Reference 128345RBR-0070 presents the Day-Date in a 36 mm Oyster case crafted from 18 kt Everose gold, featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown that ensures waterproofness to 100 metres. The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The white dial is dressed with Roman numeral hour markers and displays both the day and date through instantaneous apertures with secure rapid-setting. Beneath it, the Calibre 3255 — a perpetual, mechanical, self-winding movement manufactured by Rolex — delivers a precision of -2/+2 seconds per day after casing, a power reserve of approximately 70 hours, and carries Superlative Chronometer certification. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers.
The watch rides on an 18 kt Everose gold President bracelet with semi-circular three-piece links, fastening via a concealed folding Crownclasp for a clean, seamless profile on the wrist.
