I am new to this forum so just saying a quick hello. I seem to have developed a keen interest in Speedmasters. I previously bought and still have a couple of Tags but for me the history of the Speedmaster and the NASA connection give the watch something that is rather unique. I have a modern 3570.50 which is an excellent daily wearer. An older 1967 cal 321 145.012 which I believe to be pretty much original except for the bezel. I am not sure what the next one should be? I was considering a 1968 transitional piece? But now I am leaning towards an earlier 105.003, straight lugs and no crown guard kind of watch. Something like this

Considering how the price of Speedmasters is going I thought 4,100 Euros/5,400 USD wasn't a bad price? Any comments much appreciated.
Best regards
