Housed in a 31 mm Oyster case crafted from Yellow Rolesor — a combination of Oystersteel and yellow gold — this Datejust 31 features a monobloc middle case, screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres. The fluted yellow gold bezel and scratch-resistant sapphire crystal with a Cyclops lens over the date complete the case architecture.
The black mother-of-pearl dial is set with diamonds held in 18 kt gold settings, creating a rich interplay of depth and brilliance. The three-piece solid-link Oyster bracelet is also rendered in Yellow Rolesor and fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link.
Powering the watch is the Calibre 2236, a perpetual mechanical self-winding movement from Manufacture Rolex. It features a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, approximately 55 hours of power reserve, and a precision rating of -2/+2 seconds per day after casing. The movement carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
