Grey Market Yachtmaster

[Thunn]

Hey guys, have been lurking on the forum for several years. I now have my first question which I am seeking outside input. I have an opportunity to purchase a 2019 steel yachtmaster blue dial. It has all the boxes and papers. Purchase date was 1/22/2019. The watch looks great. I have purchased several watches from the dealer over the years. He did inform me the bezel was sandblasted and polished. It looks good and I am likely not good enough to notice anything on my own. He is offering it to me for around $1,000 below retail. How does this kind of work on the bezel impact the value as well Rolex RSC service in the future.

Thanks for your input.
