Reference 128348RBR-0026 presents the Day-Date 36 in a 36 mm Oyster case crafted from 18 kt yellow gold, with a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown ensuring waterproofness to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the warm champagne dial clearly legible.
That champagne dial is carried on the President bracelet — Rolex's semi-circular three-piece link design in 18 kt yellow gold — secured by a concealed folding Crownclasp. Together, the case and bracelet form a cohesive statement in yellow gold that the Day-Date has represented since its introduction.
Inside beats the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex offering a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 70 hours. A paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers underpin its reliability, while the movement displays the day and date instantaneously in apertures alongside centre hour, minute, and seconds hands.
