Reference 128235-0040 presents the Day-Date 36 in an Oyster case crafted from 18 kt Everose gold, measuring 36 mm across. The fluted bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date aperture, while the screw-down winding crown employs a Twinlock double waterproofness system for resistance to 100 metres / 330 feet.
At the centre of attention is the diamond-paved dial, set with 10 baguette-cut, rainbow-coloured sapphires at the hour positions. The 18 kt Everose gold diamond-set President bracelet secures via a concealed folding Crownclasp, giving the piece a unified, jewel-forward appearance throughout.
Inside beats the Calibre 3255, a perpetual, mechanical, self-winding movement produced by Rolex, offering approximately 70 hours of power reserve and a precision rating of -2/+2 seconds per day after casing. A paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers contribute to its robustness, and the movement carries Superlative Chronometer certification — combining COSC testing with Rolex's own post-casing verification.
