Given the trend for ever rising prices this looks like a good buy.... Or am I missing something obvious? http://www.chrono24.com/omega/speedmaster-321--id4158737.htm
Yes ist is...Replacement crown and the Caseback has some scratches, but with 1506/16 it is a good buy. I think it doesn't take to long and the watch is sold.
Did you know there are literally THOUSANDS of EXCELLENT watches OTHER than Speedmasters? There are even other very cool brands than Omega! I know, it will take a while to sink in.......
