What does the term AR for crystals mean ??
I have seen this for months but don't know what it means.
Thank you for clarifying

Anti-Reflection

It's a chemical coating that reduces glare and reflections on the crystal.

 

[Raddave]

its a coating that is placed on the crystal , an Anti-Reflective coating....hence the term AR

What they said and a reminder that the only dumb question is the one that goes unasked.
If we don't ask, we don't learn.

A/R to me simply means: Crack Cocaine. I can't get enough of it.

Thanks for clearing up.
Since we're on the subject of stupid questions, help me out here also.
What is a sandwich dial on the Pams?
What other type of dials are there ?
Thanks in advance

sandwich dial is a dial with 2 parts, a baseplate and a upper place with cutouts. the baseplate gets lume, and the upper place, which has the cutouts of the numbers/markers is placed on top of the baseplate.

Hi all,
First post on the forum!

Could somebody explain how AR works?
What is single sided AR and which reflections does it reduce?
What extra reflections does double sided AR reduce?
If you have a bluish tint with AR, does that mean the AR is good or not?

Thanks!

One of those questions that's hard to look up using the search feature since it has less than 4 letters.

Sorry, got carried away on the topic and still a noob !

You are not stupid asking for the things you don't know and which we all didn't know sometime ago.
This is one of the purposes of the forum : sharing the knowledge
Stupid is to search Dealers by yourself and buy from them. To buy things without knowledge and after that asking in the forum for a solution to the problems.
You, my friend are making the correct and you are in the good way.
Ask all you need and we will reply asap.

Concerning AR you have alredy the reply from othe members.

Concerning Sandwich and Sausage dials or other matters of Panerai you should read the PAM REVIEW-GUIDE.
"Reference PAM REVIEW-GUIDE" - Replica Search, Identification, Evaluation & Selection

You have below an extract from the GUIDE about terms of Panerai dials:

Sandwich (dial)- Sandwich dials are where numbers and minute markers are cut out of the metal plate which forms the visible dial (behind the crystal). Behind this is a second metal plate with recessed areas where a thick luminous paste is applied, the areas corresponding to the cut-outs in the first metal plate, thus “sandwiching†the luminous material between the two metal plates.
Sausage (dial)- It is a dial with just one layer where the luminescent material is applied directly over the dial markers (usually embossed) and the final appearance is like a “sausageâ€. By extension we have called Sausage all non Sandwich dials
Hobnail- It is a type of texture engraved in the surface of a Panerai dial
Flat dial- Dial with non textured or engraved surface
Lume- It is the system used for timepieces to be read in the dark, a luminescent material is laid on the dial indexes and hands.
Luminova- Modern luminescent material currently used for the lume in the Panerai watches
Patina Lume- Sometimes the luminescent material of a lume achieve an aged colour (patina) by the passage of time. You can use an aged lume colour (patina lume) to simulate the patina of an old dial.
Tritium (lume-dial)- It is the name used to nominate the dials which have a Luminescent material based in Tritium. Used by Panerai from 1946.
Tuxedo- It is a type of texture (parallel lines like) engraved in the surface of a Panerai dial (PAM 029)
Woven- It is a type of texture engraved in the surface of a Panerai dial

I hope all is clear now

As above said AR is a coating layer applied to the surface of the Crystal of the watch which avoid the reflections and then you have a more clear sight of the inner dial.
Single AR is applied just in a face of the crystal. Usually in the inner surface because the coating material is easier to get scratched than the material of the crystal.
Double AR is applied in the two faces of the crystal. Then the external layer is sensible to scratches and you must be careful. In the other hand a double AR should mean more antireflection effect. But that depends on the quiality of the AR and the quality of the crystal.
The coating material of the AR can be colourless and many times has a little coloured tint: Blue, green, purple... That is not sign of better quality or poorest quality it is a characteristic of the AR material.

ANYHOW: As always in the rep world, the best AR is the AR close to the Gen in application, colour and effect
