At 28mm, this Lady-Datejust presents its Oyster case in Yellow Rolesor, Rolex's signature blend of Oystersteel and yellow gold. The bezel is set with diamonds, while the screw-down winding crown employs a Twinlock double waterproofness system, and the scratch-resistant sapphire crystal carries a Cyclops lens over the date window. Water resistance is rated to 100 metres / 330 feet.
The silver dial is set with diamonds mounted in 18 kt gold settings, and the Roman IX numeral is itself rendered in 18 kt gold set with 8 diamonds. The five-piece-link Jubilee bracelet echoes the case in Yellow Rolesor and fastens with a concealed folding Crownclasp.
Powering the watch is 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, and the movement carries Superlative Chronometer certification — encompassing both COSC and Rolex certification after casing — achieving a precision of -2/+2 seconds per day.
