At 36 mm, the Datejust 36 wears the White Rolesor construction — Oystersteel paired with white gold — beneath a scratch-resistant sapphire crystal that carries a Cyclops lens directly over the date window. The bezel is set with diamonds, lending the watch its distinctive brilliance, while the solid case back and screw-down Twinlock double waterproofness crown contribute to water resistance rated to 100 metres / 330 feet.
The bright blue dial features a fluted motif pattern that plays with light in a way that complements the diamond-set bezel above it. Powering the watch is Rolex Calibre 3235, a perpetual, mechanical, self-winding movement with a bidirectional Perpetual rotor and a power reserve of approximately 70 hours. The oscillator employs a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, while precision is rated at -2/+2 seconds per day after casing — meeting the Superlative Chronometer standard combining COSC certification and Rolex's own post-casing verification.
On the wrist, the watch is secured by an Oystersteel Jubilee bracelet composed of five-piece links and finished with a folding Oysterclasp that incorporates an Easylink 5 mm comfort extension link for easy on-the-fly adjustment. Functions include center hour, minute, and seconds hands alongside an instantaneous date display with rapid setting and stop-seconds for precise time-setting.
