Casio DB 360. The alarm was set accidentally. I cant sleep at night because the alarm keeps on beeping every after a few minutes.

Question edited for a little more clarity.

This is one of those watched with multiple dials and dozens of functions. It sounds like there is an hourly repeating alarm at 10 minutes to the hour. All time zones are synchronised to the top of the hour. The best thing to do is remove the batteries for 2 minutes and replace them. Then set the time again.

Hi as far as I know this watch model only beeps when you are configuring time and when you want to go back to time mode from any other one (chrono, world time or alarm mode) by pressing left lower buttom for a few seconds. It only beeps if you have set the alarm. It does not have light either. Hope this clarify.

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

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
