Morning,

Anybody have any idea what size an original Olympos crystal is? I'm preparing for the worst as the one I've recently bought has a couple of deep burns. It looks like it might be an armed crystal, but without having it apart I won't know.

Going to break out the polywatch first, then Micromesh if I'm not happy. I can't see me removing all of the marks, but I'm confident an improvement can be made. Least intrusive job first.

Honestly it depends, as I have seen a couple variants for the original Olympos.  It is just a friction fit domed acrylic, dependent on size (around 30.5/30.6 I believe), but some have a flat trim ring and I have had others that required a stepped trim ring for proper fitment.  Why the variation in fit for the same model, who knows.  Some of the other Zodiac models are worse for numbers of crystal variants, while looking relatively identical on the outside.

Thanks Ultra-Vintage. Never a quick fix...

I'll see how I get on
