Most Rolex sports model with have a function ... sub/SD - depth rating, Daytona - tachymeter/chrono ... etc
For aero/space, typical functions will be: GMT (PanAm), anti-magnetic (Milgauss), pilot/b-uhren (Rolex has no such history), space travel/moon (Omega territory and Rolex has no such history) .... looks like everything has been covered, except for chronograph to time a speeding aircraft? Not sure what use could there be .....
My money place on daytona ceramic bezel SS , the photo on rolex 2012 invitation has a arrow which look like a hint for GMT2 or yatch master 2 new model since explorer 2 has been out. Is the new CEO going for the revamp sky dweller to be additional new watch to boost the sale.
