Exceptional Speedmasters are rare, very rare to find and cherish. This 145.022-74 is by all means one of the best I have seen and it is unpolished. Only thing that it needed was a new pusher core as it was full of verdigris. The movement is very clean, that one pusher core ate all the damage from humidity and did its job. The dial, hands, bezel, case and bracelet are just stunning. I have rarely seen watches so clean from the Speedmaster line. The bracelet is a very rare variant of the 1175 model with flatlinks and 840 matching End links. The only visible mark is on the caseback, from a previous opening attempt.
