Could it be a Data King model?
CASE: diam 33 mm; Stainless Steel Case; Self-winding; Waterproof; Anti-magnetic; Shock Resistant. 2622 inside.
DIAL: with calendar.

Certainly a match for the Date King shown below. No variant, but I'm sure we'll be able to find it. I suspect the dial has lost some of it printed detail.

Found this that shows a clean dial like the subject watch, so maybe it hasn't been 'over' cleaned.
Bulova Time Center "F". Although this model also sports the calendar strap.

Possible Date King "PE".

Also a Date King "TT" (again minus the dial printing)

...and yet another option.
Bulova Date King "PM", note the plain dial configuration as per the subject watch (although it might say 15J in the details.)

Muito obrigado Administrador pelos valiosos comentários que me enviou. São uma ajuda muito importante para todos os que gostam destes simpáticos relógios Bulova.
I will throw another one in there. In the 1969 Linebook we have what I think is the watch listed as a Bulova Sea King "CO". The fact that the case is marked Waterproof makes me think this could be an option but I do not see automatic in the description. Based on this I am leaning towards Date King unknown variant.

1967 Date King looks like a good bet.
