Durable Watch with a good look
I like watches, and have bought quite a few over the years. I got this watch as something to wear in work. It is not bulky so you don't get bothered by it on your wrist ever. You can wear it with many different outfits and it works. I prefer watches with hands over pure digital so I really liked that aspect of this watch. Just a nice practical watch overall, does what its supposed to. Tells the time.

Learning curve to setup
Really nice watch, but you have to take the time to learn how the four buttons are used to set date, time, day of week, daylight saving, time zone etc. Watch the YouTube videos, download the user and operational guides from the Casio web site the teeny tiny manual in the box is almost unreadable. Once you’ve done all that it tells the time, I don’t really need the alarm or stopwatch functions ;-)

Instruction manual needs to be improved
Setting up of time not easy to follow in instruction manual -this needs to be reviewed. The dial and hands and digital time mode on the blue model is not easy to read . This is the third G shock I have purchased both have run out of batteries after about three years and to replace they recommend you take to Casio dealer. Have tried and failed to replace my self but not easy. Once sorted its a good watch.
