This is a 31MM 1968 Bulova 10KT Yellow Gold RGP Automatic. It has a gorgeous silver linen "pizza slice" dial with gold Bulova and 12, 2, 4, 6, 8, 10 minute markers.There is also a gold ring with second marker dots around the outside of the hour markers. The outer case bezel is textured.
I know I've seen one of these before, but can't find one in the database or ads. Very cool watch, but at this point an unknown for me, but I'll keep looking.
my vote is Jet Clipper "J" nice example

Wow. you are good! Thank you. I am still adding some more of my Bulova's to the my watch database. Only a few more but this has been a great experience working with you all! Thanks again.
Good ad find; I agree with Jet Clipper 'J'. A rather stylish looking watch.
