Rolex Day-Date 40 White Gold — Black Baguette Diamond Dial, Fluted Bezel | Ref. 228239

Introduced in 1956 as the first wristwatch to display both the date and the full day of the week, the Day-Date has remained the definitive emblem of Rolex's prestige hierarchy. Reference 228239 brings this legacy into the present with an 18 ct white gold 40 mm Oyster case, its screw-down caseback engraved with characteristic Rolex fluting, and an 18 ct white gold fluted bezel whose twenty finely knurled facets catch light with commanding authority.

The black dial is set with ten baguette-cut diamond hour markers arranged in a disciplined constellation against the deep lacquered ground — a composition that balances opulence and legibility with practiced refinement. A sapphire crystal with double anti-reflective treatment and a Cyclops lens over the date aperture ensures clear readability under any lighting condition, while the President bracelet — crafted exclusively for the Day-Date — completes the ensemble with its signature three-piece solid links and concealed Crownclasp.

At the heart of this reference beats Calibre 3255, Rolex's most advanced self-winding movement. Incorporating a Chronergy escapement for superior energy efficiency, a Syloxi silicon hairspring for magnetic resilience, and a 70-hour power reserve, it represents the current apogee of the brand's manufacture capability. Stop-seconds for precise synchronisation and instantaneous day and date displays round out a movement that is as technically distinguished as the case that houses it.
