  • Loved this video. I recently changed the crystal (glass) in my Citizen watch. It uses a gasket, but I reused the old gasket. Now I know to order some gaskets and replace it with a new one. I will be removing and replacing the crystal again with a new gasket. Thanks again for such an informative video on such a basic topic. Greatly appreciated.

      The gaskets tend to get brittle with age and can sometimes develop hairline cracks.
      The end result of this would be water or moisture ingress which, of course, is bad!
