Casio watch displays "open" on screen

The solar watch that you have is broken then.

You can download the manual from the link below. The timekeeping instructions are found on pages E-19 - E-24

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.

it's because the contact that sense whether the watch is opened or not is misaligned.
Just open the watch caseback, re-allign the gold contact on the case-back, and make sure it touches the spring in the other side of the watch.

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!

Because it is not a documented problem for this watch in the user manual to be found at http://ftp.casio.co.jp/pub/world_manual/wat/en/qw2767.pdf

Are you sure you acctually have a Casio Protrek Tough Solar Ana-Digi PRG-60T unit or do you perhaps have some other model of Casio watch and have posted in the wrong place on the forum?

no, it changed automatically via the atomic satellite that changes all atomic clocks around the world. It so happens you bought a watch that was made in a different, much different time zone. You have been taken.

Your Watch is in Auto or demo mode. Hold down the "Mode" button for 3 - 5 seconds and it will return to time keeping mode.
