I posted this in F71 but it was suggested I check with the knowledgeable folks on this forum. I just purchased a 1970's Rado World Travel from a seller on eBay from South Korea. Perhaps I should have checked before actually winning the auction and paying for it but I did end up having 1 small concern after the fact.
While the seller does seem reliable based on feedback and the watch itself is stated to be 100% authentic (aside from the strap) and looks right; the one thing that concerns me is that I read that Rado watches typically have a serial number and information on the case-back. This one looks like the right case-back for the period but there's nothing aside from the seahorses on it. It does seem very polished so maybe the information was polished off? I think it's from the 70's based on the description and the style but I can't really say for certain since I'm still fairly new to watch collecting and only just discovered that I like vintage Rado watches.
Can anyone shed some light on this and/or maybe know a little more about the watch itself? Either way I do like it (well I haven't received it yet but it looks nice online) so I don't think I'd regret my purchase unless it turns out to be a fake but I don't imagine many would want to fake a Rado from the 70's. Thanks!
