At 31 mm, this Datejust 31 wears the hallmark round Oyster case crafted in White Rolesor, combining Oystersteel with white gold. The domed bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date and a screw-down winding crown with Twinlock double waterproofness system keep the case sealed to 100 metres / 330 feet. A solid case back and monobloc middle case complete the Oyster architecture.
The bright blue dial features Roman numeral hour markers and an instantaneous date display with rapid setting. The Oyster bracelet is composed of three-piece solid links in Oystersteel and fastens with a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link.
Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement by Manufacture Rolex. It delivers a precision of -2/+2 seconds per day after casing, a power reserve of approximately 55 hours, and features a Syloxi silicon hairspring with patented geometry alongside high-performance Paraflex shock absorbers. The movement is COSC certified and winds bidirectionally via a Perpetual rotor.
