Crafted in 18 kt yellow gold, this 28 mm Lady-Datejust features a round Oyster case with a solid case back, a screw-down winding crown operating a Twinlock double waterproofness system, and scratch-resistant sapphire crystal fitted with a Cyclops lens over the date window. The case is waterproof to 100 metres / 330 feet.
The silver dial is set with diamonds in 18 kt gold settings, with the Roman IX position accented by a dedicated 18 kt gold marker set with 8 diamonds. A fluted bezel completes the look, while the President bracelet — built from semi-circular three-piece links in 18 kt yellow gold — fastens with a concealed folding Crownclasp.
Inside runs Calibre 2236, a perpetual mechanical self-winding movement from Manufacture Rolex offering approximately 55 hours of power reserve and a precision 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, with bidirectional winding via a Perpetual rotor. Functions include date with instantaneous rapid setting and stop-seconds for precise time adjustment. The watch carries Superlative Chronometer designation, reflecting both COSC certification and Rolex's own post-casing standards.
