kye_lin Posted October 28, 2008 Report Share Posted October 28, 2008 Hi.. Anyone tried PVDing a movement?? The bridges specifically... Will the jewels be affected by the process?? Will they melt?? THanks.. Kai Link to comment Share on other sites More sharing options...
andreww Posted October 28, 2008 Report Share Posted October 28, 2008 Movements are made to very tight specifications. As PVD is a coating, it would alter the dimensions of each coated piece, rendering it useless. Unless each piece was constructed with an allowance for the thickness of the PVD... but the short answer is no. Link to comment Share on other sites More sharing options...
kye_lin Posted October 28, 2008 Author Report Share Posted October 28, 2008 I just want to coat the bridges... I am concerned about the jewels... Do I have to remove them before the process?? I have seen at least 2 6497 movement bridges PVD coated by members of the forums... with no issues.... just cannot find the threads... How about the SOPROD modified PVD 6497 movements?? They are modified aftermarket so to speak... I am sure it can be done... Cheers... Link to comment Share on other sites More sharing options...
Guest avitt Posted October 28, 2008 Report Share Posted October 28, 2008 krnbk2 from RG coats them without first removing the jewels. Link to comment Share on other sites More sharing options...
RobbieG Posted October 29, 2008 Report Share Posted October 29, 2008 SOPROD are the only ones I know of. The process is very tricky and very expensive. They are also phasing them out. There won't be any more made there for a while so if you want one you should grab it soon. http://www.wiegandwatches.com/index.php?ac...19ba59c4e3f5956 Link to comment Share on other sites More sharing options...
kye_lin Posted October 29, 2008 Author Report Share Posted October 29, 2008 I am PVDing another movement.. not 6497... Anyway.... there is sandblasting/beadblasting in the process... prior to coating.. I am concerned it might just damage the jewels... krnbk2 from RG: did he sandblast/beadblast prior to coating?? Thanks all for the help much appreciated.. Link to comment Share on other sites More sharing options...

The PVD movements that I have seen have all had a CDG finish, so no bead blasting is necessary before coating. Link to comment Share on other sites More sharing options...
kye_lin Posted October 29, 2008 Author Report Share Posted October 29, 2008 Good idea... then maybe I can just leave the jewels in... Link to comment Share on other sites More sharing options...
Guest avitt Posted October 29, 2008 Report Share Posted October 29, 2008 Good idea... then maybe I can just leave the jewels in... I say go for it! The worst thing that could happen is that one or more of the jewels fall out in the process, or crack from the heat. Even if this were to happen, it's easily correctable by a watchmaker.

Logan Posted October 30, 2008 Report Share Posted October 30, 2008 Someone posted a while back about DLC coating the movement plates in a seconds at six 7750 to reduce the friction between the plate and the transfer gears. I don't know how successful it was, but it might be worth finding the post and investigating further. Link to comment Share on other sites More sharing options...
