Interestingly, Rolex equipped the first automatic Daytona with the Zenith El Primero.Īt the time of writing, the Chronomaster Sport collection consisted of five models, all of which are powered by the in-house caliber El Primero 3600. There are vast differences between the two, namely size and color scheme, subdials, shape of the indices, and the bezel markers. However, a side-by-side of these two models reveals that they really only seem similar at first glance. It didn't take long for watch enthusiasts to draw parallels between the Zenith Chronomaster Sport and the current generation of the Rolex Daytona. You can recognize this movement by the arrangement of different colored subdials at 3, 6, and 9 o'clock and the date window at 4:30. Together with the Heuer 11 and Seiko 6139 calibers, it is considered to be one of the world's first automatic chronographs. Zenith's first version of this movement, the A386, was first launched in 1969. The El Primero 3600 is a high-frequency caliber its balance oscillates at 36,000 vibrations per hour. With the help of the markings on the bezel scale, you can read the elapsed time with extreme precision. This hand sweeps around the dial in just 10 seconds after the push-piece is pressed, rather than the usual 60. This movement's distinguishing feature is its ability to measure times to 1/10th of a second thanks to the central second hand. The sporty chronograph uses the in-house caliber El Primero 3600, a further development of the El Primero 400. Only 50 copies were produced of each model in the trio.

The Chronomaster Sport is a series-produced model coming on the heels of the anniversary trilogy of the Chronomaster 2 El Primero, El Primero A386 Revival, and the Defy El Primero 21. Zenith released the Chronomaster Sport to mark the occasion of the 50th anniversary of the El Primero caliber, albeit with a two-year delay, in 2021.
