The 21 is absolutely a fast chronograph.
Zenith is showing power.
I look at some sources when Foversta shows us here the Zenith Defy 21 chronographs.
Interesting that your favorite color is violet.
Mine is dark green, or better said Rolex green.
The black and white UN Freak from Michael is also a peace that i like to see, or an AP RO off shore black and white.
Knowing Zenith have a Defy21 in black and white, it is my favorite.
