New old stock never opened tropic 17 Rolex watch crystal.

This is not a service crystal, this is a genuine tropic 17 Crystal from the 70s.

This Crystal will have the right profile for the period of you watch.

You'll notice on service crystals there is more of an edge. I have taken a photo of every side of the Crystal packaging as to ensure you that it has not been opened. 

To be very clear the catalog in the background is not included in the auction
