These watches were a complete 180 following some beloved Zeniths of the 1990s, like the Chronomaster Triple Date, the De Luca and the Rainbow. With time to reflect though, it was a huge culture moment for Zenith. Remember the pictures of Thierry Nataf with the falcon? I sure do.
To be honest, when it came out, I liked the Open version of the Defy Xtreme. The multilevel dial is interesting. The sub-dial registers are interesting. The heft of the watch is a nice feature. The build quality looks great. 1000 m water resistance is complete overkill.
The details of the watch really make it a conversation piece. The details of the watch make it a controversial piece. If you remove the very unserious text, the illegible sub-registers and the oodles of wasted space, you're left with a watch that isn't as interesting.
Is today's Defy Extreme a better watch? In my opinion, it sure is. Which watch will you reminisce about another twenty years from now? The original Defy Xtreme, of course. The Zero-G was a fascinating watch in the line as well and one of the most interesting watches of the era. IMHO the Defy Xtreme Tourbillon deserves special mention is THE icon of the mid-2000's oversized watch craze. It is a 1000 m dive watch with a tourbillon. It has the so-bad-it's-good date window and, in 2013, an amateur writing community that spontaneously formed on Amazon to submit some entertaining reviews.
