It would probably be some sort of Piezoelectric Buzzer I think.

Not too sure if they are easy to replace or not.

I believe its a Piezo, though I'm not entirely sure. It generally lives, at least it did on the couple of Casio watches I pulled apart, on the back cover ofthe watch. I think some of them have a tiny spring contact or similar that makes contact with the piezo.

You've probably lost the spring contact for the buzzer on the back of the watch. I do remember that part of the buzzer piece was insulated so that if you put the cover on upside down, the buzzer wouldn't work.

No idea on availability of spares or anything like that unfortunately.

any small spring should work. Even a strand of wire folded over a few times might do the trick.

battery just died..just my luck...i will take it to the shop and ask how much he is gonna charge me for the spring, if its more than 10 bucks i will try the spring in the watch belt pin and if that does not work i will try a piece of wire...
thanks...
