I have a lot of love for this particular model Accutron, and I think it deserves a dedicated thread for research. I have compiled a lot of information and photographs which I will add here in hopes to make this guide something valuable to others. Note that "Deep Sea" might sound like it covers a lot of Accutron models. This particular watch has been called "Deep Sea" and the Deep Sea "AB" on mybulova based on advertisements. I will be continuously editing/updating the reference and welcome feedback since I am not the greatest at describing the handsets. This guide does not cover the deep sea "B" and various other 218 caliber diver watches that have the "deep sea" name on them. Additional watch models bearing the "Deep Sea" name will need their own guides since they all have different dial/hand variations.
Most observed watches occur in the M8 to N0 date code range.
