Reference 128345RBR-0028 presents the Day-Date in a 36mm case crafted from 18 kt Everose gold, featuring a monobloc middle case, screw-down case back, and a screw-down winding crown with Twinlock double waterproofness. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance extends to 100 metres / 330 feet.
The white mother-of-pearl dial is set with diamonds in 18 kt gold settings, with baguette-cut diamonds positioned at 6 and 9 o'clock for added refinement. The 18 kt Everose gold President bracelet with semi-circular three-piece links fastens via a concealed folding Crownclasp, maintaining the clean lines the design is known for.
Powering the watch is Rolex Calibre 3255, a perpetual mechanical self-winding movement with a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 70 hours. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers. The movement holds Superlative Chronometer certification, reflecting both COSC testing and Rolex certification after casing.
