In a first for Zenith, the manufacture has cladded its 1/100th of a second chronograph in a green ceramic armour for the DEFY 21 Urban Jungle. Highly scratch-resistant and intensely coloured, the Urban Jungle’s khaki green ceramic case is finished entirely in a matte finish, flying under the radar while still standing out to its wearer.

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.
