At 31 mm, this Datejust 31 wears a round monobloc case crafted in White Rolesor, blending Oystersteel and white gold. The fluted bezel crowns the case, while a screw-down case back and a Twinlock double waterproofness winding crown contribute to water resistance rated to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case architecture.
The bright blue dial features Roman numeral hour markers and an instantaneous date display with rapid setting. Inside, the Calibre 2236 — a perpetual, mechanical, self-winding movement manufactured by Rolex — runs to a precision of -2/+2 seconds per day after casing, delivers approximately 55 hours of power reserve, and incorporates a Syloxi silicon hairspring with patented geometry alongside Paraflex shock absorbers. The movement is COSC certified and winds bidirectionally via a Perpetual rotor.
The Oystersteel Oyster bracelet is composed of three-piece solid links and fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link, offering both security and on-the-fly adjustability.
