I bought a Breitling Superocean Heritage Chronograph about 2 months ago. Yesterday, for some reason I just couldn't get the crystal clean. No matter how much I wiped it, it kept looking smudged. It was pretty frustrating, but then I noticed this mark between the 4 and 5 that would not wipe away. It almost looked like it was under the crystal. Then, later that night the mark was gone, then it reappeared, then it wasn't there when I woke up this morning. I put the watch on this morning and while getting ready for work, it came back.
I feel like I'm going crazy, but I was finally able to snap a picture. I attached it. Anyone have any ideas what this is?
