The domed bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the case. A screw-down winding crown with Twinlock double waterproofness keeps the watch sealed to 100 metres, and the folding Oysterclasp includes an Easylink 5mm comfort extension link for a refined fit.\u003c\/p\u003e\u003cp\u003eThe white dial is dressed with Roman numeral hour markers, offering a classically elegant readout. Beneath it, the Calibre 2236 — a perpetual, mechanical, self-winding movement from Manufacture Rolex — beats with a Syloxi silicon hairspring of patented geometry and high-performance Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor provides approximately 55 hours of power reserve, and stop-seconds allows for precise time setting.\u003c\/p\u003e\u003cp\u003eCarrying Superlative Chronometer certification — earned through COSC testing followed by Rolex's own certification after casing — the movement delivers a precision of -2\/+2 seconds per day.
