My mother in law gave me this Bulova watch as a wedding gift a few months ago, since she knows I have a soft spot for vintage things . She told me she bought it in New York in the early '60s, and I see that's accurate since it's a 1961 model.
It's 10k RGP and still works perfectly.
I'm pretty sure I've checked all ads we have here, and I also searched quite a lot online, but could not match it to any model.
As you can see its shape is a teardrop, and the closest resemblance I could find was with the First Lady from an 1961 ad, but it's not quite the same (not the same number of jewels, different numbers in the front etc). In any case, the only ladies Bulova with a teardrop shape I've found was First Lady.
