Housed in a round 31 mm Oyster case of 18 kt yellow gold, this Datejust 31 features a monobloc middle case, solid case back, and a screw-down winding crown secured by the Twinlock double waterproofness system. Scratch-resistant sapphire crystal with a Cyclops lens over the date window tops the case, which is waterproof to 100 metres / 330 feet.
The white dial is dressed with Roman numeral hour markers, while a fluted bezel in 18 kt yellow gold frames the composition. The 18 kt yellow gold President bracelet — distinguished by its semi-circular three-piece links — fastens via a concealed folding Crownclasp for a refined, seamless look on the wrist.
Powering the watch is the perpetual, mechanical, self-winding Calibre 2236, Manufacture Rolex, rated to a precision of -2/+2 seconds per day after casing and COSC certified. The movement winds bidirectionally via a Perpetual rotor, offers an approximately 55-hour power reserve, and features a Syloxi silicon hairspring with patented geometry alongside 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 adjustment.
