At 36 mm, this Datejust carries a round Yellow Rolesor case built on Rolex's Oyster architecture: a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown delivering waterproofness to 100 metres / 330 feet. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with Cyclops lens over the date keeps the champagne-colour dial clearly in view. That dial features a Chromalight display with long-lasting blue luminescence for readability in low light.
Inside the solid case back, Calibre 3235 — a perpetual, mechanical, self-winding movement from Manufacture Rolex — runs the show. It beats with a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, delivers a precision of -2/+2 seconds per day after casing, and stores approximately 70 hours of power reserve via bidirectional self-winding through a Perpetual rotor. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting. The movement is COSC certified.
The Yellow Rolesor Oyster bracelet — also combining Oystersteel and yellow gold — secures with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link, allowing easy on-the-fly adjustment at the wrist.
