I'm sorry JB, I overlooked editing the pic. names.
I realized after looking at them post. Sorry again
I think it will be President "A" with charcoal dial

I agree with President, though other charcoal/black dial option had their own variant, and I believe this one would also. I cannot find the black dial variant in the ads, but 'B' was listed as having a black dial per the 1958 price list at $49.50. Not enough to go on for me, so Pres w/o variant.

Black variant is "D", but they have another lugs

In reply to Black variant is "D", but by jabs
Yes, 'D' is a black dial variant, but not the match to subject watch. I believe it is a different style all together, perhaps similar to the C, as the band is the same as C. Rather hard to tell due to the poor image quality, but I do sort of see only the 3,6,9,12 markers.

Dial looks original .
It's a President alright but I agree with Ken, no variant is clear to me. It's a nice looking watch.

Thanks Geoff. Love these slim line models, especially the black and gold. Just got a 58 president, found it in a junk watch lot...
