Housed in a round 31mm case crafted from Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — this Datejust 31 features a monobloc middle case, solid screw-down case back, and a screw-down winding crown equipped with the Twinlock double waterproofness system. Scratch-resistant sapphire crystal with a Cyclops lens over the date completes the Oyster architecture, and the watch is waterproof to 100 metres / 330 feet.
The slate dial is framed by a domed bezel set with diamonds, lending the piece a distinctive character. The three-piece solid-link Oyster bracelet is rendered in matching Everose Rolesor and fastens via a folding Oysterclasp with an Easylink 5mm comfort extension link.
Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex. It beats with a Syloxi silicon hairspring featuring patented geometry and Paraflex shock absorbers, delivering a precision of -2/+2 seconds per day after casing and a power reserve of approximately 55 hours. The movement carries Superlative Chronometer certification, combining COSC testing with Rolex's own post-casing standards.
