Crafted entirely in 18kt yellow gold, this 28mm Lady-Datejust presents a round Oyster case featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock double waterproofness winding crown, together delivering water resistance to 100 metres / 330 feet. The bezel is set with 44 brilliant-cut diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date window crowns the case.
The silver dial is set with diamonds in 18kt gold settings, and the Roman IX numeral is rendered in 18kt gold set with 8 diamonds, lending an additional layer of brilliance to the face. The President bracelet in 18kt yellow gold features the signature semi-circular three-piece links and fastens via a concealed folding Crownclasp for a seamless silhouette on the wrist.
Powering the watch is the Calibre 2236, a perpetual mechanical self-winding movement by Manufacture Rolex, beating with a Syloxi silicon hairspring of patented geometry and high-performance Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor provides an approximate 55-hour power reserve, and the movement is COSC certified to a precision of -2/+2 seconds per day after casing. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting.
