Morning, I have just taken possession of my father’s Speedmaster and I’m trying to pin down the exact model and year. I’m hoping for some help as I’m getting confused! The watch was bought by my Dad whilst he was serving in the RAF in Germany and he believes it was 1969. The watch is a pre professional but has crown protectors. It also has the T marks either side of the Swiss made lettering. I’ll attach some photos to assist. The bezel is missing and there’s damage from a drop to the stopwatch controls. Any assistance greatly received!
