Rubaiyat works for me.
What's also interesting here is the styling of this model with the new 2017 versions.

1965 Bulova Rubaiyat works for me.

Ad is a match and price ($395) would reflect diamonds on bezel and solid gold case.
1965 Bulova Rubaiyat looks like a match to me as well.

Slight difference in the recessed second hand area, but I'll go with Rubaiyat.
Just started getting notifications you all were reviewing this post! Sadly, about 6 months after posting this the watch was stolen from my home... Someone thought highly of its street value I suppose. Not Realizing it had an importance of heirloom value for me.
Sorry for your loss. Found this ad. Confirms 14kt white gold and available in white and black dial version. Note the recessed second hand.

It's good to see that even back then Bulova paid homage to their roots.
