Housed in a 36 mm 18 kt white gold Oyster case with a fluted bezel, the Day-Date 36 (ref. 128239-0030) is built around Rolex's monobloc middle case construction, featuring a screw-down case back and a screw-down Twinlock winding crown for waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The pink opal dial is set with diamonds throughout: 32 diamonds adorn the hour markers in 18 kt gold, while the Roman VI and IX numerals — also in 18 kt gold — are set with an additional 24 diamonds. The bracelet is a diamond-set President in 18 kt white gold, fastened by a concealed folding Crownclasp.
Power comes from the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex, rated to a precision of -2/+2 seconds per day after casing and offering approximately 70 hours of power reserve. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, and the movement is COSC certified. Production year is 2024.
