At 31 mm, this Datejust 31 carries a round monobloc middle case crafted in White Rolesor, the distinctive Rolex combination of Oystersteel and white gold. The bezel is set with diamonds, while the screw-down case back and screw-down Twinlock winding crown ensure waterproofness to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display.
The silver dial is itself set with diamonds held in 18 kt gold settings, creating a luminous surface that catches the light at every angle. The Oystersteel Jubilee bracelet — featuring five-piece links and a concealed folding Crownclasp — completes the look with the elegance that has defined this bracelet style since its introduction alongside the Datejust.
Inside beats the Calibre 2236, a perpetual, mechanical, self-winding movement produced by Rolex. It offers bidirectional winding via a Perpetual rotor, a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, and a power reserve of approximately 55 hours. Precision is rated at -2/+2 seconds per day after casing, and the movement is COSC certified. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting.
