Hello, helping a friend out with this one below, G-7300 module 2534.
It has "died" and you'll note the triangular indicator blinking in upper left. I'm guessing a battery replacement might do the trick?
I'm going to open it up and give it a good clean, but resin rot has set in, could be dangerous. This watch has seen some serious action. I've never seen such pock marks on a crystal.
