Measuring 31mm, this Datejust 31 is built around a round White Rolesor case — Rolex's combination of Oystersteel and white gold — featuring a monobloc middle case, solid case back, and a screw-down winding crown with Twinlock double waterproofness. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date window sits above the pink dial dressed with Roman numeral hour markers. Water resistance is rated to 100 metres / 330 feet.
The Oyster bracelet is constructed from three-piece solid Oystersteel links and fastens via a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. Powering the watch is the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex, offering a precision of -2/+2 seconds per day after casing and an approximate power reserve of 55 hours. The oscillator features a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers.
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, and the date complication is the sole additional indication on this elegantly restrained timepiece.
