Have the same problem, Casio PRG-80L reads open. No hints about this in the manual. Nor did Votit's suggestion help. Note that although the watch is old there is clearly power left in the capacitor battery. Ended up accidently ito this mode when resetting the time. Assume the open mode is intended for service, but would just like to exit.
The problems is very simple: On the back cover (inside) is a little Cu metal Part. This part is glued to back cover using a poor glue (rubbered glue) and, in time, is moving from original position. You must put back this parts to original positin ( a little hole inside of back cover) and glue using a good glue. When the back cover is mounted , this part must have a ferm contact with two springs from mechanism (sensor for back cover open).
If beatwin this springs isn't a electric short (using Cu metal parts) the internal mechanism of watch "see" the back cover is open and show "OPEN" on screen!
Sounds like the solar back up cell needs to be replaced. You can get it repaired for rather cheap less that $30(US). You can contact www.casiosalesandservice.com to have it serviced. 877.659.0761
