I wouldn't buy a tag without a warranty. Every watch maker I've spoken to says they break down constantly. If you want something nice but not too expensive get a quartz Omega.
It's one of the most recognizable and well made watches in the world and was worn in 007 Skyfall.
Tag does very well with their externals and puts a lot of detail into them, but their internals are simply terrible having an order of magnitude less reliability than the competition.
