I'm with TVT here. I've had 3 Asian 7750 die within months. Sure, the can be serviced, but then I'm spending $600 for service on top of $600 for the watches. That $1200 buys me a very nice, albeit used, Omega Speedy, a SMP, a nice new Tag, an inexpensive Breitling. All of them work out of the box. And if they don't, someone backs them up, no questions asked for a couple of years.
Think of it this way...
You buy something that is brand new(car, guitar, bike are the three I'm familiar with. Pick something). In order to use said "new" thing reliably, you have to spend up to 2/3 of the original price of the thing on service. Think about it, a rep with an Asian 7750 costs about 300, to get it serviced another 150 to 200. You wouldn't spend that on your new car, new bike, new guitar...you name it. It seems foolish.
