Measuring 28 mm across, the Oyster case of this Lady-Datejust is built in Yellow Rolesor — Rolex's combination of Oystersteel and yellow gold — featuring a monobloc middle case, screw-down case back, and a screw-down winding crown secured by the Twinlock double waterproofness system. A domed bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date window, and the case is waterproof to 100 metres / 330 feet.
The champagne-colour dial is set with diamonds mounted in 18 kt gold settings, lending warmth and brilliance to the dial surface. The Jubilee bracelet, composed of five-piece links in matching Yellow Rolesor, secures via a concealed folding Crownclasp for a seamless look at the wrist.
Power comes from the Caliber 2236 — a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor and an approximate 55-hour power reserve. The oscillator features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, delivering a precision rating of -2/+2 seconds per day after casing. The movement carries Superlative Chronometer certification, reflecting COSC testing followed by Rolex's own post-casing standards.
