Reference 128236-0011 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 completes the case, which is waterproof to 100 metres.
The turquoise dial is set with diamonds, with hour markers in 18 kt gold set with 32 diamonds and Roman numerals VI and IX in 18 kt gold set with 24 diamonds. The platinum President bracelet, distinguished by its semi-circular three-piece links, secures with a concealed folding Crownclasp.
Inside runs the Rolex Calibre 3255, a COSC-certified perpetual mechanical self-winding movement offering a precision of -2/+2 seconds per day after casing and approximately 70 hours of power reserve. A paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to the movement's performance, while bidirectional winding via the Perpetual rotor keeps the watch running continuously during wear.
