Kind of looks like the 1962 Squadron "L" in the database. 1962 verses 1964?.
The one listed in the database does not list the movement other than it is a 17J
The sub-seconds bit is different as are the hands.
Its a start.
This sure looks like the this watch from a 1963 ad.
missed front photo of your watch, it´s important for identificatrion
OOPS. Thought the reply was the watch...disregard.
