Thanks to the database, looks like I just acquired a 1969 SeaKing. Thanks to https://mybulova.com/watches/1969-sea-king-7570 I was able to positively ID :)
Now the challenge is to get it open and cleaned.
Thanks for doing the initial legwork to ID. Image below is from the 1969 linebook.
1969 Sea King
The variant letter designation depends on the color of the dial. Can you confirm dial color? Gilt (gold) or silver?

Definitely a 13424-7Y. I put it on the timegraph last night, and in face up it's running -35s/day, 230 Amp, and 0.3ms BE !! So assuming the it's an 11AL, with a lift angle of 50, not bad for it's age and given the muck I had to clean off the case, probably not serviced in years.
If I do open it up, I'll post pics of the movement. Anyone know where I can source a new crystal ? And which one to order :) ?
Sea King is a good match
1969 Bulova Sea King (variant upon confirmation of dial color, silver or gilt)
1969 Bulova Sea King "AL" based on his confirmation of a gilt dial.
