First post here.
I bought myself a Casio G-Shock GW7900B-1 on Ebay and just received it today. When I got it out of the package it was working fine and I was able to set the time correctly. An hour later I attempted to reset the time to military time (24 hours) and none of the buttons were working. It's still on time keeper mode however I can't access any of the different modes.
Has anyone had similar issues before and does anyone know of a quick fix. I really like this watch and before sending it back would like to know if their is a way I can fix it.
Thanks for the help.
