Rolex Day-Date 36 Platinum — Ombré Diamond Dial | Ref. 128236

Platinum is the sole case metal for the Day-Date 36's most prestigious configurations, and Ref. 128236 deploys it in service of one of the most visually arresting dial treatments in the current Rolex catalogue: an ombré diamond-set dial in which stones of graduated colour intensity create a tonal transition across the dial surface. This technique demands exceptional consistency in stone selection and placement, and it places Ref. 128236 at the intersection of haute horlogerie and haute joaillerie in a way that very few production watches achieve.

Calibre 3255 powers the 128236—Rolex's most advanced manufacture movement, featuring the Chronergy escapement, a 70-hour power reserve, and a total rebuild of the barrel, gear train, and escapement relative to the preceding calibre 3155. The Day-Date's dual display—instantaneous day disc and date window at 3 o'clock—demands movement architecture of particular precision, and the 3255's rapid-setting mechanism for both complications operates with a positive, tactile action. The President bracelet in platinum, with its characteristic three-piece semi-circular links, is exclusive to this material and Day-Date configuration.

A platinum Day-Date 36 with ombré diamond dial represents the highest expression of the Day-Date concept in this case size. The reference attracts collectors for whom horological prestige, material rarity, and gem-set artisanship are simultaneously important. Platinum Day-Date references hold value with particular consistency in the secondary market, historically outperforming their gold counterparts on a price-stability basis.
