Reference 128395TBR-0010 houses the Day-Date's 36 mm Oyster case in 18 kt Everose gold, featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for 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 Eisenkiesel dial is itself set with diamonds, and its hour markers in 18 kt gold carry 32 diamonds in total. The Roman numeral VI and IX are rendered in 18 kt gold and together set with 24 diamonds, lending the dial a richly detailed, gem-forward character.
Inside beats Rolex Calibre 3255, a perpetual mechanical self-winding movement certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. A paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, and a power reserve of approximately 70 hours round out the movement's specifications. The watch is worn on an 18 kt Everose gold President bracelet that fastens with a concealed folding Crownclasp.
