vlydog Posted June 18, 2007 Report Share Posted June 18, 2007 Can anyone tell me where I would find a sapphire replacement crystal that does not have AR for an IWC 3717 pilot? I would also need a part number or a more detailed description for ordering. Quote Link to comment Share on other sites More sharing options...

Pop the crystal, measure it with calipers, and then look for a replacement based on your measurements from a place like OFrei. Quote Link to comment Share on other sites More sharing options...
Amplitude Posted June 19, 2007 Report Share Posted June 19, 2007 If you haven't broken your crystal, and you want the AR gone, use a buffer wheel with white media, or a dremel. It'll take the AR off in less than a minute. Quote Link to comment Share on other sites More sharing options...

This is all in preparation for mods that will be done later this summer. I would actually like to go ahead and purchase an extra crystal without AR. My plan was to put it through with Chieftang's next run. I don't have the watch so I can't just pop off the crystal and measure it. If anyone knows the size and parts number for this crystal I would be grateful. IWC 3717 pilot. Best regards, vlydog Quote Link to comment Share on other sites More sharing options...
Amplitude Posted June 19, 2007 Report Share Posted June 19, 2007 Aha. I actually have the same watch on the way to myself. I'll be doing this mod too, and the ETA datewheels. I asked Chieftang about the next AR run, and he said to just watch for it. If I was you I'd just wait til you get the watch and pop the crystal out. That's what I'll be doing. (Have a watchmaker do it for you if you don't know what you are doing and are nervous about it.) Quote Link to comment Share on other sites More sharing options...
dluddy Posted June 19, 2007 Report Share Posted June 19, 2007 The AR that comes on the 3717 crystal is fine as is. I don't see a need to do the Double AR on this model. Quote Link to comment Share on other sites More sharing options...

Those pics of one with the coated crystal in the "3rd AR" thread looked very nice in comparison to the unmodified pics. Quote Link to comment Share on other sites More sharing options...

The trouble seems to be that the Rep cyrstal with have some degree of AR on it already and would have to be removed if you plan on using that crystal. I don't want to do this myself. This is why I planned on getting a seperate non-AR cryatal to send off to chieftang. Quote Link to comment Share on other sites More sharing options...

Go to an AD and check the genuine No doubt the Double AR is awesome. Just had 2 done and plan to contribute to the next run as well, but this one is close to genuine AR out of the box. I have handled them at an AD. Ultimately it is personal preference Quote Link to comment Share on other sites More sharing options...
