By the dial it seems to be a Beau Brummel, but I've never seen one with an all steel case before. I also haven't been able to find it in the ads database. I'm hoping the experts here can figure this one out.
It's got the same dial (albeit in white) as this watch: https://mybulova.com/watches/1964-beau-brummell-12138
Very interesting pairing. They look nice together but I agree with Andersok that this looks like mix to me.
Non-Conforming
I have to agree as a Non-Conforming but nothing wrong with the look of this watch. I like the stainless matched to the case and dial. A great looking watch.
Interesting combination, albeit Non-Conforming.
Watches that are assembled from various models using components from different eras are tagged here as Non-Conforming, which is our way of noting that the watch does not "conform' to a standard factory model. Typically the year we assign will be the production year of the case, if known.
