Sorry, not really G-shock related but I've been digging out some of my old watches this evening and have counted 7 quartz watches that have dead batteries in them. One only went a couple of weeks ago, but the others have been dead for anything between 5-20 years.
The oldest, a Casio J-51W has a big black mark where the liquid has bleed onto the face, so I guess this watch is dead.
My main questions though are:-
A) I would like to get some new batteries fitted to some of them (mainly 3 old Casio running watches), but as they have had dead batteries in them for so long, could that have damaged the watches?
B) Is it worth removing the dead batteries from the other watches that I don't want to put new batteries in?
