The model number of the battery in your watch will be marked on the battery itself. If your watch does not have a battery inside and you need to know the model number, please contact Customer Care with the style number of your watch (located on the back of the watch, e.g. ES1234 or FTW1234).
We don't recommend trying to change the battery yourself, as the internal movement can be damaged in this process.
We advise taking the watch into a local Fossil store or sending it to our service center to have the battery replaced. To check for a Fossil store near you, click here. Battery types and availability may vary by store. We recommend calling ahead to ensure the battery for your watch is in stock.
If you don’t have a Fossil store near you, you can submit a repair request to have the battery changed at our service center. Click here to get started online.
You may also take your watch into a local reputable jeweler to see if they can change the battery. However, if the watch’s movement is damaged or the watch becomes water damaged because of seal problems, the warranty may become void.
