What a nice idea. You're right about the Zenith Defy, shocking! I assume that when you say 'worst' you mean worst from the brands of which we expect more, because otherwise I could go all day!
Either way,
1. Zenith Defy, no question!
2. That Azimuth Lambourghini thing, close second!
3. Anything by Jacob&Co.
4. Panerai Egiziano, I know it's true to the original, but 60mm is ridiculous.
5. Rolex Leopard, it has to be in the top 5.
This is based soley on the final product, any motivations/agendas are not taken into account. If other factors were included, then Panerai and Cartier should get a dishonourable mention for being outrageously over-priced in most cases.
Apologies to anyone who owns/likes any of the above
