Hello there!I hope that I posted in the right section and also the question wasn't asked before.Maybe it's not polite from me to ask about this,but how is the battery on the gwg 1000?From the Casio's specs it looks like 6 months is the battery life,and that gives me a reason to worry about because I have a GW-7900 and in specs it says 9 months battery life.I played a little with the EL screen and the watch reached the M level of battery.I was thinking:if so a simple watch like mine is discharging so fast,what will happen with the GWG-1000?I found out that both watches have the same CTL1616 battery.Is it worth buying or will I have problems with the battery?Thanks!
