At 31 mm, this Datejust 31 wears a round Oyster case crafted from Everose Rolesor, combining Oystersteel and Everose gold in a monobloc middle case construction with a screw-down case back and screw-down Twinlock winding crown. The domed bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date window sits above a rosé-colour dial dressed with Roman numerals. Water resistance reaches 100 metres / 330 feet.
The three-piece solid-link Oyster bracelet shares the same Everose Rolesor composition and fastens via a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. Inside, the Manufacture Rolex Calibre 2236 — a perpetual, mechanical, self-winding movement — delivers bidirectional winding through a Perpetual rotor, an approximately 55-hour power reserve, and a precision rating of -2/+2 seconds per day after casing. The oscillator features a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers.
The movement carries Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing verification. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting.
