At 28mm, this Lady-Datejust is built around a round Oyster case rendered in Everose Rolesor — Rolex's proprietary combination of Oystersteel and Everose gold. The case features a monobloc middle, screw-down case back, and a screw-down crown with Twinlock double waterproofness, delivering water resistance to 100 metres. Scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case, while the bezel is set entirely with diamonds.
The chocolate dial is itself set with diamonds mounted in 18 kt gold settings, lending depth and brilliance to every glance at the time. Date display is instantaneous with rapid setting, and a stop-seconds function allows for precise time synchronisation. The Oyster bracelet — three-piece solid links also in Everose Rolesor — fastens via a folding Oysterclasp fitted with an Easylink 5mm comfort extension link.
Power comes from Rolex Calibre 2236, a perpetual mechanical self-winding movement featuring a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers. It offers a power reserve of approximately 55 hours and achieves a precision of -2/+2 seconds per day after casing, certified as a Superlative Chronometer through both COSC and Rolex's own post-casing certification.
