Before I knew anything about Speedmasters. I only knew they were known as the Moon watch. I had purchased a Speedmaster Reduced before that and wanted the "real thing" so to speak. My own research has given me confidence this could be a fine example, but I thought I would throw it to the wolves so to speak and see if you guys have any comments. I got the Extract last year and found it went to an interesting destination....Ethiopia. The band is a 1171/1 and 633 ends. I put on the clear back, which is nice to look at. Crystal is lightly polished but has Omega symbol, though can't be seen in pics. Got a Timegrapher for Christmas, so including a pic of what I think is a very nice regulation(0,-1,+1,0,0,-1,+2), though a bit of BE(1.5)....not too bad for 50years. It all appears right to me, except for the replacement band. Given the values of these are increasing rapidly, I hesitate to wear it (choosing the Reduced instead).
