G-Shock lovers, now this might literally 'shock' some people here and it is not a pleasant topic to talk about, but I'm afraid to tell you that my newly acquired GB-5600B1JF has reset itself for several times and I know the reason why. It is not a problem with the battery.
In the beginning I was thinking it had something to do with the bluetooth connectivity to my iphone and that the loss thereof would probably somehow reset the watch. That was not the case.
In fact, this G-Shock fails because of electrostatic discharge. In other words: This G-Shock literally cannot stand shocks.
Now in these cold times I'm wearing woollen pullovers and other thick materials which in friction with other materials cause electrostatic charges that result in electric sparks.
I can reproduce the problem as following:
As soon as I pull off my jacket the display of the watch switches off for about half a second, all connectivity is lost and the watch is reset. This is kind of annyoing because you will have to adjust all settings anew in the iphone app.
Of course I have tried to reproduce the problem with other G-Shocks (some 5600s, Rangeman, King), but fortunately these would not fail in this process. My brother has told me that certain plastic materials (especially certain black ones - just as the black model of this 5600) conduct electricity better than others.
As the watch is more or less new, I would cancel out battery malfunction. I'm also writing this because in the last days I've read someone else's problem with his watch resetting itself without an observable reason. It was a 6900MS - also a black model. Maybe it's the same type of resin used therein.
I cannot return the watch as I imported it from Japan, and I really like it on the other hand. After all, it has the best visibility of any negative display I've seen on a G-Shock (except perhaps the gd350). Should I contact Casio? What would you do?
Thanks in advance
