Housed in a 36 mm platinum Oyster case with a fluted bezel, the Day-Date 128236-0003 is built around Rolex's monobloc middle case architecture, featuring a screw-down case back and a screw-down Twinlock winding crown for water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The dial is fully paved with diamonds and accented by 10 baguette-cut, rainbow-coloured sapphires at the hour positions, making it one of the most visually striking references in the Day-Date collection. Displaying the day and date in separate apertures via an instantaneous rapid-setting mechanism, the watch is driven by the Calibre 3255 — a perpetual, mechanical, self-winding movement manufactured by Rolex with a precision rating of -2/+2 seconds per day after casing, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, and approximately 70 hours of power reserve. The movement is COSC certified.
The platinum President bracelet with semi-circular three-piece links closes via a concealed folding Crownclasp, providing a refined and secure fit that complements the overall character of this reference.
