Why does my Casio 2628 watch keep resetting itself every (night) to daylight savings time when it isn't daylight savings time?

just reset the time as if the watch stopped
daylight time is not a special time just an hour earlier or later

Today my 6-year old Waveceptor has adjusted itself to daylight Savings time without my intervention. I was agreeably surprised. For all the years I have had the watch, I kept the module manual by my side just for the two times a year I have to adjust the time.
All this to tell you that you imperatively have to read the module's manual. If you do not have it visit the Casio Worldwide web site and download it. You need the module number. You will find it on the back of the watch. It is a 4-digit number inside a rectangle.

Perhaps it has changed to daylight saving time if you accidentally pressed the mode button. Were you wearing the watch?

It looks like daylight saving time (DST). You can reset your watch to turn it off.

If you haven't go any instructions on how to do this, you can get instructions from the Casio web site.
