Sized at 31 mm, this Datejust 31 is built around a round White Rolesor case featuring a monobloc middle, screw-down case back, and a Twinlock screw-down winding crown. The bezel is domed and set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date window sits above the crisp white dial. Water resistance reaches 100 metres / 330 feet.
Inside runs the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex. Beating with a Syloxi silicon hairspring and Paraflex shock absorbers, it delivers a precision of -2/+2 seconds per day after casing and a power reserve of approximately 55 hours. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time-setting. The movement is COSC certified.
The Oystersteel Jubilee bracelet with its five-piece links fastens via a concealed folding Crownclasp, lending the watch its characteristic refined silhouette. Roman numerals appear on the white dial, completing a look that blends diamond details with the enduring proportions of the Datejust 31.
