My 1967 Speedmaster Professional appears to be an Ultraman. Just a few moments ago, I opened up the back with my brand new Professional Watch opener and without a bit of challenge unveiled the movement. Here is what I found: Case Back: 145012 67 SP Cal 321 S/N 26X79X7X Is this the real deal???? I think it might be and I have attached a few photos for your review. According to my research the S/N is the exact sequence for the Ultraman. I am beyond excited. Love a few more insights into this. Cannot believe that I may have hit the lottery. I saw one that went for $75,000 at auction. Let me know your thoughts.
