While I'm being awkward here's something really unhelpful to work on. I can confidently say that it's round but everything else is up for debate. It looks like the caseback SHOULD come off but I've scratched it once trying, can't see a notch to aim for but there is a groove. I'll show my watch guy in a couple of weeks when I see him next and update.Hope you can make out the "BULOVA SWISS" etched on the back along with the old Bulova goddess. Other than it says waterproof I got nothing else to add sorry.

I'll have another go at getting the back off but much as I know where it looks like it should open there's nowhere easy to insert an opener and don't want to damage anything. Very slim case
I'm reasonably confident that it's early not later 60s, stylistically it reminds me of the 23 BAW (and others) with the gold hour track. International is a definite possibility although I did buy it from the US.
You can always offer me a trade if you like it Geoff, I'm sure you'll have something I like ;)

I have come back to this one numerous times, and am still mystified. Seeing the movement and inside of interior case back would help, assuming one or the other has a date code on it.
"Waterproof" on dial would indicate pre-circa 1968, but case back design strikes me as newer than that. US models switched to "water resistant" in 68 or 69; as for internationally produced models for non-US market, I'm not sure.
I don't believe I have ever seen one marked in this fashion (etched vs. stamped) that old. It may, however be a European produced model I'm not familiar with.
I'm still at unknown model of unknown date
