Housed in a 31 mm Oyster case crafted from Yellow Rolesor — Rolex's combination of Oystersteel and yellow gold — this Datejust 31 features a monobloc middle case, screw-down case back, and a screw-down winding crown with the Twinlock double waterproofness system. A domed bezel set with diamonds frames scratch-resistant sapphire crystal with a Cyclops lens over the date, and the watch is waterproof to 100 metres / 330 feet.
The dark grey dial is itself set with diamonds, with the large VI marker featuring 11 diamonds alongside Roman numeral hour indicators. The three-piece solid-link Oyster bracelet in matching Yellow Rolesor fastens via a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link.
Power comes from the Calibre 2236, a perpetual mechanical self-winding movement of Manufacture Rolex bearing Superlative Chronometer certification — combining COSC testing with Rolex's own post-casing standard — delivering a precision of -2/+2 seconds per day, a power reserve of approximately 55 hours, and a Syloxi silicon hairspring with Paraflex shock absorbers. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time setting.
