Replacing Seiko Hexalite with a Sapphire Crystal?

[Lol-x]

Many of the Seiko models come fitted with the in house Hexalite crystal.

I think the Hexalite is very good and is a compliment to Seikos manufacturing ability for very reasonable price watches.

However the Hexalite is in most cases without anti-reflective coating and it less scratch resistant than sapphire crystal.

Enter the notion of an aftermarket sapphire crystal with anti-reflection treatment on the underside of the crystal.

My query is regarding the anti-reflective sapphire replacement crystals appear to come in 2 different types:
1. clear crystal; or
2. blue tint or coating.

I don't understand what the 'blue' is all about and whether it is in any way an advantage or disadvantage?

I would have thought one may have wanted to get a clear untainted view of the dial but the 'blue' coating/tint seems to be quite popular although I have not particularly been able to see any good examples.

Thoughts and opinions much appreciated

Done this quite a few times with turtles. The blue helps bring out a blue dial more but it is not that big a difference IMO.

So what does that mean for the black dial watches?
Is it just a gimmick like the green crystal on a Rolex Milgauss?

I had a modification done on my SKX 175 by NEWW. I had them change the Hardlex crystal to sapphire. Also replaced the dial, hands, chapter ring & strap.
