Reference 128239-0026 presents the Day-Date 36 in an Oyster case measuring 36 mm, crafted from 18 kt white gold with a fluted bezel. The monobloc middle case features a solid case back and a screw-down winding crown with a Twinlock double waterproofness system, offering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The mother-of-pearl dial is set with diamonds in 18 kt gold settings, with baguette-cut diamonds marking 6 and 9 o'clock. The 18 kt white gold diamond-set President bracelet closes with a concealed folding Crownclasp, carrying the dial's theme throughout the entire piece.
Inside runs the Rolex Calibre 3255, a perpetual, mechanical, self-winding movement certified by COSC to a precision of -2/+2 seconds per day after casing. It provides a power reserve of approximately 70 hours via bidirectional self-winding through a Perpetual rotor, and features a paramagnetic blue Parachrom hairspring alongside Paraflex shock absorbers. Functions include instantaneous day and date displays in apertures with secure rapid-setting and stop-seconds for precise time adjustment. Production year: 2024.
