Question
How do I change the battery in the subject watch?  It takes a  364 battery but I can't open the back to change it.  Is there something I need to know?

Answer
Hello Jack,

I know I am in clock and watches but I only work on clocks.  Not sure if your watch has a screw on back or a very small tab to pry open but usually has one of the two.  If it is a screw type it is best to use a piece of rubber or thin foam to turn it to the left.  Look for a very thin rubber washer that will have to be replaced.  

If it is a snap back it might have a tiny lip on the outer part of the back and if not looking under a magnifier see if there is a slight slot between the back and the case.

Hope one of these work.

Also it it has a Rolex style screw off back with 3 notches on the outer part of the back it will need to be opened with a Rolex tool as it is a screw on also.

Good luck and do no harm.
Harold
