WOW, I see the sapphire version is 79.50 for the 1680. I guess it would be expensiv being the first Submariner with a date. I could look at this as a one time purchase. Plus the scratch free qualities.
Well, as you see in the pics I already did the scraping on crystal edge with the emory board fingernail file. I got the retaining bezel down real flat but I am missing the rubber gasket that is suppose to be in the groove so maybe thats why i see a micro gap. Manuel, maybe its good I did not use the file on the inner retaining bezel in case I get the sapphire conversion crystal it will grab easier and smoother.
