Domed Crystal, opens through Crystal, movement is unknown. Says "Swiss" below 6 o'clock. 10k RGP M9 shock resistant anti-magnetic water resistant. Manual wind. Luminescent hands. 3, 6, 9, and 12 number markers are squares. The remaining number markers are two rectangles.
This advert is from 1967, I think this is a Sea King AK. the only thing missing is the 'Waterproof"' inscription on the dial.
Bulova Sea King looks to be correct Geoff. I wonder if the 'Waterproof' has been removed or if its a variant?
Wasn't it around this time in the late 60s that 'Waterproof' was not allowed by law as to not misrepresent to the consumer? Perhaps the lack of the term on the dial is a result of a law at that time.

You're right Ken, I think it was 1968 that 'Waterproof' watches became 'Water Resistant". Forgot all about that!
