I believe that this so-called "4th Execution" appeared as a dial, and was then "completed" by being put in a case and getting some hands.

Maybe I'm too conservative / restrictive about this, but I have a hard time calling it an "execution", until we see some evidence that Heuer produced a watch in the specific configuration. Until then, seems to me that it is a dial -- test / prototype / error (GMT dial, missing the "GMT") -- but not an execution of the Autavia.

Perhaps others have learned more about the history of these . . . will be interesting to hear and see more.
