ravishingrick Posted July 22, 2006 Report Share Posted July 22, 2006 Today I took my davidsen crystal to my watch smith to have it installed (PAM111h). When I picked it up I saw directly there where scratches on the crystal, but he said it was just dirty and needed to be cleaned. After cleaning the crystal, it was more then clear that it was not dirty but scratched serverly. He denied having any thing to do with the scratches. The crystal is sapphire so I doubt that the crystal itself is scratched, I think the A.R. layer must have been scratched out of the box or during installation. Questions: He said that he never came near to the back of the crystal, he said that the crystal is pressed from front downwards and there is no contact what so ever with sharp objects and the back of the crystal -> is this true? Has anyone recieved a davidsen crystal with scrathes out of the box? Is there a way to remove scratches from the A.R. coating, or remove the A.R. coating all together?

cwai02 Posted July 22, 2006 Report Share Posted July 22, 2006 no way to remove scratch from AR coating, but you can remove the AR Coating with AR Stripper. http://optochemicals.com/products/info_ar_stripper.htm Quote Link to comment Share on other sites More sharing options...

watcher Posted July 22, 2006 Report Share Posted July 22, 2006 Nice to see a dealer with a good after sales option. I recived one of these crystals and as the jeweller says, no contact should have to be made with the inside layer. Care is needed with these crystals when cleaning them before install. Opthalmic companies use a hydrophobic layer to toughen the finish but I doubt the asian factories do the same. Maybe David can tell us how it is applied.

Finepics Posted July 22, 2006 Report Share Posted July 22, 2006 Davidsen is indeed a top man. I will tell you that the crystal on my Honpo 187 was covered in scratches on the inside. They are not visible from the outside though. Quote Link to comment Share on other sites More sharing options...
