This may be a first for the database ... a Sweeping Center Seconds 1935? Trident (Based on movement date symbol).
Nice one. Question: what is stamped on the inside of the case back?

Thanks! Just a lot of service history on the inside ... nothing factory stamped. The serial and case composition is on the outside of the back ---
Please confirm Bulova markings on the outside of the case back, on one of the bevels? 10 AN 15j is correct for a 1935 Trident, making sure the case is marked Bulova.

Absolutely. It says Bulova, with a shield symbol next to it. This is interesting to me, because the shield is 1931 on the movements... but another 1935 Trident in the database has the same shield marking, and Bulova is stamped more centered instead of off to the left like mine. Thanks for making me look deeper into this. I was told these sweeping seconds versions were marketed towards Doctors and Nurses. I appreciate your comments ---

We have discussed the outer "shield mark" previously and have concluded that Bulova preceded by or followed by a shield on the case back outside is a "maker's mark" for Bulova American Standard, rather than a date code. Shield is the "American Standard Watch Case Co." mark.

With the sweep second hand could this be a nurse or doctor watch? Nov 8, 1935 ad

In reply to With the sweep second hand… by Kathy L.
From my research I figured they were marketed to nurses and doctors ... what I didn't realize until you posted that ad , is that the sweeping seconds was new for 1935. Very cool! This is one of my most accurate watches ... gains 7 seconds in 24 hours. Not too shabby for not being serviced in awhile. Thanks Kathy!
We have previously ID'd this model of watch as a Nurses watch like this one. https://www.mybulova.com/watches/1935-nurse-6124
Agreed.
1935 Nurse
Bingo - She's a NURSE!
