those are pretty expensive fake watches
i wouldn't judge on the pics on those sites, those are probably the real models you're seeing
they have the clockwork of a $5 kids watch, the cronograph (if any) doesn't work, the "gold" or "silver" irritates your skin
those that notice you're wearing an expensive watch often know enough about it to be able to tell it's a fake or not
what's the resale value of a fake watch ? hehe
