Hi Nic, welcome to myBulova. Accutron was introduced by Bulova in 1960. it was a revolutionary step in watches known for it 'tuning fork' movement which kept the watch extremely accurate. The tuning fork heads al the opposing coils you see near the bottom of your last photograph. The original watches didn't have winding stems but had a time setting mechanism on the watch back. The second generation movement had a winding stem at the 4 o'clock position. By the late seventies the tuning fork movements gave way to quartz movements and the rest, as they say, is history.
I don't see and exact match in our advert dB. Generally these watches didn't have proper names like other Bulova of the period bust where known only by a model number. When we can't find the exact model we classify them as just 'Accutron'
1975 Accutron is my ID vote.
