At the heart of this Datejust 31 is an azzurro blue dial featuring a floral motif adorned with 24 diamonds set in 18 kt gold settings. The 31 mm round case is crafted in White Rolesor — Rolex's combination of Oystersteel and white gold — and features a fluted bezel, a solid case back, and a screw-down winding crown with Twinlock double waterproofness. A scratch-resistant sapphire crystal with a Cyclops lens over the date and water resistance to 100 metres / 330 feet complete the Oyster architecture.
The three-piece solid-link Oyster bracelet is rendered in Oystersteel and fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. Inside, the Calibre 2236 — a perpetual, mechanical, self-winding movement from Manufacture Rolex — delivers a precision of -2/+2 seconds per day after casing, a power reserve of approximately 55 hours, and bidirectional self-winding via a Perpetual rotor. The oscillator features a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers.
Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting. The movement is COSC certified, and the date complication is displayed through the Cyclops lens for easy legibility. Reference 278274-0035 is a compelling expression of the Datejust 31 lineup.
