GS 5646-7010

Just to make sure: were you aware / did the seller disclose that this was a redial? There were no black dialled versions of this reference, only white and blue.

They did also make silver dials of this model.

Yes, that is true, they turn quite dark over time, I have a 4522-7000 that has had this happen. However to my eye this is all black and also (again to my eye) has a different finish to the dial surface, like there is a thick layer of paint / lacquer, whereas the original is very flat. Furthermore, the hour markers should be silver, not white, and the same applies to the minute hand.

Black ones are indeed quite common among eBay sellers etc, however they are not original. Many original examples have suffered water / moisture damage at some point, and have been repainted - sometimes black, as that is quite popular with buyers. Similar thing to what happens to vintage Omegas etc.

Here’s one that is all original: https://thegrandseikoguy.com/product/grand-seiko-5645-7010-blue-dial/

Edit:
Accidentally linked a 5645 instead of a 5646, here’s the one I meant to refer to, however of course the dials are pretty much the same: https://thegrandseikoguy.com/product/grand-seiko-5646-7010-2/

Gee who revived this? That sent me down such a rabbit hole on GS it was actually kinda interesting. I’d still like one someday but put it aside after this mess up. Everything worked out though seller was a good guy lives not too far from me we still meet on occasion. I think he sold it correcting the description to “redial”. I really like those old GS but when there are so many watches you like no sense to get overly hung up on one.
