Rolex Lady-Datejust 28 Yellow Rolesor — Silver Index Dial | Ref. 279173

Yellow Rolesor — Rolex's term for the combination of Oystersteel and 18-carat yellow gold — gives Reference 279173 a classically composed two-tone character that has been central to Datejust identity since the 1940s. On the 28mm Lady-Datejust, the fluted yellow gold bezel sits atop a steel case, framing a silver dial with index hour markers for a clean, unembellished legibility. The Jubilee bracelet in matching Yellow Rolesor completes the look, its five-link construction providing a supple, jewellery-like drape on the wrist.

Inside the 28mm case, Calibre 2236 operates with Rolex's silicon Syloxi hairspring, offering improved antimagnetic performance and a 55-hour power reserve. The movement is certified as a Superlative Chronometer, held to the exacting standard of ±2 seconds per day — considerably tighter than COSC certification requires. The Oysterlock safety clasp on the Jubilee bracelet ensures secure wear, while the screw-down Triplock crown maintains waterproofing to 100 metres.

Reference 279173 speaks to collectors who appreciate Rolex's mastery of integrated, proportional design. The Yellow Rolesor configuration gives the piece broad wearability — it reads as dressy without the full weight of an all-gold watch, and the 28mm diameter suits smaller wrists elegantly. As the entry point into the Lady-Datejust's precious metal line, this reference offers strong value retention and consistent demand, supported by Rolex's ongoing production and the enduring appeal of the two-tone aesthetic.
