Hi everyone I posted something similar over at watchuseek, but was suggested to hit up this forum instead, because you are the specialists I have this worn out 1960's Carrera lying around and haven't really given it much thought, until I started getting more interested in mechanical watches. It definitely needs a polish and a new front glass. Maybe some of you can help me identify this watch. Of course I have tried to google it first and I figured out it might be this watch: Heuer Carrera 45 Ref. 3647T". However, I noticed that there's a "T" above the Swiss label on those pictures and mine doesn't have that. What am I dealing with here? Would appreciate your input. Also maybe some of you have a guess of what this watch would be worth today.
