Summary

Most watch batteries are easy to replace. This guide is for watches with a snap fit back and not a screw-on back. A snap fit back is the commonest type.

Safe

To do this task you need a watch press otherwise you will either be unable to replace the back, or you might break the glass

Do dispose of the old battery properly. Keep batteries out of the way of children as they can be fatal if swallowed.

Main section

Equipment

For a snap fit back you need a watch press. They are not expensive and can be bought on eBay or Amazon.

Watch maker's screwdriver. You need a flat ended screw driver with a fine end to prise off the back

Battery. Ideally you should use the internet to find out the battery that fits your watch. There are many different types of watch battery

A watch press with a watch in place face down

and they can be bought at a good hardware store, or Amazon or eBay. Of course if you cannot find out that battery that is required, you can open the watch and see the battery that is in place.

A bright light or a head torch

If you use reading glasses, you will need to use them. Magnifying glasses are helpful

Isopropyl alcohol and tissues

Removing the back

Clean the back of the watch with isopropyl alcohol giving particular attention to the join between the back and the body of the watch.

Lift off area on the watch back

Examine the edge of the back piece to find the small raised area where you will insert your screwdriver.Make a note or take a photograph of the back. Note the position of the winder when the writing is the right way up.

Carefully insert the screwdriver into the gap in the lift off area.

The lift off area is bottom left on this watch, but it is not always in this position

Watch back showing O ring and also the notch for winder.

Twist and the back should pop off.

Examine the back. Look at the O ring and check it is undamaged. Identify the notch on the back for the winder. You will need to orientate the back so that the notch is over the winder when you re-assemble the watch.

You can see the battery and the spindle for the winder.

You should now see the inside of your watch. If you do not know what battery is needed, you can see the number on the old battery. In the photograph the battery number is 364. Renata is the make, but there are many other makes of battery.

Removing the battery. Needle is for illustration only

If you have the replacement battery, you can remove the old battery. The battery is held by retaining clips on edge of the battery. Sometimes it helps to use a sewing needle to push the battery out, starting from the outer edge.

Watch with battery removed

Here you can see the watch after the battery has been removed.

You can now insert the new battery with the writing on the top as it was with the old battery. It should not require force to get the battery back in position.
