Measuring 28mm across, the case is built in White Rolesor — Rolex's combination of Oystersteel and white gold — featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown that delivers waterproofness to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date, while the bezel is set with diamonds for additional brilliance.
The silver dial is dressed with Roman numeral hour markers, and the movement within is Rolex's Calibre 2236 — a perpetual, mechanical self-winding movement certified as a Superlative Chronometer, accurate to -2/+2 seconds per day after casing. A Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers support its precision, and bidirectional winding via the Perpetual rotor provides approximately 55 hours of power reserve.
The watch rides on an Oystersteel Oyster bracelet composed of three-piece solid links, secured by a folding Oysterclasp fitted with an Easylink 5mm comfort extension link for a well-fitted, adjustable wear experience. The reference number for this model is 279384RBR-0010.
