Presented in Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — the 31 mm round case of reference 278241-0025 is built around a monobloc middle case with a solid screw-down case back and a screw-down Twinlock winding crown. Scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the dial, while waterproofness extends to 100 metres / 330 feet.
The white mother-of-pearl dial is set with diamonds held in 18 kt gold settings, lending depth and brilliance to the face of the watch. Hour, minute, and seconds hands occupy the centre, accompanied by an instantaneous date display with rapid setting and a stop-seconds function for precise time adjustment. The matching Everose Rolesor Oyster bracelet features three-piece solid links and a folding Oysterclasp with an Easylink 5 mm comfort extension.
Power comes from the perpetual, mechanical, self-winding Calibre 2236, a Manufacture Rolex movement rated to -2/+2 seconds per day after casing and COSC certified. Its Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers provide oscillator stability, while bidirectional winding via the Perpetual rotor delivers a power reserve of approximately 55 hours.
