Rolex Submariner Date 116610LN - Black Lines Tarnishing?

[rdizzle92]

Hi everyone,

I noticed that the oyster stainless steel bracelet on my sub and even on the back of the case it is starting to develop faint black lines..

Are these bracelets known to tarnish or discolor and develop black lines? Can it be corrected with a professional polish from RSC?

I've searched on various watch forums and can't find any one else reporting this issue.

I've attached some photos for your reference.. any insights is greatly appreciated. Unfortunately my iPhone 14 is not great at focusing so these were the best photos I was able to take.

The watch was produced in 2015 btw.
