Rolex Day-Date 36 White Gold — Bright Blue Diamond-Set Dial | Ref. 128239

Crafted entirely in 18ct white gold, reference 128239 presents one of the most arresting Day-Date configurations in the current collection: a bright blue dial with diamond-set hour markers that shimmer against the vivid lacquer ground. The fluted bezel — executed in the same white gold as the case and President bracelet — creates a unified, high-jewellery aesthetic that places this reference firmly within Rolex’s most prestigious tier. Blue dials have carried particular significance in the Day-Date lineage, evoking the kind of bold colour confidence that American presidents and global heads of state have worn since the reference debuted in 1956. The 2024 model year ensures contemporary movement specification throughout.

Calibre 3255 provides the mechanical backbone — Rolex’s current-generation manufacture calibre, representing the culmination of decades of in-house development. Its Chronergy escapement, crafted from nickel-phosphorus, functions with 15% greater efficiency than conventional lever designs, while the variable inertia balance wheel maintains precision without requiring the use of timing screws. The 70-hour power reserve means the watch sustains accurate timekeeping through an extended weekend off the wrist. Water resistance to 100 metres is certified by Rolex’s Superlative Chronometer designation, requiring accuracy within +/-2 seconds per day. Supplied with Box & Papers.

This configuration appeals strongly to the Day-Date collector who gravitates toward the classic 36mm proportions over the larger 40mm Day-Date 40, finding the original case size more faithful to the model’s heritage. White gold with blue dial is among the most requested Day-Date combinations in boutiques globally, and the diamond hour markers elevate the specification without crossing into full haute joaillerie territory. Compared to the yellow gold 128238 with blue dial, the white gold 128239 presents a cooler, more contemporary personality.
