Air King search

[Chulander]

Hi everyone,

I am myself a proud Daytona owner, and am in the process of helping a colleague track down his dream watch, what I believe is a 5500 series Air King.

In particular, the model he's looking for has a red dial, exactly like this:

http://www.ebay.com/itm/MENS-VINTAGE...item3a907cef6a

Can anyone tell me if this watch looks legit, if the seller is a good one to purchase from, and if the price is reasonable?

I've also heard DavidSW mentioned MANY times on this forum. Should I consider them as a good alternative to eBay for this particular watch?

Also, for the Air King specialists out there, is there anything I should be looking out for for this particular model?

Thanks so much in advance.
