Bulova 1962 Rawlings
The closest match to this model is the Rawlins. The case looks identical. The Rawlins in the database has a different dial with no sub seconds.
A pic of the back shows a stamp of M2 for 1962. No markings inside the case back.
The movement is a real surprise. A model 8AC with an M1 stamp putting it several years after the range in the database of 49-55.
