The Rolex Cosmograph Daytona Ref. 126503 is one of the most refined and contemporary versions of the legendary sports chronograph by Rolex. Designed for speed and precision, this model blends cutting-edge engineering with timeless sophistication and luxury.
The 40 mm Oystersteel and yellow gold case combines strength with elegance, featuring polished and satin-brushed finishes that highlight its distinctive character. The fixed yellow gold bezel with engraved tachymeter scale reinforces the Daytona’s heritage as a precision instrument built for the racetrack.
The white dial with gold subdials ensures excellent readability and aesthetic balance. The gold hands and hour markers with Chromalight provide optimal visibility in all lighting conditions.
Powered by the Rolex Calibre 4131, an in-house self-winding chronometer movement, the watch offers hours, minutes, small seconds, and chronograph functions with a power reserve of approximately 72 hours. The movement features Rolex’s Chronergy escapement and Parachrom hairspring for superior resistance to shocks and magnetic fields.
The two-tone Oyster bracelet in steel and yellow gold, with solid links and Oysterlock folding clasp featuring the Easylink extension system, ensures both comfort and security.
