At 31 mm, this Datejust 31 wears a round Oyster case built from Everose Rolesor, blending Oystersteel with Everose gold in both the case and bracelet. The domed bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial legible at a glance. A screw-down case back and a screw-down winding crown with Twinlock double waterproofness system deliver water resistance to 100 metres / 330 feet.
The white dial features Roman numeral hour markers, lending the piece a refined, classical character. The Jubilee bracelet — composed of five-piece links in matching Everose Rolesor — fastens via a concealed folding Crownclasp for a seamless profile on the wrist.
Power comes from the Rolex Calibre 2236, a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor and an approximately 55-hour power reserve. The oscillator employs a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, achieving a precision of -2/+2 sec/day after casing. The calibre carries Superlative Chronometer certification, reflecting both COSC testing and Rolex's own certification standards after casing.
