I will have to stop shining LED maglites in my eyes Chris because I don't see any distortion, i see a great looking (IMO) sapphire upgrade with the added bonus it is domedDomed sapphires are always lovely. I like them very much.
The only thing I don't like about them is when they deform the original dial aperture.
So a double domed sapphire is the answer to keep the dial look original, without any distortion whatsoever. Think the SBBN007 tuna crystal. It is double domed and the dial does not get distorted. I think that if you could get your domed sapphires without distortion, then it would be great.
