I have a Casio Pro Trek PRG-110CJ that I bought in Japan. They told me I could down load the English users manual, but I cannot fid it on their site. The number on the back of the casing is 3207. Any help would be much appreciated. If there isn't a manual for this exact model then one for a similar model will do. Thank you.

Try the links. Casio has two distributors for parts.

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!
