Vintage Bulova information sharing

I don't recognize this.... I've had it for a bit and it's the inly one I've seen.

No markings on the bottom... nothing but the inside.

Another fun pic of a few watches I've rediscovered...

Going though my boxes... figuring out what to hold on to and what to let go... finally got all four of these in the same spot and thought it could be a fun picture.  😁

Hello, I am new here and I would like to know if this watch is dated from 1928 or 1938. Also, is the glass on the back of the movement original?

My wife and I went to see "Ford v Ferrari" yesterday—a very good movie about Ford, race car designer Carroll Shelby (Matt Damon) and driver Ken Miles (Christian Bale) trying to win at Le Mans in the mid-'60s. The guy at Ford who gets things going, at least in the movie, is Lee Iacocca, and though I got just a glimpse of it, I saw right away what watch he was wearing: an Accutron 214. And it makes perfect sense that the go-getter, forward-thinking guy at Ford would be wearing that watch at that time. 

Hi,

I was given this watch by my Aunt however it belonged to my Grandad and his Step Father. The back has the serial 1697845.

Any help would be appreciated.

I cant figure out how to post pictures.

Stumbled on this Bulova/Caravelle case catalog for sale.  Pricey at $99 but this seems like a great resource for someone on this forum.   From the pictures looks like a great parts listing by case. I thougth I would put this out there if someone wants it.  it is not mine just stumbled on it 

Hi, guys.

For the life of me I can't tell these watches apart.

At first I thought it was just the watch face but then I came across this Minute Man example:

I must be missing something.  These cases look identical to me.

Thanks,
