Rolex Day-Date Platinum — Blue Roman Dial | Ref. 128236

Platinum is the rarest and most precious metal in the Rolex Day-Date portfolio, reserved exclusively for the 36 mm case size and immediately identifiable by its distinctive ice-blue dial — a dial colour unique to Rolex's platinum Day-Date models and not offered in any other metal. Reference 128236 presents this distinguished combination in its most legible and traditional form: a blue dial with polished Roman numeral hour indices that evoke the classical watch dials of Geneva's finest maisons, set against the cool, naturally white lustre of 950 platinum that requires no plating and will never fade or tarnish.

The movement is the Rolex Calibre 3255, whose specification represents a substantial advancement over the 3135 it replaced. Fourteen patent-protected innovations include the Chronergy escapement for superior energy efficiency, a new barrel design that contributes to the 70-hour power reserve, and a Paraplex hairspring with a terminal curve developed using complex mathematical models to achieve near-perfect isochronism. The regulating organ as a whole is robust and highly resistant to magnetic fields. Superlative Chronometer status guarantees a daily rate of -2/+2 seconds, tested in real-world conditions after the watch has been cased.

The President bracelet in platinum — machined from the same solid precious metal as the case — fastens via the Crownclasp. The fluted bezel, also in platinum, catches light with a crisp, architectural regularity that complements the Roman dial's formal character. Among Day-Date references, platinum models occupy the summit of the collection: they are produced in smaller quantities, command a premium on the secondary market, and carry an immediate visual distinction that communicates their rarity to those who know. Reference 128236 is a watch for the collector who insists on the absolute best that Rolex offers.
