Evening gents, I've been contemplating purchasing a vintage Longines conquest for some time, but don't know too much about them or where they generally price, so I'm concerned about my ability to spot any potential issues before purchase. I don't necessarily need a perfect specimen to enjoy owning/wearing the watch (as evidenced by the vintage AP I listed in private watch sales), but I'd at least like to be aware of any issues before purchasing. I have linked to 3 options below that suit my tastes and was hoping to get some feedback on their authenticity/condition, price, etc. https://www.chrono24.com/longines/l...age-conquest-automatik-ca-1958--id5464416.htm https://www.chrono24.com/longines/conquest-automatic-9001-enamel-caseback-18k-gold--id4225900.htm https://www.crownandcaliber.com/buy/longines/longines-conquest-vintage-wan21736 On the first, I recognize that it has a SS case back vs the gold case. Was this typical or is this likely a franken and that and that's why its priced so far below the others? Separately, are the other two above market or is that generally where good examples price? Lastly, I'm located in the US and haven't purchased a watch from outside the US before. As far as I can tell, the last two options look very similar in condition, except the one located in Italy is obviously cheaper. Will the savings end up disappearing if I have to pay import duties? Would also likely be waiting longer right? Thanks for the help, greatly appreciated!
