Zenith El Primero 1969
In the 1969 race to create the first automatic chronograph, only Zenith succeeded in designing a fully integrated movement. The El Primero internals are still some of the finest around, and have found their way into such classics as the Rolex Daytona. A 40th-anniversary edition of the original Zenith El Primero watch was released in 2009.
