At 36 mm, this Datejust 36 features a round White Rolesor case — Rolex's combination of Oystersteel and white gold — topped by a diamond-set bezel. The bright blue dial is read through a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date aperture. A screw-down Twinlock double waterproofness crown and solid case back contribute to water resistance of 100 metres / 330 feet.
Power comes from the Calibre 3235, a perpetual, mechanical, self-winding movement manufactured by Rolex. It delivers a precision of -2/+2 seconds per day after casing — meeting the Superlative Chronometer standard, which encompasses both COSC certification and Rolex's own post-casing verification. The oscillator employs a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, with bidirectional self-winding via a Perpetual rotor and a power reserve of approximately 70 hours.
The watch rides on an Oystersteel Oyster bracelet composed of three-piece solid links, secured by a folding Oysterclasp with an Easylink 5 mm comfort extension link. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time setting.
