I didn't mean to imply you aren't a watch enthusiast because you like the Big Bang.
I agree that most sport watches below 40mm is considered small, these days, for better or worse, but there are zillions of current non-dive or non-chrono watches that are 40mm and smaller.
Plus, as I mentioned earlier, cause diameter can be misleading. The Moto 360's bezel is so thin that the watch seems to wear much larger than a 46mm diver with a thick bezel.
But the curious thing is that although I like the big bang I don't buy one, simply because it's too big for me, a proportion thing as I said. When talking about my personal choices I also buy smaller watches, because I don't care if they advertise bigger watches as the trend if they look ridiculous on me. The same thing happens with the galaxy note/iphone 5,5 or whatever gigantic smartphone, it does not matter how much they advertise them and how many features they have because I will never buy that kind of size if I have a choice, it does not matter if it's worse when it comes to specs.
