Rolex Unworn Cosmograph Daytona, 126503

We are proud to present this exceptional Rolex Cosmograph Daytona for sale in unworn, fully checked and authenticated in our accredited workshop.

Originally launched in 1963, the Rolex Cosmograph Daytona has become one of the most iconic and sought-after chronographs ever produced. Designed as the ultimate timing instrument for endurance racing drivers, the Daytona is instantly recognisable by its tachymetric scale, three chronograph counters, and screw-down pushers. It has transcended its origins in motor sport to become one of the defining references in modern watchmaking, combining exceptional performance with unmistakable Rolex design.

This example, reference 126503, is presented in the classic 40mm Oyster case crafted in Yellow Rolesor, the harmonious combination of Oystersteel and 18 ct yellow gold. The middle case is fitted with a screw-down case back and winding crown, while the fixed 18 ct yellow gold bezel features an engraved tachymetric scale for measuring average speeds of up to 400 units per hour. The striking white dial is distinguished by contrasting chronograph counter rings and 18 ct gold appliqué hour markers and hands with a Chromalight display, providing exceptional legibility in all lighting conditions. At its heart beats the Rolex calibre 4131, a self-winding mechanical chronograph movement delivering approximately 72 hours of power reserve and certified as a Superlative Chronometer for outstanding precision and reliability. The watch is completed by the solid Oyster bracelet, securing the case with the robust and unmistakable comfort of Rolex's signature sports bracelet.

Originally purchased in May 2026 and presented in unworn, this watch is supplied complete with its original inner and outer presentation boxes, original swing tags, Rolex informational booklets, and international warranty card. It remains covered by the official Rolex International Warranty until May 2031.
