Bulova 1923 8 Days

Yes, without reference it makes matters a little more challenging.

Seems to me like the brigade level (several companies combine to make a Brigade) maintenance were required to keep the 'official time' with an 8 day clock...one of our ORD Tm's mentions calibrating watches to the 8 day clock....maybe this is it???

Agree it could still be aviation, I only meant that IF it had a magnet, it would not be aviation use.

It's possible shooter or they calibrated to a similar, zero magnets.

You may never find a stem, but should be able to get one modified from say a larger pocket watch but it would require a REAL watchmaker, not just a clean and lube guy.

My Watchmaker is a Bulova School Grad, problem is He's getting on in Years. I haven't showed Him the piece Yet and He just may have a stem in His inventory, who knows.

Great piece Mark.

My 1952 Besfit catalog #101 list's the 22B as taking a stem #056F which is also used in the 19AT movement.

My first impression is that it's a typical car clock. I've serviced quite a few of these, and they are always in bad shape. After being in a car dash (You would lift it out of it's socket in the dash to wind it, or the stem would protrude below the dash)  and banging around for years, they suffered a lot of wear and tear, especially in colder climates, where condensation would wreak havoc. I haven't serviced a Bulova version, but many of the other types, Jaeger, Elgin and Waltham. We had a collection of Aviation clocks, both chronograph and time only, and they were all LeCoultre, and well jewelled. These 7 jewel clocks always wore out relatively quickly, I was told by an old timer who remembers them well in the old cars. 

Stems for these types of clocks are around, but you can also make them, of course. 

Bulova Watch Co signature on both case and movement.  1922 is a little early for these signatures?
