Fitting a crystal to a Quadron case

#1 Post by thojil » Thu Apr 18, 2013 1:28 pm

I started searching for a crystal fitting my Quadron 82 "157-8" (Bruce Shawkey, A Collector's Guide, page 19) and realised when measuring the bezel that there is not the usual lip that holds the crystal in place. It doesn't look like it was ever there as far as I can judge. If the bezel is correct how on earth do you fit the crystal?

Has anybody seen this before. Did the "157-8" crystal have a special ridge to avoid it falling through or is the bezel incomplete and the lip is simply missing?

Didn't have time yet to make pictures, but I hope my explanation is clear enough.

I have a vague memory, of a post, somewhere, that said, there was a metal gasket that fits in side the bezel that holds the crystal in. I think it was by Cary?
I check my 157 to see, I will post my finding , if necessary
Best I can do

Thanks Bazzab, but then again it is not helping me really..... as I don't have the bloody gasket ;) Would it be possible for you to post a picture so I know what this gasket looks like. Or even better if anyone has such a gasket to spare please let me know.

It's not really a gasket. It's more like a bezel within a bezel. It's a small metal frame that the crystal is cemented into, which "floats" over the dial and is locked into place by the outer bezel. I have no idea what the designers were thinking.

The usual approach when these are lost is to use a slightly oversized acylic cylinder crystal and file a step into the sides to allow the bezel to hold.

Thojil, I haven't looked through my meager assortment yet for the 157/8, but I'm 99% certain that's one of the models I actually do recall seeing. Regarding the missing bezel insert, here's a picture of a complete green gold 157/8 case:

I'm sure you can see what's missing. I'll shoot you a PM this weekend about the requested crystals and this case.

Thanks all for the explanation, it's perfectly clear now. And it is not a small part that is missing, it's like half of the case is missing :shock:

Afire, much appreciated if you can help me out with this one.
