Reference 128396TBR-0021 embodies the Day-Date at its most refined. The 36mm monobloc platinum case is fitted with a scratch-resistant sapphire crystal featuring a Cyclops lens over the date, a screw-down winding crown with Twinlock double waterproofness, and water resistance to 100 metres. The bezel is set with diamonds, lending the watch its distinctive presence on the wrist.
The blue ombré dial is dressed with Roman numeral markers, its gradient tone shifting with quiet drama across the surface. Beneath it sits 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. A paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and a bidirectional Perpetual rotor combine to deliver approximately 70 hours of power reserve.
The platinum President bracelet with semi-circular three-piece links fastens via a concealed folding Crownclasp, completing a watch whose every component is executed in the same precious metal. Instantaneous day and date displays appear in twin apertures, with stop-seconds functionality for precise time setting.
