18k gold Aerojet
1964 linebook has this as an international model (as shown on back case) and lists as model #516203
I would ID this as a 1964 Bulova Aerojet "516203"

Thanks for the reply. I still haven't been able to find an exact match though. Is there a reason as to why the 516203 has a calendar magnifying glass and the "Aerojet" logo has the lines on either side when my watch doesn't have either?
Agree with the Aerojet 516203 ID.
I suspect this watch has had some modifications; crystal replaced lacking the magnifier, dial reprinted - unable to replicate the original Aerojet and the wider Automatic print.
Sounds plausible that it may have been modified. Thanks for the explanation.

Any idea what it's valued? The ideal mint condition, 100% original Bulova value?

Sorry Willy - we are not able to give appraisals on watches, we just aren't qualified.

Is there any way to look up the original price when it first came out?
