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

My Large Pilot Automatic from MassDrop came with a stainless steel case back. The sapphire display back was a nice addition to the watch, I just wish the sapphire case back came with the plastic spacer that the display back production watches got as the movement in the Large Pilot is quite small for the case.
Really nice to be able to see the workings of the watch. Would definitely recommend.
Sapphire crown, sapphire back! Really nice. Looks great on the back of my large Pilot watch. Seeing the watch movement at work is a real treat. Very nice.
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.
This product was exactly as described. The price was fair and the shipping was fast.
