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!

It is often written in tiny engraving. The jeweler will know.

Hi,

The backplate is a "pry open" back. so you will need something like a blade or a hard thin flat object to pry the backplate. once this is done you will have access to the battery. Please note that there is a tiny Philips screw that holds the battery plate. you will have to remove this screw and then remove the battery plate. Also, note that around the case there will be a thin rubber "o" ring. this is what makes the watch water-resistant. so pls male sure you fix it back when you reinstall the watch.

If it is indeed a screw type back it will have indentions ON the back (6 to 8). A special tool is required to remove the back without damage to the watch back. Any reputable jewelry store should be able to remove the back. If there are no indentions then it should be a pop back. Some watches do not have a slot to slide a pry tool under the back. You have to use a sharp knife..taking appropriate safety precautions.

I also show how to polish the metal portions of your watch. ... of how not to take the back off and remove ...Missing: irish

TGXL103GRN Check inside watch where the battery holding area has a metal tab to secure it. There's always a big gap btwn the tab/batt area and where it makes keyboard contact. To fix:
1 remove screws and watch back.
2 put tiny screws in dish
3 notice battery condition/position.
4 change batt if necessary
5 fold a tiny piece of paper to fill gap
6 use tweezer to put in place (no foil, no glue)
7 to test if gap is gone, close watch
8 must screw shut + reset to test
9 be patient, adjust as needed
10 take care to not strip screws.

It's not as easy as popping off the back like some watches to replace the battery. The 4 screws on the top bezel are not the ones to remove. Look at the back side of the watch and you'll see 4 really tiny pinholes. You'll need a jewelers screwdriver small enough to fit into the holes to remove the 4 screws. Once you do that, the two halves of the watch come apart with a little pressure. It takes a little prying to get the case to separate. Once you do that, you'll see the battery. Be careful with the waterproof gasket as you'll need to put that back in the same position to keep the case sealed. The gasket is really delicate. You might consider taking it to a watch maker to change out the battery if you don't have the tiny (and I mean really tiny) screwdriver to remove the 4 back screws.

Welcome to Fixya,

Hi hope this steps will helped you in changing the battery but I just want you to remind that you have to be careful in changing the battery because it might affect the other part.


1- remove the crown by pulling away from the watch, use your thumb and index fingernail and pull , it will come out

2- remove all 5 gold bezel screws

3 - be careful,, the bezel/crystal will pry off easy

4 - be careful and remove the entire face/hands/watch guts all in one easy step,, or just turn the watch over and it will fall out

5 - small screwdriver and remove/replace battery

6 - reinstall watch guts/bezel and gold screws

7 - push crown back into watch

Thank you for using Fixya.
