This page describes how you can change watch batteries and straps yourself.
Summary
Most watch batteries are easy to replace. This guide is for watches with a snap fit back and not a screw-on back. (That will be added later. A snap fit back is the commonest type.
Safety
- 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.
Tools
You can get a tool kit quite cheaply from eBay and other sites containing most of the basic tools you'll need, and you can supplement this as required. They will pay for themselves with the savings from changing just a few watch batteries
Here are some general tools you may find useful. (More specialised tools are listed in the relevant sections below.)
- Error creating thumbnail: File missing
A dust puffer - may be useful for expelling dust if it gets into a watch.
- Error creating thumbnail: File missing
A set of precision screwdrivers or a selection of flat and cross-head jeweller's screwdrivers is likely to be needed.
- Error creating thumbnail: File missing
A watch holder will sometimes be useful for holding a watch steady.
- Error creating thumbnail: File missing
A magnetiser (or any neodynium magnet you might happen to have) for magnetising screws, making them much easier to manipulate.
- Error creating thumbnail: File missing
Straight and angled tweezers may be useful. (If used for watch batteries, always hold them across a diameter, not across the flats.)

Removing and replacing watch backs
Snap-on watch backs
Tools and consumables
The following inexpensive special tools will be needed:
| A case-opening knife or a flat screwdriver with a thin blade is required to remove the back. | |
| A watch press (shown here with a watch in place) with a relection of dies is essential for replacing the back. | |
| A nylon mallet may be useful for removing a reluctant watch back. (N.B. DO NOT use this for attempting to replace the back.) |
In addition, the following general tools:
- A bright light or a head torch.
- If you use reading glasses, you will need to use them. A magnifying glass or jeweller's eye loupe is helpful.
See Magnifiers and Inspection Aids.
Consumables:
- A replacement battery. Ideally you should use the internet to find out the battery that fits your watch. There are many different types of watch battery and they can be bought at a good hardware store, or Amazon or eBay. Of course if you cannot find out which battery is required, you can open the watch and see the battery that is in place.
- 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.
| 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 or watch case opening knife into the gap in the lift-off area. Twist and the back should pop off. In difficult cases, it may help to tap the end of the screwdriver with a nylon mallet. | |
| 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. |
Replacing the back
Your watch press should come with a selection of dies that screw into place. You need to select the underside die that supports/contacts the metal case only. Too small means that the edge of the die is pressing on the glass. Too big means that the main part of the die is in contact with the glass and the outer ring is not on the metal case. The choice is crucial to avoiding damage to the glass.
- Error creating thumbnail: File missing
Ideal placement with die in contact with watch case only.
- Error creating thumbnail: File missing
Die is too small and only in contact with the watch face.
- Error creating thumbnail: File missing
Die is too big and pressing on the watch face.
The upper die will press on the watch back to snap into place. The die has to be at least as wide as the watch back, but the choice is less critical.
One the dies have been screwed onto the pegs of the watch press, carefully place the watch onto the lower die. The put the back onto the watch making sure that the cut-out for the winder shaft is over the shaft. Make sure the back is aligned evenly and is not tilted.
| Gently squeeze the handles together so that the upper die contacts the back and check that it is even. Then increase the force of your squeeze and you should hear/feel a snap as the back goes into place. |
Screw-on watch backs
Tools
| A 3-point watch back remover is essential. Watch repair kits often come with a 2-point tool. You can use this, but you will find the 3-point version more stable and easier to use, and well worth the modest extra cost. |
Removing the back
This type of watch back typically has 6 indentations around its circumference. This is easily removed with a 3-point watch back removal tool. It may come with several sets of points which can be adjusted to precisely fit the indentations in the watch back. Gently but firmly twist the back anticlockwise in order to remove it.
To replace the back, make sure it's correctly placed. If you twist it anticlockwise with your fingers you should feel a slight click as the thread engages. Now turn it clockwise, first with your fingers and then with the tool.
Screwed-on watch backs
Sometimes, you might come across a watch with the back secured with screws. Take care to use a jeweller's or precision screwdriver of an appropriate size and be careful not to let it slip as you may damage the screw heads, making them harder to remove in future. Place the screws in some kind of receptacle such as a lid, so as not to loose them.
The very simplest case is where the battery compartment cover has a slot, enabling it to be opened with a coin. Twist it anticlockwise through around a quarter turn or less and the cover will come off.

Replacing watch glasses
A watch with a broken, cracked or scratched glass can be repaired. At a jeweller's this might be quite expensive but you may find that you can do it yourself for less, including the cost of a special tool and replacement glass. Search online for detailed instructions.
If the glass is still intact, a grabber will allow you to remove the damaged glass and also to compress the replacement glass in order to fit it into the watch shell, in which it should be a very tight fit. Sets are available containing a wide range of replacement watch glasses, though only circular. Other shapes will probably only be available from the watch manufacturer, if at all.
