Rolex Day-Date 40 18ct White Gold — White MOP Diamond Set Dial | Ref. 228239

Reference 228239 — the Day-Date 40 in 18 ct white gold with fluted bezel and white mother-of-pearl diamond-set dial — is one of the most refined expressions of Rolex's presidential flagship in the current catalogue. Introduced as part of the Day-Date 40 generation that debuted in 2015, the 228xxx series brought with it the groundbreaking Calibre 3255 and a subtly enlarged 40 mm case profile that modernised the model's proportions while preserving its essential character. White gold and mother-of-pearl together project a cool, monochromatic luminosity that is among the most formal combinations Rolex produces.

Calibre 3255 represents Rolex's state-of-the-art self-winding movement as of this writing. It incorporates 14 patents, delivers a 70-hour power reserve — double that of many competitors — and features the Chronergy escapement, a redesigned lever-and-escape-wheel system that improves efficiency by 15% over its predecessor. The Parachrom hairspring and Paraflex shock absorbers further bolster reliability. The mother-of-pearl dial, set with diamond hour markers, is produced to the same exacting standards as all Rolex dials, with each stone individually inspected for colour and clarity before setting. The President bracelet in 18 ct white gold is exclusive to the Day-Date model.

A 2024 production example with box and papers, this 228239 represents the Day-Date 40 at its full potential: current calibre, complete accessories, and one of the most desirable dial configurations in the lineup. White gold Day-Date 40 references with MOP dials are perennially strong performers on the secondary market, favoured by collectors who prioritise the coolness of white precious metal over yellow or Everose gold. An exceptional proposition for the serious Rolex collector.
