FAQs
Are these O-rings suitable for deep-sea diving watches?
These are designed for standard clock and watch maintenance. They may not meet the high-pressure specifications required for professional diving watches.
Do I need to lubricate these seals?
Yes, a light application of high-quality silicone grease is recommended to keep the rubber supple and ensure a better seal.
Can I use these for other electronics?
These are sized specifically for watches and clocks; they may not be suitable for other mechanical or electronic applications.
What material are these rings made of?
They are made from durable synthetic rubber optimized for flexibility and longevity in precision instruments.
How do I know which size to pick?
Use a digital caliper to measure the groove diameter of your watch case and compare it to the rings in the kit.
Troubleshooting
Seal does not fit the case back groove
Verify the diameter using digital calipers; ensure the groove is entirely free of old gasket residue or debris.
Case back is difficult to close after seal installation
The seal may be slightly too thick. Ensure you have selected the thinnest profile possible that still maintains a snug, secure fit.

Setup, Compatibility & Care
To ensure the longevity of your seals, keep the storage container in a cool, dry place away from direct sunlight, as UV exposure can break down the rubber over time. When selecting a seal, ensure it is neither too large—which may result in a bulging or pinched seal—nor too small, which will fail to create a proper barrier. Periodically inspect your seals during annual maintenance checks; if you notice any cracking, dryness, or flattening, replace them immediately to avoid movement damage. Always use silicone grease sparingly, as excessive lubrication can attract dirt and lint.
