This appears to be a 1945 Bulova Officer based on attributions of the other black dial Officers in the database like the one below. This is a yellow gold case with black dial with lumed hour markers and hands. (I relumed the hands). The movement is a 10BS 15 jewels with a dual marked X and triangle date code. I could not find an ad showing a black dial officer so assume this is a tentative. .
Well at least we know it's all original.....here is another example in the database: https://mybulova.com/watches/1944-unknown-3935
Marked as Unknown, which I think for now we need to keep as there are too many differences between what we see in the advert and these watches.

There are already three similar watches in the DB attributed as an Officer so that is why I was going with tentative Officer.
