This watch was previously ID'd as a Ambassador "A", but after acquiring a 1939 Ambassador and compairing the two, it belongs in the unknown catagory for now until another Lone Eagle "A" ad shows up. ;-)

Case & crystal dimensions 41' Unknown
Lug to Lug, 37.2mm
Length, 28.6
Between lugs, 8mm
Width without crown, 24.8
Crystal Groove, 23.8 X 17.8mm Curved both ways
Crystal, 23.7 X 17.7mm Curved both ways






Take a look at the 1940 Ambassador that Jerin has in the database, and the 1940 Montgomery that Mark has in.
Note the lugs right near the end where the spring bar goes. You will see a ring about 1mm from the ends.
This unknown and those two all share that ring, they are all 17J models and I would bet they all have the same case/crystal specs.
None of the other Ambassadors from 39-41 have that.
The Ambassador "C" that Gary has in there has a 7AP movement and a recessed crown, that might be the Montgomery.

I strongly believe that Fifth's watch is not a Montgomery. Check it against the ad--you'll see more differences in case design than similarities (and he agreed with that in our discussion about it). He changed it from the Ambassador based on jewel count alone.
I have observed the rings, as indicated above. They do not account for the differences in case and lug design between the Ambassadors and other mentioned models. IMO.
Gary's "Ambassador" is likely an Oxford, based on this discussion http://www.mybulova.com/watches/1940-oxford-1976
In reply to NOVA, The lugs match, look by FifthAvenueRes…
AMBASSADORS are 21 Jewels
the Watch I own matches Tickers unknown shown, minus the engraving.
Paying close attention to the artists rendition of the lower Right lug:
The Case stops, forms a break, the lug then extends off, curves and enters the strap.
If I were to place this Watch on a leather strap it would look identical to the Watch in the ad, minus the case engraving.
'COMMODORE'
The ad states the Watch is available on a bracelet or leather strap - these lugs are set up to accept both.
**edit, OK Greg I see what You mean.
doesn't change My view.
: )
The notch which is cast or machined into the lug is to prevent the leather strap from shifting from one side to another.
