Introducing the Zenith Defy El Primero 21 Urban Jungle

Zenith expands the avant-garde Defy collection with the introduction of the Defy El Primero 21 Urban Jungle for LVMH Digital Watch Week 2021. In this new version, the world's fastest chronograph in production features a khaki green case, an El Primero 9004 movement with green base plates, and a green rubber strap with Cordura pattern. The result is a striking new look; under the radar, while standing out to its wearer. Arguably the perfect watch to navigate today's urban jungle indeed!

The khaki green ceramic case of the El Primero 21 Urban Jungle measures 44mm across. Inside ticks Zenith's El Primero 9004 movement. 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 9004 a category of its own. The central seconds hand makes one rotation every second - a sight to behold. For the Urban Jungle its base plates are finished to match the khaki green case and strap.

The Zenith Defy 21 Urban Jungle is available for pre-order in our eBoutique.
