Watch is in same used condition as when purchased; although I may have had it serviced...don't recall. I'm posting because there is no 10BA ss movement listed here...that I could find... and to learn if this model finally has a name.

The 10BA and 10BAC are both from the ETA 900 ebauche. Technically, this example should have been stamped 10BAC but was modded specifically for Military use. It's not a Military contract watch, but clearly could be used as such and may have been available in kit shops.
Stainless back is standard, but Sterling with gold fill is a bit unusual, called Vermeil.
Looks like an Air Warden to me...
I wonder if the sterling was substituted as a result of the war effort to use steel for armament?
I'm pretty sure that is the reason.
Gruen was doing the same during this time period. US joined the war effort before we joined forces.
Air Warden gets my vote.
I'm good with the Air Warden.
1944 (by case number) Air Warden
We have several watches ID'd as Air Warden. Some have slight variations inb the dials but basically all the same case.
1944 Bulova Air Warden
While the Air Warden and the Medico appear to use the exact same case from 1942-1949, there is a defining difference. The Air Warden uses a 15 jewel movement with a small seconds. The Medico uses a 17 jewel movement with a sweep seconds. All of the ads for both the Air Warden and Medico support these distinctions.
