Tempting to call this a Sky King but it could as easily go down as an unknown.
The movement is a 17J 10AN which is consistent with a Sky King. The case is marked "Bulova Quality". Both are 1931.
It runs. I relumed the hands but its otherwise as I bought it.
This one is definitely different. The shape says "Sky King" but the gold filigree on the bezel is unique. In fairness, there does appear to be some variation in the gold pattern in the Sky Kings but I've never seen one where the gold in the bottom and top borders is vertical and not horizontal. Regardless, I think its a cool design.
