Watch Gasket Plastic "I" Gaskets

These I watch crystal gaskets are great for watchmakers and others who work on watches and replace watch crystals. These round gaskets are made of nylon-plastic to create an airtight seal that prevents water from entering the watch case and to hold the crystal gently and firmly. The nylon-plastic gasket will compress and use friction to hold the crystal in place. As this assortment includes gaskets of various sizes, you should definitely be able to find a correct match for the gasket you need to replace. These I gaskets are sold individually; simply select the size you need from the drop down menu above.
