Housed in a 28mm Oyster case crafted from 18kt white gold, this Lady-Datejust features a monobloc middle case with a screw-down case back and screw-down winding crown secured by Rolex's Twinlock double waterproofness system. The bezel is set with 44 brilliant-cut diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance extends to 100 metres / 330 feet.
The silver dial is marked with Roman numeral hour indicators, offering a classically legible face. The President bracelet, constructed from 18kt white gold with semi-circular three-piece links, fastens via a concealed folding Crownclasp for a seamless look on the wrist.
Power comes from the Calibre 2236, a perpetual mechanical self-winding movement of Manufacture Rolex. A Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers contribute to a precision rating of -2/+2 seconds per day after casing, and the movement carries Superlative Chronometer certification — combining COSC testing with Rolex's own post-casing verification. Power reserve is approximately 55 hours, with bidirectional winding via a Perpetual rotor.
