High quality sloped ceramic bezel insert. Will fit the Seiko SKX007/SKX009 line of watches as well as the newer Seiko 5 Sports SRPD or "5KX" models, or any cases which share compatibility with the aforementioned watches.

Also work with some generic "Submariner" cases available commercially.


Available with or without an adhesive ring.


These inserts are sloped and work best with domed crystals, or flat crystals in a submariner type build. These SLOPED inserts DO NOT FIT with stock SKX or SRPD crystals. You MUST use a crystal designed for use with sloped ceramic inserts. I sell these as well!
