Rolex Lady-Datejust Gold — Diamond Bezel Sundust Roman Dial | Ref. 279135RBR

Few Rolex references balance decorative ambition with restrained elegance as successfully as the 279135RBR. The sundust dial — Rolex's warm, rose-inflected champagne lacquer — carries Roman numeral hour markers that lend classical structure to what is otherwise a richly ornamented piece. The RBR designation confirms a factory diamond-set bezel, with 44 brilliant-cut diamonds replacing the traditional fluted or smooth bezel ring entirely, catching light from every angle without overwhelming the dial's quiet warmth.

Calibre 2236 drives this 28mm reference — a movement purpose-built for the Lady-Datejust platform, incorporating a Syloxi silicon hairspring and delivering a 55-hour power reserve. The case material — Everose gold or yellow gold depending on the specific configuration — is crafted from Rolex's proprietary 18k alloy, formulated for fade resistance over time. The President or Jubilee bracelet in matching precious metal completes an ensemble where every component has been selected and finished to the same exacting standard as the movement itself.

The 279135RBR appeals to collectors who regard a Rolex as both a horological instrument and a jewellery piece without apology. The diamond bezel and sundust dial combination is among the more expressive configurations available in the current Lady-Datejust range, yet it maintains the legibility and wearability that defines the Datejust family. Demand for this reference remains consistent, and factory diamond bezels carry a premium that holds well in the secondary market, particularly when accompanied by original box and papers.
