Weird Smudge in Middle of Apple Watch Series 3 (Stainless Steel)

Hey there!

I am having something weird happening on my Apple Watch, and I am not sure if it is a defected or not. I have a weird smudge (that can be cleaned away) in the middle of the watch that shows up when I grease up the Apple Watch screen. It's very easy to find and worries me something is actually wrong. I had an issue with my iPhone 6 Plus (At first launch) which was similar, with a C shape always being seen that was under the surface of the iPhone, but that couldn't be cleaned away, while this issue on my Apple Watch can, but comes back very easily by greasing the Apple Watch. It is hard to explain so I have taken a picture to show what I mean, which you can find at the bottom of this post. Hopefully, that helps!

I was wondering if anyone else has had this problem, or if anyone knows if it is a genuine problem, or me being paranoid.

Sorry, the picture is up the wrong way, I simply didn't wanna rotate the photo, but the issue I am referring to is clear in this photo anyway. 🙂 🙂

Thanks

Alex 🙂
