Sapphire glasses aren't worth the price premium over mineral glasses:undecided:
Go ahead and scratch each one - there isn't a great difference and its not like they're better to see through.
Are aftermarket sapphires not as good as original?
I have a tissot with a plain sapphire and victorinox with an ar sapphire and especially the tissot, it's been worn to death, bezel is scratched but glass is 98% victorinox has been worn with much more care and is 100%.
The other reason I got the sapphires is I couldn't find a plain glass for 6105 for any less. I got both the sapphires for about the same price as 2 glass crystals from sellers apart from mountapo.
Guess this will be an experiment to see what there like as both of these watches will be keepers.
If normally agree with you Dr, I've been very impressed with the hardiness of most glass replacements, I have one on my 6309.
