In terms of functionality, I see watch as fashion thing. So I normally see all of them as grossly overpriced. For $3,000 you can get a decent motorbike that can move you from one place to another 100 km away. You just look at it to know the time, almost nothing else. But that's how I see it.
I wear a $100 Guess with black straps, very classy looking and it works underwater up to 50 m depth. Overall I like it, and it was a birthday present from my brother.
