In every watch, there are several gaskets: a back gasket, a crystal gasket, a bezel gasket, and a crown gasket to name just a few. These watch gaskets are made of specialty rubber or neoprene, and sometimes from plastic for crystals. Watches have gaskets because they protect your watch from things like dust, water, perfume, oils, dirt, and other residues that wristwatches and pocket watches are exposed to. By protecting your watch’s precision mechanical and electrical components from moisture and dirt with gaskets you will dramatically increase the life expectancy of your watch. Even these amazing watch parts don’t last forever and will need to be replaced at some point, however, your watch gaskets will last longer and have better dust and water repelling ability if you apply a silicone or light watch oil to the gasket before placing it in the watch.
