Measuring 31 mm across, this Datejust 31 is built around a Yellow Rolesor case — Rolex's combination of Oystersteel and yellow gold — featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown that delivers waterproofness to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date window, while the fluted yellow gold bezel adds a signature decorative accent to the profile.
The silver dial carries Roman numeral hour markers, with the large VI set with 11 diamonds, lending the piece a quietly ornate character. Completing the look is an Oyster bracelet in matching Yellow Rolesor, fitted with a folding Oysterclasp and an Easylink 5 mm comfort extension link for a precise, adjustable fit at the wrist.
Inside runs the Calibre 2236, a perpetual mechanical self-winding movement produced by Manufacture Rolex. It features a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, an approximately 55-hour power reserve, and a precision rating of -2/+2 seconds per day after casing. The movement holds Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
