It was in 1969 that Zenith went down in history by launching the caliber named El Primero - meaning "the first" in Esperanto - that marked a watershed in contemporary watchmaking history. It was the first ever automatic integrated chronograph movement. Designed as an inseparable whole, it had no additional module but instead featured a construction built around a column wheel and a central rotor mounted on ball bearings. Better still, it beat at the high frequency of 10 vibrations per second, making it the world's most accurate series-produced chronograph to this very day. This chronograph featured also the historical colours of the first 1969 El Primero model.
