Help with smudge under crystal on dsotm

Thanks - your post triggered a vague recollection of some notice I had seen at some point in the past, so I did some digging this morning (there are a lot of these notices I see so it didn't click immediately yesterday when I read this thread). Indeed there was a notice issued in the beginning of 2016 regarding problems with some sapphire crystals showing "wear" of the AR coating prematurely. It lists the affected crystals (there are 7 listed) and one is indeed the crystal for the DSOTM.

The document does indicate that the crystal will be exchanged under warranty (if the watch still has warranty), but the shop that does the repairs (if you don't use Omega directly) would have to buy the crystal up front, then return the defective one for credit. If the watch doesn't have warranty, then they may do it as a courtesy repair, but that would be on a case by case basis I suspect.

The OP should take the watch to an Omega Boutique or send it directly to a service center if it has warranty, and they should replace it.

Cheers, Al
