166.010 Black Dial Check

Recently saw this come up for sale. I've never seen a 166010 with this configuration. Hook on the Seamaster, lettering as described is white, whereas all examples of 166010 with black dials that I am aware of are gilt, text looks quite thin to me but not sure. The black looks more matte when compared to other examples of black dialled 166010's, which all seem glossy.

I was shared a link to a different watch that was sold online elsewhere years ago that looks virtually identical, except for different movement serials (pictured below). No better pics unfortunately.



Thoughts?
