Additional Information: 

I guessed at the year based on movement model. Wondering about this case, did Bulova produce salesmans display watches, or is this possibly a marriage? Case diameter about 33mm, case back appears to be base metal or similar composition, with acrylic crystal. Movement has small 48 marking on winding rotor, and either BXW or 8XW on balance bridge. Only markings I can find.

Bobbee Good eyes.  I sure can't make out a "48".  Gary  That's a 48 on lower right picture of rotor (after Bulova Watch Co and below the 17 jewels stamps)?

It potentially being an early 48 model would make sense to have a saleman see-thru back case. I can just see the salesman rocking up to a jeweler, watch in hand showing how the movement works. without the need to take the back off.

I love these clear backs and wish all mechanicals had them. I'm forever showing of mine to friends and family and hate having to dissemble when I do it.

48 Duo Wind gets my vote. (tentative of course)

Will we ever know? It looks like an "8" on the rotor, but the owner seems to be ignoring or maybe misinterpreting all requests to tell us what it actually does say on the rotor, are the numbers "48" there, or is it something else?
Please let us know , Gary.

Bob, I don't think Gary is ignoring anyone as it's been less than 24 hours since his last post.

The F410, 415 (sweep sec) Bidynator dates to 1942,  just for background info. This doesn't mean Bulova used it immediately, obviously, but it was around. The patent wasn't granted to Felsa until the following year, 1943, but was filed and pending prior to that. Quite a few watches in the 40's took advantage of this well made new movt.

Yes, that is the number 48 on the lower right of the rotor, below the 17 jewel marking, it is very small. I made several attempts to get a clear photo to show it, but these are the best I could get. By the way, I worked today.
