i have recently bought at an auction, based on the photographs that did not include pictures of the movement, a speedmaster 145.022-st71 with stepped dial. The stepped dial was not visible in the auction pictures, so it came as a pleasant surprise when I noticed the stepped dial and the st71 inscription. The serial number is 32855xxx and seem to match the st 71. However, the watch seems to be very untouched and the markers have not aged at all and still seem to be very white (in real whither than in the picture) for a speedmaster of this time. This made me wonder. I would very much appreciate any feedback on the originality of this watch. Thanks in advance!
