Rolex Day-Date 40 Yellow Gold — White MOP Diamond-Set Dial | Ref. 228238

Introduced with the current-generation Day-Date 40, Ref. 228238 in solid 18ct yellow gold with a white mother-of-pearl diamond-set dial represents the flagship expression of Rolex's Presidents' watch. The 40mm case — an enlargement from the historic 36mm format — gives the Day-Date a contemporary presence on the wrist while retaining the full-gold construction and fluted bezel that have defined the model since 1956. The white MOP dial, with its organic luminescence and factory-set diamond hour markers, delivers a level of finishing that sits firmly in the realm of fine jewellery watchmaking.

Power comes from Calibre 3255, one of Rolex's most technically advanced in-house movements, offering a 70-hour power reserve through an optimised barrel and Chronergy escapement — a patented system delivering 15% greater efficiency than conventional lever escapements. This 2024-production example is supplied with original box and papers, confirming its status as a complete, unworn or near-unworn reference. The President bracelet in 18ct yellow gold, with its characteristic three-piece semi-circular links, remains among the most recognised bracelet designs in watchmaking.

This configuration — full yellow gold, fluted bezel, mother-of-pearl diamond dial, complete set from 2024 — is precisely what institutional collectors and serious Day-Date enthusiasts seek. Complete-set Ref. 228238 examples command sustained premiums on the secondary market, and the diamond-set MOP dial elevates desirability further. An unambiguous statement piece for those who appreciate both horological substance and material grandeur.
