I have read the tutorials about reversing the polarizing film to make a watch a negative display. I recently bought the GW-7900B, which is negative display to begin with. I plan on changing it to positive display using new polarizing film. But I have a few concerns/questions:

1) The watch is solar, and I fear that opening it and taking it apart may damage the connection of the solar panel or somehow turn the watch off.

2) Since there is a solar panel, is it glued on to the watch or something like that?

So if anyone has reversed the display on this watch, or any other solar atomic watches, I would like to know what they look like on the inside. I don't wanna open this watch and mess something up, and I am an amateur at tinkering with G-shocks.

Thank you for the help
