Housed in a 31mm round case crafted from 18kt yellow gold, this Datejust 31 features Rolex's Oyster architecture — a monobloc middle case paired with a screw-down case back and a screw-down Twinlock winding crown for waterproofness to 100 metres. Scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case, while the bezel is set with diamonds.
The silver dial is itself set with diamonds, held in 18kt gold settings, offering a look that carries through every detail of the watch. The President bracelet in 18kt yellow gold features semi-circular three-piece links and fastens with a concealed folding Crownclasp.
Powering the watch is Rolex Calibre 2236, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor and a power reserve of approximately 55 hours. The oscillator uses a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers, achieving a precision of -2/+2 seconds per day after casing. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time setting. The movement is COSC certified.
