Housed in a round 28mm Oyster case of 18kt yellow gold, this Lady-Datejust is built around a monobloc middle case with a solid screw-down case back and a screw-down winding crown featuring Rolex's Twinlock double waterproofness system. Scratch-resistant sapphire crystal protects the dial, with a Cyclops lens magnifying the date display, and the case is waterproof to 100 metres / 330 feet.
The silver dial is appointed with diamonds set in 18kt gold settings, while the fluted bezel frames the dial with characteristic elegance. The five-piece link Jubilee bracelet in 18kt yellow gold secures via a concealed folding Crownclasp, completing the watch's refined character.
Power comes from Rolex Calibre 2236, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor and a power reserve of approximately 55 hours. The oscillator features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, delivering a precision of -2/+2 seconds per day after casing. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time setting. The movement carries Superlative Chronometer certification, combining COSC and Rolex certification after casing.
