Hi guys, slowly but steady, I'm in a fever of collecting old Speedys You aren't completely innocent... thanks for that! I got an offer for a 145.022 - 69. serialnumber 3131XXXX I could trade my Heuer Autavia with some money. A small "problem" is the caseback: First, it's a caseback for a 105.003 - 65, second, it looks a bit too new to me. Could it be a fake caseback? The seller/trader said, that it could be changed by time, when the watch was serviced... I know the dial is not the best one (are the lumeplots are a no go for you?), and the case is polished, but somehow, I like the watch. What are your thoughts on this one? Thanks for your help!
