Air Kings on eBay

[rolex170]

Hi All,

I'm new here and looking to get my first Rolex. I really want the Air King, blue dial with stick marks so I'm going the pre-owned route since Rolex no longer produces this version. I found a couple on eBay and would appreciate any feedback on real vs fake.

this one is priced well, but I'm not sure if it's actually a deal?

this next one is pricier, but it is newer...no papers or boxes with either..

which would you choose? the older one appears to have a 1520 movement, the latter I think has a 3130? Movements look real to me, but would appreciated a 2nd opinion...I've read going older is better to avoid fakes, but I'm always open to advice on this topic.

Thanks again...this forum is so informative...I've learned so much about rolex watches!
