assuming years 60' but s/n not matching with any matrix available on mybulova.com; croc leather strap; case gold color ; internal white color, with clock hands for hours, minutes and seconds.
I'd like to know more about name of model and year of manufacturing
Is there any letter/number date code on the back? I am thinking this might be an international model due to the serial number being unique. If you open it up please take a pic of the inside of the caseback and movement and post it in the comments. There may be a date code inside or at least on the movement.
Certainly looks like an International model. Didn't find a match on my first run through. Will keep looking.
Look intl to me also. I also think this watch might be 14kt or 18kt gold. Has the look of solid gold.
Closest match I could find is from the 1964 International book #153. States 18k gold, but hands are different.
Subject watch is not confirmed solid gold, but leading serial number looks to be a #-.
Going with International model until further details provided.
Nice find Ken. Lets ID as a 1964 Bulova International #516123 for now.
I also agree that the case looks solid gold. What a beauty.
I agree Stephen, based on the serial number I too think it's International.
