I am a little conflicted over the ID on this one. All of the other Clipper models have even numbers only where this one has all 12. The minute track looks correct and the seconds track as well. I just viewed a 1937 Commander with the white face and this now seems to be what this watch is only with a black face. http://www.mybulova.com/watches/1937-Commander-50 - Is it possible that this is a Clipper case with a commander face? Looking closer at the two cases there are more tiers on my case than the commander case.
I have an ad showing the American Clipper C with a black dial but it utilizes numerals and hashmarks like the Minute Man above. Not an exact match but I'd bet we're looking at a C variant.
American Clipper for sure, need another ad to confirm the dial and variant designation.
American Clipper.
Black is the most common colour for a re-dial. If a watch of this age doesn't have some serious patina on the dial and markers, there is a strong possibility it was refinished. The older re-fins are less accurate than they are now, so this is also a giveaway.
I think it's quite likely this is a re-dial, but the AC designation fits.
