Reference 278285RBR presents the Datejust 31 in a 31 mm round case crafted from 18 kt Everose gold. The bezel is set with diamonds, while scratch-resistant sapphire crystal protects the dial and a Cyclops lens magnifies the date window. A solid case back and screw-down Twinlock crown contribute to water resistance rated to 100 metres / 330 feet.
The rosé dial is dressed with Roman numeral hour markers, lending a classic character to the warm Everose gold palette. The 18 kt Everose gold President bracelet features semi-circular three-piece links and closes with a concealed folding Crownclasp, completing the cohesive look of the piece.
Inside runs the perpetual, mechanical, self-winding Calibre 2236, a Manufacture Rolex movement delivering a precision of -2/+2 seconds per day after casing and an approximate power reserve of 55 hours. Bidirectional winding via the Perpetual rotor, a Syloxi silicon hairspring with patented geometry, and Paraflex shock absorbers round out the technical profile, with the movement holding Superlative Chronometer certification.
