Reference 128238-0070 houses the Day-Date 36 in a 36 mm round case crafted from 18k yellow gold, featuring a fluted bezel, scratch-resistant sapphire crystal with a Cyclops lens over the date, and a solid case back. The Oyster architecture incorporates a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown, offering water resistance to 100 metres / 330 feet.
The green ombré dial is set with diamonds in 18kt gold settings, with baguette-cut diamonds placed at 6 and 9 o'clock, lending the face a layered, jewel-forward character. The 18kt yellow gold diamond-set President bracelet fastens via a concealed folding Crownclasp, completing the all-gold composition.
Inside runs the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex, rated to a precision of -2/+2 seconds per day after casing and certified as a Superlative Chronometer. It delivers approximately 70 hours of power reserve, bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, and high-performance Paraflex shock absorbers, alongside instantaneous day and date display with secure rapid-setting.
