  • I was sooo excited! The back was off..and there’s a plate..covering any sign of a battery ..I gently tried to pry it and the entire watch face came out..a small electrical disc and no obvious way to remove plate safely without whole watch coming out..I assume the battery is under it🤯 this is the 3rd and last time I buy a g-shock..casio used to be a good brand ,my boys deserve better..these are troublesome.
