At 31 mm, this Datejust 31 wears the rich aubergine dial with diamond-set hour markers, including a large VI set with 11 diamonds, and Roman numeral styling that lends a classical sensibility. The domed bezel is itself set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the glazing. The round Oyster case is built around a monobloc middle case with a solid case back and a screw-down Twinlock winding crown, offering water resistance to 100 metres / 330 feet.
The bracelet is an Oyster design composed of three-piece solid links in Everose Rolesor, fastened by a folding Oysterclasp with an Easylink 5 mm comfort extension link. Both the case and bracelet share the same combination of Oystersteel and Everose gold, giving the watch a consistent two-tone character throughout.
Power comes from 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, and a power reserve of approximately 55 hours. The movement carries Superlative Chronometer certification — encompassing both COSC and Rolex certification after casing — with a rated precision of -2/+2 seconds per day.
