I had quite opposite experince with casio. If I want water proof (like swimming) watches, I would have to buy bulky and super expensive gshock with GPS and tons of useless festures.

$20 chinese smart watch are completely water sealed, tiny and simple to use. I can even remove wrist band, to make them even smaller. Only downside is battery life is only one week.
