They’re pretty similar IIRC. Real ones are maybe a little firmer and less springy but they’re basically the same. The biggest difference is that the real ones are made to exactly the right length for your wrist size whereas the imitations are one size, so inevitably a bit on the long side.
It's the stretch I'm mainly concerned with, I have a fake one already and the watch bounces around a bit too much for my liking, especially if cycling with it on.
