Measuring 31mm in diameter, this Datejust 31 is crafted entirely in 18kt Everose gold, from its round case to its President bracelet with semi-circular three-piece links and a concealed folding Crownclasp. The bezel is set with diamonds, while a scratch-resistant sapphire crystal — fitted with a Cyclops lens over the date — protects the dial below. A solid case back, screw-down Twinlock crown, and water resistance to 100 metres / 330 feet complete the case construction.
The silver dial is set with diamonds in 18kt gold settings, lending the piece a thoroughly jewellery-forward character. Underscoring the date display is the Cyclops lens for effortless legibility, and the dial carries centre hour, minute, and seconds hands alongside an instantaneous date with rapid setting and stop-seconds for precise time adjustment.
Power comes from the Rolex Calibre 2236, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor. The oscillator features a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers. A power reserve of approximately 55 hours, precision of -2/+2 seconds per day after casing, and Superlative Chronometer certification — encompassing both COSC and Rolex's own post-casing standards — round out the movement credentials.
