Have tried, but cannot identify this specific model
Can we please see a pic or two of the movement?? That would help a great deal in making an ID.
Hello Chris -welcome to myBulova. Your watch appears to be in pretty nice condition. I've looked through everything we have and can't find any ads or watches that match it, sorry.
For now, Unknown
I also could not find a matching advertisement, and have to go with 1963 Unknown model.
Based on the caseback stamp of 'Bulova International LTD', this watch was very likely made and/or sold outside of the USA/Canda/Swiss markets; based on this excerpt from the 1960 Annual Report:

Absolutely fascinating! So Bulova's connection to Citizen is much older than I thought.
Hi, for various reasons, without going to a watch maker or alike, I am not keen to open it up without the right equipment, to see the movement. I can after Christmas if I get chance find someone to open the back up to see the movement. I suspect the strap is not the original. It was possibly bought in Malaya as he was staioned there around 1961-64, or possibly Europe - as he was in Germany thereafter.
