Reference 128238-0088 presents the Day-Date 36 in a 36mm round Oyster case crafted from 18K yellow gold, dressed with a fluted bezel and protected by scratch-resistant sapphire crystal with a Cyclops lens over the date. The case architecture follows Rolex's monobloc construction with a solid case back and screw-down crown featuring the Twinlock double waterproofness system, offering water resistance to 100 metres / 330 feet.
The carnelian dial is set with diamonds throughout: hour markers in 18K gold carry 32 diamonds, while the Roman VI and IX numerals in 18K gold are each set with a further 24 diamonds. The 18K yellow gold President bracelet, distinguished by its semi-circular three-piece links, fastens with a concealed folding Crownclasp.
Power comes from Rolex Calibre 3255, a perpetual mechanical self-winding movement delivering a precision of -2/+2 seconds per day after casing and approximately 70 hours of power reserve. The oscillator features a paramagnetic blue Parachrom hairspring alongside high-performance Paraflex shock absorbers, and the calibre holds Superlative Chronometer certification combining COSC and Rolex's own post-casing standards. This piece is unworn and comes complete with the original Rolex box and 2023 papers.
