Yesterday I was able to hold my skyland next to the gen. I found that the rep AR seemed quite a bit more blue than the gen. Could it be that we think good AR is blue, instead of focusing on how well it reduces reflection on the crystal? Gen AR seemed to reduce quite a bit more glare than the rep. Thoughts?

Rep AR too blue???
- Thread starter trevor2079

I have been saying this forever. I see people going out and getting quintuple AR on their watches when it doesn't need it. I understand the original may have had it but often replication of the original effect can be accomplished with single AR. And certain rep models do have AR overkill. Yet of all the things people could complain about that is never it. They apparently are more worried about a lume dot that isn't bright enough.
Yep, sadly this isn't anything new, Trevor.
Too blue? Probably. Is it even *true* AR coating? I don't know. Like all things, I'm certain there are differing qualities of AR coatings and differing skill of AR coating appliers. I'm certain the quality of the coating and the skill of the coaters for our reps is no where near Breitling's source. :wink:

I have a 111H that has AR which makes the dial look blue too. Doesn't look black at all. Rest assured this isn't very true to the gen. Panerai uses single sided AR on the inside of the crystal only.
Heard Cheif will be offering an AR service of a specific brand, using the same AR coating process as Omega and potentially others.
Might be interested in that.

Can someone link me to how AR is done?
thx
always love to learn new things so will make for a good read.

but what I'm trying to figure out is:
"AR coating is the depositing of one or more layers of oxide materials with a reflective index on either one or both sides of the crystal."
hows that done? - what oxide materials do they use?
- is it different for each watch company (I know the doing both sides and such, but are the materials used pretty standard across the board? .. or do they vary with company.)

Ah. I didn't go into that in my tutorial because I didn't want to bore the crap out of everyone. But if you want to know.
You need a vacuum chamber to do it. Very expensive equipment.
There are two primary processes used for AR:
Broadband (BBAR) which is also called Multi-Layer Anti Reflection (MLAR)
These are the most expensive processes and the ones used by the top level gen makers.
Laser Anti Reflection (LAR)
This process is mainly used for things like computer displays and TVs. Mostly an anti glare process than anything.
Do not confuse the term Multi-Layer Anti Reflection with Double AR. Multi-layer describes the procees not the numbers of sides it's applied to.
AR films can consist of a variety of compounds or depending on the material or 'substrate' that it is being applied to. Different manufacturers use different ones. Don't ask me who uses what because I don't know. All I know is the three most comonly used on crystals are:
Zirconium Oxide
Titanium Dioxide
Magnesium Oxide
Compounds used for materials other than glass are:
Tantalum Oxide
Nickel
Hafnium Oxide
Copper
Gold
Silver
Indium Tin Oxide
Silicon Monoxide

A lot of the time what we see on reps is not really AR, as much as a blue tint. Genuine AR can be just as blue in color as the rep, but you just wont see it from all angles. It is more subtle, and more effective in the way it reduces glare.
BTW, Panerai AR is in most cases purple, not blue.

To clarify further what andreww is talking about. If you have good AR not only will it be invisible from certain angles but it can effectively make the crystal disappear. Here are some pics from one of the SOSFs I did that may show it better.

Are you a chemist?
I'd just add that there are also single layer coatings, but I don't believe that there are any that will achieve gen or the latest chieftang specs for antireflectivity and still provide a blue hue. The predominant resulting hue seems to be green from those.
No I just like to know why things work on a Starship.I'm addictIed. I hope you guys realize I do it all for you.
