I'm not sure what 1973 ad you're referring to. The only ad labeled 1973 in the database is for the 17-jewel Jet Star.
There is a 1972 ad that shows the President and Senator. Both are 23 jewels, both are automatic, and both have the whale symbol on the dial.
The closest in looks to the subject watch is the Jet Star, but the jewel count is wrong for that model (at least per the ads that we have).
