Remember, if you have a particularly expensive watch or a waterproof watch that needs re-sealing then you may need to take the watch into the store to have the battery replaced. Many high end brands will offer a replacement service; this can save you damaging the watch by trying to replace the battery yourself. However, for your everyday watches, it’s a simple process to change the battery at home!

Replacing your watch battery

Your watch battery is likely to last for a long time, but inevitably the day is going to come when it gives out. When this happens, there are a few steps to follow to get your watch back up and running. First of all, you should test your watch battery when it appears to have stopped working; especially if your watch is quite old. This can ensure that it is actually the battery running out, and there’s nothing wrong with the watch itself. However if you don’t have a battery tester, often the cheapest way to find if it is the battery that has run out is to give a new battery a try.

Finding the right replacement watch battery

Once you’ve noticed that the battery needs replacing, make a note of the code or set of numbers on the original battery. This will help you find the right replacement battery. To understand the type of battery you need to be looking for, check the following battery prefixes:
  • SR = if the battery starts with this then the battery is a silver oxide battery, these are the most common type of watch batteries.
  • SG = is also Silver Oxide
  • L = Alkaline
  • LR = Alkaline
  • AG = Alkaline
  • CR = Lithium
  • 3-Digit numbers starting with a 3 eg; 377, 364. This numbering system is also very popular and these tend to be silver oxide watch batteries, they are better than their alkaline versions.
  • 3-Digit numbers starting with a 1 eg: 192, 189. These batteries are alkaline batteries. You can upgrade a 192 to a 392 if you prefer a better silver oxide battery.
  Luckily for you, within our range of watch batteries we have included as many cross references as possible for each battery to make it easier for you. The different numbering systems on watch batteries can make it very confusing to find the right watch battery. Once you understand the system a bit more, it can be easier to look for a replacement.

Opening your watch case

When it comes to replacing the battery, take care when opening your watch as it can be incredibly easy to scratch or damage it. Many watches will have a small indentation, created to help you remove the back case. Other models will require the removal of small screws before you can take the case off, please check it is safe before you take the watch apart! So, next time your watch battery runs out, don’t leave it to collect dust in a forgotten drawer! Get in touch with us if you need any more information.
