Here I have my Grandfathers watch, passed down to me, I think it's lovely. After a little research I believe this to be made some time around the 60's. I'm not sure on the material but it's gold in colour. The only code I can find is on the rear of the case. It also has a ballerina logo engraved on the rear of the case. I'd really appreciate if we can find out more information on this. Thanks
Hi, it would appear to be an International model #512206 from the 60s.
You would need to locate the datestamp from inside the case or from the movement to pinpoint the year.
Linebook 153 from 1964

Agree this is a Bulova International Model #512206. Need to confirm date.
Thanks for the swift response team, very much appreciated. I will investigate further and locate the datestamp and give you an update
Agree with Bulova International Model #512206 pending date confirmation.
