Crafted in White Rolesor — a combination of Oystersteel and white gold — the 31 mm round case of this Datejust 31 follows Rolex's Oyster architecture with a monobloc middle case, solid screw-down case back, and screw-down winding crown featuring the Twinlock double waterproofness system. The domed bezel is set with diamonds, and a scratch-resistant sapphire crystal with a Cyclops lens over the date window sits above. The watch is waterproof to 100 metres / 330 feet.
The white mother-of-pearl dial is itself set with diamonds mounted in 18 kt gold settings, lending depth and luminosity to the face. Timekeeping functions include centre hour, minute, and seconds hands alongside an instantaneous date with rapid setting and stop-seconds for precise time adjustment. The Jubilee bracelet in Oystersteel features five-piece links and fastens via a concealed folding Crownclasp.
Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement of Manufacture Rolex bearing COSC certification and a precision rating of -2/+2 seconds per day after casing. The oscillator uses a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, with bidirectional self-winding via a Perpetual rotor delivering approximately 55 hours of power reserve.
