Zenith once again reinvents the chronograph with its 1/100th of a second automatic chronograph movement, raising the bar of precision to unprecedented heights. Specially treated in a Zenith Blue tone, the 1/100th of a second chronograph movement visible through the open dial contrasts beautifully against the black ceramic case.

A high-frequency revolution. The El Primero 21 is the culmination of over 50 years of perfecting the automatic chronograph at the Zenith manufacture. Equipped with two regulating organs and escapements, one beating at 5Hz for timekeeping, and the other at an incredible 50Hz to offer a true 1/100th of a second chronograph display, the El Primero 21 is the chronograph calibre of the 21st century.
