Measuring 28mm across, the Oyster case of this Lady-Datejust is crafted in Yellow Rolesor, Rolex's combination of Oystersteel and yellow gold. A fluted bezel frames the scratch-resistant sapphire crystal, which carries a Cyclops lens positioned over the date window. The screw-down winding crown features a Twinlock double waterproofness system, and the solid case back ensures water resistance to 100 metres / 330 feet.
The silver dial is set with diamonds secured in 18kt gold settings, lending quiet luminosity to the face. Hours, minutes, and seconds are displayed via central hands, accompanied by an instantaneous date with rapid setting and a stop-seconds function for precise time adjustment. The three-piece solid-link Oyster bracelet is rendered in the same Yellow Rolesor combination and fastens with a folding Oysterclasp fitted with an Easylink 5mm comfort extension link.
Power comes from Rolex Calibre 2236, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor. The oscillator employs a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers, delivering a precision of -2/+2 seconds per day after casing and an approximate power reserve of 55 hours. The movement holds Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
