At 31 mm in diameter, this Datejust 31 is built around a round White Rolesor case — Rolex's combination of Oystersteel and white gold — featuring a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown providing waterproofness to 100 metres / 330 feet. The fluted bezel and scratch-resistant sapphire crystal with a Cyclops lens over the date complete the case's refined profile.
The dark grey dial is set with diamonds in 18 kt gold settings, lending depth and brilliance to the watch face. The three-piece solid-link Oyster bracelet in Oystersteel secures via a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link, offering both security and wearability.
Powering the watch is the perpetual, mechanical, self-winding Calibre 2236, a Manufacture Rolex movement COSC certified to a precision of -2/+2 seconds per day after casing. It features a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, bidirectional self-winding via a Perpetual rotor, and a power reserve of approximately 55 hours, with functions including instantaneous date with rapid setting and stop-seconds for precise time adjustment.
