Rolex Lady-Datejust White Rolesor — White Mother-Of-Pearl Diamond Dial, 44-Diamond Bezel | Ref. 279384RBR

Among the most luminous configurations in the Lady-Datejust 28 range, reference 279384RBR in White Rolesor achieves a deliberate harmony of light and texture. The Oyster case in Oystersteel with 18 ct white gold crown, bezel setting and Jubilee bracelet centre links provides a cool, silvery foundation. Forty-four brilliant-cut diamonds set in the factory bezel encircle a White Mother-Of-Pearl dial that shifts from near-translucent white to warm cream and soft lavender as the light changes — an inherent variability that renders each example visually singular. Diamond hour markers extend the gem-set theme to the chapter ring.

Calibre 2236 drives the 279384RBR, the dedicated in-house movement developed by Rolex for the 28 mm Lady-Datejust family. The 2236's principal technical achievement is its Syloxi silicon hairspring, which provides superior magnetic resistance and thermal stability without the added weight of a traditional Glucydur balance. The movement operates at 28,800 vph, delivers a 55-hour power reserve and is certified to Rolex's Superlative Chronometer standard — a post-production accuracy specification of ±2 seconds per day that surpasses the COSC benchmark.

The 279384RBR occupies a genuinely special position in the collector landscape: an all-white expression that functions equally as a precision timepiece and a piece of jewellery wearable against formal attire. Factory-set pave bezels on Rolex watches attract particular scrutiny — stones sourced and set in-house to Rolex's gem-selection standards — and command consistent premiums over aftermarket modifications. The combination of White Rolesor, a diamond bezel and a Mother-Of-Pearl diamond dial ensures enduring demand well beyond its initial market release.
