Bulova 1973 Accutron

Hi myBulova panel. I hope you can help me identify this watch, which I have recently acquired. The serial number is J826767, and the date stamp on the casebook is N3 so 1973, I think. The case type stamped on the inside appears to be 3076. Before submitting this form I did look through the members database of watches but could only find one accutron with the black arabic raised - that was the accutron 100.

Thank you for your help, Steve.
