Crafted entirely in 18kt white gold, the 31mm Oyster case features a monobloc middle case, screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, rated to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial perfectly legible, while the bezel is set with diamonds for an added layer of distinction.
The mint green dial is equipped with Rolex's Chromalight display, delivering long-lasting blue luminescence for clear readability in low light. Powering the watch is Calibre 2236 — a perpetual, mechanical, self-winding movement with a Syloxi silicon hairspring, Paraflex shock absorbers, and a power reserve of approximately 55 hours. The movement carries Superlative Chronometer certification, reflecting COSC testing followed by Rolex's own post-casing standards for precision of -2/+2 seconds per day.
The 18kt white gold President bracelet, featuring semi-circular three-piece links and a concealed folding Crownclasp, completes this Datejust 31 with a seamlessly elegant finish suited to both day and evening wear.
