AR coating issue/defect on new Sinn 556
Hi everyone. Bought this 556i from WatchBuys 4 months ago. I noticed a while back that I had a mark/scuff on my crystal around the 12 index. Just assumed I scrapped off the AR coating from hitting the watch against the bottom of my desk or something.
Today though I thought the “scuff” looked bigger and decided to take some pictures. Zoomed in, it looks like the AR coating is cracking and failing… for lack of better description. It doesn’t seem like this is from physical damage and I’m almost certain it’s gotten bigger since I first noticed it.
Anyone seen this before or dealt with a similar issue?
Gonna reach out to WatchBuys, but wanted to see if anyone in the community might know what this is.
Thanks!
