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

Reference 279163 exemplifies the Lady-Datejust 28 in Yellow Rolesor — Rolex's term for the combination of Oystersteel on the case flanks, caseback and Oyster bracelet with 18 ct yellow gold on the bezel and crown. This material pairing, introduced to broaden the aesthetic range of the Datejust line, delivers the warmth of precious metal at the wrist without the full weight or price commitment of a monometallic gold case. The 28 mm Oyster case, water-resistant to 100 metres with a Twinlock crown, is polished and brushed to Rolex's customary exacting standard.

The silver dial deploys a diamond-set star motif as its defining motif — a configuration in which brilliant-cut diamonds radiate from a central hub to form a stylised asterisk, occupying the upper portion of the dial and commanding attention in any light. The remaining hour positions carry individual diamond markers, while the date aperture at three o'clock is enhanced by the Cyclops magnification lens. The combination of the bright white dial lacquer with yellow gold appliques and diamond brilliance produces a dial of considerable luminosity.

The movement within is Calibre 2236, a manufacture movement beating at 28,800 vph with a Syloxi silicon hairspring ensuring antimagnetic resilience and long-term rate stability. With a 55-hour power reserve and Paraflex shock protection, it is certified by COSC before casing. The three-link Oyster bracelet in Yellow Rolesor — Oystersteel centre links flanked by 18 ct yellow gold outer links — terminates in a concealed folding Oysterclasp with an Easylink comfort extension system.
