Most eBay sellers used to provide a new tension ring with a new crystal, but I haven't seen any lately. If that is the case, then you can just reuse your old tension ring. Just make sure you have the ring positioned correctly inside the crystal, the crystal positioned correctly over the case, squeeze the crystal press and it snaps right in. You'll even hear a 'click'
I'm beginning to have second thoughts about scavenging my vintage Amphibia in a 320 case for parts (the one you helped me verify when I was shopping it on eBay). I've sort of grown to like it quite a bit. However, by mistake I happened to wear it while taking a shower. I noticed it after only a few seconds and took it off and wiped it (somewhat) dry but still some moisture could be seen building up on the inside of the crystal. It dried up after an hour or so, but obviously it is no loger water resistant.
So, I'm considering getting myself a set of new rubber seals like
this and a new acrylic glass like
this. I don't have the tools to replace the "crown tube seal with fixing washer" (which I guess is what's being replaced
here) or the crystal. Of course, I don't know where it's leaking but I guess or rather I'm hoping that replacing the case back seal, winding crown seal (can it just be winkled out?), and the crystal will do the trick. What do you think?
Anyway, I've been searching for a clear and easy to follow instruction on how to replace the crystal, like a video or a step by step written instruction and the closest I've gotten is your quote above (thanks!). I also found these
two videos but non of them feel very reassuring but maybe they're OK?
So, in short what I want to know is; how do I make my vintage amphibian water proof (preferably 200 m), what tool or tools do I need to change the crystal and how do I do these things? I realize the answer could be a very long one, but for now I would be more than happy to learn a little more about how to change the crystal. Thanks!
