Hi, I'm new to the whole G-Shock thing and have some questions about the gw9000 mudman. I've never been a digital watch fan, but these are very cool! My question is, how lond dothey last? do the bands wear out quickly, or last a long time? How good is casio's customer service if I have a problem? I'm alittle nervous about spending around 100USD for a digital watch unless it will last a long time.
