About this watch

The Zenith Defy El Primero 21 Ultraviolet is more than just a watch; it’s a celebration of innovation, precision, and style.

This level of engineering sets Zenith apart in high-end horology. The power reserve for the chronograph is 50 minutes, and it can be wound by hand.

Investing in a Zenith watch is like investing in a piece of history, and the Defy El Primero 21 Ultraviolet is no exception.
