Hi everyone. I am seriously considering buying a 1984 speedmaster 145.022 from a reputable seller in the uk. Can anyone give any advice on what to look for. I have added a picture in case anything pops out as off. Essentially I am not concerned that it’s a fake I just want to know if anyone can see any reason not to pull the trigger. Is the bezel correct that kind of thing. I have looked online but it’s a bit of a minefield. I appreciate any info.

Also does anyone know if I can get additional links for the bracelet from anywhere? Is it as simple as ordering through omega?
