Reference 128236-0023 houses a 36 mm platinum Oyster case with a fluted bezel, solid case back, and a screw-down winding crown featuring the Twinlock double waterproofness system. Scratch-resistant sapphire crystal with a Cyclops lens over the date tops the case, and water resistance extends to 100 metres / 330 feet.
The bright blue dial is set with 10 baguette-cut diamonds at the hour positions, giving the watch a distinctly jewel-forward character. A platinum President bracelet composed of semi-circular three-piece links secures via a concealed folding Crownclasp.
Inside beats the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex. Bidirectional winding via the Perpetual rotor delivers approximately 70 hours of power reserve, while a paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to a precision rating of -2/+2 seconds per day after casing. The movement is COSC certified and displays the day and date through instantaneous apertures with secure rapid-setting.
