Housed in a 28mm round case crafted from 18kt yellow gold, this Lady-Datejust features Rolex's Oyster architecture — a monobloc middle case, solid screw-down case back, and a screw-down winding crown with Twinlock double waterproofness. A fluted bezel crowns the case, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the presentation. The watch is waterproof to 100 metres / 330 feet.
The silver dial is set with diamonds in 18kt gold settings, and the Roman IX numeral is itself rendered in 18kt gold set with eight diamonds. Power comes from the Calibre 2236, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor, a power reserve of approximately 55 hours, and a precision rating of -2/+2 seconds per day after casing. The oscillator features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers. The movement carries Superlative Chronometer certification — COSC certification followed by Rolex certification after casing.
The watch rides on an 18kt yellow gold Jubilee bracelet composed of five-piece links and secured by a concealed folding Crownclasp. The date complication offers instantaneous display with rapid setting, and stop-seconds allows for precise time setting. Reference 279178-0004.
