BigCrown Posted February 7, 2011 Report Share Posted February 7, 2011 Manufacturing the Dome Crystals for PAM 212 and the larger PAM 127 Okay fellas, I thought I would pass along the information I have learned on the latest 1:1 crystal project. Below are the steps that Panerai's sub contractor uses to make one of their crystals. The biggest hurdle, I am told, is the set labeled number 5 above. If the second mold is not lined up perfectly, the whole crystal is considered a 'reject' and is a waste of product. In mass manufacturing like this, a loss of over 5% can be disastrous to the bottom line. This is why (I believe), this project has never been completed to anyway near 1:1 proportions with genuine sapphire. ***** This is how a mineral crystal is made: Obviously, the mineral crystals are easier and far cheaper. But they will break easier. Quote Link to comment Share on other sites More sharing options...
Watchmeister Posted February 7, 2011 Report Share Posted February 7, 2011 Very interesting info. I guess it makes me feel better about the cost of a gen crystal. Can't wait to see the results on your new crystal. Quote Link to comment Share on other sites More sharing options...

Polynomial Posted February 8, 2011 Report Share Posted February 8, 2011 (edited) This makes me wonder how did DSN make his 'sapphire' 127 crystals, can't imagine a rep maker going through this process Edited February 8, 2011 by Polynomial Quote Link to comment Share on other sites More sharing options...
Jkay Posted February 9, 2011 Report Share Posted February 9, 2011 That's fascinating. Thank you for posting this info. Quote Link to comment Share on other sites More sharing options...
cloner4 Posted February 9, 2011 Report Share Posted February 9, 2011 dsn crystals are the regular saphire, not anything innovative...Crown is out there doing what NO rep dealer or manufacture has done, this will be true OEM crystal Quote Link to comment Share on other sites More sharing options...

How is that done? Quote Link to comment Share on other sites More sharing options...
cloner4 Posted February 9, 2011 Report Share Posted February 9, 2011 i doubt dsn or any other rep manufacture makes it to oem standards..ie: AR, shape, fit etc.. Quote Link to comment Share on other sites More sharing options...
capice Posted February 9, 2011 Report Share Posted February 9, 2011 great info, I think it is far too expensive for our dealers to make these unless large quantities Quote Link to comment Share on other sites More sharing options...
kbiz Posted February 9, 2011 Report Share Posted February 9, 2011 DSN is far from a perfectionist! He takes the first pass on whatever the manufacturer gives him so he can put that part/build up for sale asap... the crystals use the heated process for all parts of the machining process... so rather than grinding the inner curvature, they further reheat the sapphire and press mold them onto the 2nd form... this is why they have so much distortion... so very much distortion it's more than just a tell it's a joke. This crystal project is one of the most ambitious projects to date... I'll buy a couple just to support the effort! Quote Link to comment Share on other sites More sharing options...
Fi5herman Posted February 9, 2011 Report Share Posted February 9, 2011 kbiz, that's true. That's why i hope this project can proceed too. Don't think we can get such gen like domed sapphire anywhere else. Quote Link to comment Share on other sites More sharing options...
chinsk Posted February 9, 2011 Report Share Posted February 9, 2011 I too have faith and have ordered a couple 127s and a 212/253 xtal. Really hoping it happens and thanks for the info! Quote Link to comment Share on other sites More sharing options...

cloner4 Posted March 9, 2011 Report Share Posted March 9, 2011 guys hate to be the bearer of bad news but sadly Crown didnt get enough orders, so the refund process will start soon :( he was a few thousand short and it doesnt make sense for him to fit the rest of the bill, a good and honest guy maybe some other time Quote Link to comment Share on other sites More sharing options...
