Rolex Day-Date 40 White Gold — Olive Green Bevelled Roman Dial | Ref. 228349RBR

The Day-Date 40 has carried the mantle of Rolex's flagship dress watch since the case diameter expanded from 36 to 40 mm in 2015, and reference 228349RBR in 18ct white gold with a diamond-set bezel represents one of the most opulent expressions of that evolution. The olive green dial with bevelled Roman numeral indices occupies a particularly coveted space in the Day-Date palette — the warm earthy green tone provides a depth and individuality that has proven enormously popular among collectors, its rich hue shifting subtly under different lighting conditions and harmonising unexpectedly well with the cool white gold case.

The movement inside is the Rolex Calibre 3255, the most capable self-winding movement Rolex has produced for a dress watch. Its 70-hour power reserve — exceptional for a watch of this type — is accompanied by the Chronergy escapement, a patented lever and escape wheel design offering 15% greater energy efficiency than conventional lever escapements. The Paraplex hairspring and optimised balance wheel geometry ensure isochronal precision across the full arc of oscillation. Performance is certified at -2/+2 seconds per day by Rolex's own Superlative Chronometer testing protocols, which exceed the requirements of COSC.

The President bracelet in 18ct white gold — named in honour of Dwight D. Eisenhower, to whom Rolex presented a gold Day-Date in 1956 — fastens via the concealed Crownclasp with a comfort extension of 5 mm. Reference 228349RBR's diamond-set bezel adds further jewellery distinction, framing the olive green dial in a constellation of brilliant-cut stones. This is a watch that consolidates horological mastery, precious materials, and bold dial artistry into a single, definitive statement — befitting the watch that Rolex has long marketed as the watch worn by those who shape the world.
