Opened up the wallet a bit this fine Sunday and this is the result. They only made 300 of these bad boys. 44mm Ref.3886
I can't stand buckles so will take the OEM strap off and replace with a beefy deployment something or other. Keeps it mint anyways. Any suggestions what might look good on it? Leather or bracelet for sure, no rubber or natos etc. It's a polished satin finish though so might be tough to match the finish with a bracelet unless it's something from the factory. And even then who knows.
I wouldn't be worried about the authenticity ... I've never seen or heard of a fake Airman.
It should have an exhibition caseback with a rhodium plated signed rotor... The dial plus the rotor plus the limited nature of the watches market and appeal make it a watch not worth faking. It's much easier to run a batch of fake Rolexes or Breitlings and sell every one of them as replicas on Canal Street...
