At 28 mm, the Oyster case of this Lady-Datejust is constructed from Yellow Rolesor — Rolex's combination of Oystersteel and yellow gold — featuring a domed bezel, a screw-down winding crown with Twinlock double waterproofness, and a scratch-resistant sapphire crystal with a Cyclops lens positioned over the date. The monobloc middle case and screw-down case back deliver waterproofness to 100 metres / 330 feet.
The champagne-colour dial is set with diamonds, while the Roman IX numeral is rendered in 18 kt gold and set with 8 diamonds — each stone held in 18 kt gold settings. The Jubilee bracelet, also in Yellow Rolesor with five-piece links, fastens via a concealed folding Crownclasp for a secure and refined fit on the wrist.
Power comes from the Caliber 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. It features a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 55 hours. Precision is rated at -2/+2 seconds per day after casing, meeting Superlative Chronometer standards through both COSC and subsequent Rolex certification.
