Product Story

The Cosmograph Daytona was originally created as the ultimate timing tool for professional racing drivers. Featuring a tachymetric scale, triple sub-dials, and responsive pushers, it quickly gained legendary status both on and off the track. Rolex registered “Yellow Rolesor” — the fusion of gold and steel — in 1933, a hallmark of strength and elegance that remains central to the brand’s identity today.

The Ref. 126503-0003 showcases the evolution of Daytona design, combining its recognizable silhouette with modern upgrades and a luxurious two-tone appearance. While the authentic model features Rolex’s calibre 4131, this version utilizes a robust Miyota automatic movement to ensure everyday reliability. The Oyster bracelet, first introduced in the late 1930s, enhances comfort and durability, making the watch suitable for both sport and formal wear.
