Crafted in Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — the 31 mm round case of this Datejust 31 (ref. 278241-0028) features a domed bezel, solid case back, and a screw-down winding crown with Twinlock double waterproofness. Scratch-resistant sapphire crystal with a Cyclops lens over the date window sits atop the case, which is waterproof to 100 metres / 330 feet.
The chocolate dial is set with diamonds held in 18 kt gold settings, creating a warm contrast against the two-tone Everose Rolesor construction. The five-piece-link Jubilee bracelet — also in Everose Rolesor — fastens with a concealed folding Crownclasp, lending the watch its signature refined silhouette.
Powering the watch is the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex. It offers a precision of -2/+2 seconds per day after casing, an approximately 55-hour power reserve via bidirectional winding through the Perpetual rotor, and features a Syloxi silicon hairspring with patented geometry alongside Paraflex shock absorbers. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time setting.
