Unfortunately, that is a complex watch that I am going to have to send you to the Casio help/support for. Here is a link for you:

Sorry could not help more. Jewel

mcdevito75 here, This can be very, very tricky on a Casio watch, Casio"s have an LCD liquid crystal Diode in the face and any un-do pressure on the face will break it. Best Bet, look for a small watch repair shop in your area to change the battery, a small shop will save you some money on the cost.

Click on my profile (escapement), then click on Tips and Tricks. There you will find link to all Casio watch manuals. Rate me, plz.

how do I reset a Casio lap memory 50 or 60 watch

This may have a reset button inside the back , maybe marked a.c. if it does you need to short it with metal tweezers between the battery and the a.c. button.
hope this helps
