Reference 128239-0007 presents the Day-Date 36 in an Oyster case crafted from 18 kt white gold, measuring 36 mm across. The monobloc middle case is fitted with a screw-down case back and a screw-down Twinlock winding crown, offering waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case, while a fluted bezel frames the dial in characteristic Day-Date fashion.
The mother-of-pearl dial is set with diamonds in 18 kt gold settings, with baguette-cut diamonds positioned at 6 and 9 o'clock. Powering the watch is Rolex Calibre 3255, a perpetual, mechanical, self-winding movement with a bidirectional Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, and a power reserve of approximately 70 hours. Precision is rated at -2/+2 seconds per day after casing, and the movement is COSC certified.
The 18 kt white gold President bracelet, featuring semi-circular three-piece links, secures via a concealed folding Crownclasp. This example is from 2024 production.
