At 31 mm, this Datejust 31 is built around a round monobloc middle case crafted in Everose Rolesor — Rolex's blend of Oystersteel and Everose gold. The domed bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case front. A solid case back, screw-down case back and winding crown with Twinlock double waterproofness system deliver water resistance to 100 metres / 330 feet.
The rosé-colour dial sits behind the sapphire crystal, and the Oyster bracelet — also in Everose Rolesor — fastens via a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link. The bracelet's three-piece solid links carry the same warm two-tone character as the case.
Inside runs the Calibre 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. It features a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, a power reserve of approximately 55 hours, and a precision rating of -2/+2 seconds per day after casing. The movement holds Superlative Chronometer status, reflecting both COSC certification and Rolex's own post-casing certification.
