Housed in a 31 mm Yellow Rolesor case — Rolex's own combination of Oystersteel and yellow gold — this Datejust 31 features a fluted bezel and a screw-down crown with Twinlock double waterproofness, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date, while the monobloc middle case and screw-down case back complete the Oyster architecture.
The dark grey dial is set with diamonds, with the large VI index featuring 11 diamonds alongside Roman numeral hour markers elsewhere. The three-piece solid-link Oyster bracelet, also rendered in Yellow Rolesor, fastens via a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link for a secure yet adaptable fit.
Inside beats the Calibre 2236, a perpetual mechanical self-winding movement from Manufacture Rolex, offering a power reserve of approximately 55 hours and a precision rating of -2/+2 seconds per day after casing. The oscillator employs a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers. The movement holds Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
