The clear sapphire backs are the perfect way to bring new life to our classic retired watches from years past.
We have very limited parts available for these retired watches so get a spare sapphire back while you can. Some of these watches didn't ship with a sapphire back so this would be a great upgrade too.
All backs are made from both 316L Stainless Steel + Sapphire.
Make sure your ordering for the correct watch beforehand

When I noticed these were made available on their own I ordered right away. I have an older large Maratac Pilot (the ones without the triangle at 12) and the open case back was never an option then. If you are familiar with watches at all and have the right tools it is easy to change it out yourself. I have a case wrench, friction ball, and grease for gaskets. I also ordered a spare crown/stem just to have on hand in case anything ever happens.
I bought a Large Pilot many years ago before they were produced with a sapphire back. This was a really nice upgrade to an already awesome watch
It is to be able to have the Clear Sapphire Back on my Maratac watch to see the movement working...
