Measuring 36 mm across, the round case is crafted in White Rolesor — Rolex's combination of Oystersteel and white gold — and topped with a diamond-set bezel. A scratch-resistant sapphire crystal with a Cyclops lens over the date protects the dial, while a solid case back and screw-down Twinlock double waterproofness system deliver water resistance to 100 metres / 330 feet.
The white mother-of-pearl dial is set with diamonds secured in 18 kt gold settings, and a Cyclops lens magnifies the instantaneous date display. Hour, minute, and seconds hands offer clear legibility, complemented by stop-seconds functionality for precise time setting.
Inside beats Calibre 3235, a perpetual, mechanical, self-winding movement manufactured by Rolex, rated to a precision of -2/+2 seconds per day after casing and certified as a Superlative Chronometer. A paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and an approximately 70-hour power reserve round out the movement's specification.
