Again love GShock
This is a very Beautiful watch I had to buy it. It was very simple to setup comfortable if you like Casio watches. I highly recommend but note that the screen on this watch is very small that displays the digital time but the light is very bright enough to see it clearly.

I am a man and I wear this watch and love it
Sometimes the hands can be a little bit difficult to read but I've gotten several compliments from people on this watch and I'm not a small guy So even though this isn't as large as the man's g shock watch faces it still looks good on my arm and I like it a lot and wear it almost daily

Perfect for men too

buttons too depressed
maybe it is just what we got but the buttons are almost impossible to set. Needed twice a year. Added star as the other we bought just failed making this a winner. So I am missing a better button handling and some automatic time (I sometimes have to sync the hands )
