Rolex Daytona 16520

ROLEX Cosmograph Daytona 16520 white WATCH 705840

The Cosmograph Daytona is the first Mechanical Automatic Chronograph to be created by revising more than half of the parts of the Zenith El Primero. It has been 56 years since the world's first mechanical automatic mechanism with a fully rotating rotor was announced in 1931, which shows how difficult it was to achieve the practical performance required by Rolex. It should also be noted that this generation supported Rolex's rapid growth from the late 1980s onwards and became the origin of the subsequent Daytona myth.
