Presented in a 40 mm 18 kt white gold Oyster case, reference 228349RBR-0041 features a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown, offering water resistance to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with Cyclops lens magnifies the date window for effortless reading.
The slate dial is equipped with a Chromalight display delivering long-lasting blue luminescence, ensuring legibility across varied lighting conditions. Day and date are shown simultaneously through apertures with instantaneous, secure rapid-setting, and a stop-seconds function allows for precise time adjustment.
Power comes from the perpetual, mechanical, self-winding Calibre 3255 — a Manufacture Rolex movement certified as a Superlative Chronometer following both COSC testing and Rolex certification after casing. A paramagnetic blue Parachrom hairspring and Paraflex shock absorbers support the oscillator, while bidirectional winding via the Perpetual rotor provides approximately 70 hours of power reserve. The watch is completed by an 18 kt white gold President bracelet with semi-circular three-piece links and a concealed folding Crownclasp.
