Measuring 36 mm across, the round case is constructed in Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — featuring a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown. Water resistance reaches 100 metres / 330 feet, and the scratch-resistant sapphire crystal carries a Cyclops lens that magnifies the date window for easy reading.
The white dial is rendered with a Chromalight display, whose long-lasting blue luminescence keeps the hour, minute, and seconds hands legible in low light. Date changes are instantaneous with a rapid-setting function, and a stop-seconds mechanism allows precise time setting to the second.
Inside runs the Calibre 3235 — a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, COSC certification, and a precision rating of -2/+2 seconds per day after casing. Power reserve stands at approximately 70 hours. The Oyster bracelet closes with a folding Oysterclasp featuring an Easylink 5 mm comfort extension link.
