I have a small crack in a plexi crystal which has a tension ring fitted. My question is rather tha fork out for a new armourlite crystal, can the crack be repaired? If so, what can I use.
Thanks.

Replacement is easier, but if you get super glue and carefully put it in the crack to fill up to the surface, then sand it back flat and polish it up. Superglue has a similar refractive index to perspex and isn't easily visible if done properly.
Do this with the glass out of the watch and completely clean so nothing else is in the crack.

However, if the crystal has to come out surely it makes sense to fit a new one?

A new lens/ glass won't cost much, so easy to get someone to do it, or have a go yourself.
Go for it.
Definitely wiser to replace. These glasses shrink at the edges over time and once out don't seal properly again.

I concur. New crystal will be a few pounds at most. Fitting is a doddle.
Disagree! If you find it so easy I must be doing something wrong when I fit them.Quote:

Ideally, you keep a stock and you always have the right one to hand, but on my scale it isn`t worth it. Sods law states that you very rarely have the one you want.
Fitting plain acrylic crystals is a whole lot easier, the tension ring crystals can be a challenge. If it goes in using thumb pressure only it's not tight enough and it'll probably leak; Brenden's comment is correct, they do shrink slightly when they're old.

The super glue trick did not work at all. If fact it made it worse. I have since ordered a couple of new one's.
I have used it before on irreplaceable ones that can't be custom made as very unusual shapes, I would always replace if possible.Quote:

Do you have a press for fitting the dome?
A press is essential

New acrylic arrived and sitting very pretty in the Roamer. Thanks for all the suggestions.
