At 31mm, this Datejust 31 presents a round Oyster case crafted from Everose Rolesor — a blend of Oystersteel and Everose gold — with a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown for water resistance to 100 metres. A scratch-resistant sapphire crystal tops the dial, complete with a Cyclops lens positioned over the date window.
The dial itself is white mother-of-pearl set with diamonds in 18kt gold settings, while the domed bezel is also set with diamonds, lending the piece a layered brilliance. The five-piece-link Jubilee bracelet, rendered in matching Everose Rolesor, fastens with a concealed folding Crownclasp for a seamless profile on the wrist.
Power comes from the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex, featuring a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers. The movement delivers a precision rating of -2/+2 seconds per day after casing, a power reserve of approximately 55 hours, and holds Superlative Chronometer certification — combining COSC standards with Rolex's own post-casing verification. Functions include center hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment.
