Measuring 31 mm in diameter, the round case of this Datejust 31 is crafted in White Rolesor, blending Oystersteel with white gold. The Oyster architecture features a monobloc middle case, a solid screw-down case back, and a screw-down Twinlock winding crown rated waterproof to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the bezel, which is set with diamonds.
The bright black dial is rendered with Roman numeral hour markers and displays the date via an instantaneous rapid-setting mechanism. Centre hour, minute, and seconds hands are joined by a stop-seconds function for precise time setting. The Oyster bracelet is composed of three-piece solid Oystersteel links and fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link.
Power comes from the perpetual, mechanical, self-winding Calibre 2236, a Manufacture Rolex movement offering approximately 55 hours of power reserve and precision of -2/+2 seconds per day after casing. The oscillator features a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers. The movement is COSC certified.
