At 31 mm, this Datejust 31 is built around a Yellow Rolesor construction — a combination of Oystersteel and yellow gold — for both the Oyster case and the Jubilee bracelet. The case features a monobloc middle, screw-down case back, and a screw-down Twinlock winding crown, delivering water resistance to 100 metres / 330 feet. A domed bezel and scratch-resistant sapphire crystal with a Cyclops lens over the date complete the case architecture.
The champagne-colour dial is set with diamonds mounted in 18 kt gold settings, adding a layer of warmth that complements the yellow gold elements throughout the watch. A concealed folding Crownclasp secures the five-piece link Jubilee bracelet at the wrist.
Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. It offers a precision rating of -2/+2 seconds per day after casing, an approximately 55-hour power reserve, bidirectional winding via a Perpetual rotor, and a Syloxi silicon hairspring with Paraflex shock absorbers. The movement holds Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
