Housed in a 28 mm Oyster case crafted from White Rolesor, a combination of Oystersteel and white gold, the Lady-Datejust 279174-0004 features a monobloc middle case with a screw-down case back and screw-down winding crown secured by Rolex's Twinlock double waterproofness system. A fluted bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date, and the watch is waterproof to 100 metres / 330 feet.
The pink dial is set with diamonds in 18 kt gold settings, lending each hour a quiet brilliance. The three-piece solid-link Oystersteel Oyster bracelet fastens with a folding Oysterclasp incorporating an Easylink 5 mm comfort extension link, allowing for a precise and comfortable fit.
Powering the watch is the perpetual, mechanical, self-winding Caliber 2236, a Manufacture Rolex movement with a Syloxi silicon hairspring of patented geometry and Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor delivers a power reserve of approximately 55 hours, while stop-seconds and rapid date setting add everyday practicality. The movement carries Superlative Chronometer certification — COSC testing followed by Rolex certification after casing — to a precision of -2/+2 seconds per day.
