Reference 128238-0133 presents the Day-Date 36 in an 18K yellow gold Oyster case measuring 36 mm in diameter. The round case features a fluted bezel, solid case back, and a screw-down winding crown secured by the Twinlock double waterproofness system, offering water resistance to 100 metres / 330 feet. Scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The champagne-colour dial is set with 10 baguette-cut diamonds at the hour markers, lending the watch a refined decorative character. It is paired with an 18K yellow gold diamond-set President bracelet that fastens via a concealed folding Crownclasp.
Power comes from Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex. It delivers a precision of -2/+2 seconds per day after casing, a power reserve of approximately 70 hours, and features a paramagnetic blue Parachrom hairspring alongside Paraflex shock absorbers. The watch is a Superlative Chronometer, reflecting both COSC certification and Rolex's own certification after casing. This example comes as a complete set with original Rolex box and Rolex papers from 2023.
