Bulova 1963 International

No import code on movement and no "International" designation on dial. Non traditional case back design bears non-US traditional s/n.

Can you provide a photo or confirmation of text (if any) on the inside of the case back?

Without an ad, based on provided photos and all other contributing factors, I would call this one a

1963 "International"

produced in Europe and offered  for sale outside the US.

There may be an import code on the balance, which is covered by the rotor, so will need to look there also. I agree, it could be an international model, and there may be a case number inside the back as well. I did not find a match in the available ads. Unknown model at this time, waiting for additonal details.

I believe some, if not most Bulova's sold to the international market still had a standard model name.

For this watch, I believe it is part of the Bulova Date King series. Whilst not the watch shown below, the subject watch has similar features.

I just noticed the 'Bulova International LTD' on the caseback. Looks to be a non-USA model, and can be placed under the International model name.

Just to add that we have seen adverts for these internationally sold watches with the same model name as sold in the US.

Panel - are we agreeing on "International"?

For now - agreed.
