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

Rolesor — Rolex's term for the harmonious pairing of Oystersteel and 18 ct gold — finds one of its most felicitous expressions in the Lady-Datejust 28, Reference 279163. Here, the durable corrosion-resistant Oystersteel of the case flanks is complemented by yellow gold crown, bezel, and Jubilee bracelet centre links, creating a two-tone visual rhythm that has characterised the Datejust family since Hans Wilsdorf first explored bi-metal construction in the 1940s. The 28 mm case diameter is optimised for feminine proportions, its triple-lock Twinlock winding crown ensuring the 100-metre water resistance mandated by Rolex's Oyster standard.

The lavender dial is among the most sought-after colour stories in the current Lady-Datejust palette — a soft violet hue that evokes both floral elegance and the gemstone amethyst. Diamond hour markers replace conventional indices, each brilliant-cut stone set flush and polished to maximise scintillation under ambient light. This combination of a coloured ground and diamond markers is a signature technique of Rolex's dial manufacture division in Geneva, where dials undergo independent quality audits before being mated to their movements. The domed bezel frames the dial with an uncluttered profile that draws attention inward toward the dial's chromatic richness.

Calibre 2236 powers the 279163, a movement developed specifically for the 26–31 mm Lady-Datejust models and featuring the Syloxi hairspring — a silicon component machined by photolithography to achieve extreme dimensional consistency and inherent resistance to magnetism. With a 55-hour power reserve and Superlative Chronometer certification, the 2236 represents a significant leap over the movements it succeeded. The Jubilee bracelet, with its characteristic five-link construction and folding Oysterclasp, provides both security and the elegant wrist drape that has made this bracelet a defining element of the Datejust identity for over seven decades.
