I'm interested to get you guys take on this. In my particular case, I've been eyeing an Omega Aqua Tera, but there's no reason to limit to that particular watch. Looking at grey market prices for that piece, it appears that discounts from 15 to 25% can be had for an unworn example of the currently produced model. I suspect that may get even better if the economy continues to go in the direction it seems to be going. As best as I can tell, that discount comes at a price of potentially a bit more stressful buying experience and the lack of a factory warranty. So the stress part aside, what is a factory warranty worth to you? At what point do you click buy? 25% is a big chunk of change for something like an Omega, which seems to be a very stable and reliable watch. The likelihood of needing to service it under warranty seems relatively low. I realize it's always a gamble, but is there a number that would make you take the plunge? At what point do you say sure, I'd miss the glass of champaign at the fancy AD, but this is worth it?
