At 28 mm, the Lady-Datejust reference 279174-0017 is built around an Oyster case crafted in White Rolesor, blending Oystersteel with white gold. The fluted bezel frames a pink dial marked with Roman numerals, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the presentation. A screw-down crown with Twinlock double waterproofness keeps the case sealed to 100 metres / 330 feet.
The five-piece link Jubilee bracelet in Oystersteel fastens with a concealed folding Crownclasp, lending the watch its characteristic elegance at the wrist. Inside, the self-winding Caliber 2236 — a perpetual, mechanical movement from Manufacture Rolex — delivers a precision of -2/+2 seconds per day after casing and an approximate power reserve of 55 hours via bidirectional winding through a Perpetual rotor.
The caliber features a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers, and carries Superlative Chronometer certification reflecting both COSC standards and Rolex's own post-casing testing. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment.
