Measuring 31 mm across a round monobloc middle case crafted in White Rolesor — Rolex's combination of Oystersteel and white gold — this Datejust presents a domed bezel set with diamonds alongside a bright black dial bearing Roman numeral hour markers. Scratch-resistant sapphire crystal protects the face, with a Cyclops lens positioned over the date aperture for easy reading. The screw-down case back and Twinlock double-waterproofness winding crown contribute to water resistance of 100 metres / 330 feet.
Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. A Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers underpin the oscillator, while bidirectional winding via a Perpetual rotor delivers approximately 55 hours of power reserve. Precision is rated at -2/+2 seconds per day after casing, and the movement is COSC certified.
The Oystersteel Oyster bracelet features three-piece solid links and fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting.
