Very nice watch to have in the family since new.
I believe it to be the Accutron "412", as seen in this 1964 linebook.
Other ad photos seem to show a silver dial, which yours seems to be. The 411 variant also used this case, but had numerals on the dial 3,6,9.
The inside stamp 2527 is the case#; the other stamp I am not sure, possibly from a Bulova service center.
