Rolex Day-Date 36 Everose Gold — Slate Diamond Dial | Ref. 128235

Reserved exclusively for precious metal cases — never produced in steel — the Day-Date has carried the informal designation 'the President's watch' since Dwight D. Eisenhower received one at his 1956 inauguration. Reference 128235 continues this tradition in 18 ct Everose gold, Rolex's proprietary rose gold alloy formulated with a small proportion of platinum to stabilise the characteristic blush hue against fading over time. The 36 mm Oyster case, entirely in Everose, presents the fluted bezel as a structural architectural element in its own right — twenty concentric grooves machined with metallurgical precision.

At the movement level, reference 128235 houses Calibre 3255 — a landmark in Rolex manufacture development. The Chronergy escapement, co-developed with the lever and escape wheel both fabricated in nickel-phosphorus, improves energy transfer efficiency by 15% over the previous generation while achieving near-total insensitivity to magnetic fields. The Syloxi-equivalent Rolex hairspring in this larger calibre — paired with a variable-inertia balance wheel adjustable via gold Microstella nuts — delivers chronometric precision to COSC-certified standards. Power reserve extends to 70 hours.

The slate diamond dial is a study in chromatic restraint within a context of gem-set luxury. The deep grey, almost charcoal ground absorbs light differently from hour to hour, shifting between warm and cool tones depending on ambient illumination. Diamond hour markers — selected for colour and clarity consistency — punctuate the dial with precise brilliance, while the twin apertures displaying day of the week (in full, at twelve o'clock) and date (at three, through the Cyclops lens) deliver the Day-Date's defining functional signature. The President bracelet, Rolex's most formal link design, closes the composition in matching Everose gold.
