Rolex Day-Date 40 Platinum — Roman Dial | Ref. 228236

Reference 228236 represents one of the most exclusive positions in the entire Rolex catalogue: the Day-Date 40 in platinum. Platinum is the sole material that Rolex uses for the Day-Date's ice-blue dial — a colour that exists nowhere else in the brand's portfolio and is chemically produced by the reaction of the dial lacquer with the platinum case environment during manufacturing. The Roman numeral hour markers on this reference provide a classical typographic register that has long been associated with the Day-Date's most formal expressions.

The Calibre 3255 powers 228236, delivering the full suite of current-generation technical achievements: the Chronergy escapement with 15% greater efficiency over its predecessor, the Syloxi silicon hairspring, a 70-hour power reserve, and Superlative Chronometer certification to ±2 seconds per day. The platinum Oyster case, at 40 mm, is paired with the President bracelet in platinum — a three-link construction machined from solid metal with a concealed Crownclasp deployment. Platinum's density gives the President bracelet a distinctive weight and drape that gold versions cannot fully replicate, and the metal's natural resistance to tarnishing requires no rhodium plating to maintain its white appearance.

Among Day-Date collectors, platinum 228236 is regarded as the apex expression of the current generation. Production volumes are lower than gold variants, and the ice-blue dial — inseparable from platinum — has achieved a near-mythological status in horological culture. Acquiring 228236 with box and papers represents a genuine long-position in the Day-Date market, with demand structurally exceeding retail availability.
