Housed in a round 31 mm case crafted from 18 kt yellow gold, this Datejust 31 features the classic Oyster architecture — a monobloc middle case, solid case back, and screw-down winding crown equipped with Rolex's Twinlock double waterproofness system. Scratch-resistant sapphire crystal with a Cyclops lens over the date protects the dial, while water resistance extends to 100 metres / 330 feet.
The olive green dial is set with diamonds throughout, with the large VI marker alone accented by 11 diamonds, and Roman numeral hour markers completing the composition. A fluted bezel in 18 kt yellow gold frames the dial, lending the piece its distinctly formal character. The 18 kt yellow gold President bracelet, defined by its semi-circular three-piece links, fastens with a concealed folding Crownclasp.
Inside runs the perpetual, mechanical, self-winding Calibre 2236 — a Manufacture Rolex movement rated to -2/+2 seconds per day after casing and COSC certified. A Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, and bidirectional winding via a Perpetual rotor deliver a power reserve of approximately 55 hours. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment.
