Watch O-rings are small seals used inside your watch to help maintain water resistance. Over time, they can dry out, flatten or crack, which may reduce the protection of your watch against moisture and dust.
Before ordering a replacement, it’s important to identify the correct size and type of O-ring for your watch case or component.
If you have a Casio, Seiko, or Citizen watch, we might be able to source a genuine part for you. Please click the links below to find out the information we require.
For any other watch, we can only supply round O-rings.
To identify the correct replacement, we need the following measurements:
- Profile diameter
- Internal diameter
- External diameter
For the most accurate results, we recommend carefully removing the existing O-ring and measuring it using a digital calliper. Even small variations in O-ring size can affect water resistance and fit, so accurate measurements are essential.
We can also help identify glass packing gaskets using the information provided above.
Our team will be happy to help identify the correct replacement O-ring before you place an order, however we do need all the information requested in order to assist. The more information you can provide, the faster and more accurately we can help find an O-ring that suits your watch.
