Hi, I am new to this forum. I just got a wonderful IW3902-08. As it was not the current model, so I tried to find some specification about this watch. I learned from some web site that my watch has anti-reflective treatment on both sides of the sapphire crystal, but some did not mention about this point. So may anyone tell me whether the sapphire crystal has anti-reflective treatment on both sides?
Thanks a lot.
Hi EDKWOK422 and welcome to the forum.
Congratulations on your beauty, pictures please !!!
They are treated on both sides, see the "case" section here:
Hi Tom,
Thanks a lot for your information. Please find pictures of my watch below
My share
Congratulations on your watch! I've always liked this boutique only release :-)
Thank you :)
I like this watch very much. The combination of the dial with sub-dial, rubber strap ... especially the size 45.4 mm of this watch. I prefer this size more than the current size of IW3905.
I just found from IWC web site that the watch IW390216 does not has ant-reflective layer. So, I am thinking maybe my watch (IW390208) also same as IW390216 instead.
Really? Where does it say that? Are you noticing reflections on the inside of your crystal? Somehow I doubt it. Relax and enjoy your watch - it's a beauty all right. I believe that all contemporary IWC watches that share the same first four reference numbers (in this case 3902) also share the same crystal. The anti-reflective coating on both sides of the crystal is noted in the information on the ref. 3902 when it was introduced in the 2010/2011 catalog.
Hi Ben,
Thank you for your information. Please advise where it is feasible to find the 2010 / 2011 catalog online? Actually I really not mind whether my watch has anti-reflective coating on both sides of the crystal. It juts sound stupid to tell wrong information when someone asking me the technical information about my watch . haaa :-)
Hello EDKWOK422
I'm sorry but I actually have a hard copy - I do not know of a link to an online copy of the 2010/2011 collection. Being a boutique edition, it may be quite hard to track down much documentation on that particular piece. Your best bet might be to search for an available hard copy of a catalog from the years the IW3902 was included.
Too bad there is no available online resources for knowing technical details of 390208. I found that there was online resource of IWC work book, but the site does not work.
Anyway, thank you for your reply. Maybe I can ask the staff associate at IWC flagship boutique to request them answering my question. It is lucky that Hong Kong has one flagship boutique. :-)
The Cellar very kindly posted PDF links to the following Catalogues
2010/2011, 2011/2012 and Aquatimer Collection 2009

Thank you Mark :-)
I found the catalogue of 2011/2012 from the Cellar's posted link. Really very useful information.
