Yours is simply a dial variation, seen a lot in the late 1920's/early 1930's.
Although the jewel count is different and the bracelet too.
No biggie.
"Sky King"??. Nothing like a Sky King Jim! :-)
Edit- Looking again, there are some subtle differences.
Notice the lugends? Different shape and some off-set engraving on the tips.

Here is one in the DB from 1929

Exactly like yours Jim, except it has a radium dial.
