Measuring 28mm across, this Lady-Datejust features a round Oyster case built around a monobloc middle case with a screw-down case back and screw-down Twinlock double waterproofness crown, offering water resistance to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the rosé-colour dial. Index hour markers are rendered in Rolex's Chromalight display, which emits a long-lasting blue luminescence for legibility in low light.
The case and three-piece solid-link Oyster bracelet share the same Everose Rolesor construction — that signature blend of Oystersteel and Everose gold — secured by a folding Oysterclasp fitted with an Easylink 5mm comfort extension link. Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex. It carries a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, approximately 55 hours of power reserve, and a precision rating of -2/+2 seconds per day after casing.
The Calibre 2236 is certified as a Superlative Chronometer, reflecting both COSC certification and Rolex's own testing standard after casing. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment.
