Crafted in Yellow Rolesor — Rolex's combination of Oystersteel and yellow gold — the 31 mm Oyster case of this Datejust 31 features a monobloc middle case, screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, rated to 100 metres / 330 feet. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display beneath.
The champagne dial is itself set with diamonds, with gem settings mounted in 18 kt gold, lending the piece a layered brilliance. The five-piece-link Jubilee bracelet in matching Yellow Rolesor fastens via a concealed folding Crownclasp, completing the refined aesthetic.
Inside beats the Calibre 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. It delivers a precision of -2/+2 seconds per day after casing — certified as a Superlative Chronometer through both COSC and Rolex's own post-casing certification — and offers an approximate power reserve of 55 hours. The oscillator employs a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers, with bidirectional self-winding via a Perpetual rotor.
