At 31 mm, the Datejust 31 wears with quiet confidence. The round case is crafted in Everose Rolesor — Rolex's own combination of Oystersteel and Everose gold — and features a monobloc middle case, solid case back, and a screw-down crown equipped with the Twinlock double waterproofness system, delivering water resistance to 100 metres. The bezel is set with diamonds, while the scratch-resistant sapphire crystal carries a Cyclops lens positioned over the date window for effortless legibility.
The rosé dial is fitted with index stick hour markers and is paired with an Oyster bracelet constructed from three-piece solid links in matching Everose Rolesor. The folding Oysterclasp incorporates an Easylink 5 mm comfort extension link for a precise and comfortable fit on the wrist.
Inside beats the Caliber 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex. It features a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 55 hours. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for accurate time adjustment. The movement is COSC certified to a precision of -2/+2 seconds per day after casing.
