The Rolex Day-Date 40 reference 228236-0018 is one of the rarest and most prestigious references in the modern Rolex catalog — a 40mm platinum case paired with an ice blue dial, representing the absolute pinnacle of the Day-Date lineage. Introduced as part of the Generation 12 update, the 228236 features the most advanced iteration of the Caliber 3255 movement and is presented in unworn condition from 2023, complete with the original box and warranty card — making it among the freshest examples available on the secondary market. The 950 platinum Oyster case delivers the unmistakable presence of the world’s most precious watch metal: a cool, substantial weight and a lustrous finish that distinguishes it from all other precious-metal Rolex watches. The fluted platinum bezel — a signature of the Day-Date since its inception — catches light with a brilliant, highly polished surface contrasting the satin-brushed case flanks. The ice blue dial, produced exclusively for platinum references, is a subtle silver-blue tone that shifts with ambient lighting, accented by the Chromalight display with long-lasting blue luminescence. Behind the Cyclops lens at 3 o’clock, the day and date are displayed in their respective windows — the Day-Date’s defining feature since 1956. Powering the Day-Date 228236 is the Caliber 3255, a Manufacture movement introduced with the Generation 12 updates. It incorporates the Chronergy escapement, a paramagnetic blue Parachrom hairspring, and high-performance Paraflex shock absorbers, delivering -2/ 2 seconds per day accuracy with an approximately 70-hour power reserve. The platinum President bracelet with its concealed folding Crownclasp and semi-circular three-piece links completes the most prestigious package Rolex offers — a watch that has adorned the wrists of world leaders, captains of industry, and discerning collectors for seven decades.
