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.
We've now seen the 'CLIPPER' style Dial advertised in a 'MINUTE MAN' Case.

* Based on this information I'm going to say unseen 'AMERICAN CLIPPER' variant.

Agreed, AC unknown variant.
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.
AC, unknown variant
AC unknown variant
Agree AC unknown variant.
I have the same watch with the same dial but my dial is white.
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.
I am sure that the dial is an aftermarket replacement.
Usually the genuine Bulova dials had raised applied numvers, but this one is simply painted on.
But good to see the dialog pick up again this long after the original posting.
