Housed in a round 31 mm case of Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — this Datejust 31 features the brand's Oyster architecture: a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown that keeps water out to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the case.
The rosé-colour dial is paired with a fluted bezel in Everose gold, while the three-piece solid-link Oyster bracelet shares the same Everose Rolesor construction. A folding Oysterclasp with an Easylink 5 mm comfort extension link secures the bracelet on the wrist.
Powering the watch is the perpetual, mechanical, self-winding Calibre 2236 — a Manufacture Rolex movement with a Syloxi silicon hairspring of patented geometry, Paraflex shock absorbers, and a precision rating of -2/+2 seconds per day after casing. Bidirectional winding via the Perpetual rotor provides a power reserve of approximately 55 hours, with functions including instantaneous date with rapid setting and stop-seconds for precise time adjustment. The movement is COSC certified.
