Any one can help to find what is this model?
I'm curious if your watch has a missing center sweep second hand?
The International Model #57 11 10 shows what I think is the subject watch.

I agree with the ID and it does look like it is missing a second hand. 1979 Bulova International Model #571110

Thank you guys, Today I brought it to service and asked same question " it does look like it is missing a second hand", technical check it under magnifying glass and said "the original there hasn't got the second hand".

Thanks for checking, but I'm not sure if they are saying it's missing a second hand, or the watch never had one / doesn't use one.
Hello, This is service quote from service centre: ***start quote*** Bulova 709/cal. 7EDAD/17j - 1 X Complete overhaul of the watch movement, cleaning and lubrication, and timing to mfg specs. 1 X Refinish Case to Factory Standards. Parts List: 1 X Remove rust from winding wheels and polish. ***end quoted***
And he confirm model number is 709. Regards,
Without center sweep I'd say Unknown. I'm OK with the 57 11 10 ID though.
1979 Bulova International Model #571110 looks like a good match
None of the other Bulova's in the data base with the 7EDAD movement have a seconds hand, so this one most likely didn't have one either.
1979 Bulova International seems the best ID to me. Clearly it does not have a second hand so it is not the model 571110.
I default to
1979 Bulova International
