Rolex Datejust 31 Yellow Gold — Mother-of-Pearl Diamond Dial | Ref. 278248

Reference 278248 belongs to the current-generation Datejust 31, introduced with the broader Oyster Perpetual Datejust refresh that brought updated lugs, a more refined crown, and the latest-generation movement to the mid-size family. In yellow gold with a mother-of-pearl diamond-set dial, this configuration sits at the summit of decorative achievement within the 31 mm range — the iridescent dial surface providing an ever-shifting interplay of colour that transforms with each shift of ambient light.

At its core beats Calibre 2236, Rolex's dedicated manufacture movement for the Lady-Datejust and Datejust 31 segment. Cal 2236 features a silicon Syloxi hairspring, a component engineered entirely in-house that provides superior isochronism and resistance to magnetism compared to traditional alloy alternatives. The yellow gold Oyster case measures 31 mm and is water-resistant to 100 metres, finished with the brand's signature blend of polished and brushed surfaces to accentuate the case architecture.

For the collector oriented toward fine jewellery watches, the 278248 in mother-of-pearl and diamonds exemplifies Rolex's ability to construct precious-metal dress watches with genuine horological rigour beneath an overtly decorative exterior. The mother-of-pearl dial ensures that no two watches are truly identical, as the natural material varies subtly in its patterning, lending each example a degree of individuality rarely found in mass-produced luxury timepieces. Demand remains consistent among buyers who prize both wearability and long-term value retention.
