I got this for my 25th birthday. This is the first non mechanical watch I ever gotten (if not counting Apple watch which I used to wear in my right wrist) and I wanted simple utility watch that would be super accurate.
This has band 6 technology which takes time from radio signals. It updates the time daily which assures that the time is very accurate. It has the other basic functionality Casio watches typically has like sun charging.
The battery is supposed to last 10 years so I think it’s cool idea that I can wear this for 10 years and then need to get the batter changed when I turn 35. I have used this daily for almost a year now and I believe to use this a lot but probably not this much so it might last much longer than 10 years.
