Tip & How-To about Watches

Changing Watch Batteries
Lots of posters ask "what is the battery in my (name of watch)" with a view to changing it yourself. This is a bad idea for many reasons. You don't have the tools or knowledge to remove a rotary screw on back, or the gasket sealant for a waterproof watch. Some fashion watches have 4 traditional screw and need professional grade jeweler screwdrivers. Also, there are about 20 batteries commonly used in watches, in various sizes and internal technology, Lithium Ion, Silver Oxide and Manganese Alkaline. If you buy them, you generally have to buy 10!

Don't sweat the details. Just take the watch to your local jeweler. They have all the batteries at hand and the tools to remove the back. It is done whilst you wait for $8 to $15!

mcdevito75 here, While a battery change is fairly easy, you will need a set of precision screwdrivers, you can improvise but could ruin your watch, Look for a small watch repair shop in your area the $15.00 will equal your time, effort, and tools you"d need. Plus the battery lasts a year.

It is possible the battery was weak to begin with, have the battery replaced to see if that will cure the problem because this a much cheaper way than the alternative.

I would return it sounds not like a batt. problem but internal mechanical. If you have a reciept dont deal with a potential problem get a replacement.
